Guides and support

First off what type of roof do you have?

  • The most common in our gardens would be the shed, most sheds have a pitched roof which would comprise of a felt covering.
  • The Garage Roof, either detached or attached to a neighbor the Garage roof is often flat, and many used a felt covering, at late most homeowners opt for a new Fibreglass Roof on a garage or EPDM┬á Rubber membrane.
  • General Flat roofs like rear extensions, side extensions, outbuildings, balconies

What decision do I make?

Lets guess! Leaking Roof? A few points to consider with a leaking flat roof are:

If you can assess the leaking roof visually, this would be a good start in determining if you can simply repair the surface without too much drama. If the answer is yes then we have the perfect product to repair your roof. Take a look at these options:

Shed Roof: SHEDSEAL, a one-coat system. Paint it on from the tin.

Felt, Asphalt or Glass Fibre Roofs: CRYLICROOF is again a one-coat system that can be applied from the tin onto GRP or some rubber membranes A more advanced solution would be Tekguard Flexi GRP 


If you feel like a repair is out of reach and a new roof is required we have a couple of options.

  • EPDM – Rubber is a simple solution to a new roof , check out some how-to videos
  • GRP Fibreglass Roof Kits – We have a range of GRP kits on offer. Traditional GRP or Flexible GRP Learn before you buy┬á
  • Flexi GRP system which can be applied over existing surfaces Learn More
