Repair
Leaks, flashing, damaged shingles and what a repair visit usually involves.
Most roof repairs start with a symptom indoors: a brown ring on the ceiling, a drip in heavy rain, daylight showing in the attic. The place water shows up is rarely the place it got in, because it runs along the rafters and the decking before it drops.
These guides cover the usual sources of leaks, such as flashing, pipe boots, lifted shingles and blocked valleys, and what a proper repair visit includes. Knowing that lets you tell a real fix from a dab of sealant.
