Complete Shingle Roof Maintenance and Chimney Sealing in Los Angeles

On July 12, 2025, Roof Repairs CA completed a comprehensive shingle roof maintenance project at 16931 Marlin Pl, Los Angeles, CA 91406. The roof was showing signs of wear due to prolonged exposure to sun and weather, with specific vulnerabilities around the chimney and roof penetrations.

The primary concern was the brick chimney, where base flashing had begun to peel and degrade. We carefully cleaned the perimeter, applied new roof mastic, and sealed all flashing joints to prevent future water intrusion. Alongside the chimney, we addressed several vent pipes with deteriorated seals and rusted collars. Our team removed failing mastic, reseated the boots, and applied new sealant to create watertight transitions.

The satellite dish mount, which penetrated through the roofing membrane, was also reinforced. Loose shingles and granule loss near the ridge were noted and corrected, and all ridge cap shingles were inspected and secured. These detailed repairs are essential in a property of this age and layout, where multiple valleys and transitions create opportunities for water intrusion if left untreated.

The project wrapped with a full roof system review, where we cleared debris, ensured flashing integrity, and left the home fully sealed and protected.
