A flat roof is a type of covering for a building with a form of roof that is horizontal or nearly horizontal. In California, any roof with a pitch less then 2.5/12 is classified as a flat, near flat, or low-pitched roof and is required to be roofed with a flat-roof type application. Some of the most common types of flat-roof applications are: hot-tar-and-gravel; single-ply-rolled roofing; PVC (vinyl) membrane roofing; or torch-down roofing.

WHAT ARE THE PROBLEMS WITH FLAT ROOFS?
Flat-type roofs are notorious for roof leakage. These types of roofs are very difficult to age and are very hard to find the source of roof leaks. In fact, after a repair that was thought to have solved the problem, the roof may continue to leak again and again. Be wary of roofers or handymen who have little or no experience in solving flat-roof problems. Often times you will pay them for a repair and you will never be able to get them to follow-up on a subsequent leak.
DOES ROOF DOCTORS CERTIFY FLAT ROOFS?
No, Roof Doctors does not certify any type of Flat Roof, Near Flat Roof, or Flat-Roof Application. In fact, no reputable roofing company will certify a roof with a flat-roof type application. Usually the only company that will certify a roof with a flat-roof application is the roofing company that installed such roof. We recommend that a homeowner contact the local City or County Building Department that has jurisdiction over their home and obtain a copy of the building permit for the installation of the existing roof. The Building Permit should include the name of the roofing company who installed the existing flat-roof system. The roofing company on the Building Permit should then be contacted to see if they will still honor any existing warranty that may exist for the flat-type roof that they had installed.
In any event, if the roofing company is no longer in business or the existing roof has exceeded its warranty period, the roof may need to be replaced. Since Roof Doctors does not install new roofs; a roofing company that specializes in flat-roof installation would need to be contacted for a replacement estimate. Be careful, many of these flat roofs are installed without building permits, such as over the back patio, front porch or a converted garage.
IS THERE ANY EASY WAY TO OBTAIN A BUILDING PERMIT HISTORY REPORT ON YOUR HOME?
Yes, there is an easy way to obtain a Building Permit History Report on a home. Our friends at GeoAssurance allow you to go to their website to order a Report detailing the history of building permits that have been issued by the local building department. Go to their website HERE, fill out the form and submit a request, and you will have your report in a short period of time.
HOW DO YOU KNOW IF YOU HAVE A FLAT ROOF?
If the pitch of the roof is less than 2.5/12 then you have a near flat or flat roof. This means for every 12 feet horizontal the roof rises by less than 2.5 feet. Roof Doctors does not repair or certify flat, near flat, or flat application roofs nor do we specialize in these types of roofing. We will be happy to tell you what type of roof you have, but that may be the only information we can give you. We recommend you contact a flat roof specialist to look at your roof if you suspect it falls in one of these categories.
