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
Rated 5 out of 5 by Does what is says on't tin Great product - very easy to apply if surfaces are prepared well. Seems to give protection for a long time. 1 Dec 2015

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.

Thanks for your question, yes that would be fine, it wouldn't be suitable for areas subject to regular foot traffic however (balconies etc)

Answer: 
Thanks for your question. The Roof Seal can be applied to damp surfaces but not wet. If an urgent repair is needed use Emergency Roof Seal which can be applied to wet surfaces and even those holding standing water.
