Water ingress to your roof

"Water ingress" simply means water getting in where it shouldn't — and through the roof it has many routes.

Where water gets in

Beyond obvious leaks, water enters through failed flashing, cracked mortar, blocked valleys and gutters, gaps around chimneys and rooflights, porous or cracked tiles, and failed flat-roof seams. Penetrating damp through the roof is often mistaken for rising damp or condensation.

The damage it does

Left unchecked, water ingress rots timbers, ruins insulation, stains and blows plaster, damages wiring, and encourages mould. The cost of the damage inside frequently exceeds the cost of fixing the roof — which is the case for acting early.

Stopping it for good

A roofer will trace the actual entry point (not just where it shows inside, which can be metres away) and recommend either a targeted repair or, where the covering and underlay have failed broadly, a re-roof. A survey is the only reliable way to diagnose it.
