Phoenix Roll Roofing
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, it shows the cement is wet and will 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 you want or a cold applied roofing system will work for you.

Phoenix Built-up Roof FAQ
What does "built-up roofing" mean?
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 a they are self-adhering sheets.
How do you install built-up roofing?

What are the major issues with a built-up roof?
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.

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.
Is a built-up roof the right choice for my house?
You should discuss your options with a contractor that performs both systems to give you an honest opinion on what is best for you. Do you have problems with birds, insects, and rodents? Then a built up roof would be best for you. Do you have hard to reach areas that would make installation difficult if not impossible? Then foam might be a better solution. Also, make sure to discuss the longevity expectations you have with your roof and home. These are all important factors in making the right choice for you.
