Bad Roof Flashing is a Real Drip!


Your roof is designed with a series of overlapping pieces, each working together to channel rain water safely down – and away – from your vulnerable areas. Most people focus on the roof covering itself: the shingles, the roof tiles, the cedar shakes, the standing seam metal panels but overlook (or just don’t know about) the critical areas. Those spots where the roof is cut.

Why is the roof cut? To get around obstacles like a chimney. A skylight. A roof valley. a plumbing vent. A bath fan. Solar panels. The list goes on.
What happens when you do everything right, except that last critical piece? It Leaks!

Some Common Flashing Failures


Step Flashing Leak

Step flashing is used where a roof goes sideways into a wall. Step flashing goes up the side wall as a splash guard, so to speak, to channel rain water down.

Chimney Flashing Leak

Chimneys in the Seattle area are notorious sources of leaks. From the mortar, to the flu, to the base flashing and counter flashing this thing is always eating the worst of our weather and often leaks if not taken care of with your replacement roof.

Starter Flashing Leak

Some roofers still don’t use flashing at the gutter edge, even though it’s required by code! Penny pinching can cause some serious water damage when you skip flashing at the gutter edge.
