Shingle Roof Replacement and Slope Repair in Los Angeles

On June 10, 2025, Roof Repairs CA completed a full shingle roof replacement at 1829 S Ogden Dr in Los Angeles, CA. The job involved both the main residence and a detached garage, which were both suffering from extensive wear. The upper roof had large sections of granule loss and bald spots, exposing the underlayment and creating leak-prone zones. The existing shingles were brittle, cracked, and lifting from years of UV exposure and lack of prior maintenance.

The scope began with a full tear-off down to the wood decking. Upon removal, our team found compromised underlayment, areas of wood rot, and improper slope alignment on the upper roof plane. This section had poor water runoff due to a subtle sag in the roofline, which we corrected before installing new synthetic underlayment and starter rows.

We installed high-quality asphalt shingles throughout, including new flashing around all pipe penetrations and edge lines. On the garage roof, we addressed a valley transition by reinforcing the flashing line and ensuring shingle overlap protected against water intrusion.

This restoration not only renewed the curb appeal of the property but more importantly reestablished full weather protection. With proper venting, pipe boots, and flashing seals, this roofing system is now set up for long-term performance against Los Angeles’ coastal conditions.
