Commercial
New Roof Installation in the South Bay
Complete roof replacement for South Bay homes and commercial buildings — tear-off, deck repair, and code-compliant reroofing with permits.
Why roofs
Tear Off, Don't Overlay
Layering new roofing over old hides the deck, and the deck is where the real condition is. Code limits how many layers a roof may carry, and a reroof over an existing layer means nobody inspects the sheathing for dry rot, delamination, or fastener failure until it fails in a storm. We tear off to the deck, assess it, and repair what needs repairing before anything new goes down.
Reroofing is permitted work in every South Bay jurisdiction, and plan check for a straightforward replacement is usually quick — but it is not optional, and unpermitted roof work reliably surfaces during a sale. Palos Verdes Estates adds an additional layer: exterior changes including roofing material and color can route through the Art Jury, which is a scheduling consideration rather than a formality.
Title 24 and Cool Roofs
California's energy code sets reflectivity requirements for many reroof projects, which constrains the products available for a given assembly and slope. This is most visible on low-slope commercial roofs, where a compliant single-ply membrane is typically specified in a light color for that reason. We confirm the applicable requirement during specification rather than at inspection.
What the Work Covers
- Full tear-off to the deck; assess and repair sheathing, rot, and fastener failure.
- Underlayment, ice-and-water at vulnerable details, and correct flashing throughout.
- Composition shingle, tile, metal, and low-slope membrane systems.
- Title 24 cool-roof compliance confirmed at specification.
- Permits pulled and inspections scheduled in the relevant jurisdiction.
- PVE Art Jury submittal where material or color review applies.
- Ventilation corrected — most failed roofs we replace were under-ventilated.
