HVAC Units on Flat Roofs: The Pros and Cons


Flat roofing is ideal because it offers additional space to those buildings with little interior storage and space. The flat surfacing can store heavier equipment such as your HVAC unit when ground space is limited. While you can put many things up on your roof surface, HVAC units are the most commonly placed item on flat roof structures. There are pros and cons to having the HVAC unit on your roof.

HVAC Units on Flat Roofs: The Pros and Cons

One of the most important benefits to having your HVAC unit on the roof is that the unit will not be an obstruction for your customers or clients. It also keeps any loud sounds the unit makes away from the public. During the colder seasons, these units can turn on and off frequently, but when the noise is on the roof, it will not be a noise problem for your customers or workers. When HVAC units are on the ground floor, that means maintenance and upkeep are also performed on the ground too, which can cause major obstructions and disturbances. When stored on the roof, maintenance crews can repair the unit without getting in anyone’s way. HVAC units create a large amount of condensation which frequently needs to be drained. When it is on the ground, it can leak and cause potential accidents as well as an unsightly mess. Units on the roof do not have this problem, because any condensation can flow into the gutters and away from the roof.

The weight of the HVAC unit can cause damage to your roofing membrane. In addition to this, if you have foot traffic around the unit, there will be additional wear and tear. During routine maintenance and installation, the membrane becomes damaged which may lead to leaks inside the building. When installing an HVAC unit of the roof always ensure it is done properly because if it is done in a hurry, you can end up with low spots which can lead to pooling. If there is pooling around the unit that is allowed to sit for days, the interior material of your roof can begin to deteriorate. When the unit is on the roof and out of sight, it can be easy to forget about its upkeep and maintenance. The condensation line from the unit can cause malfunctions if not checked regularly. Puddles can form across your roof and pooling water can cause mold and rot as well as leaks.

Understanding the pros and cons of having your HVAC unit on the roof is essential so you can make the best decision for your building. While it is more practical to have these units on the roof, you must not forget that it is up there. With regular attention and maintenance, your rooftop HVAC unit and your roof will be just fine, and you won’t have any obstructions on your property.

Are Metal Roofs Worth the Investment?


When it comes to your roofing, you cannot go bargain hunting or looking for the cheapest option. Roofing is an investment just as your building is, and it can either add or subtract value from your place. The cheapest jobs may not be the best quality. To get the best in roofing you should be prepared to pay a little more and to do some shopping for the best materials and most qualified and experienced contractors.

Are Metal Roofs Worth the Investment?

Steel shingles are not a cheap option but there are versions that are more affordable. Corrugated steel shingles are the cheapest metal roofing option but they are very thin. They also need to be installed with screws which require regular tightening and re-tightening and this can be cumbersome. Asphalt shingles are the cheapest non-metal option but they require frequent replacement which can add up in overall roofing costs. The benefit of a metal roof is that it will last longer, so long as you get the right quality materials. On average metal roofing can last up to 50 years when the installation is done properly and maintenance is kept up. Asphalt shingles require maintenance more frequently and individual shingles will need to be replaced all the time. With less frequent repairs and replacement, metal roofing is a much better investment in the long term.

Is it worth investing in a metal roof if you do not plan on living there for long? This is a common problem for building owners and the answer is yes. Even if you move out long before the lifespan of the metal roof is up, the value of that roof to the building can be recouped in the sale price you ask for. Metal roofing adds additional benefit to the overall building value. If your buyers need convincing, simply remind them that metal roofing is reflective which allows for savings on energy costs. While it is true that metal roofing will cost you more upfront, the savings will become crystal clear down the road. Your energy usage will be lower, utility bills will be lower, and you won’t have to worry about roof replacements for a long time, if ever. Other roofing materials require more frequent upkeep and replacement. If the installation is done right the first time, a metal roof will take care of you for much longer.

Investing in metal roofing may seem different, but we assure you it is worth the investment. Reach out to us today to discuss your metal roofing options.

