Full Roof Tear-Off and Sheathing Replacement

On July 29, 2025, Roof Repairs CA began a detailed roofing project at 15748 Romar St in Los Angeles. The property consisted of a main home and detached garage, both in need of a full roof replacement. The aging red shingles on the garage were brittle and peeling, and signs of water infiltration were evident on the interior sheathing boards of both structures.

Our crew began with a full tear-off, removing all roofing layers down to the wood. Inspection revealed multiple problem areas—delaminated sheathing, rot, and even some exposed insulation where older framing had failed. These sections were removed and replaced with fresh plywood, and the new decking was laid down in uniform, staggered seams to maintain proper support.

This home featured multiple roof angles and valleys, requiring precise measurements and craftsmanship during re-sheathing. We used high-grade plywood and adjusted cuts to follow rooflines and flashing breaks. With structural issues addressed and new decking in place, we staged the site for shingle delivery. Rolls of synthetic underlayment were applied, including BuildMark and RhinoRoof materials, to provide enhanced waterproofing before final roofing installation.

The garage also received new sheathing and a clean layout of underlayment, prepping it to match the main home’s improved appearance and durability.
