GRP Valley

GRP Valley

GRP Valley Troughs are designed to offer a lightweight, durable version of roof guttering compared to the more old-fashioned lead or zinc options. They’re extremely durable and create a weatherproof seal between roofs, terraced houses, or for renovating your rooftop.

Best fitted to tile and slate pitched roofs, though they’re also simple to fit to metal or GRP profiled rooftops, GRP (Glass Reinforced Plastic) valleys are more cost-effective than older expensive options and easier to lay than clay valley tiles. Easier to handle, easier to install, and cheaper overall.

As a result, they’re now one of the most popular options for roof guttering in the country. Cheaper than lead, safer than lead, and less likely to be stolen from your rooftop, GRP is the future of all valley fixtures.

At JJ Roofing Supplies, we offer fast delivery and competitive prices on GRP Valley Troughs for slate-tile rooftops and GRP Valley Troughs for classic tiled rooftops. These troughs have a long warranty and we offer a selection from the leading manufacturers in the UK.

Different Types of GRP Valley Troughs

First off, you have mortar-free valley troughs, known as dry fix. These are subtle and well-hidden gutters on your rooftop’s valleys. You won’t need to affix additional closure pieces or worry too much about the aesthetics - these dry-fix valley troughs are cut close to the roof.

Secondly, open valley troughs made with GRP have been designed to provide a durable and more cost-effective alternative to lead troughs. These are much safer and more effective than traditional lead fittings, and are 100% waterproof, year-round.

At JJ Roofing, we supply both types of GRP valley troughs, which are quickly delivered to your door to make urgent repairs or speed up the roof renovation process. There is a wide range of options here and you’re bound to find the right trough for your roof renovation or new-build.

Benefits of GRP Valley Troughs Over Traditional Options

GRP (glass reinforced plastic) has many benefits over options like slate and clay. In comparison to lead, GRP troughs will cost half as much and take half the time to install on your rooftop, whether you’re handling it yourself or leaving it to a professional roofer. This is because the reinforced plastic is so light and easy to handle, already in the right shape for your roof.

Another benefit that has to be considered, especially on new build properties or for renovations, is that they are not as valuable as lead troughs. Burglars and thieves have been known to strip down lead roof fittings. This is why it's recommended to replace your current lead waterproof guttering for GRP fixtures as soon as you get a chance.

Lastly, GRP doesn’t stain after consistent use, often comes with a multi-decade longevity guarantee (usually over thirty years), and helps prevent leaks even during severe weather conditions.
