What Do You Need To Know About Low-Slope Roof Membranes?

(Adco Roofing Inc.) What You Need To Know About Low-Slope Roof Membranes

There are different types of low-slope roof membranes and you should be aware of the difference between them. Understanding the materials and differences between membranes makes for more efficient maintenance and upkeep so you can get the best out of your roof.

What Do You Need To Know About Low-Slope Roof Membranes?

TPO roof membranes are usually all white and can be attached a number of ways. They can be ballasted, mechanically attached or fully adhered although the majority is mechanically attached. TPO has become more common in the industry over the last few years because of its thermoplastic properties. This membrane also has seams that are welded together to provide a mostly homogeneous membrane.
PVC membranes are similar in appearance to TPO membranes and are also usually a shade of white. They also are thermoplastic but are more pliant than TPO membranes as they conform with substrate changes more readily.
EPDM is a black synthetic rubber roof membrane and there are several methods of securing these. One method uses large stones or concrete pavers (ballast) to cover the EPDM membrane.

The ballast weight secures the above-deck roof insulation and roof membrane. If there is no ballast, then the system is mechanically attached or adhered. If you drag your foot across the membrane and it wrinkles, then the system likely is mechanically attached. An adhered system is different and will show the joints in the substrate. EPDM membranes typically are joined at the seams with two-sided adhesive tapes. If a roof system is not a single-ply roof membrane, then it is most likely a bituminous membrane. Bituminous membranes are usually built-up roof (BUR) membranes or polymer-modified bitumen membranes. They can be hot asphalt-applied or coal tar pitch membranes.

These systems are also multi-ply roof systems, constructed on the roof by a roofing crew. BUR membranes are most often surfaced with bitumen and gravel, mineral-surfaced cap sheets or a liquid-applied roof coating. Polymer-modified bitumen membranes have an unsurfaced base layer of polymer-modified bitumen membrane adhered to a substrate. The three most common application methods for polymer-modified bitumen membrane are hot (asphalt)-applied, cold (adhesives)-applied, or torch-applied. You can also choose to apply a protective aluminum coating, over the cap sheet.

Once you know the differences between the available low-slope roof membranes, you can make an informed decision about roofing maintenance and design. Just be sure to discuss everything with your roofing professional first.

How To Get The Right Roofing Contractor You Need For Your Commercial Roofing Job?

(Adco Roofing Inc.) Getting the Roofing Contractor You Need

Depending on the work you need to be done, there are a number of contractors you could choose from. There are a few things you should know before hiring one for your next project. The most important factor when looking for a contractor is to find one who is reliable and licensed to avoid financial risk and potential problems or damage to your roofing. Any contractor that performs work in the state of California, on a project that is expected to value more than $500 for combined labor and materials must have a valid CSLB license. You should always call before hiring to get verification of the license for any worker you are considering.

How To Get The Right Roofing Contractor You Need For Your Commercial Roofing Job?

Unlicensed workers pose a serious risk to both your safety and your finances. If a worker is injured while on your property and they are uninsured and unlicensed, you will be financially responsible. In addition to this, most unlicensed workers provide poorer quality work which can lead to serious damage and unnecessary expenses. You may save a few dollars in the beginning but you risk paying so much more in the end if anything goes wrong. When you carefully plan your project in advance, you can better locate and hire the most reliable and qualified contractor. Clearly define what you need to be done before deciding who is the best for the job, so you can narrow your search by relevant experience. You typically get to choose between a general and specialty contractor and understanding the difference is important to your decision.

General contractors are responsible for overseeing projects and coordinating the work of specific licensed subcontractors for any particular job. Specialty contractors, on the other hand, are hired to perform a single job or project. When you need a roofing project completed, you should look to hire a specialty roofing contractor to ensure you get someone that knows the industry best. General contractors can also contract for specialty work, but they need to hold a valid license for the specific type of work being done. The only exception to this is when the project has more than two types of work involved, and, in this case, a general contractor will oversee the combined efforts of the project. The general contractor will also hire subcontractors who have specialties based on the work that is needed.

There are many contractors out there to help you with your various installation and replacement projects. When you know the difference between general and specialty contractors you can make the best decision and in the end, the hiring process will go much easier. You will also get the best possible work done for your project.

