Built-up roof systems are one of the oldest roofing systems used for commercial roofing construction purposes. Not only are they reliable, they’re easy to repair in the event of damage. With these roofs, we intend to provide customers extra protection and render better performance in the extreme weather conditions.
Essentially, a built-up roofing system consists of layers of roof felts that are laminated together. Bitumen, asphalt or some other roofing adhesive is used in between the layers. Emerging as a safer, durable and lightweight alternative, a lot of business owners are finding them to be an ideal choice for their office buildings. They are particularly useful for roof structures that are low-slope or flat.
Built-up roofing system are a choice you can never go wrong with because they can be designed and built to cater to a building owner’s needs. In addition, these built-up roofing systems incorporate multiple layers and offer superior protection in the event of hail or snow (for our Northern AZ commercial property owners).
With over 10 years of experience, we have the expertise needed to give your building’s built-up roof the ability to easily withstand harsh weather in Arizona.
There are many advantages that an owner enjoys when they choose to have a built-up roofing system installed on their building.
Sometimes existing roofs have to be completely removed if:
Roll roofing starts next and the adhesive is applied on top. At this point, it is important to ensure that the roofing adhesive is applied uniformly using a roofing brush between the layers of roll roofing. This adhesive is applied after an hour of the cement application. The drying time is around 2 days provided the weather is warm and dry (we can assume that it will be in most cases!). If it is possible to lift the roof and it shows the cement is wet, it will need some more time to dry.
Before you opt for your built-up roofing systems, it is important to determine whether it is a hot applied roofing system or a cold applied roofing system that will work for you.

Built-up roofing, in simple terms, means multiple layers of roofing products usually referred to as a base, ply and a cap. The base is exactly what is sounds like: the layer on the bottom creates a base. This can be a fire rated material which some building codes require. The second layer, called a ply, is an intermediate layer of an asphalt based felt. You can add one layer of ply or three layers of ply. Usually, the more layers the longer the warranty and longevity of the roof. The last layer, referred to as a cap, is a thicker layer of an asphalt-based membrane that has granules adhered to the membrane to provide a protection from the sun and other environmental factors. These layers are either adhered with hot asphalt or are self-adhering sheets.
Built-up roofing is installed in layers that are adhered based on the type of material that is being installed. It can be adhered with hot asphalt, a glue adhesive, or the membrane is a self-adhering product that requires no other product to adhere it to the roof deck.
Built-up roofs typically are grey, white or tan granules that look like 3’ wide sections that can be as long as 180’ long. They are installed in a staggered or brick layered pattern.
This depends on how many layers, size of the roof, and access to the building. You can expect to pay as little as $250 a square to $1,000 a square. For commercial buildings, it’s hard it give a budget number without taking into consideration of parapet walls and roof mounted curbs.
Built-up roofs allow you to get a fire rating for your property, they are economical for new builds, and add longevity to your roof with easy maintenance.
The layers applied are what make built-up roofing stronger than other roof types. Think of it as skin. Would you want one layer of skin or 5 layers of skin to protect you? The thinner the skin, the easier it is to bleed. The thinner your roof, the easier it is to leak.
Built-up roofing remains to be one of the best roofing systems out there. The reason it has declined in installation is due to environmental issues. Built-up roofing is an asphalt-based system and the cost of asphalt has been on the rise for years. If the system is applied with hot tar, the fumes that are off-gassed are not preferable for some installations. Another downside is insurance costs to the contractor. The risk for injury is higher with hot asphalt and torch down so you may have a hard time finding a contractor that will install a built-up roofing system that isn’t self-adhered.
If you do the minimum, you can expect 10 years before you might need to start looking at maintenance and built-up roof repair. If you install a better system with multiple layers, you could get 30 years on a well-maintained roof.
The most common repairs for built-up roofs are split seams, bubbles, and material degradation in areas where water sits. All can be repaired without replacing the roof.
