Roofers in Mortlake

Tracking roof leaks and blocked rainwater routes in Mortlake

If water shows up around an upper-floor window or ceiling, the roof covering might be responsible—but overflowing gutters, chimney joints or a flat-roof edge can look similar from inside. A useful inspection follows the likely route of rainwater, not just the visible patch.

• Check open gutters and downpipes for accumulated leaves and roof debris.
• Inspect brackets, joints and end caps for leaks and movement.
• Look at slipped slates, damaged tiles and insecure ridges on pitched roofs.
• Review chimney stacks and lead flashings at roof intersections.
• Examine valleys for obstructions and deteriorated adjoining coverings.
• Assess flat rear roofs for cracking, seam defects and blocked outlets.
• Consider whether repeated leaks justify a wider roof-condition review.

Mortlake roof maintenance FAQs

Can moss or leaves in a gutter cause a wall to look damp? Yes, overflow may wet the brickwork, although masonry defects can also allow water in. Both drainage and wall condition may need checking.

Is repointing a chimney always a roofing solution? No. Mortar defects are one possibility; the leadwork and nearby roof may be the real source of a leak.

What should I describe when calling about a leak? Tell us when the stain develops, whether it is worse in driving rain, and whether the roof is pitched or flat. Photographs from a safe position can help.
