Roofing and siding work in Corunna, Michigan by Anchor Siding LLC

Good bones, done to spec.

The houses around the courthouse square in Corunna were built well the first time. Full-dimension framing, real decking, the kind of construction you can’t buy new anymore. Our job on a house like that is to not undo it. So we work to manufacturer spec rather than to whatever’s fastest, and we carry the certifications that define that spec: CertainTeed on shingles, LP SmartSide and James Hardie on siding, Lomanco on ventilation. Four certifications, and every one of them exists because there is a right way to lap an underlayment, set a step flashing, and balance intake against exhaust.

That last one gets skipped more than anything else in this county. A roof with no intake air cooks itself from underneath, and the shingles fail years early while everyone blames the shingles. We check the attic before we quote a Corunna roof, every time, because there’s no point putting a good roof over a bad ventilation problem.

Shiawassee County winters are the other half of the equation. Snow that piles and stays, ice damming along the eaves, hard wind, and a freeze-thaw cycle that works fasteners loose a fraction at a time over years. Everything we install is specified for those loads, not for a milder climate somebody’s catalog was written in.

None of that means much if you can’t trust the person telling you about it, which is why Andrew, Aaron, and Preston set this company up the way they did. We tell you what your house actually needs, full stop, including when the answer is “less than you were expecting” or “nothing yet.” The first visit is free and carries no obligation: we get on the roof, photograph what we find, walk you through it, and put a real scope and a fair price in writing. Repair when a repair will hold. Replacement only when it’s earned. Then our own crew, never a subcontractor, does the work, and we’re licensed and insured behind it. We clean the site down to running a magnet over the drive before we leave.

Whether it’s metal or shingle roofing, roof repair, a full re-side, storm and hail restoration with the insurance claim handled, gutters, or commercial work in town, each job has its own page below. They’re genuinely different trades and we keep them separate. Or call and describe the problem and we’ll tell you which one it is.

Three things we don’t compromise on.

The same three rules hold on every job we take, in every town we work. They are the reason neighbors pass our name along.

i.

We never subcontract

Every Corunna job is our own crew, the people who quote your work are the people on your roof. That’s how the details stay right from the first fastener to the final cleanup, and it’s why the quality never depends on who a subcontractor sent that day.

ii.

Honest, no upsell

If a repair will hold, we’ll tell you. We don’t take Corunna homeowners’ money for work their home doesn’t need, that’s the reason we started, and it’s why so much of our work here comes from referrals rather than a hard sell.

iii.

Certified & insured

CertainTeed, LP SmartSide, James Hardie, and Lomanco certified, fully licensed and insured, using premium materials built for Michigan winters, installed to manufacturer spec, in the details that decide whether the work lasts. That certification is your assurance the work is done right and the warranty stays intact.
