Catch fibreglass issues quickly.

Most grp roofing problems can be easily repaired uncostly and fuss-free if caught early enough. However, if unattended, these issues can affect the roofing structure, become unrepairable, and cause expensive damage.

Can GRP roofs be repaired?

We hope your new roofing never needs repairing, but the simple answer is yes, it can! Suppose the previous grp installers properly prepared and top coat the entire fibreglass resin. In that case, you shouldn’t need the installer to revisit for the expected lifespan of the fibreglass roof. Still, damage can and does happen, and you can undoubtedly fix grp fibreglass roofs.

Common fibreglass roof problems

Even though fibreglass roofing is generally highly stable, the material may deteriorate over time or crack. The result is that holes appear in the sheet, which can be fixed by catching them. An adequately built fibreglass roof will last for decades. Below are some common problems encountered when a homeowner has a failed fibreglass roof.

Can a GRP Fibreglass Roof be repaired?

As a professional in the flat roofing industry, a GRP fibreglass flat roof can be repaired, unlike some other systems. GRP fibreglass roofs are known for their weather-resistant properties and durability. Still, over time, they may require a touch-up.

Thankfully, a relatively straightforward fix involves applying a coat of resin, laminate and fibreglass to the affected area. It’s essential to note that the repair’s quality may affect the roof’s overall guarantee.

Therefore, I recommend getting a professional quotation to ensure your roof receives the best repair possible with minimal impact on its warranty.

Can you GRP over GRP?

When faced with ponding problems on your roof, acting fast and calling a qualified roofer is essential. Adding another layer of GRP coating to the affected area may seem like a quick fix. Still, it will only result in a thin, weak, easily broken layer. To tackle this problem effectively, it’s vital to apply all layers of the GRP system again or even consider starting from scratch if the pooling is severe.

The good news is that fibreglass crack repair sealants can be effective for sealing cracks. The sealant can be pressed into the crack to create a smooth and seamless appearance. So don’t wait; take care of your GRP sooner rather than later!
