Roof sealing is a vital part of protecting your flat roof from the elements and extending its lifespan. Generally, a good quality flat roof is expected to last about 10 years, but with proper coating, it can last much longer. Sealing is a great way to extend the lifespan of your flat roof and reduce the number of repairs it may need. But, how often should you seal your flat roof?
When to Coat a Flat Roof
The main reason to recoat a flat roof is for water protection. If ponding does occur, the roof can leak and cause more damage inside. It’s worth resealing the roof every five years or so to avoid water damage. However, the following factors may often influence the frequency of roof coating:
For flat roofs, regular roof sealing is absolutely crucial since they are at high risk of ponding. So, the surface has to be perfectly waterproof to prevent leakage of water into your building. Even the smallest of leaks should be dealt with promptly to prevent any water damage. Typically, a flat roof left unsealed can have its lifespan reduced by up to 50 percent. Sloped roofs, on the other hand, do not need sealing as often since water can run off more efficiently and is less likely to pool.
Your Local Climate
Harsher climates call for more frequent roof sealing. Rough weather can break down the sealant much faster than climates without intense sun, heat, or rain. Areas with high winds may also have tree branches and other debris scratching or damaging the roof. Moreover, repetitive cycles of rain and sunshine can cause the sealant to expand and contract quickly, causing it to need frequent recoating.
How to Tell When a Flat Roof Needs Coating
It’s important to seal flat roofs as a pre-emptive measure instead of waiting for leaks or ponding. Any signs of leakage, ponding, or structural damage indicate your roof needs coating. But even if you don’t notice such signs, a flat roof should be sealed every five years to safeguard it from water damage.
Overall, roof sealing is a very critical part of keeping your flat roof in great shape. If you have a flat roof, you need to be vigilant about having the roof inspected annually. However, resealing won’t solve major issues. If the roof is damaged and needs repairs or replacement, it’s better to not waste money on coating the roof but fix the problems.
