Brentford sits where the canal meets the Thames. Along the water, you will find converted buildings, newer flats and plenty of flat roofs. Away from the river, older terraces have traditional pitched roofs. This guide covers the roofing issues that come with both. As local roofers covering Brentford, we see these problems often.

Flat roofs near the water
Waterside buildings can face more damp and wind than homes further inland. So flat roofs here need good drainage and sound edge details. The most common problems we see are ponding water, split membranes and failed flashings where the roof meets a wall.
When a flat roof reaches the end of its life, we usually recommend a modern felt system, EPDM rubber or GRP fibreglass. Each suits different shapes and budgets, and we explain the choice in writing.
Balconies, terraces and outlets
Many newer buildings have roof terraces and balconies. These areas often drain through small outlets that block easily. Therefore, it pays to keep them clear, especially in autumn. Blocked outlets let water build up and find its way through joints.
Pitched roof repairs on older terraces
Brentford’s older terraces mostly have slate or clay tile roofs. Typical repairs include refixing slipped slates, renewing lead flashings and repointing chimneys. In addition, the joint between the main roof and a rear addition is a frequent leak spot. We check it on every inspection.
When to call a roofer
Call us if you see damp patches on a top-floor ceiling, water pooling on a flat roof days after rain, or pieces of slate or tile on the ground. Also get in touch if a gutter keeps overflowing in the same spot.
