A roof leak is water entering through the roof system or related exterior details. Not every interior water stain is automatically a roofing leak, though. Condensation from high humidity, attic ventilation issues, or a leaking plumbing fixture can sometimes look like a roof leak from inside the home.
Why It Matters
Small leaks can damage insulation, drywall, decking, framing, and interior finishes if they are not found and corrected.
Common Problems
Common leak sources include pipe boots, valleys, chimney flashing, roof-to-wall intersections, ice dams, missing shingles, and improperly sealed penetrations. Other issues can mimic a roof leak, including condensation, bathroom or kitchen exhaust moisture, high indoor humidity, and plumbing leaks above or near the stained area.
Building Codes & Industry Standards
Roof assemblies should be installed to shed water and resist weather intrusion according to manufacturer instructions and applicable code requirements.
Exterior Echelon Notes
Exterior Echelon looks beyond the interior stain and evaluates roof details, drainage patterns, attic conditions when accessible, and visible exterior conditions to help identify the likely leak source.
