Second-Floor Restoration Project: Roof Overhang Runoff → Window Intrusion
This is a real second-floor water intrusion job. Below is what was found, how the moisture pathway was identified, what was opened, how the structure was dried, and how the area was rebuilt back to a clean finish.
Job facts
- Location: Not provided
- Level: Second floor
- Area affected: Interior wall cavity at the window area (leak noted at the corner where the ceiling meets the wall)
- Cause: Roof issue causing rainwater runoff along an exterior overhang to the wall and window area, allowing water to enter through the window
- Materials affected: Drywall, insulation, wood framing, interior paint/finish
- Work performed: controlled opening, removal of damaged drywall, removal of wet insulation, structural drying, rebuild & paint
- Mitigation & drying: FloodDry Water Damage Restoration
- Rebuild / finish: FDtouch
- Documentation: photo documentation + moisture meter checks (specific readings not legible in provided photos)
What we found
Water was leaking at the corner where the ceiling meets the wall on the second floor due to a roof issue. Inside, the affected drywall became saturated and lost structural integrity, and the paint began to peel. In the photos, visible water streaking and paint/finish damage can be seen near the window area.
How the water got in
An exterior roof overhang extended from the roof. During rainfall, water flowed along the overhang onto the exterior wall, then toward the window area. From there, water entered through the window and migrated into the wall cavity. This condition occurred over a long period of time.
Note: mitigation and interior repairs hold best when the exterior source (roof/overhang drainage path and window assembly) is corrected.
Why we opened the wall
The drywall in the wall became saturated and lost structural integrity, and the insulation was wet. To remove damaged materials and expose the framing for proper drying, the affected section of wall was opened.
Mitigation & drying steps
- Inspection: the affected area was inspected and the long-term intrusion pathway was documented.
- Removal of damaged materials: damaged drywall was removed and wet insulation was taken out.
- Structural drying: the wooden framing was thoroughly dried using professional drying equipment (air movers/dehumidification shown in photos).
- Monitoring: moisture meter checks were performed during the process (specific readings not legible in the provided photos).
Repairs & finish
Once the structure was completely dry, new dry insulation was installed, the wall was reassembled with drywall, and finishing and painting were completed to return the area to its original condition.
Takeaways for homeowners
- Paint failure can be a warning sign. In this project, peeling/failed paint corresponded with saturated drywall behind the finish.
- Long-term intrusion can damage more than the surface. Wet insulation and impacted drywall were found inside the wall cavity.
- Access enables proper drying. The affected wall was opened so damaged materials could be removed and framing could be dried.
- Stop the pathway. The pathway (roof overhang runoff to the window area) highlights why correcting exterior drainage/window issues matters.
