Expert Roof Valley Repairs in Orpington, Bromley & South East London

When you contact Kevington Roofing and Building LTD for a valley repair, our process is designed for clarity and effectiveness. We start with a comprehensive, no-obligation inspection of your roof valley, often utilising drone technology for hard-to-reach areas, to accurately diagnose the root cause of the problem. We don’t just patch over issues; we identify why the valley is failing. Depending on the issue, solutions can range from re-pointing crumbling mortar joints, replacing cracked or missing leadwork, to installing new, durable felt or fibreglass lining. We’ll discuss the best materials and methods for your specific roof and budget, ensuring a repair that integrates seamlessly with your existing roofing and stands the test of time.

Roof valleys are vulnerable to a range of environmental and structural factors. The constant flow of water and accumulation of debris can cause the materials to degrade over time. Extreme weather, particularly the freeze-thaw cycles common in the UK, can cause lead to buckle or crack, and mortar to perish. Poor previous workmanship, or simply the age of the original installation, can also lead to premature failure. Furthermore, blockages from leaves, moss, or even birds' nests prevent water from flowing freely, causing it to back up and seep under tiles or flashings. Understanding these common causes allows us to implement effective, preventative repairs that address the problem at its source.

Not all roof valleys are the same, and understanding the type of valley on your property helps us determine the most effective repair. The two main types are 'open valleys' and 'closed valleys'. Open valleys typically use lead or fibreglass as the main waterproof lining, visible between the two roof slopes. These are highly durable but can corrode or crack over time. Closed valleys, on the other hand, have tiles or slates cut and fitted over the valley, making the waterproof lining (often felt or lead) hidden beneath. Woven valleys are a variation where tiles are interlaced without cutting. Our experienced team is proficient in repairing, refurbishing, and replacing all types of roof valleys, selecting the right materials and techniques to ensure a flawless, watertight finish.
