Built for this climate

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.

Where most of our installs happen

New home construction

Complete shingle roofs for new houses, from one custom home to a small subdivision, scheduled around your builder's framing and inspections.
01

Room additions and dormers

Where a new roof meets an old one is where leaks love to start. We weave or close the valley, step-flash the wall and lap ice-and-water shield well past the seam so the tie-in stays dry.
02

Garages, barns and sheds

No one lives under a detached garage or workshop, but it still needs proper underlayment, drip edge and airflow to protect what you store inside.
03

Porches and low-slope roofs

Sections flatter than a 2:12 pitch get a membrane roof instead of shingles, installed and flashed to tie cleanly into the main roof.
04

Attic ventilation

Ridge vents, soffit intake, gable and box vents, calculated from the attic's square footage so the new roof breathes from day one.
For contractors

We work to your build calendar

Sequencing set before we start, dry-in dates kept, our own insurance certificate before mobilization, and per-unit pricing on multi-lot jobs where the crew stays on site.

Local roof installers

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.

Why builders call us back

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.

FAQ

Questions about new roof installation.

Working with a general contractor? We will talk to them directly.

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.

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.

Yes. We file it in St. Mary’s, Calvert or Charles County, the cost is in your quote, and we set up the inspections.

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.

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.

Related services

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.
