GRP Valley Troughs

GRP Valley Troughs provide a superior drainage solution for both tile and slate roofing applications. These troughs, available in versatile colour options such as blue and grey, ensure a seamless match with various roof designs, enhancing both functionality and aesthetics. The various widths available accommodate different roofing requirements, offering flexibility in installation.

What is a GRP valley trough and what does it do?

The primary function of a GRP valley trough is to direct rainwater away from the section where the two sloping parts of a pitched roof meet, known as the valley, and acts as a chamber in which the water is directed towards the gutter. This effective method means water is not sat stagnant in the valley and permeate the roof causing water damage or rot.

What is GRP and what are the benefits?

GRP stands for Glass Reinforced Plastic. It is particularly durable and weather resistant which is why it is perfect for roofing applications where extreme weather conditions may be a factor. It is also resistant to corrosion from such weather and chemicals, making it and ideal material for drainage systems. Not only is it robust, but it is extremely lightweight, so installing a GRP valley trough is quick and easy, and thus a very effective and simple way in waterproofing your roof.
