How do I know if my roof valley needs repair?

Common signs of valley damage include damp patches on ceilings, visible cracks in the lead or mortar, and a buildup of debris that causes water to overflow. We provide free inspections across Kildare and Dublin to assess valley integrity.

Do you repair lead and tile roof valleys?

Yes, GJP Roofing LTD specializes in repairing and replacing lead valleys, tile valleys, and GRP dry valleys. We ensure all joints are watertight to prevent internal water damage.

Can a blocked roof valley cause leaks?

Absolutely. If leaves, moss, or silt block your roof valley, water cannot drain away properly and will often back up under the tiles, leading to significant leaks. We offer professional cleaning and repair services to keep your valleys clear.

What is a roof valley?

A roof valley is the internal angle formed where two sloping roof planes meet. Valleys are key components in roof design, serving as the primary channel for water runoff. A compromised valley can lead to leaks, water damage, and even structural deterioration over time. At GJP Roofing, we understand the unique challenges that different roof types present, including tiled roofs, slate roofs, and metal roofs, ensuring we apply the most effective repair techniques for each scenario.