Roofing Estimate vs. Roofing Proposal – What’s The Difference?

Adco-Roofing-Estimate-vs-Roofing-Proposal

When it comes to getting roofing installed or roofing maintenance it is important to know the difference between estimates and proposals. The two are frequently confused because they seem so similar but there are key differences you need to know.

Roofing Estimate vs. Roofing Proposal

Estimates

Estimates let you know the types of materials that will be needed for the project. It also lists out the scheduled time for the project, cleanup, and the contractor’s liabilities and warranty information for the roof. Estimates also include how the roof is to be paid for and if there will be any add-on costs. Any potential add-ons will be explained in the estimate in full. You need to be aware that some contractors will try to use the estimates as a means to get you to sign a contract, by acting as if it is a formal proposal. This is not the purpose of an estimate. Estimates help you evaluate which roofer you may want to work with. A professional and trustworthy contractor, however, will give an estimate to provide the specific details and costs that are to be involved in your roofing project.

Proposals

A roofing proposal sets the cost for a project that the contractor and building owner are bound to. Most roofers will have set costs for materials and labor and they will provide these costs in full as well as give detailed breakdowns for each component of the project. Any additional costs will also be included. Proposals give a final price that is not to be exceeded regardless of what happens during the course of the project. If this is a number you do not like, then do not enter into an agreement or contract with the roofer. Be sure to discuss every aspect of cost with the roofer so you will be aware of exactly what you will be charged for.

Not all proposals are the same and they can differ by project, contractor, and client demand. Some proposals will also be lengthy while others only one page. Beware of very short proposals, because it will likely be missing details and critical information. Your roofing is an investment, just like the building, so collect your estimates, make a decision and discuss a detailed proposal with your contractor before entering any contract.

The Biggest Mistake Building Owners Can Make

ADCO-the-biggest-mistake-building-owners-can-make

Do you own a commercial building? If you do, it was more likely an investment and likely one of your largest assets. Yet, surprisingly, many property owners neglect to be cautious when hiring a roofing contractor to protect these assets.

The Biggest Mistake Building Owners Can Make

Don’t wait

Many owners will wait until there is a significant issue or damage before reaching out to a contractor. Once a problem like water intrusion has occurred you will have to take care of painting and remodeling as well as roof replacement which is a major mismanagement of the building’s upkeep. Sadly, many property owners feel like there is no problem paying $7 to $8 per square foot for carpet installation but a roof system that costs $3 to $4 per square foot often is considered unreasonable.

More than money

When your focus is only on price, there always will be something cheaper around the corner. Plenty of roofing contractors cut corners and use cheap materials in order to extend low prices to you. When selecting a roofing contractor, you need to hire a quality roofing contractor over one who is cheapest or can start the job right away. There is usually a reason that certain contractors are available immediately, so you should always beware and do some research first.

Do research

When it comes to buying a new car or another pricey commodity you don’t just go with the cheapest and you don’t go to a no-name dealer or store. You cannot be impulsive with your investments and roofing contractors fall in the same category. We think the roof that protects your building is a big deal and protecting your investment requires working with a contractor that knows what they are doing. How long they have been in the industry, whether they are insured and licensed, and if they offer warranties are all important. Knowing what you are purchasing and from whom is essential to your overall success.

Be proactive

When you are proactive, your roof system investment is far more effective. Invest in maintenance and regular upkeep to prolong the life of your roof. Make sure gutters are clear from debris and drainage is running efficiently. See to any leaks or cracks right away before they turn into more expensive damage. A full roof system replacement should be done once or maybe even twice in a lifetime. If you plan ahead and give your roof a little attention as needed, you will make the most of your investment and get the most from your roof.

The Top 5 Things Contractors Wish Their Customers Knew About Roofing

Adco Roofing Inc.) The Top 5 Things Contractors Wish Their Customers Knew About Roofing

As a building owner, it is important to work with a roofing contractor to ensure the roofing system is well maintained. Hiring the right contractor can be a daunting task though as can purchasing a new roof system. The process of installation or maintenance requires everything from technical jargon to evaluating numerous contracts and proposals. In the same way, contractors find it challenging to work with clients that have little knowledge about roofing.

