Roof installation company in Mechanicsville, MD.
Southern Maryland roofs take hot, humid summers, nor’easters, tropical storm remnants and the odd January ice storm. A new roof here has to be built for all of it from the first day, not upgraded later after the first leak.
We install complete roof systems on new homes, additions, garages and outbuildings throughout Mechanicsville, St. Mary’s County and the rest of Southern Maryland, whether you are near Golden Beach, Charlotte Hall or tucked off Three Notch Road. You deal with one local, family-owned crew from plans to final inspection, with honest guidance and no runaround.
We are GAF Certified and a Military Trusted Partner. That means factory-trained installers, a manufacturer spec someone else checks, and a company that treats your home and your schedule with respect.

Why builders and homeowners choose us for new roofs.
We are not a national chain or a franchise. You will know our names, and the same faces show up from the first measurement to the final walk-through. As a local, family-owned roofer, we know what Southern Maryland weather does to a roof, so we specify what works here instead of a one-size-fits-all package.
Why GAF Certified matters on a new roof
Our installers are factory trained by GAF, so the whole system works together: deck protection, leak barrier, starter strip, architectural shingles and ridge cap. That certification also lets us register GAF’s manufacturer warranties on your new roof.
Fully licensed under MHIC #151744 and insured, we hand your lender, county inspector and insurance agent the paperwork they need the first time they ask.

Dry-in dates we actually keep.
For a builder, the roof schedule is half the job. Getting the house dried in on the date we promised keeps the trades behind us working, and it is why general contractors call us for the next lot instead of the lowest bidder. We also nail the details that disappear once siding goes up: kick-out flashing at each wall, ice-and-water shield lapped past every addition seam, and ventilation calculated for the attic instead of copied from another plan.
Homeowners building new get the same treatment. One crew and one contact, with no dispatcher in the middle and no rotating subcontractors on your lot. GAF warranties are registered in your name, and our office is right here in Mechanicsville if a question comes up years later.

Questions about new roof installation.
Do you install roofs for builders and general contractors?
Yes, all the time. We agree on sequencing, keep the dry-in date and carry our own insurance with a certificate ready before we mobilize. Ask us about per-unit pricing on multi-lot projects.
How long does it take to install a roof on a new house?
Most single-family homes take one to two days once the crew is on site. Complicated rooflines or steep pitches may need a third. Dry-in comes first, so the framing is protected right away.
Will you handle the roofing permit?
Yes. We file it in St. Mary’s, Calvert or Charles County, the cost is in your quote, and we set up the inspections.
Can you roof an addition and tie it into my existing roof?
Yes, without tearing up the old roof. We step-flash and kick-out flash the connection and lap ice-and-water shield well beyond the seam. If your current shingle is discontinued, you see the nearest match before we place the order.
What kind of ventilation goes on a new roof?
Usually balanced ridge exhaust and soffit intake, sized to your attic’s square footage, unless the design calls for something different. We walk you through what is specified and why before the install.

Already have a roof that is worn out? That is roof replacement, not a new install. A new build is also the best time to have gutters and downspouts and soffits and fascia planned with the roof as one system, and our siding crew can close in the walls. Once you move in, a yearly roof maintenance visit keeps the new roof in top shape.
