How we put it right

The problem

A newly built extension had been fitted with roof tiles and roof windows that weren't suitable for its shallow pitch. Water was tracking through the tile laps by capillary action, causing repeated leaks.

Why the work was needed

The original roof design hadn't properly allowed for the low pitch. A specialist system was needed to drain water effectively and give reliable long-term weather protection.

What the homeowner wanted

The replacement products had to be specifically approved for the roof's shallow angle.

The extension also needed to keep its natural daylight, through correctly specified low-pitch roof windows.

The challenge

Low-pitch roofs are more prone to leaking when they're installed incorrectly or with the wrong materials. Everything we installed had to be made specifically for low pitches.

The work was carefully sequenced as a strip and replacement, so the roof stayed weatherproof throughout.

The roof now uses products designed for its shallow pitch. Correctly specified tiles, roof windows and detailing let rainwater run off effectively, removing the capillary action risk created by the original covering.
