Wilco Exteriors provides roof replacement for homeowners in Janesville, WI, and throughout Southern Wisconsin and Northern Illinois. Curling shingles, a slow leak, or granules piling up in the gutter don’t always mean you need a full replacement, but they’re worth taking seriously. We install asphalt shingle and metal roofing systems built for Midwest storms, starting with a free roof inspection.
Stops Water Where It Starts
Once shingles crack or lift, water finds its way into the decking and insulation long before you see a stain on the ceiling. A properly installed roof keeps that moisture out at the source instead of buying time between repairs.
A Straightforward Installation
Our crew handles the inspection, material selection, tear-off, and cleanup directly, so you have one point of contact from start to finish instead of coordinating multiple companies.
Confidence In What's Overhead
A roof that’s aging or has been patched more than once is hard to stop thinking about. A full replacement means you know exactly what’s over your head instead of wondering before the next storm.
It's Not Just the Shingles That Keep Water Out
Shingles are what you see, but underlayment and flashing are what actually stop water from getting underneath them, especially around valleys, chimneys, and anywhere the roof has a seam. Wisconsin winters and Illinois storms put real pressure on all of it, not just the surface layer.
When we replace a roof, we look at the decking underneath, the flashing around every penetration, whether the soffit vents are letting enough air into the attic, and how water actually moves off the roof and into the gutters, not just which shingle color you picked. That’s what determines whether a roof holds up for the next twenty years or starts giving you trouble again in five.
How Much Life Does Your Roof Have Left?
Most homeowners don’t think about their roof until something goes wrong: a stain shows up on the ceiling, shingles start missing after a storm, or a repair doesn’t quite hold. By then, the damage is usually already spreading. Watch for:
Shingles that are missing, curling, or cracked, especially after a storm.
Granules collecting in the gutters, a sign the shingles are wearing thin.
Water stains on the ceiling or attic, even ones that seem to dry up on their own.
Sagging anywhere along the roofline, which usually means a structural issue underneath.
A roof that’s needed more than one or two repairs in the last few years.
If a few of these sound familiar, it’s worth having someone take a look. Wilco Exteriors has been helping homeowners across Southern Wisconsin and Northern Illinois with roof replacement for years.
