Signs That Indicate Roof Damage

Signs Of Roof damage (adco)

Roofs are prone to deterioration, and factors such as hail, sun and wind are known to cause problems. Understanding the signs to look out for will enable you to notice signs of roof damage. Here are what to look for:


Normal rainfall cannot damage the roof unless it has already been undermined by other adverse weather conditions. In case the shakes or shingles are damaged, water might find its way through the cracks and holes. On the other hand, heavy downpour might wash away the granules, impairing the shingles.

In case your roof was designed poorly or some areas are inverted or flat, the pooling of water on the rooftop might spike potential problems. Surprisingly, an inch of rain water has an equal effect on the roof as that of five pounds on the roof. An average roof is designed to withstand an average of 20 pounds of weight. That means that it can only stand four inches of water; in case more pours on it, the roof might collapse.


Roofs are made to withstand tension and weight by disbursing it over the rafters or trusses. When tough winds hit the roof, they will not do so uniformly. Instead, their major effects are felt at the corners and edges. As the winds grow stronger and hit harder, the roof will weaken eventually thus allowing it to heat beneath the roofing material. In case the insulation parts are exposed, you will start noticing leaks that will eventually damage the house.


Roof damage from hail

Hail can be either destructive or harmless, depending on how severe the storm will be. In case the hailstones are too large, they might knock off granules from the shingles. The result is faster deterioration of the shingles over time, and might cause leakage. The pounding could also compromise the membrane that lies below the roofing material. That makes the whole roof to be more prone to water damage.

Excess heat

If part of your roof is metallic, you ought to consider the effects of excessive heat on your roof’s stress points. As the metallic parts are heated by the scorching sun, the panels will contract and expand. This results in excessive stress on the fasteners and seams.

Solar panels

With time, solar energy has become a popular option. However, solar panel installation might cause stress to the roofing system such as the shingles, rafters or sheathing. Installers are thus advised to stick to manufacturer’s instructions and directions. Discuss the implications of the installation before choosing to have the panel installed.

Tress and debris

It is possible to notice when a tree hits your roof, but you might never realize when branches and small twigs fall on the rooftop. The small debris slide off without leaving any evidence on the roof. Whenever any material falls on the roof forcefully, it might damage it. The damage is bound to fasten your roof’s deterioration. This leads to leakage and other issues with time.

10 Most Common Rooftop Safety Hazards

10 Most Common Rooftop Safety Hazards

It is everyone’s responsibility to look after their own health and safety and that of others when they are working on a roofing project. Making sure that you are aware of any potential hazards is a good place to start as once you know that these hazards are then you can start to think of ways to avoid them. Here are the 10 most common rooftop safety hazards:

Stability Of The Roof

If the roof is unstable then there may be risk of collapse under a persons weight. The roof should always be checked before more than one person goes up there.

Placement Of The Ladder

Most roofing accidents occur because the placement of the ladder is incorrect. The feet should always be secure and the top of the ladder should be tied to the roof if practical.

Weather Conditions

Shingles on a roof can become slippery if it has been snowing or raining and this can make falls more likely. Snow can also add extra weight to the roof. If the roof is too wet then any work should be postponed until the weather conditions have improved.

Holes In The Roof

The roof should always be checked for skylights that have not been covered up or holes of any other kind. Falling through the hole in the roof could cause serious injury and is something that can be easily avoided by carrying out a few simple checks.

Losing Awareness Of The Edge

It is easier than you think to lose awareness of where you are in the roof and falling from the edge can lead to fatalities. Even the most experienced roofers can lose track of where they are on the roof and find themselves stepping too close to the edge on occasion and so it is important to take a moment every now and again to stop and think about exactly where you are.

Improper Training

The training that you undergo before you start working on roofing jobs will teach you all you need to know about staying safe when you are working on a roof. If the training has not been up to standard then it may be harder to keep yourself safe as there may be important safety elements that you have not been taught and are therefore unaware of.

