Waterproofing Pitched Roofs

Waterproofing Pitched Roofs

Many pitched roofs are given little or no thought to their maintenance until they develop leakage problems. Very so often, the tell tale signs of a leakage problem is a wet or damp patch appearing on the ceiling. Occasionally, this may appear at certain times, for instance, after a heavy down pour.

Finding a roof leak on a pitched roof can be extremely difficult and at times it can be complex and involving. This is due to the fact that pitched roofs come in a variety of sizes, designs and shapes.  the resulting shape of the roof in most cases is affected by the climate and environment where you’re building, the availability of building materials, and the building’s purpose etc.

Possible causes of leaks in pitched roofs include:

  • slipped or broken slates or tiles
  • broken or slipped ridge tiles
  • blocked or cracked valleys
  • loose or damaged guttering
  • moss on the roof

So, how do you waterproof pitched roofs? They are patched by using Grey Liquid Rubber. It is an acrylic emulsion which is applied in two coats by brush to new or existing substrates. Within two to eight hours of application, dependent on the weather condition, the material dries to a tough elastic film immediately protecting the pitched roof from the ingress of water.
