How Often Should You Seal a Flat Roof?



Roof sealing is an important part of protecting your flat roofing from the elements and prolonging its life span. A good flat roof should last for 10 years. However, with the right coating, it can last even longer. Sealing your flat roof can extend its lifespan and decrease the need for repairs. How often should you seal your flat roofing?

How to Cover a Flat Roof

Water protection is the main reason for re-coating a flat roof. The roof may leak if it ponds. This can cause further damage to the interior. To avoid water damage, it is worth sealing the roof at least every five years. The following factors can influence how often roof coatings are done:

Roof Style

Regular roof sealing is essential for flat roofs as they are more susceptible to ponding. To prevent water from leaking into your building, the roof surface must be completely waterproof. To prevent water damage, even the smallest leaks must be addressed immediately. A flat roof that is not sealed can reduce its lifespan by as much as 50%. Because water is more efficient and less likely to pool, sloping roofs don’t need to be sealed as often.

Your Local Climate

Roof sealing is more important in harsher climates. The sealant can be damaged faster in harsh weather than it is in climates that don’t have intense heat, sun, or rain. High winds can also cause roof damage by tree branches or other debris. Repetition of sunshine and rain can also cause the sealant to shrink and contract rapidly, making it need to be re-applied frequently.

How to tell if a flat roof needs coating

Sealing flat roofs is important as a preventive measure. Don’t wait for leaks and ponding to happen. Roofs that show signs of leakage or structural damage need to be coated. Even if you don’t see any signs, flat roofs should be sealed every five years to protect them from water damage.
