Our Services

Our Roofing Services

Professional Roofing solutions for residential and commercial properties in Alton.

roof replacement
FREE ESTIMATE

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

Not every problem needs a full replacement. Sometimes it's a blown-off shingle, a cracked pipe boot, or deteriorated valley flashing. We diagnose the actual issue and fix that. We don't upsell you into a new roof you don't need.

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 Alton inspector does a full 27-point inspection, free of charge.

new roof installation
TOP RATED

New Roof Installation

New construction roof installation following IRC Section R905 and local Alton building code amendments.

Metal Roofing

We do metal roof repairs too. Loose panels, failed sealant at transitions, rust spots on older galvanized. Not every metal issue needs a full replacement. Our Alton crew can usually fix it same-day.

shingle roofing
INSURED

We install asphalt shingles from every major manufacturer. GAF, Owens Corning, CertainTeed, Atlas, Tamko, Malarkey, IKO. Each has different warranty tiers and price points. We walk you through the comparison without pushing one brand.

flat roofing
FREE ESTIMATE

Flat Roofing

Flat roof leaks usually happen at penetrations, seams, or flashing details. We locate the source, repair it properly, and coat the surrounding area. If the membrane is shot, we'll recommend replacement. Not a band-aid.

commercial roofing
SAME-DAY

Commercial Roofing

Our Alton commercial crews handle everything from small retail strip centers to 50,000 sq ft warehouses. TPO, EPDM, modified bitumen, metal. We're certified installers for all major commercial membrane systems.

gutter installation
LICENSED

Gutter Installation

Gutters aren't glamorous, but they're protecting your foundation, your fascia, and your landscaping. We install seamless aluminum gutters custom-formed on-site from a roll of coil stock. No seams means no leaks.

TOP RATED

Roof Inspection

Roof inspections after a storm are free. Always. We document hail hits, wind damage, and any pre-existing issues so your insurance claim is accurate and complete.

emergency roof repair
GUARANTEED

Emergency Roof Repair

After we tarp and secure your roof, we document everything for insurance purposes. Photos, measurements, damage descriptions. Your adjuster gets a professional report, not a handwritten note.

skylight installation
INSURED

Skylight Installation

Tubular skylights bring light into tight spaces. Closets, laundry rooms, interior bathrooms. They use a reflective tube through the attic space, so they work even when the roof is far from the ceiling. Installed in a few hours.

Simple Process

How It Works

1

Free Roof Inspection

Our inspector walks the roof looking at shingle condition, flashing integrity, vent function, and signs of moisture underneath. 30-45 minutes for most Alton homes.

2

Written Estimate

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

Expert Installation

We build your roof the way manufacturers require for full warranty coverage. Every layer matters. Ice and water shield, synthetic underlayment, starter strip, field shingles, hip and ridge caps.

4

Quality Check

We register your GAF, Owens Corning, or CertainTeed warranty directly with the manufacturer so it's active from day one. Your workmanship warranty from us starts the same day.

"Got three quotes for a roof replacement. Alton Roofing & Maintenance was the middle price but the only one who actually got on the roof and showed me photos. Everyone else just eyeballed it from the driveway."

"Used Alton Roofing & Maintenance for a leak repair over our bathroom. Turned out to be a cracked pipe boot — $425 fix. Honest guys, could have told me I needed a new roof but they didn't."

★★★★★

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

FAQ

Frequently Asked Questions

Manufacturer warranties range from 30 years to lifetime depending on the shingle line. Our workmanship warranty covers our labor and installation for the term stated in your contract. The best combo is the GAF Golden Pledge: 50-year material plus 25-year workmanship. That's what being a Master Elite contractor gets you.

We recommend GAF, Owens Corning, or CertainTeed. And we're certified by all three, so the choice is yours. In Alton, the most popular pick is GAF Timberline HDZ in Weathered Wood or Charcoal. For hail-prone areas, look at the impact-resistant versions rated UL 2218 Class 4. We walk you through the options during the estimate.

We partner with GreenSky and Hearth for roofing financing. Options include 12-month same-as-cash (0% if paid in full within 12 months), 5-year fixed rate, and 7-10 year extended plans. Monthly payments on a $15,000 roof run about $150-$250/month depending on the term. Apply during the estimate.

Depends on size, pitch, and materials. Average in Alton 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) 349-1553.

Catch the water with a bucket, move valuables out of the drip zone, and call us at (877) 349-1553. 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 Alton and tarp the area to stop further damage.
