Pitched roofing services in Harrow
Pitched roofs in Harrow are commonly found on terraced and semi-detached homes, many of which share rooflines, valleys, and party walls. Over time, these roofs often undergo piecemeal repairs, loft conversions, or partial upgrades that introduce weak points. Our pitched roofing service in Harrow focuses on identifying where these issues occur and carrying out work that restores the roof’s integrity without causing problems for neighbouring properties.
Common pitched roof problems in Harrow
Roofing issues in Harrow often develop due to ageing materials, shared roof details, and earlier repairs carried out in isolation. Because many roofs are closely packed together, problems can spread across adjoining properties if left unresolved.
Slipped or broken tiles are common on pitched roofs across Harrow, particularly on older terraces where fixings have weakened over time. Wind exposure and roof movement can cause tiles to shift, allowing water to penetrate the underlay and affect internal ceilings.
Chimneys and shared valleys are frequent leak points on Harrow properties. Ageing leadwork, blocked channels, or poorly detailed past repairs can allow water to enter the roof space. Because valleys often serve more than one property, these issues require careful handling.
Many pitched roofs in Harrow still rely on original felt and timber battens that have exceeded their lifespan. Felt can degrade or tear, battens may rot, and nail sickness can occur as fixings corrode and lose grip, causing tiles to loosen across large sections of roof.
Traditional mortar-bedded ridge tiles are prone to cracking and movement over time. On Harrow’s exposed rooflines, loose ridges can allow water ingress and pose a safety risk, particularly where roofs are close to footpaths or neighbouring homes.

Pitched roofing materials we work with
Homes across Harrow use a mix of pitched roofing materials depending on age and construction style. Using the correct materials and fixing methods is essential to maintain durability and compatibility with neighbouring roofs.
Concrete roof tiles
Concrete tiles are commonly used on post-war housing in Harrow. They provide consistent performance and good weather resistance when properly installed and maintained.
Clay roof tiles
Clay tiles are often found on older terraces and character properties. While durable, they can become brittle with age and require careful handling during repairs.
Natural slate roofing
Natural slate roofs are valued for their longevity and traditional appearance. Repairs require experience, particularly when matching slate sizes and thicknesses on older Harrow properties.
