FREE ESTIMATE

Owens Corning Duration shingles with SureNail technology rated to ASTM D3462 and D7158 Class H wind resistance. Our Jamestown crews install TruDefinition Duration in a full Owens Corning system.

roof repair
SAME-DAY

Roof Repair

Missing shingles, cracked flashing, a leak over the kitchen. Whatever it is, we fix it. Our Jamestown repair crew runs 6 days a week. Most repairs take half a day.

storm damage repair
LICENSED

Storm Damage Repair

Wind speeds over 60 mph cause shingle tab lift and seal failure. Hail over 1" diameter causes fractures through the shingle mat to the fiberglass reinforcement. Our HAAG-trained inspectors know the difference between cosmetic damage and functional damage. That distinction determines your insurance payout.

new roof installation
TOP RATED

New Roof Installation

New construction roof installation following IRC Section R905 and local Jamestown building code amendments. We calculate ventilation per IRC R806 (1:150 ratio reduced to 1:300 when 50% is within 3ft of ridge. Synthetic underlayment per ASTM D226, ice barrier per ASTM D1970 at eaves in freeze-thaw climate zones. Manufacturer-certified installation locks in the full system warranty.

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

Architectural shingles are what 80% of Jamestown homeowners choose. They look better than 3-tab, last longer, and handle wind better. We install GAF Timberline, Owens Corning Duration, and CertainTeed Landmark.

flat roofing
FREE ESTIMATE

Flat Roofing

TPO single-ply membrane in 60-mil or 80-mil thickness, hot-air welded seams, fully adhered or mechanically attached over polyiso insulation board. We install per NRCA and manufacturer specifications. Ponding water is the number one cause of flat roof failure. We use tapered ISO insulation to create minimum 1/4" per foot slope to drains. FM 4473 rated systems available for hail-prone Jamestown areas.

commercial roofing
SAME-DAY

Commercial Roofing

Roof coatings can extend the life of your commercial roof by 10-15 years for a fraction of replacement cost. We apply silicone and acrylic coatings over existing TPO, EPDM, and metal substrates. Not every roof qualifies. We'll be straight with you.

gutter installation
LICENSED

Gutter Installation

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

roof inspection
TOP RATED

Roof Inspection

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.

emergency roof repair
GUARANTEED

Emergency Roof Repair

Emergency roof repairs for active water intrusion follow a strict protocol: tarping with reinforced polyethylene sheeting secured to the roof deck, interior water extraction guidance, and temporary flashing at penetrations. Our Jamestown emergency crews carry 20x30 tarps, 2x4 nailer boards, and masonry anchors for various deck types. Permanent repairs are scheduled within 48-72 hours once materials are sourced.

skylight installation
INSURED

Skylight Installation

Skylights bring natural light into rooms that don't have it. Bathrooms, hallways, closets. We install VELUX and Fakro fixed and vented skylights with proper flashing kits designed for asphalt shingle roofs.

"We were quoted $18,500 for a 32-square replacement with Timberline HDZ. They hit the number exactly. No change orders, no surprise fees. That's rare in this business."

"Our insurance company tried to lowball us on the storm claim. Jamestown Roofing & Maintenance supplemented the estimate and got it approved for $7,000 more. They know the Xactimate system better than the adjuster did."

"Asked for a second opinion because another company said I needed a full replacement. Jamestown 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

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.

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.

Absolutely. Our team includes HAAG Certified Inspectors who document storm damage the way insurance adjusters expect. We file the claim, meet the adjuster, handle supplements if the initial estimate is low, and complete the repairs. We work with every major carrier in California.

Most residential roof replacements in Jamestown cost between $8,500 and $24,000. The price depends on your roof size (measured in squares, where 1 square = 100 sq ft), pitch, accessibility, and material choice. Architectural shingles are $350-$550 per square installed. We give free estimates with exact pricing.

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 Jamestown and tarp the area to stop further damage.
