Common Roof Repair Problems in Streatham
Roof repairs in Streatham are often linked to ageing tiled roofs, chimney junction failures, and poor rainwater run-off. Many problems develop gradually and only become noticeable once water starts entering the property.
Tiles can crack or become loose over time, particularly after strong winds, allowing rainwater to reach the roof underlay and timber structure.
Lead flashing can deteriorate or lift as it ages, creating gaps that allow water to track into the roof space and walls.
Leaves and debris can block gutters, causing rainwater to overflow back onto roof edges and into walls or ceilings.
As ridge mortar breaks down, ridge tiles can shift or loosen, opening gaps that allow wind-driven rain to penetrate the roof.

Roof Repair vs Roof Replacement
Not every roof problem means you need a full replacement. In many cases, a professional repair is enough to stop the issue, protect your property, and extend the life of your roof.
When a Roof Repair is Usually Enough
A repair is usually suitable when the problem is localised. This includes a small leak, slipped or broken tiles, failed flashing, or damage caused by recent weather. If the underlying structure is sound and the rest of the roof is in good condition, a targeted repair is often the most sensible and cost-effective option.
When a Roof Replacement May be Recommended
Replacement is typically only recommended when damage is widespread or recurring. If multiple areas are failing, the roof covering is reaching the end of its lifespan, or the structure beneath has deteriorated, repairs may only offer short-term relief. In these cases, a replacement can prevent ongoing issues and repeated call-outs.
Our approach is simple. We inspect the roof, explain what we find, and talk you through the options. If a repair will do the job properly, that’s what we recommend. If a replacement is genuinely the better long-term solution, we’ll explain why, with no pressure either way.
How Our Roof Repair Process Works
We keep roof repairs straightforward and transparent. From the first inspection to the final sign-off, you’ll know exactly what’s happening, why it’s needed, and what it will cost before any work begins.
Inspect the Roof and Identify the Issue
We start with a thorough inspection to locate the source of the problem, not just the visible symptoms. This includes checking tiles or slates, flashing, ridges, valleys, and any areas where water could be getting in. The goal is to identify the cause of the issue so the repair actually solves it.