Immigration Laws and the Roofing Industry in 2019

(Adco) Immigration Laws and the Roofing Industry in 2019


This year promises to bring changes to the roofing industry both good and bad. Currently, there is uncertainty regarding immigration policies which is sure to impact labor and the roofing industry. With more than half of the trade filled by workers of Hispanic origin, there is currently a labor shortage for roofing companies across the country. Thankfully, there could be good news on the horizon.

Immigration Laws and the Roofing Industry in 2019

It is possible that current attempts to tackle and change immigration laws could give the roofing industry much needed change for the better. Close to 20 percent of the recent loss in roofing business is a direct result of these worker shortages. Since all current attempts to slow illegal immigration have been successful, there continues to be a shortage of roofing labor. All that is needed is a sensible immigration reform which would make it possible to remedy these problems for the industry. If the labor shortage was to be corrected, the roofing industry could stand a chance of recouping the loss of recent business. The roofing industry along with many trade professions has been hit so hard by current immigration laws and as the government continues to argue between the need for additional workers and the demand for secure borders, the solution may seem too far off. We are hoping for a positive immigration reform that will resolve the labor shortage challenges currently facing the industry.

Final Thoughts

Recent developments to make roofing installation easier have been started and the industry has made efforts to certify workers and increase the prestige of working in these trade professions in an attempt to boost the workforce. These are great steps forward, but there is still much loss to the industry’s success without workers. Despite these additional efforts being made to improve things in the meantime, only immigration reforms will bring a real solution.

How The Weather Will Affect Roofing in 2019

ADCO How the weather will affect roofing

Weather is challenging to predict in general but with recent climate changes, predicting the weather this year is proving to be the most challenging yet. Because roofing is a necessary part of weather protection, this unpredictability will impact the roofing industry. As natural disasters continue to happen as a result of the changing climate, certain trade professions like roofing will be impacted.

How The Weather Will Affect Roofing in 2019

Construction and roofing are influenced by weather in several ways. Roofing systems must be able to withstand any weather and typically the weather in a certain area is relatively stable. With the changing climate and unpredictable nature of weather today, roofing could be in for more challenges than ever before. With areas experiencing different weather from normal materials and roofing systems need to be changed.

Roofing is the best defense against the elements so it needs to be up to the challenge of any possible weather. With any and all weather now being possible at any given time, roofing systems need to be changed to meet this need. Typically roofers have the advantage of knowing the local area and the weather, so can accurately provide the best materials and systems. But there is no way to know what roofing should be installed when you have no idea what weather will be on the horizon.

If weather is unpredictable it can be a challenge to determine what roofing systems will be needed. Erratic weather patterns make it difficult to know what an area will face and many roofing systems will be unprepared. Customers will want materials that are durable and able to withstand any weather just in case, which is why we are proud to offer the best and newest technologies in roofing to ensure your roof stands up to any unpredictable weather conditions.

The History of Roofing


As long as mankind has needed shelter, roofing has been around. Sleeping outside in the elements is not something anybody wants, so coverage has long been a necessity. Caves initially provided shelter for the first humans but because of the dark and damp environment they created, alternatives were sought. Plus, you sometimes ended up sharing the cave with the local wildlife. Mammoth skins were discovered as a source of roofing as far back as 40,000 BC, and this officially marked the beginning of roofing history.

The History of Roofing

Natural materials like sod or animal hide served as ideal options for roofing materials. Natural materials have been used for roofing for much longer than the tiles (which are used today) have been used. China was the first place to develop and use glass tile roofing close to 5,000 years ago and today much of the country’s architecture still employs that same style of roofing and materials. While more modern materials have taken over in terms of popularity, glass tiles are still used for special buildings such as palaces and temples. While China was developing glass tiles, the Greeks were using flat ceramic tiles for roofing. Similar tiles or shingles were created by the Romans and were then brought to England in 100 BC and were used for centuries. These ceramic tiles were most commonly used in roofing for wealthier areas across Europe.