The Top 5 Things Contractors Wish Their Customers Knew About Roofing

To make the process easier for contractors and their potential clients, there a five important things that every building owner should know.

Tip #1

There is a difference between price and value and you need to understand that there will always be a contractor who will do a job for less. Cheaper pricing is not indicative of better quality. In fact, it is usually the opposite. Roofing systems are not like commodities where bargain hunting can pay off. You want to collect multiple bids and then base your decision on more than price. Carefully consider the knowledge and experience of the contractor and verify their references. When you only choose based on price, you run the risk of getting a bad product and inferior service.

Tip #2

Understand the importance of routine maintenance. When you are proactive about your roof care, your roof’s life can be extended and you make the most of your investment and resources. Roofing contractors report that they often end up replacing roofs that could have had longer lives with regularly scheduled maintenance. A little maintenance can go a long way and save you from needing a new roof or leak repairs, so find a contractor that will work with you on getting the required maintenance for your roofing system done.

Tip #3

Find a roofing contractor who is established and reputable within your local area. You want to ensure your contractor has proper licensing, carries the appropriate and valid insurance, and can perform all essential roofing installation and maintenance work. A contractor who only uses subcontractors may not have appropriate insurance or licensing and this could be a risk for you so make sure you always ask for the paperwork before hiring anybody.

Tip #4

Building owners also need to understand when their roof is beyond repair. There are many roofs that cannot be saved no matter what and putting any more money into it will be a waste. The situation can be frustrating when you make a lot of repairs and the problems still remain. Be sure to work with an experienced contractor to predict when your roof will need a replacement as this will help you budget accordingly and avoid money traps.

Tip #5

Never underestimate the value of contractors who have an active membership to the National Roofing Contractors Association. NRCA members know about industry code changes and technical issues and are fully informed regarding the best practices to ensure you are a satisfied customer. NRCA provides the resources that all contractors need to make good roofing and business decisions which mean better service for you.

How To Avoid Roof Damage Or Injury On Your Roof?

(Adco Roofing) Safety in Roofing Repairs

 

 

The roofing industry has the 6th most dangerous jobs in the country, being responsible for almost 30 deaths out of 100,000 workers each year. This is close to double the amount of deaths caused in the construction industry, which means that attention has been given lately to ensuring workplace safety for roofing projects. Reliable and professional contractors use only the safest practices which adhere to strict safety protocol. Both workers and the job at hand are important so safety is always a high priority. It is important for you to schedule regular maintenance and inspection of your roofing as a way to keep your roof in prime condition and to avoid unnecessary damage or injury. Leaks are the most common roofing problem so the need to identify and repair a leak right away is necessary. Leaks can be easily avoided by scheduling regular roof inspections.

Even if water does find a way through, you need to get the leak repaired immediately. This helps to avoid further damage to your building and a keeps your roof safe at all times. Water that enters the building through a leak can damage ceilings as well as structures. Ceiling tiles can become loose and fall, causing damage to equipment as well as injuries to people inside the building. In addition to this, water that seeps through cracks can drip onto surfaces, increasing the risk that people will slip and fall or damaging expensive materials and items.

Water that gets into the walls of a building also promotes mold growth, especially with wood and gypsum drywall. The smallest patch of mold can release very resilient spores that can spread easily through the building to other surfaces causing more extensive damage. Mold causes serious damage to building structures and has also been known to cause serious health problems in people too. When it comes to roofing, there are two important factors you need to be aware of. Firstly, the decking is an integral part of your roofing system and if it is faulty at all, it needs to be repaired immediately. Poor decking means that your roof will not last long and a roof with a short lifespan causes the building to lose value and you to lose money. Ensuring you have solid decking is the best way to ensure the longevity and quality of your roof. The second thing to remember is that waterproof materials are essential regardless of the climate you live in. You want to ensure that the roofing contractor you choose has a clear understanding and experience with waterproofing options and can advise of the most effective means of preventing pools and leaks. The main cause of leaks is poor roofing, but you can avoid this by hiring a roofer that knows how to successfully divert water away from the building.

Safety and quality are essential components of the roofing industry. It is important that you hire a qualified roofing contractor to ensure your roof stays in the best condition. A safe and reliable roof will not only protect your building, but it will protect the inhabitants and be a safer working place for contractors.

