Flat roofs, also called low-slope roofs, are commonly found on commercial buildings where the roof space is used as a living space or roof. A flat roof has a roof pitch that is below 1.5 degrees. Most flat roofs are made of concrete and are usually used in places with warmer climates, as it is effective in keeping out the heat of the sun.
Flat roofs have many benefits. For one, they are less expensive to install compared to sloped or pitched roofs. They also provide more usable space, as they can be converted to a family deck or a patio for outdoor entertaining. Flat roofs are also more accessible than sloped ones.
Flat roofs, however, do present some problems of its own. If you are contemplating having a flat roof for your home, do take note of the following common problems of a flat roof.
A flat roof requires more maintenance than a pitched roof.
Since a flat roof is not sloped, it does not drain efficiently, and the roof can easily accumulate water. Puddles of water on the surface can seep into the roof through the seams and can cause structural damage. This moisture can also lead to development of mold and fungus. Regular check-ups and cleaning of the roof are necessary to make sure it is free of water and any debris.
Cracks can develop in your flat roof.
Flat roofs usually have more pressure on them, making them prone to cracking. Once your roof cracks, it is a sign that your roof is structurally compromised and that you must call a roofing expert immediately.
Flat roofs have shorter lifespan.
Flat roofs typically do not last longer as sloped or pitched roofs. The lifespan of your roof is affected by the maintenance measures done on the roof, as well as the materials that were used. Talk to your roofing professional to use the most durable materials for your flat roof.
Blistering or Alligatoring of the roof.
Alligatoring is the event where the roofing membrane grows some bubbles and resembles the skin of an alligator. This happens when the asphalt used on your roof has aged, causing it to crack and form bubbles. When this happens, call your roofing professional for roof replacement.
Flashing problems can occur in your flat roof.
Like other materials, your asphalt roofs will expand and contract with changing temperatures. This continued expansions and contractions can cause the flashing to separate from the edges of your roof. This can lead to leakage, with moisture getting trapped inside your roof.
Like any other parts of your home, your roof also needs proper and regular maintenance, regardless of the roof type that you have. To ensure that your roof is in good hands, call a roofing expert to help you. Your roof not only protects your home and properties, but it also protects you and your family. Give it the care and protection that it needs so it can protect you better for a long period of time.
