Rated 5 out of 5 by from So easy to use. This roof seal is so easy to brush on and brushes wash out in water. I certainly waterproofed the old felt on my shed roof.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from 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.

Can this product be used to paint over flat roof felt which has previously had Thompson's Emergency Roof Seal applied at the felt overlap joins?

Asked by: Ghffrhjv
Thanks for your question. If the Emergency Roofseal is weathered (1 month plus) then it will be fine to apply the 10 Year Roof Seal.

Is this suitable indoors?

I.e. On the inside of a shed roof, beams etc
Asked by: Anonymous
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.

What is the lowest temperature at which this product can be used?

Asked by: GeofW
Thanks for your question. In order for the Roof Seal to cure thoroughly and therefore be resistant to rain it must be applied at temperatures of 10 degrees C and above. This applies to both the temperature at application and throughout the drying time.

Do I need to, and is it permissible, to overpaint Roof Seal with aluminium paint?

Asked by: Eurwyn
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.

Shed roof leakage

I have recently replaced the felt on my flat roof shed and I have noticed the water is leacking from the joints and from the nails I have applied to fix the felt. Can you please advise what will be the best solution to fix the leakage.
Asked by: Navjeet
Thank you for your enquiry. The product you mention is intended for application to the whole area and would not be effective if used in this way. Thompsons Emergency Roof Seal would be a better product for your needs, it contains fibres to reinforce the area of repair/application.
