Rainwater Disposal

Gutter and downpipe problems on older buildings

The gutter and downpipe system on your building removes water and helps to prevent water damage to masonry and timber. Ensuring it is working effectively is a vital part of building maintenance. Most traditional buildings have cast iron systems, some may have internal downpipes and lead-lined gutters may also be used. Cast iron has a long life if well maintained and can last for many decades. Plastic gutters may be cheaper, but have a shorter lifespan and can break easily.

Rainwater disposal checklist:

• Regularly clear leaves and debris from the gutters
• Check the downpipes are secured to the masonry
• Check condition of the joints and that water is running freely
• If you have had works done to the roof or chimneys, ensure the contractor clears the gutters of slate/ masonry debris

You can find out more by reading the HES Inform Guide ‘The Maintenance of Cast Iron Rainwater Goods’.

What you can do

• Keep all items clear of blockages allowing water to run freely and quickly from the roof by cleaning the gutters of blockages – especially in winter
• Keep the cast iron in good condition by painting it regularly
• Make sure you have lead gutters checked by a skilled lead contractor
• Owners of traditional buildings in Stirling can join the Traditional Buildings Health Check and get a regular drone survey of their roof

If you get your roof checked annually, ask your roofer to look over the guttering for you. Some areas of guttering may be high or inaccessible. Always ensure you have a competent contractor who uses a safe access system for working at height.
