We find where the water actually gets in.
Licensed, insured, never subcontracted. We find the source, not just the stain on the ceiling tile.
A leak in a commercial building isn’t just a maintenance item, it’s product on the floor, a ceiling tile in the wrong place, and tenants or customers noticing. And because commercial roofs are large and flat, water travels far from where it gets in, which is exactly why leaks get chased and never quite fixed.
We find and stop commercial roof leaks. We trace water back to its real entry point, the failed flashing, open seam, or drainage problem behind it, and make a lasting repair, not a temporary patch that leaks again next month. We respond quickly, because on a commercial building the cost of a leak is measured in more than the repair.
We handle commercial roof leaks for property owners across Lansing, East Lansing, Okemos, St. Johns, Grand Ledge, Owosso, and the surrounding mid-Michigan communities, nine counties around our home base in St. Johns. Wherever you are in that area, you get the same thing: a licensed, insured, quality-vetted crew that never subcontracts, four manufacturer certifications behind the work, and a straight answer about what the building actually needs. That last part is the reason Andrew, Aaron, and Preston started Anchor in the first place.

Commercial Roof Leaks the way it should be done.
It starts with a free, no-obligation look at what’s actually going on. We don’t quote commercial roof leaks over the phone or from a photo. We come out, trace the water to its actual entry point, and give you an honest read on what it will take to stop it. If a smaller fix will hold, we’ll tell you that. If it won’t, we’ll show you why, with pictures, so the decision is yours to make on real information.
Then our own crew does the work. We never subcontract commercial roof leaks to a rotating cast of strangers, the people who quoted your job are the people on your property, which is how the details stay right from the first fastener to the final cleanup. As certified installers, we do the work to manufacturer spec, not the fast way, because that’s what makes it last and keeps your warranty intact.
And we build for Michigan. Snow load, ice, wind, and the freeze-thaw that punishes everything up here, we account for all of it in how we detail the work. When we’re done, we clean up after ourselves and walk you through what we did. You’re left with commercial roof leaks you can stop thinking about, which is the whole point.
We won’t take your money for work the building doesn’t need. That’s the reason this company exists.
Property owners choose us because we tell them the truth. We won’t take your money for work the building doesn’t need, and we won’t cut a corner you can’t see to win a job on price. That’s not a slogan. It’s why we’re certified by CertainTeed, LP SmartSide, James Hardie, and Lomanco, why we carry full licensing and insurance, and why so much of our work comes from people who were told straight and treated fairly. When you’re ready, the first step is simple: a free look, an honest read, and a fair price in writing.
Done the honest way.
We trace, not guess
On a big flat roof, water enters far from where it drips inside. We trace it to the real source so the repair actually stops the leak.
Fast response
A commercial leak costs more than a repair, it costs inventory, downtime, and reputation. We move quickly to stop the water.
A real fix
We repair the actual failure, flashing, seam, or drainage, not slap a patch over the drip that leaks again next storm.

Straight answers about commercial roof leaks.
No hedging. Here’s the plain version of what homeowners ask us most, and you can see finished work in our gallery.
Why is it so hard to find a commercial roof leak?
Because commercial roofs are large and flat, water enters at one point and travels a long way across and through the assembly before it drips inside, so the interior stain is rarely under the actual opening. Finding a commercial leak takes tracing the water back to its true source, which is the real skill in the work.
How fast can you respond to a commercial leak?
We prioritize active commercial leaks because the cost of waiting is high, inventory, equipment, downtime, and interior damage all add up fast. We move quickly to stop the water and protect the interior, then make the lasting repair.
Can you fix the leak without replacing the whole roof?
Usually, yes. Most commercial leaks come from a specific failure, flashing, a seam, a puncture, a drainage problem, that can be repaired without replacing the entire roof. We only recommend replacement when the roof has broadly failed, and we’ll show you why before we ever suggest it.
Why does my commercial roof leak keep coming back?
Because the real source was never fixed, a patch was put over the drip instead of over the actual entry point. Water travels, so patching the wrong spot just moves the leak. We trace it properly, which is why our repairs hold instead of reappearing after the next storm.
What causes most commercial roof leaks?
The usual culprits are failed flashing around rooftop units, curbs, and walls; open or split seams in the membrane; punctures; and drainage problems, including ponding water and clogged drains. The field of the membrane leaks far less often than these detail points.
Do you offer maintenance to prevent leaks?
Yes. Regular inspections and maintenance catch small flashing, seam, and drainage problems before they become leaks that disrupt your business. For commercial buildings it’s one of the highest-return investments you can make in the roof.
