Frequently asked

Roofing Q&A

How long does a typical roof last in Los Angeles?+

In LA's high-UV, low-precipitation climate, a 30-year architectural asphalt shingle realistically delivers 20 to 25 years on a south-facing slope and 28 to 32 years on a shaded north slope. Concrete tile lasts 40 to 50 years, though the underlayment beneath it usually needs replacement at the 25- to 30-year mark. Clay tile and natural slate can last 75 to 100+ years with periodic flashing and underlayment refresh.

How do I know if I need a roof repair or full replacement?+

If your roof is under 15 years old and the damage is localized — a few cracked tiles, a single leak, flashing failure at one penetration — a targeted repair almost always makes sense. If you're past 20 years on shingles or 25 years on tile underlayment, multiple active leaks, widespread granule loss, or sagging deck areas usually mean replacement is the better long-term investment. We give you photo documentation of both options and a straight recommendation.

What's the best roof type for the Los Angeles climate?+

There's no single best — it depends on the architecture and your priorities. Architectural composition shingles (GAF Timberline HDZ, CertainTeed Landmark) give you the best value and a 25- to 30-year service life. Concrete and clay tile add 20+ years of life and superior heat performance. Stone-coated steel is the right answer in Very High Fire Hazard Severity Zones like Calabasas, parts of Bel Air, and Pacific Palisades. Standing-seam metal pairs well with contemporary architecture and lasts 50+ years.

What does a new roof cost in Los Angeles?+

As of 2026, a straightforward asphalt re-roof on a 2,000 sq ft single-story LA home runs roughly $14,000 to $22,000 with a quality architectural shingle and full tear-off. Concrete tile re-roofs typically run $22,000 to $38,000. Clay tile, standing-seam metal, and slate are bespoke — we quote those after a site visit. Hillside access, multiple stories, steep pitch, and chimney/skylight count all affect the number.

Should I file an insurance claim for roof damage?+

File a claim when damage is clearly tied to a covered event — wind, hail, or a tree strike. Don't file for normal age-related wear; carriers may flag the claim and it rarely benefits you. Before you call, get a written inspection report with dated photos. We provide one at no charge and will meet your adjuster on-site if you want a second set of eyes during their inspection.

How long does a re-roof actually take?+

A standard single-story asphalt re-roof is typically a 2- to 3-day project: tear-off and underlayment on day one, shingles on day two, cleanup and final inspection on day three. Tile lift-and-relay runs 5 to 8 days. Estate-scale work, custom metal fabrication, and multi-story complex roofs are scheduled as longer projects with a defined daily plan you receive before we start.

What permits and inspections does Los Angeles require?+

The City of Los Angeles (and most surrounding municipalities) requires a re-roofing permit for any work that includes tear-off or replacement of more than 25 percent of the roof. We pull the permit in your name as the licensed contractor, schedule the in-progress and final inspections, and hand you the signed-off permit at closeout. You don't need to be home for any of it.

How do I vet a roofing contractor in California?+

Three checks, in this order. (1) Verify the C-39 Roofing Contractor license on the CSLB website (cslb.ca.gov). (2) Ask for a current Certificate of Insurance naming you as additional insured for the project — both general liability and workers' compensation. (3) Ask for three reference projects completed in the last two years in your neighborhood, with addresses you can drive past. A contractor who can't produce all three on request is not the right contractor.

What warranty should a quality roof come with?+

Two separate warranties matter. The manufacturer's material warranty (typically 30-year to lifetime on architectural shingles, 50-year on premium tile and metal). And the contractor's workmanship warranty on labor and flashings — anything under 5 years is a red flag, 10 years is the modern standard for a quality LA roofer, and certified installer programs (GAF Master Elite, CertainTeed SELECT ShingleMaster) extend coverage further.

When is the best time of year to re-roof in Los Angeles?+

Late spring through early fall is ideal — long dry windows, predictable scheduling, and adhesive sealants set properly in warm temperatures. We work year-round and watch the 10-day forecast carefully; winter projects get tarped and sequenced so your home is never exposed to weather overnight.

Seasonal tips

Consumer tips that actually save roofs.

Walk your perimeter twice a year

From the ground, do a slow lap around the house each spring and fall. Look for displaced or cracked tiles, dark streaks on shingles, sagging gutters, and debris piling in valleys. Photograph anything that looks off. Most major repairs we do started as a small, ignored detail two winters earlier.

Keep your gutters and valleys clear before October

Los Angeles gets most of its rain in a handful of large events between November and March. A single afternoon clearing leaves and seedpods from gutters and roof valleys prevents the back-flow that drives water under shingles and tile.

Don't pressure-wash your roof

Pressure washing strips granules from asphalt shingles and forces water under tile. If you have algae streaks on a shaded slope, use a low-pressure rinse with a manufacturer-approved cleaner — or call us for a soft-wash service. It will add years to the roof.

Trim overhanging branches by six feet

Branches that brush the roof drop debris, scratch protective coatings, and give rodents and squirrels a highway to your attic. Six feet of clearance is the working number — both for roof life and for fire defense in hillside neighborhoods.

Check your attic after the first big storm each winter

A 15-minute attic walk with a flashlight after the first storm of the season catches small leaks while they're still small. Look at the underside of the decking around chimneys, vents, and skylights — those are the four places leaks start 90% of the time.

Get a roof condition report every 5 years

Even on a healthy roof, a documented inspection every five years gives you a baseline, a remaining-life estimate, and ammunition if you ever need to make an insurance claim or sell the home. We provide a written report with annotated drone photos at no charge for homes in our service area.
