Shingle Roof Leak Repair and Wall Transition Sealing in Santa Monica

On June 12, 2025, our crew completed a precision roof leak repair at 2613 24th St in Santa Monica, CA. The homeowner reported visible staining and signs of a leak along the exterior wall and ceiling line, particularly near a section where the upper siding met the shingle roof. Upon inspection, our team discovered an exposed opening at the base of the siding that had not been properly sealed during prior construction or remodeling work. This open seam created a direct path for water intrusion during heavy rain or coastal fog.

We cleaned the area thoroughly, applied durable roof flashing tape, and sealed the transition with high-grade exterior roofing mastic to stop future leaks. Our work extended along the base of the small upper roof where the wall projection sits above the first floor. We also inspected and re-sealed the shingles around vent pipes and other protrusions using roofing cement to ensure no gaps were present.

During the inspection, we noted some shingles that had lifted slightly along the eaves and ridge cap. These were reset and secured to prevent wind uplift and granule erosion. Our technician also checked for granule wear across the field of the roof, which was in overall good shape except for the area surrounding the leak. By resolving these issues now, the client avoided costly interior water damage and prolonged the lifespan of their entire roofing system.
