Rated 5 out of 5 by It really works, Tried a few different products over the years but this one works, give it a nice heavy coat, it dries really quick and does the job. This is the third time I have used it and no complaints. will use it again. 20 Jul 2016
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

I have a glass (The security kind) roof that has a few cracks in it that I want to seal. Would this do the trick or if not what would work?

Thanks

Answer: 
Thanks for your question. Unfortunately the Roof seal wouldn't be suitable for glass and we don't have an alternative product to recommend for this particular type of problem, sorry.

Answer: 
Thanks for your question. We generally don't recommend over painting Roof Seal, a masonry paint is unlikely to be as flexible as the Roof Seal so will not accommodate the expansion/contraction that will occur.

Thanks for your question. It wouldn't be suitable I'm afraid. Unfortunately none of the roof seals in the Thompson's range for suitable for fiberglass roofing.
