Pitched Roofing

What is pitched roofing? A pitch is the angle of a roof described as a degree, the higher the degree the steeper the slope.
A pitched roof has the benefit of naturally carrying rain water down towards the eaves and guttering of a roof for dispersal.

When installing any new roof a series of steps are essential. First a breathable roofing felt / membrane is fitted tightly to the rafters or trusses which form the structure of the roof.
Next pressure treated 50x25mm C16 graded battens gauged and fixed to the size of tile which is being laid upon them.

Commonly tiles or slates are used to cover a pitched roof as these are extremely hard wearing materials. Tiles come in many different shapes, sizes, colours and a range of materials including concrete, clay, slate and composite. Pitched roofs are the most hard wearing and durable roof installations available on the market.

Our new pitched roof installations come with a comprehensive 25 year warranty included, so you can rest easy knowing your home is protected from the harsh British weather conditions.
