Dry Rot Around Windows and Eaves: Causes and Repair Scope

Exterior repairs must manage water from the roof surface all the way away from the foundation. A cosmetic patch can hide the route without stopping it.

Start with the actual condition

Wood. Wood decay requires moisture, so source correction comes before finish repair.

Determine. Determine whether damage is trim, sheathing, framing, or connection related.

Replace. Replace unsound wood and restore flashing or drainage details.

Step-by-step decision process

1. Wear the scope. Wear eye and hand protection around broken glass.
2. Cover the scope. Cover the opening without creating a fall or egress hazard.
3. Separate the scope. Separate temporary security from final glass and frame repair.
4. Inspect the scope. Inspect from the ground and from safe interior access points.
5. Record the scope. Record the location, weather, direction, and timing of the symptom.

Scope and documentation

For dry rot around windows and eaves: causes and repair scope, require the proposal to name the failure location, water-management detail, damaged layers, repair boundary, matching limits, access method, protection, disposal, and inspection or permit responsibility.

Common mistakes

• Walking on wet, steep, brittle, or damaged roofing.
• Sealing over drainage openings or wet materials.
• Choosing replacement before the failure boundary is established.

Questions to resolve

• Where does water or movement begin, and where does it become visible?
• Which layers will be opened, replaced, dried, or left in place?
• How will the repair tie into flashing, drainage, and adjacent materials?
• What test or inspection confirms the exterior is closed correctly?
