Part 3: Getting a Flat Roof: What You Need to Know
Project Planning

Does your roofing contractor specialize in installing flat roofs? Proper installation is integral to making sure your flat roof functions as it should. This will also ensure you’re meeting manufacturer requirements so as not to void warranty coverage for your new flat roof.


Installation Considerations for Flat Roofing

Make sure you’re ready for commercial flat roofing by taking note of the following considerations:

Does your roofing contractor specialize in installing flat roofs? Proper installation is integral to making sure your flat roof functions as it should. This will also ensure you’re meeting manufacturer requirements so as not to void warranty coverage for your new flat roof.
Should you do a tear-off or roof-over?It is important to determine whether you should tear off your old roof completely or have a new roof installed over the old one as this will dictate the extent of your roofing project. If you have an old BUR or modified bitumen roof, for example, a tear-off may be needed. Check with your local roofing contractor to see what needs to be done exactly.
Does your roof deck meet requirements needed by flat roofing materials? If you’re opting for BUR or a modified bitumen roof, for instance, you should have a steel, wood, concrete or lightweight insulating concrete deck. The Asphalt Roofing Manufacturers Association also recommends that all decks for BURs or modified bitumen roofs should generally be dry, clean, and securely fastened without abrupt level changes beyond one-eighth of an inch. Don’t forget to factor in local code requirements, which you can easily address by working with a reputable roofing contractor from your area.
What kind of installation method will be used? Single-ply roofing membranes, for instance, may be fully adhered or mechanically attached. Full adhesion means the flat roofing membrane will be glued directly to the roof deck or insulation while mechanical attachment consists of fastening the membrane with screws and barbed plates unto the deck.
Will you need additional structural support? If you’re set on getting a BUR, check with your roofing contractor if you’ll need to strengthen joists. BUR is heavier than other flat roofing options so it may need structural reinforcement to accommodate its weight. If you don’t want the additional work, you’re going to have to choose another flat roof.

Take these considerations to heart to address installation concerns and soon, you’ll be on your way to making the most out of flat roofing.
