Cons:
Better For Small Buildings
Flat roofs are only considered to be stable for smaller buildings. They work well with the vast majority of commercial buildings, but in some cases, special measures will need to be taken. This usually involves changing the weight distribution of the building’s interior to create more stability.
Limited Lifespan
Flat roofs may have a shorter lifespan than pitched roofs, lasting 25 years, on average. It should be noted, however, that this aspect is balanced out by their lower cost. At LOA replacing your flat roof in Austin, is much cheaper and takes less time to complete.
More Complex Water Drainage Process
Many people hold the incorrect belief that rainwater accumulates on flat roofs. The truth is that these roofing systems come with sophisticated drainage systems. Overall, this aspect is a pro, as it prevents water from collecting on the roof. However, the drainage system may need to be inspected on occasion to ensure that it is working properly.
Membrane Shrinkage
Some materials used in flat roofing systems may experience shrinkage. This shrinkage is a result of the membrane’s vulnerability to ultraviolet radiation and can create a situation in which hail is a big hazard.