Understanding Differences Among Low-Slope Roof Membranes

Adco-Understanding-Differences-Among-Low-Slope-Roofing-Membranes

When it comes to low-slope roof membranes there are differences you should be aware of. As a building owner, it can be helpful for you to understand the characteristics of the roof membranes on your building. EPDM is the most common membrane and is a black synthetic rubber roof membrane. EPDM roof membrane can be secured in a number of ways. You can use large stones or concrete pavers, known as ballast, to cover the EPDM membrane. The weight of the ballast secures the above-deck roof insulation and roof membrane. If there is no ballast, the system mechanically adheres. A mechanically adhered system has round plates that are aligned a few inches inside the laps in the membrane.

Understanding Differences Among Low-Slope Roof Membranes

You can easily identify a mechanically adhered roof by dragging your foot across the membrane and if it wrinkles in front of the foot, it is likely mechanically attached. These systems more readily show the joints in the cover boards and will likely have plates visible beneath the membrane. EPDM membranes are also typically are joined at the seams with two-sided adhesive tapes. TPO roof membranes are usually white and can be ballasted, fully adhered, or mechanically attached. The vast majority are mechanically attached. TPO membranes have become more common over the past several years and much of this popularity has to do with being thermoplastic. This means the seams are welded together to provide a mostly homogeneous membrane. PVC membranes are similar in appearance to TPO membranes in that they are typically white. They also are thermoplastic but happen to be more pliant than TPO membranes and will conform with substrate changes more readily. If a roof system is not a single-ply roof membrane, then you likely have bituminous membrane, which is asphalt- or coal tar pitch-based. Bituminous membranes typically present as built-up roof (BUR) membranes or polymer-modified bitumen membranes. BUR membranes can be hot tar pitch membranes or constructed using “cold process” adhesives.

BUR roof systems are multi-ply roof systems that are constructed by a roofing crew. BUR membranes usually have one of three surfacings. They are either bitumen and gravel, mineral-surfaced cap sheets or a liquid-applied roof coating. The benefit of a roof coating is to provide reflectivity, ultraviolet protection, and to withstand tough weather conditions. Polymer-modified bitumen membranes usually consist of an unsurfaced base layer of polymer-modified bitumen membrane which is adhered to a substrate and a cap sheet.

The most common methods for installation of polymer-modified bitumen membrane application are hot-applied, which is using hot asphalt, cold-applied which involves using cold adhesives, or torch-applied. Cap sheets can be surfaced with minerals, granules or foil facer, or a protective coating, such as an aluminum coating, over the cap sheet can be applied. Understanding the differences between low-slope roof membranes will help you to make an informed decision when it comes to having roofing discussions with your hired contractor.

Why Should You Hire a Roofer for Your Flat Roof?

ADCO why should you hire a roofer

Maintaining the appearance and quality of a flat roof requires regular maintenance. By investing in this, you can ensure that your roof stays safe and can withstand harsh environments and weather conditions. Your roof will naturally age with time, but with regular maintenance and repairs, it will be guaranteed to last longer which protects your investment.

Hiring a Roofer for Your Flat Roof

There are a few key problems you will face with your flat roof, and hiring a roofer ensures these can be taken care of efficiently.

  • Flat roofing is susceptible to ponding. This is when water from rain or melted snow pools in areas of the roof. If this ponding is not corrected right away, it can weaken the roof materials causing leaks and structural problems. Once the exterior is compromised, you may also experience internal structural damage which can be expensive, so you need to contact a roofer as soon as you notice the ponding.
  • Over time, roofing systems can crack along the membrane. Lengthy cracks will appear spongy and are caused after periods of alternating freezing and thawing. An experienced roofer can inspect your roof after each season to identify any cracks or splits and repair them before they spread.
  • Flat roofing typically is layers of substrate and felt, and air can become trapped within these layers. When this happens, the roof can blister which makes it unstable. You can identify blisters as elevated pockets in your roof surface. Call a roofer as soon as you see this and they can remedy the situation and prevent further and more expensive damage.
  • Ridges can also occur when a bituminous buildup occurs within the joints of the roof insulation. This typically happens when moisture condenses under the felt layers. Ridges appear as long, narrow crevices and they most likely can be seen along membranes that are not securely attached.