Since the creation of straw huts, thatched roofing has been a key part of architectural and roofing design. Ancient nomadic tribes used bundles of wood for roofing when it became difficult to find animal hides. The concept of straw thatching became popular and because if its effectiveness, it was used through the coming ages on many structures. Thatched roofing has always been and continues to be a low-cost option. Over the last 200 years, more modern materials have been developed and are used for roofing projects. As we move forward, the move is towards eco-friendly materials as the environment and energy conservation are of increasing importance. Roofing today is for so much more than just protection and designs incorporate ways to save money at the same time as ensuring the building is aesthetically pleasing.

Considering that the roofing profession started with stretched animal hides over poles and stones, major advances have been made in the roofing industry. As we move towards the future, more innovative and technologically-advanced methods and materials will be discovered, taking roofing to the next level.

Why Should You Put Your A/C Unit on the Roof?

Why You Should Put Your AC Unit on the Roof

Keeping cool is essential no matter where you live. We know summer isn’t around the corner just yet, but before we know it, it’s time to turn down the thermostat. Warmer summer months can be uncomfortable inside any building, so a good A/C unit is a necessity. The most commonly reported problem with A/C units are that they are bulky and often noisy. Your options for A/C unit storage are on the ground or on the roof and both locations come with benefits and drawbacks. Ground A/C units are not easy to remove once installed so be sure about this location before installation. Many commercial and industrial lots have ground options so this will likely not cause complaints. However, if your building is the only one with ground units, you may get some resistance from your neighbors that do not have a similar setup.

To avoid any conflicts, many A/C units can be installed on the roof which keeps them out of the way. This also exposes them to more severe weather changes and potential damages that could be more frequent. The winds are higher on rooftops which can knock pieces loose and blow dirt into the unit causing problems. However, a ground unit can also get clogged with debris so you face the same obstacle.

The weather in your local area will largely determine the lifespan of your air conditioning unit. With proper installation and maintenance, you can get the most years out of it no matter what the weather does. Putting the unit under or close to a tree can add some protection from the sun which will help prolong its life too. The benefits to ground units are that they are typically getting the shade from the building. One of the major problems with rooftop A/C units is remembering it is up there. Set reminders to regularly scheduled maintenance for your rooftop unit so it does not get neglected. Getting to the unit can be more challenging than ground units so you need to make sure you have the right equipment to reach and work on the roof safely. Ideally, you want to hire and work with a professional for all maintenance and repairs.

Despite the challenges of a rooftop unit, the biggest benefit is that you will have plenty of space and the unit will be out of the way. Having the unit on the roof also keeps the outdoor environment quieter and serves as better protection for the unit because sadly, A/C unit theft is more common than people realize. Rooftop installation for A/C units is more economical despite the small challenges. Work with a professional to ensure the unit is secure, regularly maintained, and it will keep you cool whenever you need.

Commercial Roofing: TPO vs. Modified Bitumen


TPO and modified bitumen are the most common types of commercial roofing systems. Modified bitumen roofing has been around since the 1970’s and TPO was developed later in the 1990’s. They are both great systems for hot and dry weather and as with all options, they both have advantages and disadvantages.

Modified Bitumen Roofing

Modified bitumen has been the go-to for commercial roofing for some time because they are practical and lower in cost. This option served as an upgrade to traditional asphalt roofing and offered enhanced longevity and flexibility. Many contractors, however, have stopped offering these systems because of the disadvantages that have recently been discovered.
Modified bitumen roofing was improved by adding substances like APP (atactic polypropylene), as a way to ensure the new systems could resist UV light, oxidation, cracking, and blistering. Unfortunately, several manufacturers have been found to skimp on the amount of APP which means the modified bitumen roofing produced is not able to stand up to the current challenges roofing faces. The granulated surface of modified bitumen was also added to provide additional UV resistance, but only this surface only makes it more difficult to identify cracks and leaks. These roofs also come with a serious fire hazard should any open flames be present during installation.

