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

Answer: 
Thanks for your question. Roof Seal isn't suitable for application to a metal roof and if the issue is condensation forming on the inside of the roof in cold conditions it's unlikely coating the outside of the roof will help.

Thanks for your question, we wouldn't recommend the 10 Year Roofseal for this type of application, it is more suited to maintenance of existing roof coatings.

Thanks for the question. It could be used but if repairing a crack it would be wise to embed with reinforcing scrim into the first coat whilst wet to give the repair some extra strength.

Answer: 
Thanks for your question. Over painting roof seal is not something we normally recommend, the product does not require the added protection of a solar reflective paint and would not form a good base for the application of any kind of paint.

I plan to apply Thompsons roof seal onto a felt garage roof. The roof is not suitable to walk or lie flat on therefore I plan to use a roller and an extender pole. Would that work ?

Answer: 
Thanks for your question. Yes that's fine, application with a roller is perfectly acceptable. If access to the roof is an issue however just ensure the roof can be prepared adequately, i.e. removal of any dirt, dust, moss or any other loose material. Just avoid applying the product at the hottest part of the day so early morning would be better on a very hot day.
