Product Details

Get your flat roof ready for bad weather with Thompsons 10 Year Roof Seal – it seals up any damaged or worn areas, repels water molecules and adds an extra binding strength to the surface. As a result, it's commonly used on felt roofs for sheds, but will also work on asphalt, slate, tiles, concrete, brick and corrugated metal. It helps to keep the inside of your shed well insulated and free from drips or leaks.

The roof seal has excellent UV resistance, meaning the deep black colour won't fade in the sun. After six hours, when the first layer has fully dried, a second coat can be applied, which provides extra protection from the rain.

Thompsons Roof Seal has a malleable formula that moves with the roof, so it prevents cracks from appearing and stops the surface from flaking in the heat or cold.

• Repairs your flat roof to get it weatherproof

• Suitable for use with felt, asphalt, slate, tiles, concrete, brick and corrugated metal

• Outperforms standard bitumen paint

• Flexes with the natural movement of the roof

• Resists the sun’s UV rays, so colour won't fade

• Rainproof in six hours

• Coverage of approximately 0.5m² per litre

Thompsons 10 Year Roof Seal Black 4L is rated 4.7 out of 5 by 208.
Rated 5 out of 5 by from Fabulous stuff so far Read some great reviews about this stuff and so far it hasn't disappointed. Went on (with a brush) very easily and sticks like glue to almost any surface. Water washes it off most surfaces (but needs a bit of work to clean brushes!) Looks like it's going to be very successful and leaves a rubbery but solid finish which gives every indication of moving with expansion and contraction. I used what I had left over from the roof on two wooden gates and the flat top of a 3x3 fence. again it seems to form a waterproof coating on timber and I'm hopeful that it will seal mdf/chipboard and turn that into timber that's usable outdoors!? Very pleased.

Rated 5 out of 5 by from Does the job so far. Far better coverage than a 5lt cheaper version. Easy to apply and very easy to clean brushes or trowel. Working well at the moment. Wish they did a green version.

Rated 5 out of 5 by from Excellent product covered really easily and you could see and feel how good the product is. Did 3 flat roofs one of which was leaking and so far no drips whatsoever. Really impressed so far and have enough for another coat before next winter, it goes further than we thought.
