My house has a flat roof. What is the best roof system for a flat roof?
A. There is no one roof system that is best for all applications. Keep in mind that even if you are using the best materials, your roof system still can be installed improperly and you could end up with a leaky roof. Good workmanship and proper attention to detail (e.g., flashing and drainage issues) are just as important as material selection. Also, maintenance plays an important role in roof system integrity and service life. To assist you in your decision-making, homeowners should be informed of what is available. Please refer to the Roof System Types page to learn about the different low-slope roof systems. Also, keep in mind low-slope roofing materials manufacturers may not offer material warranties to homeowners. The only warranty you most likely will be able to obtain is from the contractor. So it is critical you work with a professional roofing contractor and get a detailed, thorough proposal. Be sure to read the recommendations listed in A Homeowners Guide to Buying a New Roof