Improper Use Of Equipment

You will need safety equipment before you go up on the roof to help protecting you but you will not get the benefits of this protection if the equipment is not used properly. Common mistakes that are made when using safety equipment include the lanyard being too long and the tie off point being too weak.

Poor Line Of Sight

There are many things that can block your sight when you are on a roof such as chimneys, ridge vents, and even other workers. Maintaining a good line of sight is important so that you know where you are in relation to the edge of the roof and so you can see any other potential hazards that may be on the roof.

Pitch Of The Roof

Greater care will need to be taken on roofs with a steeper pitch as you will be more likely to fall on a roof like this than you would on a flat roof. There is also more danger from falling shingles on a sloped roof so you will want to make sure that all shingle bundles are properly secured.

Split Level Roofing

Split level roofing brings more safety concerns because it is possible that the highest point of the house is further off the ground than on a single level home. There is also a greater chance of falling from the side of the roof as these areas are unlikely to have any kind of barrier that could prevent the fall.

Personal protective equipment (PPE) needed whenever you work on a roof and it is vital that this is used correctly. If an accident did occur and there was a problem with the protective equipment then the consequences of this accident are likely to be more severe. If you are unsure about how to use any piece of PPE then you should ask someone to help you. PPE is there to help you but you also need to take some responsibility for your own safety.

How Infrared Technology Can Resolve Roof Issues – Thermal Roof Inspection


A commercial and industrial roof is subjected to extreme heat and moisture. It’s important to point out that a commercial roof replacement project is one hefty cost that cannot be taken lightly by building owners. Fortunately, an experienced commercial roofing contractor can check and critique the insulation under the membrane of the roof with ease. This exposes viable cost-effective solutions for building owners.

The wavelength length of thermal or infrared energy is extremely long. This is the primary reason why this light cannot be seen by the human eye. Scientific studies have proven that the wavelength of thermal or infrared energy is part of the electromagnetic spectrum that is considered as heat. Thermology excels when it comes to recording the thermal or infrared radiation with the aid of an infrared camera.

According to Adco’s Infrared Moisture Analysis, an infrared camera can pick up infrared energy and transform it into an electronic signal within a matter of seconds. The electronic signal is carefully processed to create a sharp thermal image on a compatible video monitor and compute precise temperature calculations. It’s worth mentioning that infrared cameras have sensitive sensors called “bolometers”. Bolometers are designed to scan infrared and produce a picture that can be seen.

Some people are under the impression that they are looking at temperature readings when they look at the image. However, they are actually looking at a representation of the thermal radiation on the surface. It’s critical for one to know the difference!

Extensive training is essential when it comes to helping a commercial roofer recognize false indications. Having a deep understanding of the science is the key to taking advantage of this impressive technology. Commercial roofing contractors (like ADCO ROOFING) will use an infrared camera to interpret roof conditions and share their knowledge with building owners.

The Advantages of Infrared Technology

  • Locating Wet Insulation

Wet insulation can is costly because it increases monthly cooling and heating bills. It also weakens roof materials. It’s not unusual for some commercial building owners to suffer from thousands of dollars in repairs due to wet insulation. IR technology can detect wet insulation, and a thorough roof survey can point out the damaged areas that should be replaced.

  • Detect Moisture

The powerful rays of the sun can help us detect water trapped in a roofing system. The concept of heat capacity plays a vital role in the process. Water heats up slow when compared to other substances, and it holds heat for a longer period of time. When the sun rays heat up the roof, water is slow to heat when compared to roofing material. The roof can be inspected at night because water cools off slower than the roof.

  • Finding Leaks

It is challenging for any commercial roofer to find leaks in a newly installed roof. For instance, leaks can take place below the outside intrusion point. This could be hundreds of feet below!

The law of physics points out that water is not immediately absorbed by polyisocyanurate insulation. It could be easy for detect roof moisture, but the challenge lies in finding the source of the leak.

  • Quality Control

A commercial roofing contractor can inspect the roof after a job is completed to make certain that water has not infiltrated the roof system during the project. Missing this crucial step will only cause problems for the building owner. Experienced contractor can lower or eliminate callbacks by checking for bad seams. Everything can be detailed with video recording, infrared imagery, and digital photography.

