#4 Check the Flashing and Edges.

Another common leak area is the flashing and edges. In case you’re wondering, the flashing is the metallic placed around the roof features such as skylights.

What you’re going to be looking for is signs of rust, separation, or loose flashing. If your roof has any of these things that could be a source of leaks.

Lastly, you’ll need to check the gutter system. This goes along with #1 in checking for debris that could be clogging up the gutters. You can also run water tests on the gutters to make sure the water runs into the gutters and downspouts.

If the water is slow to drain you may have clogs that will need to be cleared out. Also, if you notice one or two leaks in the gutters you may be able to repair them yourself. Anything more than that, then you’ll need a professional.
