Rated 4 out of 5 by easy to work with I have used Thompson's roof seal a few times now and prefer it to the bitumen based products and find it does not crack easily.It has good flexibility and can be applied easily with a paint brush and allows you to get the material into cracks or suspect areas.It is much cheaper at Screwfix than other DIY outlets. 23 Feb 2016
Rated 5 out of 5 by Great product I've used this product several times and it never lets me down. Easy to apply, dries quickly and has good performance. I stick with what I know and keep using the products that work well. This product is highly recommended. 18 Jan 2016
Rated 5 out of 5 by Great waterproofing product The product was very easy to use and after two coats we now have a water tight office roof. Product was used on asbestos sheet roofing so has enabled us to avoid roof replacement. 9 Dec 2015

Hi thanks for your question. We don't recommend the use of this product on lead I'm afraid as it will not bond sufficiently. You could consider the use of Isoflex Liquid Rubber (36010 & 29518) on lead however on this type of substrate we would always recommend the use of Isoflex Special Primer.

Hi thanks for your question, this is a product we would only recommend on the outside of a flat roof, it would not be effective on the inside of a roof.

Hi thanks for your question, Thompson's 10 Year Roof Seal is designed to extend the life of flat roofs. We wouldn't recommend it is used on pitched wooden roofs or as a substitute for felt on a flat wooden roof, I hope that helps.

My flat roof has some leaks around the skylights I had put in...will this product help to seal the whole flat roof and prevent leaks? Or is there a better solution. Thanks

Answer: 
Hi thanks for your question, if you don't know the exact location of the leak then treating the whole roof may be the answer. If a more localised repair will solve the problem then it may be worth considering Emergency Roof Seal.
