Frequently Asked

Real answers from Roman.

How much does a new roof cost in Los Angeles?

For a 2,000 sq ft LA home, composition shingle runs $15,000–$25,000; tile roofing is $25,000–$50,000; flat roof systems (torch-down or modified bitumen) typically $15,000–$30,000. Underlayment upgrades and any sheathing replacement add to totals.

How long does roof replacement take?

Most residential tear-offs and re-roofs complete in 3 to 7 working days. Larger or more complex roofs (multi-story, steep pitch, unusual materials) can run 10 days.

What's the best roofing material for LA homes?

It depends on the house style and budget. Composition shingle is the most affordable and has 25–50 year options. Tile (concrete or clay) lasts 50+ years and suits Spanish/Mediterranean architecture. Flat roofs in LA are typically torch-down or PVC membrane.

Do you handle permit pulls and inspections?

Yes. All roof replacements in LA require a permit and inspection. We handle the entire process.

What warranty do you offer on new roofs?

Workmanship warranty from Avanti (typically 5–10 years depending on system), plus the manufacturer's material warranty (varies by product, often 25–50 years). All warranties are provided in writing.
