Rated 4.5 out of 5 by 14 reviewers.
Rated 1 out of 5 by 10 year roof seal sadly this item did not seal my flat roof, and the water continued to find its way in 18 August 2015
Rated 5 out of 5 by EXCELLENT I HAVE USED THIS PRODUCT FOR MY FLAT ROOF AND FIND IT EASY TO USE, AND I AM VERY PLEASED WITH THE RESULTS. 08 November 2012
Rated 5 out of 5 by Excellent product This is the sort of product that fills you with confidence from the moment you open the tin. Applied thick, it dries into a tough flexible coating that easily fills cracks, holes or splits in almost any surface, I have used it to seal a leak on my flat bitumen roof, to tidy up a rusty metal drain cover which I had repaired and to re-seal some wood window trim which was weathering badly. It rained before the roof patch had dried properly - but the patch still dried out a few days later and is absolutely fine. Whether you slop it on thick or work it on like paint (it dries matt black), this is a very versatile product. 04 August 2012
Rated 5 out of 5 by Excellent Quality Spreads on the felt roof easier than gloss paint on wood. Touch dry in 2 hours, and ready for second coat following day. Do not put on when wet or chance of rain, it liquifies and runs. overall, marvelous product. 09 May 2012

Rated 5 out of 5 by Thompsons Roof Seal Excellent product easy to use. Quick drying and can be reapplied for badly damaged areas. Lasts through the hot and cold spells. Surface needs to be cleared of loose debris and dry. This is the best product I have ever used for roof repair and I would highly recommend. 17 November 2011

Rated 4 out of 5 by Excelent product Great product for a reasonable price. Only problem is that it wont last 10 years!!! It would weather in about 3-5 years but all it needs is to recoat it. Good product for emergency repairs. 06 September 2011
