Heavy rainfall is starting to put pressure on traditional half round or square PVC guttering systems. New deeper round, square and Ogee (which features decorative detailing that is perfect for low level roofs) PVC rainwater systems have greater capacity. They can handle a higher volume of water than their traditional counterparts, helping to keep rainwater away from your home. Another benefit of deeper PVC guttering systems is the need for less downpipes – a standard detached will only need one downpipe on the front elevation and one on the back. Not only is this enough to take water away from your roof, but it also helps to improve the overall look of your home.
