Knowing you have a roof leak is usually
obvious when you see the water
spot on your ceiling. However, it can be much harder to pinpoint the cause of the
leak. You may assume your shingles are at fault, but it could be missing flashing
around a chimney, or some other entry point, that’s allowing the water to get inside
your attic. Once inside the attic, water can travel along rafters and other horizontal
surfaces making it difficult to find the exact entry point.
If shingles are missing, cracked or otherwise damaged, water can, over time, begin
to leak into the home. A leak can start out small and slowly cause a lot of damage
if a warning sign is ignored.
Water entry can also be caused by an ice dam. Ice dams are formed by the continual
thawing of snow over the warmer portions of the roof and refreezing over the cold
eave. The ice dam can cause water to backup under shingles. If your roof doesn’t
have an ice & water underlayment installed under the shingles, you could be
experiencing leaks. Download this guide to learn more about taking action against ice damming.
