Question 1

How do I know if my roof needs repair or full replacement?

Accepted Answer

A repair makes sense when the failure is localized — a single valley leak, a cracked tile, or flashing that has pulled away from a vent. If the decking is sound and the roofing material is within its service life, a targeted repair can extend the roof by years. A full replacement is the better investment when the roof is past its expected lifespan, when multiple areas are leaking, when shingles are curling or losing granules broadly, or when the underlayment has failed. A licensed contractor should inspect the decking from the attic and the roof surface, document everything with photos, and give you an honest recommendation — not a sales pitch.

Question 2

What are the signs a roof may need replacement?

Accepted Answer

Interior water stains on ceilings or walls, granules filling the gutters, shingles that are curling, cracking, or missing, daylight visible through the roof deck in the attic, and soft or spongy areas when walking the roof all indicate the roofing system is failing. A roof near or past its rated service life — typically 20–25 years for asphalt, 30–50 for tile — should be evaluated even before leaks appear.

Question 3

What roofing materials are commonly used on Southern California homes?

Accepted Answer

Concrete and clay tile are popular for their longevity and resistance to salt air, but they're heavy and require a structurally rated deck. Architectural asphalt shingles offer the best value and perform well when rated for high wind and marine exposure. Flat roofs — common on mid-century and modern homes — require properly installed membranes (TPO, modified bitumen, or coated systems) with correct slope and drainage. The right material depends on your home's architecture, structural capacity, and microclimate.

Question 4

Does E And E Construction And Remodeling install Owens Corning roofing?

Accepted Answer

Yes. For applicable asphalt shingle installations, E And E Construction And Remodeling uses Owens Corning roofing materials. Not every roof or product qualifies for identical coverage — manufacturer warranty terms, eligible products, and component requirements vary — so we review the specifics that apply to your project during the estimate.

Question 5

What warranty comes with an Owens Corning roof installed by E And E?

Accepted Answer

Qualifying Owens Corning systems are backed by the Owens Corning Standard Product Limited Lifetime Warranty on the materials. That manufacturer warranty is separate from the 5-year workmanship warranty that E And E Construction And Remodeling provides on the installation. The two cover different things and are not combined into one warranty.

Question 6

What is the difference between the Owens Corning manufacturer warranty and E And E's workmanship warranty?

Accepted Answer

The Owens Corning Standard Product Limited Lifetime Warranty covers the roofing materials themselves for qualifying systems — including a TRU PROtection period for the first 10 years, materials-only coverage after that, blow-off coverage for the first 15 years, and StreakGuard algae resistance for the first 25 years, subject to Owens Corning's terms, eligible products, component requirements, and exclusions. E And E's 5-year workmanship warranty covers the installation labor. Owens Corning does not provide workmanship coverage under the standard product warranty, and E And E does not provide the manufacturer material coverage.

Question 7

Will E And E help with Owens Corning warranty registration?

Accepted Answer

Yes. After installation, E And E Construction And Remodeling assists homeowners with completing the applicable Owens Corning manufacturer warranty registration process through its contractor connection. Registration of the qualifying system is subject to Owens Corning's requirements and terms.

Question 8

What causes roofs to fail prematurely?

Accepted Answer

The most common causes are improper flashing at valleys, chimneys, and penetrations; inadequate underlayment; poor attic ventilation that bakes shingles from below; and using materials not rated for marine exposure. UV degradation and salt-laden air accelerate wear on inferior products. Coastal homes face faster degradation than inland homes due to constant UV exposure and salt-laden air that corrodes metal flashings and fasteners.

Question 9

Why is roof flashing important?

Accepted Answer

Roof leaks rarely come through the field of the roof. They start at penetrations — plumbing vents, chimneys, skylights, valley intersections, and where the roof meets a vertical wall. Proper flashing means step flashing integrated into the weather-resistive barrier, kick-out flashing at roof-wall intersections to direct water into the gutter, and sealant that remains flexible through temperature cycles. Reusing old flashing on a new roof is a false economy — it should be replaced on every replacement.

Question 10

Do roof replacements require permits?

Accepted Answer

Yes. In nearly every jurisdiction across Ventura County, Los Angeles County, and Santa Barbara, a roof replacement or significant repair requires a building permit. The permit ensures the work meets current building code, including wind uplift requirements, underlayment specs, and ventilation standards. A licensed general contractor pulls the permit, schedules the required inspections, and ensures the final sign-off so your roof is documented and insurable.

Question 11

How long does a roof replacement take?

Accepted Answer

Most residential roof replacements are completed in 2–4 days of active work, weather permitting. Larger or more complex roofs may take up to a week. The property should be protected and the site cleaned up daily throughout the process.

Question 12

What should I look for when choosing a roofing contractor?

Accepted Answer

Verify a valid California contractor's license on cslb.ca.gov, confirm they carry general liability and workers' compensation insurance, and ask for references from recent roofing projects. Ensure they pull permits, use materials rated for your climate, and provide a written warranty. Avoid contractors who reuse old flashing or skip underlayment — both are common shortcuts that lead to premature failure.

Question 13

What should be included in a roofing estimate?

Accepted Answer

A thorough roofing estimate should itemize tear-off and disposal, deck repair (with a per-sheet rate for rotted plywood), underlayment type and brand, flashing material and locations, the roofing product with manufacturer and color, ventilation components (ridge vent, soffit vents), drip edge, and cleanup including magnet sweep. It should also state whether permits are included, the estimated timeline, and the warranty terms — both workmanship and manufacturer. A vague lump-sum bid makes it impossible to compare contractors apples-to-apples.

Question 14

How long do common roofing materials last?

Accepted Answer

Architectural asphalt shingles typically last 20–30 years, concrete tile 40–50 years, clay tile 50–100 years, and flat-roof membranes (TPO, modified bitumen) 15–25 years depending on quality and installation. These ranges assume proper installation with correct underlayment, flashing, and ventilation. Coastal exposure to salt air and UV can shorten service life by 15–25% compared to inland installations. A roof near the end of its rated life should be evaluated proactively, before leaks cause interior damage.