At ADCO Roofing, we are committed to surpassing our customer’s expectations. Our polished technicians will inspect the roof thoroughly before employing our advanced infrared technology. For example, we will do a thorough walkover before using our equipment. The walkover offers many safety advantages that cannot be ignored. They uncover rotting areas and many other safety hazards that pose a serious risk.

Visibility is important when it comes to inspecting a commercial roof. This is the main reason why inspections are conducted before it gets dark. This helps us focus on the housekeeping of the roof. From our experience, you are bound to see significant damage if you spot poor housekeeping.

Perfect Time For Preventative Maintenance On Commercial Roofs

Preventative Maintenance On Commercial Roofs

The only way you can be sure that your roof is doing its job all year long is to schedule periodic inspections which will lead to proper maintenance and repair. A great time to pencil in the needed inspection and maintenance is during the fall months. The hottest months of the year are gone, and you may experience lots of rain coming your way in Los Angeles. The roof is ready to reveal any weaknesses, structural damage, or other issues that may impair its performance as we move into winter.

Timing Your Roof’s Inspections

The roofing industry suggests that commercial roofs be evaluated twice yearly, and fall fits into that schedule very well. Your commercial roof has taken a beating over the hot summer months. The sun’s UV rays, winds and debris from trees and structures on the roof have taken their toll.

Fall is the time to investigate whether routine maintenance will take care of the problem of if a more intensive set of repairs needs to be done. Taking the time to complete these steps rewards you with a well-functioning roof that will last for many more years.

Consult A Professional

Best practices and outcomes indicate that you need to have an inspection completed by a licensed roof contractor in Los Angeles. Although you could give your roof a once-over visually, roofing experts are trained to look for the signs that indicate a roof is damaged, aging, or failing because of improper work earlier in its lifespan. Be sure the roofing company you engage is familiar with commercial roofing issues, which can be very different from residential roof problems. ADCO Roofing in Los Angeles has extensive experience with commercial and industrial roofing systems.

What To Expect

  • Interior Evaluation

Do not be surprised if the contractor starts the inspection inside your building. The best indicator of a failing roof is often found within workspaces, storage areas, and other areas of your business. What the inspector looks for is any indication that water has found a way inside. He or she will scan carefully for staining of walls and ceilings, buckling of floors, mold growth anywhere, and any standing water or puddling.

  • Exterior Evaluation

Once the interior has been viewed the roofing contractor will spend time on the roof itself. The waterproof membranes will be inspected foot by foot, looking for any obvious penetrations or more subtle signs of water incursion, liked pooling or sagging spots. The inspector will check all seams, flashings, and fasteners, mechanical or adhesive, for missing parts, improper application, or wear and tear.

The edge of the roof can show its age faster than other areas, so the inspector will take time to view it all around the building, looking for any breaks, notches, wear, or other damage that could be letting water enter the building.

If penetrations or worn areas are found the inspector will determine whether they need repair or a more major tear-out and replacement procedure. The biggest concern in the fall is to get your commercial roof ready for the cold and rain that is just over the horizon. Your roof protects the building’s insulation, and any waterlogging of that material means the insulation cannot do its job. Your premises will be harder and more expensive to heat, and the comfort of your staff, clients, or customers will be affected adversely.

  • Repairs And Cleaning

Once the issues are identified, a reputable commercial roofing contractor will make the repairs and complete the maintenance necessary. You want this done before the rainy season so that all is set and ready to go to get you through the winter into spring. A quality roofing contractor will also be certain to clear all debris from the top of your roof, either from the repairs and maintenance, or just the normal deposits from trees and structures in the area.

You will not be disappointed in the results of a carefully planned commercial roof evaluation. The peace of mind you receive is worth the expense, and you definitely will avoid major costs down the road if you arrange for this to be done regularly.

