Trace leaking roof faults across your London property

Visible and hidden defects checked. Pitched and flat roofs covered. Guaranteed repair workmanship.

Leak detection without the guesswork

Follow the water route

We check how water may have travelled before it reached the visible stain.

Inspect connected details

We examine nearby flashings and junctions that could undermine a local repair.

Record useful clues

Your notes about timing and weather help us narrow down the likely source.

The ceiling stain may not mark the entry point

Water rarely respects a straight line. It can enter higher up the roof, follow felt or timber and appear indoors some distance away. Our leaking roof repair starts by tracing that route rather than assuming the wet patch sits under the defect. We check coverings, valleys, ridges, flashing, flat-roof surfaces and penetrations for visible damage and underlying weakness. Tell us where the water appears, when it began and which weather brings it on. Recent storm damage or earlier roof work can also provide useful clues during the assessment.

Restore one continuous weatherproof barrier

Once we locate the likely entry point, we examine the surrounding detail for anything that could let the leak return. Replacing one cracked tile won't help if failed flashing beside it remains open. We set out a repair that deals with the source and reconnects the weatherproof layers around it. The exact work depends on safe access and what the roof reveals, but we explain the scope before proceeding. Clear photographs and notes about the leak help us prepare, while an on-site inspection confirms what must be repaired.

Frequently asked questions

Why does the roof leak only in certain weather?

Wind direction and rainfall intensity can expose a gap that stays dry in lighter weather. Blocked drainage may also cause water to back up. Tell us when the leak happens so we can inspect the roof details most likely to be involved.

Can you find a leak above an internal stain?

We trace likely routes through the roof system, but the outside entry point may not sit directly above the stain. We inspect coverings, junctions and penetrations, using the internal location as one clue rather than the whole diagnosis.

Will sealing the visible gap stop the leak?

Only if that gap is the true source and the surrounding layers remain sound. Water may be entering through a nearby valley, flashing detail or failed seam. We assess the connected area and repair the weatherproof barrier rather than guessing.
