The lifespan of such a roof depends on several factors, primarily on the quality of the materials you use. For the highest quality asphalt shingles, the lifespan can be up to fifty years. You can expect a composite asphalt tile roof to last between fifteen and forty years. As skilled commercial roofers, one of the most common questions we hear is: “How long does a flat roof last? That answer depends entirely on the type of roof.
From EPDM to metal roofing, at Pequea Valley Exteriors we take care of everything. Learn about the lifespan of your flat roof and discover our restoration solution that adds decades to almost any roof. This flat membrane roof style was designed to provide a white surface that reflects the sun's rays and thus reduces energy bills. After years of cooking under the hot sun, the only TPO roof membrane becomes brittle and cracks.
These fractures in the roof surface allow massive water infiltration through the roof surface and are the main factor limiting the lifespan of this flat roof. Built with metal panels rather than having a rubber surface, these roofs often have a longer lifespan thanks to the durable quality of roofing steel. Like EPDM roofs, R-panel roof joints are vulnerable to water infiltration. While metal panels tend to be very water resistant, water can still find a way to undermine what could be a much longer lifespan.
Flat roofs still have a slight slope because water would accumulate on the roof and cause endless problems if they didn't. In general, if properly maintained, flat roofs have a good life expectancy, but this varies depending on the type of material used. You can help extend the life of your wooden roof by making sure it's free of moss and immediately replacing cracked or broken roof tiles. Like slate roofs, the building structure and roof must be strong enough to support the weight of roof tiles.
Usually used on flat roofs or only have the smallest slope, constructed roofs are made with alternating layers of roofing felt and waterproof materials. Metal roofs with vertical joints are also highly resistant to extreme weather conditions, such as strong winds, hail, snow and heavy rain. Whether it's made of asphalt, metal, rubber, or other materials, the longevity of a flat roof depends on many factors. Due to the quality and durability of these materials and the fact that a trained professional must install them, this roofing material is more expensive than other available options, at least in advance. Major roofing work is one of the biggest capital expenses involved in owning a building and that's why the lifespan of flat roofs is so important.
The type of roof is the main factor that determines how long a flat roof will last if not installed properly, of course. Replacing a flat roof can prevent serious problems, such as water damage, mold formation, and structural deterioration. For this reason, people don't often use rolled asphalt roofs in homes or other occupied structures. One of the most critical aspects of maintaining a flat roof is identifying when it's time to replace it.
Slate roofs can last a hundred years or more; this is demonstrated by the fact that slate roofs were still installed hundreds of years ago.
