Typically flat roofs are made of large, single sheets of BUR, EPDM, Modified BUR, PVC, or TPO in large sheets installed in various ways and fastened to the roof substrate by different methods. While you can’t keep a flat roof from aging or developing leaks simply because you know what type of material the roof is, being educated and informed of different types of flat roof material will help you make the best decision when it comes to repairs and replacing your current roof.
Here, we offer a brief summary of these flat roof materials:
The most common reason that a flat roof leaks is because you hired an inexperienced roofing contractor. The next reason is budget. When you combine those 2 things together, you’re going to have a leaking roof.
Another cause of a leaking flat roof is having the wrong type of material on the roof. A flat roof with EPDM material cannot be repaired using roofing tar. An inexperienced roofing contractor will likely try this because they don’t know how to work with EPDM roofing.
A third reason a flat roof is likely to leak, again, relate this to an inexperienced roofing contractor and a tight budget: Lack of roof flashing. Flashing is a must around roof protrusions and roof transitions on commercial and residential roofing. Without flashing, a flat roof is prone to leak. The roof protrusions we’re talking about are:
Perhaps the biggest leak cause for a flat roof is poor drainage. A flat roof has some slant or slope, it is engineeringly required. It also needs drainage and if that drainage isn’t sufficient or becomes clogged, then the water will pond and seep into the membrane. From there, a leaking flat roof is just a matter of time.
This also relates to a flat roof with an overhang, because without that overhang, while a professionally installed flat roof material will encourage water to flow toward the drain, the overhang assist and assures this happens.
Flat roofing experts tell us that a professionally installed and maintained flat roof can have a life expectancy up to 40 years. The different materials and what type of climate can affect this time frame, and most important is the maintenance and upkeep of the flat roof. The more regimented the maintenance and upkeep, the longer a flat roof will last. Call (512) 660-4859 today for your flat roofing needs in Georgetown, TX.
