How is a roof leak found?
Water rarely drips where it enters. It runs along rafters and decking before it shows up on a ceiling, sometimes several feet from the source. Finding it takes a method, not a guess.
Where we start
We ask when the leak shows up, such as only in heavy rain or only with wind. Then we check the attic for wet wood, dark stains and damp insulation, and we trace them uphill to the roof.
On the roof
We look at flashing, vent boots, tile and shingle laps, valleys and any place the roof meets a wall. If the cause is not obvious, a controlled water test on one section at a time can narrow it down. Leak detection takes patience, and some leaks only appear in certain winds. We tell you what we found and what we could not confirm.
