Full Description

Roofs can pose problems when they deteriorate, but this Thompsons Emergency Roof Seal is a great solution. Use it to fill and bridge gaps and holes in the covering of flat roofs on homes, garages, extensions and sheds.

This sealant is waterproof – so much so that you can even apply it during a downpour. The liquid dries immediately, so if you've got a leak you can sort it out on the spot. Make sure you take a quick look at the seal once the rain stops and give the area a second coat if you need to. It's flexible and will bend with the natural movement of the roof, providing you with a long-lasting and watertight repair.

Emergency Roof Seal is most suitable for filling smaller and shallow cracks. It's black in colour, so will blend in with most roofs. Clean up your tools and any spills using white spirit.

• Immediately fills and bridges small gaps or holes

• Perfect for use on small shallow cracks

• Can be applied even in heavy rain

• Flexes with the natural movement of the roof

• Ensures a tough, long-lasting and watertight repair

Rated 5 out of 5 by from I rate yhis sealant. Top job Used it to seal around an old chimney and the tiles and flashing. Runs in the joints well and started skinning within 10 minutes. Worked well and last rain storm we had kept the water outside. Good product.

Rated 5 out of 5 by from Excellent brushable repair Excellent stuff! Just the right amount of goopiness, I discovered some pound coin sized holes in my roof and patched them up with this. Looks like it'll last until next summer when it's new roof time!

Rated 5 out of 5 by from Cured my front porch leak, can recommend it. Using Thompsons Emergency Roof Seal I fixed a leak in the flat roof of my front porch. I first brushed off the standing water and allowed it to dry as much as possible. I warmed the tin by standing it in a bucket of hot water which made the contents less viscous. Using a 2.5 inch old paint brush I then proceeded to cover as much of the roof as I could, concentrating on the areas where rain water ponds. This product is harder to spread than other Thompsons roof seals but I think you can getter a thicker coat with this which I believe will give a more lasting protection. I would recommend you have a supply of white spirit on hand to clean up afterwards as it's quite a messy job. I'm pleased to say that even though we had torrential rain the following day, the leak was fixed and not a drop came through the roof.
