How to know if its time for flat roof replacement
Commercial and industrial structures are known for having a flat roof. Why? Because of money and safety. Building a sloped roof on a residential structure is less dangerous and isn’t as costly as it would be a on a commercial or industrial structure.
In fact, in many ways, a pitched roof a large commercial or industrial structure is almost impossible. Of course, with the technology and tools available today, it is possible if the owner of the building has the budget and a contractor willing to do the work. Although, flat roofing experts recommend against pitched or sloped roofing on a large structure due to the future issue possibilities.
Seriously though, are flat roofs really flat? No, a flat roof is not completely flat. It is common sense that water can’t drain from a flat surface, and when that flat surface is a flat roof, the trouble it could create for the structure supporting it is monumental. There is a low slope to the roof, as little as ¼ an inch and as much as half an inch per foot.
It is because of the low slope to a flat roof, there must be adequate drainage and that flat roofs are made of right roofing material is a must to provide the watertight surface needed. So, is a flat roof worth the concern and common question of “Do flat roofs always leak?”. We’ll answer that by stating that flat roofs do not ‘always’ leak, but yes, the are prone to leak.
Even with the workmanship set aside, every sloped or flat roof can have the possibility to develop a leak. With good roofing material and proper maintenance, a flat roof can last 30 years or more before any issues like leaking begin.
