Know your roof
Leaks tend to start where something breaks up the shingles: valleys, chimneys, skylights and edges. Tap a marker to see what each part does, in plain English.
Valley
The inside angle where two roof planes meet. It carries the most water on the roof.
The whole outside of the house
A detailed proposal first, then installers who protect your home and landscaping while they work.
