Roof Replacement

We don't do shortcuts on replacements. Tear off the old roof, check the decking for soft spots, install synthetic underlayment, drip edge, starter strip, shingles, ridge vent. The whole system. Your roof is only as good as the layers underneath.

roof repair
SAME-DAY

Roof Repair

Roof repairs get worse when you ignore them. A $400 flashing repair turns into $4,000 of water damage inside the wall. Our Simi Valley crew can usually get there within 48 hours for non-emergency repairs.

storm damage repair
LICENSED

Storm Damage Repair

Wind damage doesn't always look obvious from the ground. Lifted shingles, broken seals, exposed nail heads. You can't see any of that without getting on the roof. Our Simi Valley inspector does a full 27-point inspection, free of charge.

new roof installation
TOP RATED

New Roof Installation

We install new roofs on new construction, room additions, detached garages, and covered patios. Our Simi Valley crews handle residential and light commercial. Standard install time is 1-3 days depending on size.

metal roofing
GUARANTEED

Metal Roofing

Metal roofing in California makes sense. It reflects heat, handles high winds, and sheds hail better than shingles. We install standing seam, corrugated, and metal shingle panels.

shingle roofing
INSURED

Shingle Roofing

Three-tab shingles are cheaper upfront but they don't hold up like architectural. We recommend them for sheds, detached garages, and rental properties where budget matters more than aesthetics. For your Simi Valley home? Go architectural.

flat roofing

Flat Roofing

Modified bitumen is our go-to for residential flat roofs in Simi Valley. Two-ply torch-applied system with a granulated cap sheet. It handles foot traffic, thermal cycling, and California UV better than single-ply at the residential scale.

commercial roofing
SAME-DAY

Commercial Roofing

Modified bitumen (mod-bit) is still the best choice for high-traffic commercial roofs in Simi Valley. We torch-apply SBS-modified base and cap sheets over properly primed concrete or approved decking. Two-ply mod-bit systems carry 20-year NDL (No Dollar Limit) warranties through GAF, Firestone, or Johns Manville. NRCA member. We follow the manual.

gutter installation
LICENSED

Gutter Installation

Clogged gutters cause fascia rot. We see it on every other house in Simi Valley. We install new gutters with proper pitch, adequate downspout capacity, and optional gutter guards if you're done cleaning them twice a year.

Our 27-point roof inspection covers: shingle condition, granule loss, nail pops, lifting tabs, ridge cap integrity, valley flashing, step flashing at walls, drip edge, pipe boot seals, vent function, soffit ventilation, gutter pitch, downspout capacity, fascia condition, decking (from attic if accessible), and visible signs of moisture in the attic. Written report with photos emailed same day.

We keep tarps, plywood, and common repair materials on every truck. When you call (877) 586-1316 for an emergency, our crew shows up ready to work. Not ready to give you a sales pitch.

skylight installation
INSURED

Skylight installation costs $1,200-$3,500 in Simi Valley depending on size, type, and roof pitch. That includes the unit, flashing kit, interior trim, and roof patch-in. We handle everything from the outside in.

Simple Process

How It Works

1

Schedule Your Inspection

Before we quote anything, we inspect everything. Shingles, flashing, pipe boots, ridge vent, soffit, gutters. You get a full written report with photos.

2

Transparent Pricing

We price by the roofing square with all materials itemized. You'll see exactly what you're getting. Shingle brand, underlayment type, ventilation specs, flashing details.

3

Build Day

No subcontractors. Our crews, our equipment, our supervision. A project manager checks in throughout the day and does a final quality inspection before cleanup.

4

Inspection & Cleanup

Before we leave: magnetic nail sweep across the entire yard, driveway, and walkways. Dump trailer hauled off. Gutters cleaned out. Your property looks better than when we arrived.

"We had hail damage from the March storm. They met with our adjuster, got the roof approved for full replacement, and finished the job in one day. Five stars doesn't feel like enough."

"Had a flat roof leak on our commercial building downtown. Simi Valley Roofing & Maintenance patched it temporarily, then came back and did a full TPO replacement the next week. Solved a problem we'd been chasing for two years."

"Asked for a second opinion because another company said I needed a full replacement. Simi Valley Roofing & Maintenance said I only needed valley flashing repair and some shingle replacement. Saved me about $14,000. I trust these guys."

FAQ

Frequently Asked Questions

Poor ventilation causes premature aging. If your attic runs hot in summer and your shingles are curling at 15 years, bad ventilation is probably why. Missing shingles cause water intrusion and accelerate everything. We do a free inspection and give you a straight answer: repair, plan for replacement in 2-3 years, or replace now.

Yes. We handle insurance claims regularly. It's a big part of what we do in Simi Valley. Free inspection, photo documentation, claim filing assistance, and we meet the adjuster on-site. If the claim is approved, we do the work at the insurance-approved price. You pay your deductible and we handle the rest.

Depends on size, pitch, and materials. Average in Simi Valley is $12,000-$16,000 for a standard residential replacement with architectural shingles. We price by the square and itemize everything so you can compare to other quotes. Free estimates. Call (877) 586-1316.

Catch the water with a bucket, move valuables out of the drip zone, and call us at (877) 586-1316. Don't get on the roof yourself. It's dangerous and you probably can't fix it permanently anyway. We respond to emergency leaks within 24 hours in Simi Valley and tarp the area to stop further damage.

We install GAF Timberline HDZ, Owens Corning Duration, and CertainTeed Landmark. The three most popular architectural shingles in the country. All three are solid choices. GAF gives us access to the Golden Pledge warranty (25-year workmanship). Owens Corning Duration has SureNail technology for wind resistance. CertainTeed Landmark is a reliable mid-range option. We help you choose based on budget, color preference, and warranty goals.
