Roof Replacement, Repair & Gutters in Wyandotte and Downriver
Guthix Roofing is a licensed roofing, siding and gutter contractor based in Wyandotte, Michigan. Most of our work is within ten miles of home — the Downriver communities below — with the rest of Wayne County and metro Detroit beyond that.
Real eyes on your home — before small problems get expensive
Most roof problems can't be seen from the ground. Michigan's freeze-thaw cycles, wind, and ice quietly work on your shingles, flashing, and seals every year — and by the time a stain shows up on your ceiling, the damage above it is already done.
A licensed pro, actually on your roof
Not a drive-by, not a guess from the street — we get up there and inspect shingles, flashing, vents, seals, gutters, and siding up close.
Photos of everything we find
You see exactly what we see — good or bad — so you're never taking a stranger's word for what's up there.
A straight recommendation
Repair it, replace it, or leave it alone. If your roof has years of life left, we'll tell you that too — and you'll have it in writing.
Storm damage documented for insurance
If weather did the damage, we photograph and document it properly and help you navigate the claim so nothing legitimate gets missed.
Trusted craftsmanship and total peace of mind
Unlike competitors, we lead with transparency: we start with a free on-site inspection, document what we find with photos, and put every line item in writing — so you get an accurate assessment and a fair price with zero surprises.
10-year Guthix workmanship warranty plus the Owens Corning limited lifetime shingle warranty — both in writing before you sign. Greg, the owner, sets every price and supervises every job; inspections are done by Greg or a member of his small local team, and installation is by a vetted local crew that works under Guthix's license, insurance, and warranty. Projects stay on schedule even with Michigan's unpredictable weather, and the person who quoted your roof is the person responsible for it.

Answers for Downriver homeowners
We believe in transparent communication. Here are answers to the questions we hear most — and we're always happy to talk through yours.
A licensed local pro gets on your roof and checks shingles, flashing, vents, seals, and gutters up close. We photograph what we find and walk you through it in plain English, with a straight recommendation: repair it, replace it, or leave it alone. It takes about 30–45 minutes, it's completely free, and there's no obligation.
Most Downriver homes run $6,800 to $11,500 for a full tear-off and replacement with Owens Corning Duration architectural shingles; larger two-story colonials run about $12,600 to $17,900. A second layer of old shingles adds $800 to $1,100 to strip. Type your address into our instant quote and you'll see your own range in about a minute — before we ask for your name — and every number is itemized in writing at the free inspection.
Architectural asphalt shingles are the most popular choice for Michigan homes — a strong balance of durability, value, and resistance to freeze-thaw cycles, snow, and wind. We install Owens Corning Duration® shingles, plus an impact-resistant Duration® FLEX upgrade for added protection against hail and high winds. We'll walk you through the choices and help you pick what's right for your home and budget.
Most residential roof replacements are completed in one to three days, depending on the size and complexity of your roof and the weather. Greg, the owner, sets every price and supervises every job; inspections are done by Greg or a member of his small local team, and installation is by a vetted local crew that works under Guthix's license, insurance, and warranty. The crew keeps a clean worksite and finishes with a full walkthrough.
