If you live in a house with a flat roof, it requires more maintenance and care than a sloped roof. This is because a flat roof is more exposed to the elements, such as sun damage, hail, and wind, which can cause cracks, leaks, and deterioration over time. Therefore, you'll need to look for several warning signs that your flat roof has become damaged.
Why Flat Roofs Are Vulnerable
A flat roof is not entirely flat, but it has a shallow slope that allows water to drain off. However, this slope is insufficient to prevent water from pooling on the surface, especially if the drainage system is clogged or inadequate. Water can seep into the roofing material and cause rot, mold, and mildew. Water can also freeze and thaw, creating cracks and holes that let more water in.
Sun Can Be Very Damaging to Flat Roofs
The lack of shade is another factor that makes a flat roof more exposed to the elements. A flat roof receives more direct sunlight than a sloped roof, which can heat the surface and cause thermal expansion and contraction. This can weaken the roofing material and create gaps and fissures. Sunlight can also fade and degrade the color and quality of the roofing material over time.
Wind Damage Is Prevalent
A flat roof is more prone to wind damage than a sloped roof. Wind can lift up the edges of the roofing material and create tears and rips. Wind can also blow debris and dust onto the roof, scratching and damaging the surface. Wind can also cause vibrations that can loosen the fasteners and joints of the roofing material.
When Roof Repairs Are Needed
If you notice any of the following signs on your flat roof, you may need a roofer to inspect and repair it:
- Water stains
A contractor determines whether it needs a simple repair or a complete replacement. A contractor can also advise you on the best roofing material for your flat roof, such as asphalt, rubber, metal, or PVC. A contractor can also install proper drainage systems, insulation, and ventilation to prevent future problems.
A flat roof can be great if you maintain it well and protect it from the elements. However, if you neglect or ignore the signs of damage, you may incur costly repairs or replacements. Therefore, inspecting your flat roof regularly and calling a professional contractor if you notice any issues is crucial.