4 Signs Of Critical Issues On Your Commercial Roof

critical issues on your commercial roof


It is crucial to make certain your commercial roof stays in the best shape possible to avoid potentially expensive and time consuming repairs. To help you do this, watch out for the following four things. If you spot one or more of them, be sure that your commercial roof gets immediate attention.

1. A Leaking Roof

Leaking is one of the most obvious signs of a damaged roof. However, you may not notice a leak until it has already caused significant damage. This is why it is so important to schedule regular commercial roof inspections.

If the inspector identifies any areas that have the potential to cause a problem, keep a close eye on them. By being proactive, you could prevent water pooling and damage that can put a strain on your roof. You are also more likely to save yourself the cost of water cleanup and damage repairs.

Typically, roof leaks occur around the exterior edge of the roof or at the site of parapet walls where flashings have been installed to protect the edges of the roof membrane cover. If these flashings are installed incorrectly or become damaged or loose due to strong storms and winds, it can leave parts of the roof cover exposed, allowing water and moisture to seep into the roof and building.

Penetrations, such as those from pipes and drains, puncture the membrane of your commercial roof and are prone to leaks. All roof penetrations should be properly secured to protect your roof from water damage.

Additional examples of penetrations include gas lines, conduits, HVAC units, pipes, drains, hot stacks, and other object routed through the membrane. Be sure that every area of roof penetration is carefully observed by an inspector and that the area is kept water-tight using field wraps, rain collars, pitch pans, flashing, or pipe boots.

2. Pooling Water

Also referred to as ponding water, this is stagnant water that has been allowed to sit on a roof for more than two days. This is especially common in commercial roofs because they are often flat, allowing the water to pool and penetrate the roofing membrane.

Although flat roofs frequently have a bit of a slope, pitch, or tapered rigid insulation to prevent pooling, this isn’t a foolproof system. This can cause damage to all areas of the roofing system.

In addition, UV rays from the sun can heat up a bituminous roofing system, causing gaps to form in the membrane which clog drains. When performing a roof inspection, your inspector should look for drains that have become blocked.

3. Bad Roof Repairs

In some cases, your roof may become damaged due to using the incorrect or improperly installing roofing materials. Unfortunately, in this scenario, your entire commercial roof will likely need to be replaced. This is because patching and repairing “bad” spots simply won’t help your roof’s long term performance.

4. Subpar Workmanship

If you have hired a roofing company in the past who didn’t deliver the high quality results you deserve, it may quickly become obvious. It is not unusual for some roofing companies to compromise on material quality to lower their estimate and make it more attractive to the property owner.

While the owner may not spend as much in the beginning, roofing costs will quickly rise with each repair. It’s true that most roofing materials are under warranty, but they can easily be voided if subpar workmanship is identified.

Subpar workmanship may be the result of inexperienced workers or an attempt to cut costs. In some cases, it may be the result of using or installing the wrong materials.

For example, if fastening is not done correctly, shingles can blow off, leaving the roof’s membrane exposed to the elements. In other cases, the problem can be related to improper ventilation.

Even the highest quality roof installed by the best roofers in the business will need repairs at some point in its lifetime. Make certain your commercial roof is routinely inspected and maintained to identify any potential problems as soon as possible. Then, make arrangements to get them fixed immediately.

Roofing Repairs

Most Important Commercial Sustainable Roof


Commercial establishments are increasingly going for sustainable roofing solutions in a bid to save on costs and follow the regulations of environmental bodies. While many parts of a property make up a green building, the roof is one of the important ones because it acts as a barrier between the building’s interior climate and the natural forces outside.

There are a few considerations which are crucial to make when you are going forward with sustainable roofing for your commercial building. It is a must you know about them.

Sustainable Commercial Roofing Considerations

You may need to redesign your entire roof or just make minor changes. Either way, you need to hire reliable roof contractors for the job because you cannot afford a single mistake. From HOA multi-family building roofing, industry roofing to commercial roofing, we can do it all.

Roof inspection

Worried about the rainstorm and its damage to the roof? You need to call reliable roofing inspectors, so they would carry out a thorough roof inspection. Sometimes, the visible signs of roof damage may not be much, a reason you would do good with a roof inspection every few years.

