Leaking Roof Repairs
Leaking Roof Repairs in London
A roof leak is rarely where the stain appears. Water travels along rafters and felt before it drips, so guessing wastes money. We trace the leak to its source and repair that, not just the symptom.

Leaking Roof Repairs across London
We see the same culprits again and again across London: failed lead flashings around chimneys and dormers, blocked or split valleys, cracked flat roof membranes, slipped tiles, broken ridge bedding and blocked gutters. Each needs a different fix, and the cause is often some way from the stain.
We start inside the loft where we can, looking for tracking, wet insulation and daylight, and then work outwards across the roof. When the source is found we explain it, show you photographs and agree the repair in writing.
Where roof leaks usually come from
- Chimney flashings, lead work and pointing that has cracked or lifted
- Valleys and gutters between roof slopes blocked with debris or split
- Slipped, cracked or missing tiles and slates, and failed ridge bedding
- Flat roof membranes that have split, blistered or pooled water at the seams
- Skylights, roof windows, vents and pipes where the seal has failed

How we find and fix a leak
We combine a loft inspection, a close roof survey and, where needed, controlled water testing to isolate the entry point. We do not coat a roof in sealant and hope. Repairs use the right material for the job: new lead flashings, replacement tiles or slates, new valley liners, patch or full re-lay of flat roof membranes, and new sealed penetrations.
We also check what the leak has damaged. Wet insulation, rotten timbers or a stained ceiling should be dealt with early, and we will tell you if anything needs attention beyond the roof itself.
How it works
We trace it
Loft check first, then the roof surface, to find where the water really gets in.
We explain it
You see photos of the cause and understand exactly what needs fixing and why.
We repair it
We fix the source with the right materials and make sure nearby weak points are sound.
We confirm it
We check the repair and advise you on drying out and any decorating or insulation that needs attention.
Roof leaking now?
We offer emergency call-outs across all London boroughs. Call us and we will tell you what to do straight away and how soon we can attend.
Sealing versus repairing
Some leaks can be solved with a localised repair. Others, such as an old flat roof with failing seams, are better treated with a new waterproof layer. If a coating or waterproofing system is the best answer, we will say so, and if it is not we will say that too.
What affects the cost?
Leak repairs vary from a short visit to renew a few tiles up to re-leading a chimney or relaying part of a flat roof. The price depends on the cause, access and materials. After diagnosing the problem we give you a free written quote.

Leaking Roof Repairs FAQs
How do you find where a roof leak is coming from?
We inspect the loft for water tracking and wet timber, then survey the roof surface, flashings, valleys, chimneys and penetrations. Where it is unclear we use controlled water testing to isolate the entry point.
Can a leak be fixed without replacing the whole roof?
Often yes. If the roof is otherwise sound, a targeted repair solves most leaks. If the covering is failing across the whole roof, we will explain why replacement is the better value.
Why does my roof leak only when it rains heavily or from one direction?
Wind-driven rain exposes weak points such as slipped tiles, lifted flashings and failed pointing that stay dry in light rain. It is a useful clue and we use it when diagnosing.
How long does a leak repair take?
A simple repair is usually done in a visit. If lead work or a larger section of flat roof is involved it can take longer. We confirm timing in your quote.
