Why it matters in LA

Our climate is hard on roofs.

Los Angeles roofs take a beating — relentless summer UV, Santa Ana winds, and increasingly heavy winter atmospheric rivers all stress the roof, your home's first line of defense. A twice-yearly check catches small problems while they're still cheap to fix. As a licensed roofing, solar and battery contractor (CSLB #1055444 / #1031989) and an Owens Corning Preferred Contractor, we inspect, document, and give you an honest call. Need a fix now?

The checklist

9 warning signs you may need a new roof.

  • →1. Curled, buckled or cupping shingles. Edges lifting or bending back signal UV degradation, poor ventilation or failing underlayment — common after about 15 years of LA sun.
  • →2. Missing shingles after wind events. One or two can be repaired; recurring blow-offs after every Santa Ana mean the adhesive seal has failed roof-wide.
  • →3. Granules in your gutters. A few is normal early on; cupfuls of sandy granules mean the shingles are wearing out and the roof is likely near the end of its life.
  • →4. Moss, algae or lichen growth. Common on shaded streets; thick moss holds moisture against the roof and lifts shingles apart, accelerating rot.
  • →5. A sagging roof line. A visible droop or dip between rafters points to water-damaged decking or failing structure — have it inspected right away.
  • →6. Daylight in the attic. Pinpricks of light through the decking mean gaps where water will follow; dark stains or soft wood confirm active intrusion.
  • →7. Interior ceiling stains. Brown rings mean water has already passed the shingles, underlayment and decking — the stain is the last sign, not the first.
  • →8. Reaching material lifespan. Asphalt shingle generally fades around 18–22 years; tile lasts far longer, but the underlayment beneath it typically needs replacing well before the tile does.
  • →9. Rusted or damaged flashing. Flashing around chimneys, vents, skylights and valleys is the #1 leak source — check for rust, separation or cracked sealant.

Seeing three or more of these together usually means it's time for a professional assessment rather than another patch.

Repair or replace

A simple decision framework.

Whether to patch or replace comes down to the roof's age and how extensive the problem is — not a flat dollar rule. Use this as a starting point, then get a written estimate:

Pouring money into a failing roof rarely pays off; proactive replacement protects the home before interior damage starts. For typical 2026 ranges by material, see the Los Angeles roof replacement cost guide, or for a targeted fix, roof repair. Financing is available for qualified homeowners.

By roof type

What we inspect, by material.

The warning signs and the fix vary by roof type. We inspect and service all the common Los Angeles systems: asphalt shingle, clay & concrete tile (where the underlayment is the real waterproofing), flat & low-slope systems prone to ponding, and standing-seam metal. We also confirm attic ventilation (trapped heat bakes shingles from below) and whether California Title 24 cool-roof rules apply to a replacement.

Before you go solar

Inspect before you add panels.

Solar hardware is designed to last around 25 years, so mounting it on a roof with only a few years left is a costly mistake — you'd pay to remove and reinstall the array later. If the roof is aging, replace it first. See solar-ready roofing for how we engineer the roof for a future array, our guide to roof replacement before solar, or compare an integrated Tesla Solar Roof when the roof needs full replacement anyway.

No pressure · Free assessment

Schedule your roof inspection.

Don't wait for a significant failure. We'll assess the roof, document what we find, and give you a written, itemized estimate — repair or replacement, your call.

Roof inspection FAQ

Questions LA homeowners ask.

How often should I inspect my roof in Los Angeles?

Twice a year — in spring after the wet season and in fall before the rains return — plus a check after major Santa Ana winds, hail, or unusually heavy rain.

How can I tell if my roof needs replacement?

Watch for curled or missing shingles, heavy granule loss, a sagging roof line, daylight or stains in the attic, interior ceiling stains, rusted flashing, or a roof past about 20 years. Three or more of these usually means it's time for a professional replacement.

Do you offer roof reviews in Los Angeles?

Yes. We provide a free, no-pressure roof assessment and a written, itemized estimate after reviewing your roof. Call (833) 446-6387 or start a roof estimate online.

Should I repair or replace my roof?

It depends on the roof's age and how extensive the problem is. A sound, newer roof with a localized issue is usually a repair; an older roof, or one with widespread or structural damage, is usually better replaced. We give an honest recommendation after inspecting.
