We know Simi Valley’s roofs: the 1960s ranch tracts off Erringer, the newer hillside builds above the 118, the flat roofs on mid-century patios, and the wind exposure every homeowner learns about during their first Santa Ana season. Dispatch and scheduling are coordinated from our Los Angeles office, and our crews serve Simi Valley locally every week.

Why Mercer Roofing Co Woodland Hills Is Simi Valley’s Preferred Roofing Company Company

Homeowners here don’t want a stranger walking their roofline. They want to know who’s coming, what they’ll do, and what it costs before anyone climbs a ladder. That’s exactly how we operate. Before any technician arrives at your Simi Valley home, we send their name and photo. They arrive in a marked uniform. They hand you a photo ID badge at the door. Every price is in writing before the first nail comes off the truck. That’s the Threshold Verified standard, and every Mercer location is contractually held to it.

Grant Whitlock leads our team, and he’s built our Simi Valley reputation on one simple rule: if the work isn’t right within 365 days, we make it right. Every repair includes a written guarantee. If a repair fails, the second visit is free. No fine print. No arguing. Just a roof that stays fixed.

We work with manufacturer-recognized shingle brands including GAF, CertainTeed, Owens Corning, and IKO. We stock common parts for Simi Valley jobs, so most repairs don’t wait on a supply-house run.

Free Roof Estimate in Simi Valley

Every free roof estimate in Simi Valley starts with a thorough inspection of what’s actually on your roof, not a drive-by glance from the street. If your home is one of the 1960s-70s ranch tracts, we’ll check for the specific issues those roofs are famous for: worn wood shake, brittle early composition shingles, and that brutal Simi Valley sun doing its slow work. The estimate is free, it’s in writing, and no work begins until you approve the line-item price.

What We Inspect Up Front

We walk the roof, check flashing and penetrations, and – when an older tract home is involved – we’ll look in the attic at the decking. That last step matters more in Simi Valley than almost anywhere else in Ventura County. Roofs from the 1960s and 70s often have spaced sheathing underneath, and if we find it, we’ll tell you before you sign. No surprises after tear-off.

The Written Quote

You’ll get a line-item breakdown: materials, labor, decking if needed, permit fees, and haul-away. Every number is fixed. If we find something unexpected during the job, we stop and talk to you. You approve any change in writing. No change orders with mystery pricing.

Roofing Contractor in Simi Valley

Choosing a roofing contractor in Simi Valley means choosing someone who understands hillside grading, wildfire codes, and the way Santa Ana winds punish a roofline. We pull permits, schedule inspections, and handle the whole job from tear-off to final walkthrough. For ranch homes with low-slope roofs, for hillside custom homes with steep pitches, for detached shops and ADUs on acreage – one contractor, one written quote, one year of protection.

County vs. City Permitting

Reroofing in Simi Valley runs through Ventura County in many unincorporated areas, which can add steps that a city permit doesn’t. We handle the paperwork, know which office to file with, and schedule the inspection so you don’t have to chase a county inspector. That’s part of the quote, not an afterthought.

Scoping Acreage Properties

Building on acreage changes the math. Longer material hauls, equipment access across open lots, septic and well setbacks that affect staging, and outbuildings that need their own attention. We scope all of it before quoting, so the number you see is the number the job costs. If you have a detached shop, barn, or ADU, we can include it in the same estimate as the main house.

Trusted Brands We Service in Simi Valley

We install and repair Owens Corning, IKO, Atlas, and Tamko roofing systems, plus GAF and CertainTeed when the job calls for it. Every brand we work with carries a manufacturer warranty, and we back our installation with the 365-Day Done Right Promise. For Simi Valley homeowners in wildfire risk zones, we stock Class A fire-rated options from Atlas and Owens Corning locally, which keeps quoted lead times honest. No waiting on a truck from LA when your roof needs work now.

In Simi Valley’s older tracts like the Bird Streets off Erringer Road, roofers often find original spaced sheathing under wood shake that must be resheathed before reroofing – a cost and delay that doesn’t occur in newer neighboring cities like Moorpark or Thousand Oaks, where most roofs already have solid decking. That’s the single biggest reason two homes with identical square footage can quote thousands of dollars apart in this city.

On a ranch-style home in the Bird Streets off Erringer Road, our crew peeled back three layers of old wood shake and composition only to find original 1×6 spaced sheathing with gaps wide enough to drop a hammer through. We resheathed the entire roof with 7/16 OSB, added ice and water shield at all valleys and penetrations, then installed GAF Timberline HDZ architectural shingles with a high-wind nailing pattern rated for 130 mph – ready for the next Santa Ana.

Common Roofing Company Problems We See in Simi Valley Homes

• Spaced sheathing on 1960s-70s tract roofs: Original 1×6 boards with gaps mean your new shingles have nothing solid to nail into. Code requires resheathing before reroofing, and we catch this during the estimate, not after tear-off.
• Santa Ana wind damage on flashing and ridge lines: Fall winds in Simi Valley routinely lift shingles at the eaves and peel back flashing at valleys. We use high-wind nailing patterns and starter strips rated for the gusts this city actually gets.
• UV degradation from intense summer sun: Simi Valley gets more direct sun than coastal Ventura County, and that heat breaks down shingle granules faster. Roofs here age out sooner, which means more frequent inspections are the smart play.
• Wildfire ember intrusion on hillside homes: Hillside properties above the 118 sit in designated wildfire risk zones. Class A materials and proper eave details aren’t optional there – they’re what keeps embers out of your attic during a red flag day.
