Reliable Commercial Flat Roof Repair
Commercial flat roofing systems aren’t used as often as sloped roofing, but is becoming a lot more common. There are four main types of flat roofing. We’ll go over the pluses and minuses of them all. The cost of installing or replacing a flat roof can average around $250 to $450 per sq. ft. and they’ll typically have a warranty that ranges between 10 and 20 years. However, the flat roof itself can have a lifespan of up to 25-30 years if its maintained in a regular and proper way.
There are four main kinds of flat roofing systems:
- Modified Bitumen
Modified bitumen is made of reinforced asphalt impregnated felts. Unlike built up roofs, the asphalt in the felts is modified with plastic or rubber polymers to improve flexibility, durability and overall performance. Because of the polymers, modified bitumen can be applied in a single layer and overlapping the seams. They’re then glued to the roof with hot asphalt or an adhesive, or by using torches to melt the asphalt underneath. Some modified bitumen roofs require protective surfacing materials, usually mineral granules or a liquid coating.
- Built-up Roofs
Built-up roofing (BUR) is what is often called “hot tar roofing.” Its an old, time-tested method. Built up roofs are made of three or four overlapping layers of asphalt felts which are fused together by hot asphalt. They have to be protected from extreme weather, sunlight and people walking on it by some kind of surface material like gravel, a mineral granule top layer (a cap sheet), a coat of asphalt or a some type of special reflective coating.
- Single Ply
Single ply membranes are made of rubber, plastic or a combination of both. Single ply membrane is applied in a single layer. Installation is simple: roll out the membrane, heat weld the seams between the sheets, chemically weld them or glue them together, then the membrane is attached to the roof with screws/flat plates, ballast (like rocks) or adhesive.
- Polyurethane Foam
Foam is sprayed straight onto the roof, where it “foams up” and hardens before a protective coating is put on top. Because of its flexibility, foam is especially good for roofs with unusual shapes and configurations. Foam has several unique advantages over other types of flat roofing systems. It protects against thermal shock and it can greatly reduce your energy bills.

Flat roofs work well in the warm, dry and sometimes windy Texas weather. Flat roofing systems use less roofing area compared to pitched roofs, which can have as much as double the total area of a flat roof. They also do a great job of absorbing heat during warm days, which helps to insulate the interior of buildings as well. In warmer areas, every cooling opportunity is helpful in lowering utility expenses.
Commercial flat roofs have certain requirements and needs. Unlike sloped roofs, which rely on gravity to shed water and material, flat roofs depend on drains and rely on a water resistant membrane to protect the owner’s building. The term ‘flat’ is a little misleading — no roof is completely flat or water would pool on top of it. “Low slope” is a better description of what’s commonly called a flat roof. Flat roofs need to have at least a 1/4 inch of slope per foot (or more) so that water can flow downhill to the drains and then off the roof and down to the ground.