Roof maintenance and repair

Every roof needs repair time to time. It may be a single tile falling off or a part of the roof being damaged – if you spot anything wrong, it’s a good idea to call in the experts fast. It isn’t as costly as you think, and you may want to get it done sooner than later.

Roof replacement

Every building needs a new roof every 20 years or so. Old roof structures could be dangerous, and the right roof replacement experts can just make the process a lot easier.

The Top Considerations to Keep in Mind

1. Insulation Capacity

The roof is responsible for preventing the heat from seeping in your property. Generally roofs are measured through Energy Rating of ‘R’ value which denotes its resistance to heat. So naturally, a higher resistance means less heat coming in and more of air conditioning remaining in.

It saves you on utility bills, makes your building energy efficient and helps the environment in the end. Make sure you go for roofing solutions with higher ‘R’ values all the time!

2. Energy Efficiency

The choice of the roofing material determines the energy usage of your whole commercial building. When you go for energy efficient roofing material, choose something that will save energy and ultimately money. Different climatic areas require different types of roofing material to conserve energy.

For example, in hot regions just like Los Angeles would benefit from reflecting off the heat whereas in cold ones, something absorbing heat would be ideal. EPDM is a flexible material which can be used in both hot and cold climates. The black properties of the material are suited for cold regions and the white or reflective surface suits sunny areas.

3. Condensation Threat

Warm air rises up and contains water vapors with it. The same happens in your commercial building and the moist warm air comes in contact with the roof which is generally cooler. This leads to condensation which can damage the roof and its energy efficiency. Before getting a new roof or going for a repair, be sure to check for the condensation levels and atmospheric factors both inside and outside the property.

4. Lifespan of Roof

A long lifespan of your roof means lower costs and optimum performance of the roofing materials. But the roof is under constant threat from elements like sun, rain, hail, a storm and snow. You need to carry out regular maintenance of your roof to get the most out of it.

Don’t miss out on roofing repairs and don’t wait for it to get worse – you need to take action immediately, and these simple steps will help you get sustainable roofing the way you want it.

Recovering vs Replacing Your Damaged Roof?

Recovering vs Replacing Your Damaged Roof


Though your commercial roof providers may guarantee you a lifelong impeccable performance, unfortunately sometimes it is far from the reality. With time, your commercial roofs may start developing minor problems and other issues.

Also, imperfect installation along with a poor maintenance may affect the longevity of your roof. Often, it might not cost a lot when it comes to roof repair, if you identify the problems at the very beginning. If the membrane is in good shape or the roof has good insulation, your repair costs will probably be a minor one.

You can see hundreds of such roofs in dire need of attention and repair. Some of the common roofing problems that we commonly encounter are:

  • Leakage: Damp portions and ceilings and walls getting slowly discoloured are one of the earliest signs of leakage and water getting seeped into your building.
  • Lack of maintenance: many people often neglect the primary tasks of inspecting their roofs on a regular basis. If you keep an eye on the details, you can actually save yourself from repairing issues,
  • Overflowing gutters: damp, rotten wood and other things like damaged brickwork can easily block your gutters. So make sure you get your gutters cleaned regularly.
  • Pests: birds often pick off tiny bits of your roof and also add some of their chosen materials like stones, sticks and their droppings.

How To Go About Replacing Your Roof?

However when you have a damaged commercial roof, you are generally left with around four choices:

  • Repair: some of your commercial issues may actually be minor and more or less simple. You may see that it is more or less in good shape with proper insulation. They would demand a repair which would eventually extend its life and you don’t necessarily have to replace it.
  • Re-cover: you may think of re-covering your roof which is one of the most effective ways to mend an almost sound roof. If your roof has one membrane, you can think of putting another on top of it. This is economical and does not involve huge costs or massive disruption. You may also get new extended warranties of your roof.
  • Coating: Coating extends your roof life. Your building is exposed to heat and UV rays over the years because of which materials may break down. Coating increases UV and waterproofing protection for the roof.
  • Replace: And if nothing else works out, replace. Replacing is the only alternative if you have already re-covered the roof once before. It ensures long term benefits. So if you plan to keep the building for a really long time, the best option is to replace it.

