The best way to shop for flat roof installation materials is through a professional installer like JB Roofing and Construction. We have direct connections with manufacturers and stay up to date about the availability of new projects.

Local home improvement retailers generally have very limited selections of modified bitumen flat roof membranes or asphalt coated rolls for your flat roof installations. As a result, it is best to consult with a professional who can assist you with your decision and inform you about your full range of options based on a climate zone, typical weather conditions, flat roof installation type and building codes.

The cost of your flat roof installation project will depend on a range of factors, but the total expenses usually hinge on the price per square foot of the flat roof materials you choose and the labor costs of completing the flat roof installation.

If you are concerned about the total cost of your flat roof installation, contact JB Roofing and Construction and we will put together an itemized estimate that will reflect all charges and fees associated with your flat roof installation. We can perform an inspection of your existing roof, obtain detailed measurements, help determine the roofing material that your flat roof installation will require, and assess the complexity of your flat roof installation project.


The price of most flat roof installation materials is generally less expensive than the materials typically required in sloped roof projects like slate, metal or cedar shingles. But, like any roofing project you will also need to consider other essential materials necessary to complete your flat roof installation such as roof flashing, underlayment insulation, fasteners, and adhesives.

Additionally, roof design, the type of materials used, and overall complexity will impact the labor costs involved in your flat roof installation. For example, the installation of a flat roof that uses the torch down installation method will have a higher labor cost per square foot than a cold or self-adhesive flat roof installation process. Further, if your flat roof installation project has multiple skylights or other roofing obstacles this will also increase your total cost.
