Roof Replacement
Full roof replacement starts with a complete tear-off down to the deck. We inspect every board for rot or soft spots. In Janesville, we find decking damage on about 30% of tear-offs. Damaged sections get replaced with CDX plywood before anything else goes on. Then we build up: ice and water shield in valleys and at eaves, synthetic underlayment across the full deck, new drip edge on every edge, starter strip, field shingles, hip and ridge caps, and ridge vent. Dumpster, permits, and cleanup included.

We repair asphalt shingle, metal, flat membrane, and tile roofs. Our trucks carry common repair materials so most fixes happen same-visit. Shingle repairs, flashing replacement, pipe boot swaps, ridge cap fixes, valley re-flashing. All routine for our Janesville crews.

Wind speeds above 60 mph cause shingle tab lift and adhesive seal failure per ASTM D7158 testing protocols. Our Janesville inspectors check the entire windward exposure. Not just the obvious damage. Poor ventilation causes ice dams which cause water intrusion under the shingle field during freeze-thaw cycles. We document all contributing factors so your insurance claim covers root-cause repairs, not just surface patches.

We install new roofs on new homes, additions, detached garages, carports, and covered patios. Material options include asphalt architectural shingles, metal standing seam, metal corrugated, and flat membrane systems. We help you choose based on your budget, aesthetic preference, and the specific demands of your Janesville climate.

Metal roofing reflects solar heat instead of absorbing it. In Iowa, that means 15-25% lower cooling costs compared to dark asphalt shingles. The higher upfront cost pays for itself over the life of the roof. And the life of a metal roof is twice or three times longer than shingles.

Architectural shingles are what we install on 90% of Janesville homes. They're thicker, heavier, and more wind-resistant than the old 3-tab flat shingles. They also look dramatically better. Dimensional profiles that mimic wood shake or slate. Standard architectural shingles carry a 30-year warranty. Premium versions go to 50.
Get a Free Quote →Flat Roofing
TPO single-ply membrane in 60-mil or 80-mil thickness, fully adhered or mechanically attached over minimum R-25 polyiso insulation. Hot-air welded seams tested with a probe at every joint. We install per NRCA and manufacturer specifications with tapered ISO insulation creating minimum 1/4" per foot positive drainage. Ponding water is the number one cause of flat roof failure in Janesville. Tapered insulation eliminates it. FM 4473 rated systems available for hail-prone areas. Fully warranted by Carlisle, Firestone, or GAF.

Your commercial roof has HVAC units, exhaust fans, plumbing vents, and satellite dishes punching through it. Every penetration is a potential leak point. We install prefabricated curbs, custom-welded flashings, and pitch pans that handle foot traffic and thermal cycling without failing.