TPO Flat Roofing

Thermoplastic Polyolefin (TPO) roofing is widely considered to be the next best thing in large-scale roofing. It can be installed in one of three ways; ballasted, fully adhered, or mechanically fastened. It is a popular commercial roofing option because of the numerous benefits it provides for building owners.  The single-ply membrane is tough and tear resistant and stands up against chemical and grease spills, which are common with commercial roofing. They are also UV-resistant and fully recyclable which is popular benefit in today’s greener world. There are also no plasticizers in the insulation which only adds to its environmentally-friendly appeal.

You can apply TPO over existing metal or bitumen roofing so long as your current system is secure. This saves you time and money because you will not have to tear off and dispose of old roofing. TPO can be reheated which means you can weld seams when needed. They have a smoother surface than the granulated surface of bitumen roofing, which makes them easier to clean. TPO membranes are typically much thicker than other roofing options, which better protects your roof from falling debris and tears. Installation needs to be done properly as most problems identified with TPO have been related to poor installation, specifically seams not being welded properly. When you work with an experienced roofer, you can be assured that your TPO roofing will be installed correctly and will last longer than expected.


Whatever roofing system you decide to go with, we have the knowledge and resources to get your next roof installed with precision and quality. TPO may be the preferred option but we can discuss all options with you and we are here to answer any of your concerns regarding your next roofing project.

13 Reasons Why Rooftops Are The Best

1.Those views. Standing on a rooftop means you can see for actual miles.

2. Height gains. Especially important for short people who don’t know what it’s like to see over the heads of others…


3. Loads of cool space-saving stuff happens on rooftops in big, built up cities because there’s nowhere left on ground level. We’re talking vegetable gardens, beekeeping, and most importantly, bars.

4. You can probably see your house or workplace and it’ll make you feel like you’re in some super mega realistic Google Map.

5. Sunsets and sunrises will never look better than from the top of a roof.


6. If you have to climb a load of stairs to get up there, there’ll be some kind of view-based reward and you can tell yourself that you don’t have to go to the gym for another week.

7. The greatest movie scenes were filmed on the top of roofs; just look at Mary Poppins’ chimney sweep dance, King Kong’s accidental hostage situation and The Hangover’s pre-s@#$-hitting-the-fan Jager shots.


8. Extra special rooftops have extra special things on them, like tennis courts and movie theaters.

9. They’re the perfect spot for first dates because if you run out of chat, you can just spout on about the views until they tell you to shut up/kiss you to make you stop/run away.

10. It’s like being given a telescope over the city. You’ll spot buildings you want to visit, green spaces you want to roll around in and other rooftops you want to love life from.

11. The higher you are, the more cool points you’ll earn. “We had to climb one flight of stairs” wows no-one, but five is impressive.

12. The Beatles played their last ever gig on the rooftop of Apple headquarters in London in 1969.

13. Some rooftops have yoga classes on them which is the most zen thing ever.

Clarifying Some Misconceptions About Weather And Roofing

weather and roofing

By Dmitri Triphon

While many articles deal with misconceptions that persist regarding roofing contractors, the industry or materials, one of the biggest misconceptions relates to the weather.  I will try to shed light on some of the most common misconceptions I have heard.

1. “My roof is not going to survive the next winter; the rainy season will destroy it.”

In reality, during the rainy season, you see the results of the destruction that occurs during the summer.  Most roofing systems consist of asphalt – saturated material and ultraviolet rays of the sun destroy the waterproofing components of asphalt, leaving your roofing system without its waterproofing capabilities. This is true even for tile roofs because their main waterproofing component is an asphalt – saturated underlayment.  We live in a region where the temperature variations between day and night are exacerbated during the summer months. These variations lead to expansion and contraction of roof systems.  Once your roof has lost its flexibility, or if it was not designed to have great flexibility, to begin with, splits and cracks will start to occur.

