Roof leaks can be hard to find, since they often run down the underside of sheathing or rafters to show up far from their actual source. The best time to try and find a leak is when itâs raining outside, or you can also mimic rain conditions by spraying water on the roof.Go in the attic and look for damp spots or water stains, trace them back to their highest point, then examine that part of the roof for any potential problems.he best time to try and find a leak is when itâs raining outside, or you can also mimic rain conditions by spraying water on the roof.

But yet, when it rains and the wind blows, we wonder if this is the day when our roof will fail. All too often homeowners blindly hope everything is okay and simply ignore their roof. But then when a roof leak occurs they panic. Of course, panic is never good! Small leaks take many years to become apparent and damage is usually not significantly increased if you need to wait to have a professional check to cause of damage. Some roofers offer free estimates and only focus on roof replacement will tell you âyes you need a new roofâ without hesitation. But that is not always the case. After all, a simple repair may keep you, your homeâs contents and the people you love dry for many more years to come. The best way to know what your roofing needs are is to have it professionally checked weather a problem is visible or not.
