How do you find where a roof leak is coming from?
Water often enters in one place and shows up somewhere else, because it runs along rafters and felt before it drips. That is why the damp patch on a ceiling is rarely directly under the hole.
We start with what you have seen: where the stain is, whether it appears only in heavy rain or with wind, and when it began. Then we look at the roof from outside, from a ladder or from the loft. We check the likely culprits first, including flashings, valleys, ridge tiles and slipped slates, and look at the underside of the roof for staining and wet timber.
Sometimes the cause is not the roof at all, such as a blocked gutter, a cracked pipe or condensation in the loft. We will tell you if that looks likely. Our roof inspection service is useful when you want a full written view rather than a quick fix.
