Flat Roof Repairs
Commercial Flat Roof Repair and Replacement Services
Flat roofs maximize a tenant’s ability to use all space above and below the roof, making them cost-efficient and practical. This style of roof is common in cases where tenants of a building need to be able to access the roof on an ongoing basis for various reasons such as maintenance, frequent building inspections or recreational use. Some common uses of flat roofs include helipads, outdoor restaurant/bar seating and recreational and sport areas such as tennis courts, swimming pools and lounges.
Commercial Flat Roof Repair and Replacement Services
Despite the many benefits and uses of flat roofs, this type of roofing system has a relatively short lifespan (usually around 10 years) and requires regular maintenance to ensure its safety and functionality. The most common problem associated with flat roofs is leaking. Leaks can be caused by environmental factors such as UV rays or extreme weather, out-dated roofing technology or improper installation, rooftop equipment installed by unqualified contractors, and standing water on the roofing surface. Any of these occurrences can and will lead to problems that can be costly if not caught in time. For this reason, it is recommended to have a professional perform a roof inspection twice a year, as well as after major storms.
What Type of Flat Roof Repair & Maintenance Is Needed?
Keeping roof drains free of debris is an important and often neglected maintenance item. In fact, it is perhaps one of the most important flat roof maintenance items, since its neglect could lead to an array of serious problems that would require repairs. If a roof drain becomes clogged, water will pond on the roof. Ponding water is extremely problematic as it can seep into flashing seams and freeze, weakening the seams. Because 90% of all flat roof leaks occur at the flashings, repairs to the lap seams in the base flashings often need to be made.


In general, any ponding that occurs on a flat roof adds additional weight to a building that may not be engineered to accommodate it. While ponding water is the major perpetrator of leaks in flat roofing systems, improper workmanship during initial installation can lead to a lack of proper ventilation, open membrane seams and empty pitch pockets, all of which allow moisture to penetrate the roof. Even small amounts of trapped moisture on a flat roof can lead to blistering, warping, internal leakage, growth of moss or silt, and roof rot.
