3-Examples of Flat Roofs Systems:

Flat roofs usually come with a 10 to 20-year warranty but the roofs can last 25 years if properly installed and with regular scheduled maintenance performed by MHEC.

1. Built-Up Roof (BUR)

The traditional hot-tar-and-gravel roof is built from three or more plies of waterproof material alternated with hot tar and ballasted by a layer of smooth river stone. Once made of tar paper, these types of roofs gradually are using more-advanced materials such as fiberglass membranes

Pros: Gravel is an excellent fire retardant; attractive for windows and decks that overlook the roof. It’s the cheapest of the four roof varieties.

Cons: Very heavy. Joists sometimes have to be strengthened; smelly and messy to install. Installation’s not recommended for occupied homes. It’s not a DIY installation job, and it is hard to find the source of leaks. Gravel can clog gutters and scuppers.


2. Modified Bitumen
A single-ply rolled roof similar to ice-and-water shield, but impregnated with a mineral-based wear surface. Torch-down systems involve heating the adhesive as the material is unrolled. Newer peel-and-stick systems are safer and easier.

Roofing membranes and synthetic rubber roofing compounds for flat roofs outperform gravel roofing materials and make roof leak detection far easier. These roofing materials are basically seamless and fight UV damage. Used mostly commercially, flat roof membranes have many residential uses.

The use of synthetic membranes has just about eliminated the need for gravel on roofs. Why? Because many of these new roof membranes are glued down to the roof sheathing. Not only that the new membranes contains materials that resist UV degradation.

Modified Roof Systems – 1 of Many Examples Used:

Flintlastic SA or Flintlastic SA FR
The Flintlastic SA products can be used in various system configurations, depending upon the roof requirements. For small projects such as decks, additions and porches, two-ply systems comprised of Flintlastic SA Base and Flintlastic SA Cap sheet may be appropriate (in conjunction with FlintFlash™ SA flashing membrane as specified by CertainTeed). For larger roofs and commercial applications, three-ply systems comprised of Flintlastic SA Base covered with Mid Ply and Cap are recommended.

Roofs and decks must have proper drainage. The advantages of self-adhering membrane are ease of application, minimum of installation tools or equipment needed cleanliness, and the fact that no hot asphalt or torches are required for installation.

Pros: Peel-and-stick material comes in light-colored mineral surface reflects heat and cuts energy bills. Its price is in the middle of the pack.

Cons: Torch-down application is a fire 0.3t7xhazard. It’s not as scuff-or tear-resistant as rubber-membrane roofs.


3. Rubber Membrane
EPDM (short for ethylene propylene diene monomer) is a true rubber. The durable material resembles an inner tube, but it’s engineered to resist damage from sunlight. EPDM can be mechanically anchored with fasteners, ballasted with stone, or glued.

Pros: The material’s relatively light yet highly resistant to scuffs and tears. Leaks are easy to patch.

Cons: The standard black material absorbs heat, and light-colored coatings (recommended in warm climates) add 30% or more to the cost. Even the black version, though, costs more than BUR or modified bitumen. It’s also more vulnerable to punctures than other choices.
