Below we look at some of the key considerations when detailing valley gutters.
- Choose durable and weather-resistant materials for the valley gutter. Lead is toxic and generally only used for heritage projects. There are a number of alternatives, including PPC aluminium, PVC and other specific flexible lead alternatives.
- Design the valley gutter with a sufficient slope and gradient to facilitate proper drainage and prevent water pooling.
- Determine the size and capacity of the valley gutter based on the anticipated rainfall intensity and roof area draining into the gutter. Specify a gutter size that can adequately handle the volume of water without overflowing or causing flooding.
- Ensure that the valley gutter is properly waterproofed and sealed to prevent water ingress and leaks. Install a robust waterproofing membrane or flashing beneath the slate roof covering and along the edges of the gutter to create a watertight seal.
- Provide adequate support and fixing for the valley gutter to ensure structural stability and longevity. Install supporting brackets or straps at regular intervals to prevent sagging or distortion of the gutter under the weight of water and debris.
These are just a few of the many considerations when designing a valley gutter detail.
