Our Services

Our Roofing Services

Professional Roofing solutions for residential and commercial properties in Harmon.

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

new roof installation
TOP RATED

New Roof Installation

Atlas Pinnacle Pristine shingles with Scotchgard algae protection. Ideal for Illinois humidity. We also install Tamko Heritage laminated shingles for budget-conscious builds and Malarkey Vista AR with Flexor SBS polymer-modified asphalt for high-wind zones. Your installer should match your material choice to your climate, not just your budget.

metal roofing
GUARANTEED

Metal Roofing

Metal roofing in Illinois 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

Asphalt shingle roofing is the most common and cost-effective roofing system in Harmon. Our crews install 15-20 shingle roofs a month. We know the product inside and out. Nailing patterns, exposure measurements, hip and ridge details.

FREE ESTIMATE

Flat Roofing

Commercial flat roof replacement in Harmon starts with a core sample to check the existing insulation. If it's waterlogged, everything comes off. If it's dry, we can sometimes overlay. Saves you $2-$4 per square foot.

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

Improperly sized gutters cause fascia board rot and foundation erosion. We calculate gutter capacity using the rainfall intensity formula: roof square footage x pitch factor x rainfall rate (inches/hr for Harmon). Standard 5" K-style handles 5,520 sq ft of effective roof area. Bigger roofs or steeper pitches need 6" gutters with 3x4" downspouts. We hang with hidden hangers screwed into rafter tails every 24".

Roof Inspection

Buying a home in Harmon? Get an independent roof inspection before you close. Home inspectors look at the roof from the ground with binoculars. We get on it. Big difference.

emergency roof repair
GUARANTEED

Emergency Roof Repair

Most emergency roof repairs in Harmon are storm-related. High winds rip off ridge caps and shingles. Fallen limbs puncture the decking. We respond fast, tarp the damage, and coordinate the permanent fix. Including insurance paperwork if applicable.

skylight installation
INSURED

Skylight Installation

A skylight installed wrong will leak. The flashing has to integrate with the shingle courses. Step flashing on the sides, headwall flashing on top, and a sill pan underneath. We use manufacturer flashing kits because they're engineered to work with the skylight frame.

Simple Process

How It Works

1

Free Roof Inspection

We climb up, walk the entire roof, and document what we find with photos and measurements. Takes about 30 minutes. You'll see exactly what we see.

2

Detailed Quote

You get a written proposal with material specs, labor breakdown, timeline, and total cost. The number on the quote is the number you pay. No change orders, no hidden fees.

3

Roof Goes On

Our crews average 8 years of experience each. They tear off the old roof, inspect the decking, replace any damaged boards, and install your new system from the deck up.

4

Final Walkthrough

We walk the property with you, show you the finished roof, answer any questions. Then we run the magnetic nail sweep and clean up every scrap of debris.

What Our Customers Say

★★★★★ 4.9/5 from 476+ reviews
★★★★★

"Our insurance company tried to lowball us on the storm claim. Harmon 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. Harmon Roofing & Maintenance said I only needed valley flashing repair and some shingle replacement. Saved me about $14,000. I trust these guys."

"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."

FAQ

Frequently Asked Questions

Common signs: curling or cracking shingles, missing shingles after wind events, granule loss (look in your gutters), daylight visible through the attic, sagging roof deck, and age. Most asphalt roofs last 20-30 years in Illinois. If you see any of these, call (877) 349-1553 for a free inspection. We'll be honest about whether you need a replacement or just a repair.

Call (877) 349-1553 immediately. While you wait, put containers under any drips and move furniture and electronics away from the affected area. Take photos of the damage for insurance. Our Harmon crew will tarp the leak source and schedule a permanent repair. Most emergency calls get same-day or next-day response.

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 Illinois.

Most residential roofs in Harmon are done in one day. We show up at 7 AM, tear off the old roof, install the new system, and clean up by end of day. Two-story homes, steep pitches, or large roofs might take two days. We never leave a house uncovered overnight.

You get two warranties: one from the manufacturer on the materials and one from us on the workmanship. As a GAF Master Elite contractor, we can offer the Golden Pledge. That's 25 years on workmanship plus 50 years on the shingle. Owens Corning and CertainTeed have similar programs. Our own workmanship warranty is in writing and covers installation defects.
