How to Find the Source of a Roof Leak
Updated: Sep 15
If your roof has a mystery leak, it may be time to call a cedar roof contractor. If left untreated, a leak in your roof can lead to serious damage. More often than not, finding the source will actually take more time than it will to fix it.
Inspecting Your Roof
Performing a cedar roof inspection yourself to hunt down the source of the leak can be a frustrating task because where the leak occurs on the outside doesn't typically line up with where the water appears on the inside of your home. Finding the source of a roof leak often requires a process of elimination to evaluate the many contributing factors.
Cedar roof repair professionals recommend first finding the leak on the inside of your home. Determine whether the source of the water is indeed roof-related or if it's associated with another component like the plumbing.
Start by water testing by using a hose on a dry day. The person spraying the hose should spray in a way that simulates a natural rainstorm. They should also start at the bottom and work their way up. A second person should stay inside, watching for water ingress.
Finding the Source of Your Roof Leak
Once certain the leak is roof-related, measure the location of the leak inside using two fixed points for reference. These points should be areas you can see from the finished ceiling, as well as the attic space. For those who aren't confident in completing measurements on their own, a skilled cedar roof contractor can help you out.
After taking these measurements, it's important to check the underside of the roof from the attic to attempt to find the source. Use the measurements you previously took. Note where on the roofing the leak is originating. The exact location of the leak in the attic may differ from where it appears on your ceiling so it's important to look at a larger area.
The next step is to measure the location of the leak under the roofing materials, again using two fixed points like on vent pipes or chimneys. After taking these measurements, carefully climb onto the roof and use those measurements to find the spot on the exterior of your home. You may need to make adjustments for the depth of the walls, as well as the soffit overhangs to find the precise location.
