How To Fix A Leaking Fibreglass Roof
It can be costly to replace a GRP roof and yet the problem might just be holes in your roof or gutter. How can little golf-ball sized holes end up costing you so much?

That’s why we’ve made it easier than ever to fix your own fibreglass roof, and still get an effective repair that’ll remain watertight in the long run. How? By using expert solutions that outlast other instant repairs that you’ll find in your local hardware store.

First off, a few notes on safety:

Ensure your roof or gutter is structurally stable and that you’re safe at all times

How To Clean Your GRP Roof
Start as you mean to go on. Do a thorough clean and your roof repair can be 100% weatherproof in the long run. You can pressure wash your fibreglass roof. Ensure you clean well beyond the hole and affected area. You should be left with an area free of dirt and grime.

Every kit is equipped with the powerful biocide, this was developed by the market leaders in roof coatings in the competitive markets of Scandinavia and northern Europe, and it’s now available for your fibreglass roof repair. Mix 1 part Biocide to 2 parts water. Now moss and spores won’t develop under the repairs and you can stop leaks for longer.

How To Prime Your GRP Roof
Most porous surfaces need priming to allow proper adhesion and long term weatherproofing, and your roof is no exception. This kit comes with a UV curing resin that will dry when exposed to sunlight, making it clean and easy to use. Wait for the surface to dry after your thorough clean, and then paint the primer onto the damaged area. Completely cover the hole and the surrounding area with a generous amount of primer. Wait for this to dry before applying the SpeedPatch. Drying/curing time will depend on the day’s brightness, and you can use a UV light to speed up the cure.

How To Waterproof Your Fibreglass Roof
Surface well prepared and primer all dry, and you’re ready for the main event. SpeedPatches are UV cured, so exposure to the daylight will begin to turn them rigid. With this in mind, it’s best to handle the patch carefully, keeping it as much in the shade as possible (even if the only shade that day is from you). Cut open the foil packet and cut the patch to size. Keep in mind that it’s best to cover well beyond the hole for added durability. One side of the SpeedPatch is covered with a sun-blocking tape. Keep this on until after application. This is the side that faces toward the sky. On the other side there is a clear film which you can now peel off.

Apply the speedpatch over the hole so that the sun blocking tape faces up. Apply pressure where it’s safe to do so and ensure that all areas are properly adhered to your asbestos roof. Peel off the black tape and continue applying pressure, particularly around the edges of the patch.

Bigger holes and severely chipped sheets can also be suitable for repair, although you’ve got to make sure that the speedpatch can get enough space around the damaged area.

1) Do I need any extra tools or experience to apply it?
No. This is a complete DIY kit. You’ll get everything you need to stop the leak. The only extras you’ll need is a bucket to mix the A-Clean and water together, and a soft brush for the cleaning. This can be a standard dustpan style brush, so long as the bristles are soft.

2) Why should I get a kit?
All of the products in the kit have been carefully selected. They’re generally more durable, longer lasting and easier to apply than what you’ll find at the local hardware store. Roofing contractors have been using these materials for years, and they’re now available to you. It’s also more cost effective to order a kit than to buy the items seperately.

3) How long will the repair last?
You should expecct 5-10 years, but it could be much longer, or shorter if it gets damaged. There’s no clear cut answer for this as it’ll depend on the roof conditions and future weathering. What we can say is that the butyl tapes can easily outlast many other solutions.

4) Is asbestos safe to repair?
Yes, so long as you follow HSE guidelines. Keep yourself safe at all times.

5) Why should I use butyl tape?
Butyl is a tough rubber that can handle temperate change and building movement. This sets it apart from other roofing tapes and solutions, particularly bitumen which has a reputation for cracking in the cold. The butyl is completely waterproof and forms a well adhered seal when combined with a coating or primer.

6) Why is the butyl tape foil or fleece backed?
The foil provides a UV resistant barrier to protect the rubber tape from sun exposure. And the fleece reinforced the tape and holds any subsequently applied coating.

7) Why use a SpeedPatch to cover holes?
Unlike tapes or matting, a SpeedPatch is a tough barrier that’s made from GRP laminate. This is easy to cut to size and shape around roof contours. The SpeedPatch cures when exposed to sunlight and forms a strong rigid barrier over holes. Combine this with the UV Curing primer and you’ve got a watertight seal that will go on year after year.
