Flat Roof Options for Your Ft. Lauderdale Home

28 Mar 2013

In Ft. Lauderdale home roofing design can be a big deal. If you’re considering residential flat roofing there are a few things you need to consider before you install the roof.

For starters, flat roofs take a beating from the sun and torrential rains so design and materials will play a big part in how long your roof will last. On the plus side, reflective flat roofs can go a long way in reducing your cooling bill. Before you give your roofing contractor the go ahead, take a quick look at your flat roof options:

  • Built-up roof (BUR). This is the traditional hot tar and gravel roof that consists of three or more layers of waterproof material with a layer of hot tar on top of each. The roof is then topped off with smooth river stone which is not only attractive but is a fire retardant as well. This is the least expensive flat roof material but it is also the heaviest. Supporting joists may have to be reinforced.
  • Modified bitumen. This is a single roll of roofing material that is impregnated with a mineral based wear surface. Its light color does an excellent job of reflecting heat making it ideal for our Florida summers. Application is either by peel and stick (preferred) or “torch down” which involves heating the adhesive as the roll is laid out. Anytime torches are used there is a potential fire hazard.
  • Rubber membrane (EPDM). This roofing material most resembles that of an inner tube. It can be anchored to the roof using fasteners, ballasted with gravel or glued down. EPDM is more scuff resistant than other materials but if there is a puncture it’s easy to repair.

While the type material that you choose will be the major factor in total cost how well the roof performs will depend on how experienced and skillful the roofing contractor is.

Flat roofs present different installation challenges than pitched roofs do. Make certain the Ft. Lauderdale home roofing contractor you choose has the experienced staff and the equipment to do the job right.