These issues are common with flat roofing systems, but with regular inspections and maintenance, they can be avoided or repaired once identified. We recommend that you call us to inspect your roof even if you have not noticed any of these problems. With a regular check, we can prevent these problems from occurring before they cause too much damage. Preventative maintenance will be the best way to protect your roof, your building, and your investment.

Tips to Find and Fix a Leak

roof leaking

Roofing leaks are the most common roofing problem as a result of wear and tear or weather changes. Sadly, many people do not realize they have leaks until it is too late. If you notice any water damage inside the building, chances are you have a leak. Tracking the source of a leak can be challenging, so you should call a roofing contractor to help. Once you know where the leak is, repair is not as challenging.

Tips to Find and Fix a Leak

If you think you have a leak, the first place to check is any penetrations, such as vents, ducts, or dormers. These are common places for leaks to start. Check the building for water stains, mold, and black marks. If you notice these, you likely have a leak and need to contact a roofer to inspect the property and repair any damage. Some leaks can be tricky to find. A professional roofer can find these by soaking the roof with water and watching for leaks on the inside. In some cases, the drips or water appear far away from the actual leak. This is common in roofs where plastic vapor barriers are installed within the insulation. A roofer will be able to move this aside and find the smallest leaks that could be hiding from your eyes.

  • Check the vents: Plumbing vent boots can be made from plastic, metal, or both. Plastic can crack and metal seams can open, so the vent boot is a good place to start looking for any leaks. Any broken seams or cracked plastic pieces should be replaced immediately before serious leaks happen. When you are replacing the broken or cracked vent, you should replace all nails with screws as these interfere less with the roofing material.
  • Dormers: Water can leak from above the roofing, especially if the weather is severe. Cracks in windows, dormers, and siding are all possible and will allow water to reach the inside. Before calling a roofer, check the edges with a knife to identify any leaks. The caulk will need to be replaced by a roofer if any cracks are found.
  • Flashing: Most buildings have flashing installed where the walls intersect the roof. Flashing helps to move water away from the roof and with time they can rust, weaken and allow leaking. If you see any damaged or rusted flashing, it needs to be repaired immediately.

Call us today to inspect your roofing and we will help you to find any leaks. We have the experience and skills to get every leak fixed to keep your roof in optimal condition for longer.

Is Your Commercial Roof Ready For The Rainy Season?

Is Your Commercial Roof Ready for The Rainy Season

Is Your Commercial Roof Ready For The Rainy Season?

The rainy seasons can damage your commercial roofing and this damage will be worse and cost even more money if there were pre-existing cracks or tears before the weather gets here. It is important to ensure your roof is repaired and in optimal condition before the rain and snow arrive. Failing to get the roof fixed ahead of time will not only cost you more money but the damage could end up being irreparable. Commercial roofing has a flat design that puts it at greater risk for damage. Cold weather can easily make worse existing cracks and these cracks or tears increase the risk of internal damage as well. Roof repairs are not cheap, but they will definitely be more affordable when done before the rainy season. Protect the value of your building and your investment by ensuring your commercial roof is in optimal condition before the winter arrives.

Prepping For The Cold

Repairs before rain and snow damage are cheaper than a full roof replacement. During the winter, the continuous cycle of water thawing and freezing causes the most damage to your commercial roof. Existing damage to the outer material allows melted snow or rain into the roof and as the weather gets colder, this water can freeze. Water also collects on flat roofing very easily and can freeze into a lake of ice overnight. This additional weight can be too much for your roof to bear. Icy roof lakes can cause serious structural damage and the water that made its way through the cracks into the internal parts of the roof causes further cracking as it freezes and expands. Water that reaches the internal components of a roofing system also causes mold and other interior damage. Ceiling and interior repairs are costly and more challenging than repairing the flat exterior of a flat roof, so you want to ensure all repairs are complete before the weather turns cold.

To ensure that your flat commercial roofing lasts through the winter months, contact a specialized commercial roof contractor to inspect and assess the condition of your roof. We identify any weakness or damage using infrared imaging and we can restore your roof to its original condition so it is ready for whatever the winter has to offer.
