Honest Roofing, Built in Wyandotte for Downriver
Guthix Roofing is a licensed roofing, siding and gutter contractor based in Wyandotte, Michigan, serving Downriver and metro Detroit. We started it to fix what frustrates homeowners most about this trade: vague pricing, pushy sales, and not knowing who's actually on your roof.
Roofing without the runaround
Replacing a roof is one of the biggest investments a homeowner makes — and for too many people it comes with a knot in the stomach: surprise charges, high-pressure sales, and a crew they've never met. Guthix Roofing exists to take that anxiety off the table.
We pair modern tools — instant satellite roof measurements and a free on-site inspection — with something refreshingly old-fashioned: a clear, itemized price and a straight answer. 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. You always know exactly what you're paying for and exactly who stands behind it.
Meet Greg Tittle, founder & owner
Guthix Roofing was founded by Greg Tittle, a Downriver local based in Wyandotte, after years working in the metro Detroit roofing trade. Greg started Guthix around a simple idea: homeowners deserve to see a real price without a salesman on their couch, and to know exactly who is accountable for the work on their roof.
When you work with Guthix, you deal with a small local team that Greg runs personally — not a call center, not a rotating cast of project managers. Greg sets every price, supervises every install, and is reachable from the first estimate to the final walkthrough. Guthix Roofing LLC is a Michigan-licensed residential builder (License #262600716, LARA Bureau of Construction Codes), fully insured, and a BBB Accredited Business, and an Owens Corning Preferred Contractor.
New company. Not a new roofer.
Guthix Roofing LLC was formed in March 2026 and started roofing in Wyandotte in July 2026. We'd rather say that plainly than dress it up. What you're hiring is the experience behind it — years of inspections, sales, and production on Downriver roofs — plus the paperwork that protects you: Michigan residential builder license #262600716, general liability insurance (certificate on request), BBB accreditation, Owens Corning Preferred Contractor status (which lets us register the Owens Corning System Protection Limited Warranty on a complete Owens Corning roof replacement), and a 10-year workmanship warranty in writing.

The standards behind every roof
These aren't slogans — they're the rules we hold every estimate, crew, and job to.
Total Transparency
An itemized estimate before any work begins, and an honest assessment even when the answer is "you don't need a new roof yet." No hidden costs, no upsell games.
Built to Last
Quality materials, proper ventilation and flashing, and full tear-off inspections — so your roof holds up to Michigan's freeze-thaw winters and summer storms for decades.
Treated Like Our Own
Clean worksites, respect for your property and time, and a real person who answers when you call. We're local — you'll see us again, and we like it that way.
Downriver First, Metro Detroit Beyond
Most of our work is within about 20 minutes of Wyandotte. Beyond Downriver we serve the rest of Wayne County and four more metro Detroit counties.
Downriver
Home base. Wyandotte, Southgate, Lincoln Park, Allen Park, Trenton, Taylor, Riverview, Grosse Ile, Ecorse and the rest of the river towns.
Wayne County
Detroit, Dearborn, Livonia, Canton, Westland & Downriver. Older housing stock and heavy snow loads — where proper tear-offs and ventilation matter most.
Oakland County
Royal Oak, Troy, Southfield, Novi & Farmington. A mix of historic and newer homes, all fighting the same freeze-thaw cycle.
Macomb County
Warren, Sterling Heights, Clinton Township, Roseville & St. Clair Shores. Dense post-war neighborhoods and Lake St. Clair winds put a premium on tight flashing and ventilation.
Washtenaw County
Ann Arbor, Ypsilanti, Saline, Dexter & Chelsea. Historic homes and heavy tree cover mean storm debris, moss, and limb damage we know how to handle.
Monroe County
Monroe, Bedford & Flat Rock. Wind exposure off Lake Erie makes secure shingle installation and solid flashing non-negotiable.