By the time winter arrives, you will start to experience the results of this summer destruction.  Emergency leak repairs, interior damage, and long-term structural damage are all well-known to us and are associated with that dreadful feeling we get when we hear the raindrops falling on our roofs.  Most of these problems can be eliminated if you do an annual roof inspection in April or May and correct the damage during the summer or fall.

A good roofing contractor should be able to point out the existing and potential problems within your roofing system, so corrective measures can be taken.

2. “The rainy season is probably the busiest time of year for roofing contractors.”

This is another misconception.  The really busy roofing season starts in June and goes into November.  That is when the well-thought-out and well-organized roofing projects take place.  During the rainy season, we are busy taking care of homeowners associations that for some reason or another got left with leaking roofs.  A good roofing contractor is always busy.  A well-organized roofing contractor is always busy but has time to take care of his customers.

Removal of existing roofs – particularly on larger and more complicated projects – becomes a crapshoot.  The somewhat reliable weather forecast covers only three to five days.  All repairs of moisture-saturated roofs become temporary and need a second visit once the roofing system is completely dry.  Overlay over existing roofs has a danger of trapping moisture from damp morning fog, and as a result, has a shorter life expectancy.

In short, the winter is not the best time to attend to your roofing problems.  Plan to have roof repairs performed during the summer months.  Or the early fall.

I hope this article answers some questions about the relationships between your roofing system, the weather and the seasons of the year.  But more importantly it should provide some helpful ideas about organizing your roofing projects, so you are not spending a fortune for questionable winter repairs and finding yourself at a financial disadvantage in the summer when most projects should take place.

5 Signs It’s Time To Get A New Roof


If you’ve seen advertisements for roofing services in the mail, you may be wondering if it’s time for your roof to get redone. If your roof isn’t obviously leaking, it can be hard to tell whether you need to redo it, or whether you can save some money by simply getting repairs done as necessary. Here are a few things to consider before you call up a roofer.

How old is the roof?

A roof should last between 20 and 25 years. If a new roof was installed on top of an old roof, it’ll probably have a shorter lifespan than on a fresh foundation. If your roof is relatively new, you can probably just get repairs done as needed, but if it is between 20 and 25, you should probably just get a new roof.

What is the condition of the shingles?

You can tell a lot about a roof from how the shingles themselves look. Of course, you probably know if the shingles are falling off in chunks or missing entirely in places, your roof is past it’s prime, but there are a few other things to look at too.

If the shingles are curling or fraying, call a GAF certified roofing contractors as soon as possible because it’s a clear sign that the roof needs to be fully replaced. I say GAF because they have the highest quality shingles in the USA.

Shingle granules in the gutters

When you clean out the gutters, did you notice tiny pieces of your shingles in there? If you’re finding large amounts of these in the gutter, even if your roof isn’t leaking yet, you need to replace your roof soon. When lots of these are coming off the roof, it’s a classic sign that your roof is coming to the end of its useful lifespan.

The roof feels spongy when you walk on it

If you get up on the roof and it feels squishy when you walk around, it’s a sign that moisture is getting down to the decking underneath the shingles. This is a significant sign that your roof needs repairs and probably a total replacement.

You can see daylight when you go in the attic

If you can see light shining through the roof boards, this is a sure sign that your roofing needs replaced. Call a roofer immediately if this sign occurs. If light can get through, so can water, and water damage can cause significant problems to the integrity of your home.


If you’re not sure whether your roof needs replaced or not, you can always call a roofer and ask them to do an inspection. A roofing inspection can save you money if the roof doesn’t need to be replaced. If it does need to be replaced, knowing before there is significant structural damage can help you avoid having to do repairs beyond just the roof itself.


It never hurts to call and ask for more information. Most roofers are happy to listen to your concerns and help address whether or not you can use one of their roofing services to protect your home from damage.