Last but never the least comes the importance of having a regularly maintained roof. This would ensure that the problems don’t escalate. Research has shown that in many cases, huge amount of money and effort on repairs could have been easily averted with simple inspection. So, just be aware and watch out! For instance, let’s talk about roof restoration!

Roof repair can be quite costly if you do not act in the beginning. Roof restoration costs depend on the extent of damage to your roof, but will be significantly lower than say a roof replacement cost.

Roof cleaning – Cleaning your roof doesn’t just help your building look good it helps to identify any roof damage in the initial stages as well. The right experts know just what you need, and can help you with your regular cleaning needs.

Warning signs of Roof Damage:

Even if you get a slight hint that your roof may be damaged or is falling apart, then you should look for a roofing contractor to hire. The following are indications that something might be wrong:

  • Aged Roof: If your roof was built a long time ago, it is time for some standard repairs.
  • Damaged Shingles: If the shingles are curling or buckling, then you might be in trouble. Also, keep an eye out to see if all the shingles are there.
  • Daylight filtering in: As poetic as it may sound, this means that there are cracks which need to be taken care of as soon as possible.

Your Roof’s Condition Can Affect Your Property Insurance Coverage




You may not know this but if your roof is in poor condition your insurance company may require that an actual cash value percentage of the room is excluded from your insurance policy.

If your roof is not in the top position than this cash value can be a lot less. They may exclude coverage for the entire roof. Other companies may only cover portions of the roof that tend to be newer or in good conditions. Many insurance companies state that a pre-coverage inspection of the roof is required for a new policy or the renewal of an existing policy. Someone from the insurance company will come to the home and inspect the roof before a policy is issued. For many years commercial buildings were required to have a roof inspection as part of the insurance underwriting process. If the roof of a commercial building was in poor condition it was considered to be a high risk. If a customer got hurt due to the condition of the roof the insurance company would have to pay out a settlement. Many insurance companies are new requiring roof inspections for residential insurance policies. They want to reduce the risk of a payout and repair to the roof. These repairs can be very expensive. There are some insurance companies that will cancel your policy if your roof is in poor condition.

Many people do not pay attention to their roof unless there is an issue such as a leak. You may not have looked at your room in a long time. Every so often an insurance company will send an inspector to check out your property. This will walk around and take some pictures. If they see there is an issue with the roof they want threaten to cancel the policy. Some insurance companies will give you a chance to make any needed repairs to your roof. If the repair are not made within a certain period of time and proof is not sent to the insurance company your policy will be canceled.

To understand what your property insurance policy is going to cover and the areas that it is not going to over you need to contact your insurance agent or the insurance carrier. This information is very important. If something happens to your home you need to know what the insurance company is going to cover and what is not going to be covered under your policy. The coverage for the roof will depend on the age of it and the condition that it is in. Older roofs are a higher risk for the insurance company. The average lifespan of a roof is around 20 years. If the roof is nearing this age the insurance company will view it as a risk for replacement and may not cover it in the policy. It is essential that you know what your property insurance covers and what is not covered in the policy. While it is a good idea to read the coverage options that are listed in your policy speaking to someone will give you the best results. They will also be able to answer any questions that you may have about your coverage.

Replacing your roof or even restoring the existing roof is very expensive and will take up a lot of time. It is important to take steps to prevent the roof from becoming damaged. These preventative measures can improve the lift of your roof. There are little things you can do to extend the life of your roof. The roof should be inspected annually. This way small repairs can be made to help prevent bigger problems. You also want to remove anything that is clogging the gutter. This will help prevent backup into the home. Be sure to check the shingles if you have them and make sure they are secure.

You need to remember that property insurance is not a warranty on the home. This policy is a risk that is shared between the owner of the property and the insurance under writing company. It is in your best interest to keep your roof in good condition and have it inspected annually.
