A roof problem is cheapest the day you find it, so book a free roof inspection in Mechanicsville and across Southern Maryland, call (301) 909-3383. One Vision Roofing is a family-owned, GAF Certified roofing contractor, licensed and insured under MHIC #151744. We inspect roofs across St. Mary’s, Calvert and Charles County from the roof and the attic, photograph everything we find, and give you the report whether you hire us or not.




After a storm. Wind and hail damage is often invisible from the ground and has a filing deadline attached. If that’s why you’re here, start with storm damage repair, the documentation matters for the claim.
Buying or selling a house. A roof is one of the first things a buyer’s inspector flags and one of the biggest line items in a negotiation. Knowing the roof’s real condition and remaining life before you’re at the table is worth having.
A stain, a drip or a smell. Anything showing up on a ceiling has already been in the roof assembly a while.
Every few years after year ten. Southern Maryland’s humidity, UV and wind age roofs faster than the warranty suggests. A roof that looks fine from the driveway can be several years past where you’d assume.
Before a warranty claim. Manufacturers ask for documentation. Ours is dated and photographed.
The inspection is free and so is the written estimate. No trip charge and no diagnostic fee, whether you hire us or not.
You keep everything we photograph. If you want a second opinion, you have the evidence to get one, which is the point.
We will tell you when the answer is nothing. A roof with years left in it is a finding too, and saying so costs us a quote and earns the next one.
We inspect the attic, not just the shingles. Most free inspections in this area are a walk around the yard and a sales pitch, and they stop at the roof surface, which is a problem, because decking and ventilation are where the expensive failures hide and neither is visible from up top. We also won’t manufacture urgency. If your roof has eight good years left, that’s what we’ll tell you and that’s what goes in writing, even though it means no job for us today. We’ve talked a lot of people out of roofs they didn’t need, and a fair number of them called us back when the roof was actually finished.
The report is yours to keep regardless, dated, slope by slope, and formatted so an insurance adjuster or a buyer’s agent can work from it directly. The person doing the inspecting is on the crew that would do the work, so you’re getting a read from a roofer rather than a commissioned closer with a tablet. We’re family owned and based in Mechanicsville, GAF Certified, insured and licensed under MHIC #151744, which you should check, on us or on anybody else you let up on your roof.
Neighbors watch a roof go on, then call. That is how this business has grown and it is why we will not cut a corner where somebody is watching, which is everywhere.
If you want to see what a finished job looks like before you pick up the phone, the gallery is full of real roofs across St. Mary’s, Calvert and Charles County.
Southern Maryland is home, not a territory we drive to. We are based in Mechanicsville and we work the tri county area every week, so a free inspection does not have to wait for us to be passing.
Yes. No trip charge, no diagnostic fee, and you keep the photos whether or not you hire us. The exception is a formal written roof certification for a real estate or lender requirement, which carries a fee, we’ll tell you up front if that’s what your situation calls for.
Usually forty-five minutes to an hour for an average home, including the attic. Larger or more complex roofs take longer.
It helps, because we’d rather walk you through the findings in person with the photos in front of you. If you can’t be there, we can do it by phone afterward and send the report.
Yes, in almost every case, a roof can’t be properly assessed from the ground. If the pitch is too steep or conditions make it unsafe, we’ll tell you and inspect it another way rather than risk damage or injury.
Photos of every slope and every finding, an honest read on remaining roof life, and a clear recommendation. If work is needed, an itemized written estimate with the photos attached.
No. We’ll tell you what the roof needs, which is sometimes nothing. If it needs a repair rather than a replacement, we’ll say so.
Yes, it’s dated, photographed slope by slope, and formatted the way adjusters work. For active storm damage, start on our storm damage repair page, since the claim process has its own steps.
Usually within a few days. If water is actively coming into the house, say so when you call and we’ll move you up.
If the inspection turns up a leak or isolated damage, that’s roof repair. If the roof has reached the end, roof replacement is the honest next step. If everything checks out and you want to keep it that way, a roof maintenance plan is the cheapest insurance on this list. And if wind or hail is what brought you here, storm damage repair covers the emergency work and the claim documentation.
Forty five minutes, both sides of the deck, and photos of everything we find. No charge and no obligation.
