SERVING GREENCASTLE, PARoofing Contractor in Greencastle, PA
Greencastle is the first Pennsylvania exit on our home interstate, and Antrim Township around it has become a genuine logistics corridor, distribution roofs by the acre alongside a borough square that predates the republic. We serve both from thirty minutes away. Call (540) 550-9703, answered 24 hours a day.

What Greencastle roofs actually face
Exit 5 changed Greencastle. The borough keeps its historic square and its neighborhoods, while the township around it fills with distribution centers, truck facilities, and the flat membrane roofs that come with them. That pairing, historic borough plus modern logistics, is unusual, and it happens to match our crew’s two strongest suits.
Membrane measured in acres
The distribution buildings around exit 5 carry TPO and EPDM at serious scale. We inspect, repair, coat, and replace low slope systems, and we write the reports facility managers actually file.
Borough buildings with age
Greencastle’s center square buildings carry the flashing and cornice detail of their era. Metal work and careful tear offs, done with respect for buildings older than the state’s roads.
Postwar and newer shingle
The neighborhoods around the square run standard residential stock, aging on schedule, priced honestly, installed to wind spec.
Vibration finds weak fastening
Buildings near the corridor live with constant heavy traffic vibration. Fastener back out shows up early here, and our inspections check for it specifically.
Permits and PA registration in Greencastle
Greencastle borough and Antrim Township permit separately, and commercial work in the township comes with the submittal package you would expect for buildings that size. Our Pennsylvania HICPA registration is active, our commercial documentation is thorough, and we file everything under our own credentials.

Borough or Antrim Township
Confirmed by parcel, filed with the right office, no guessing.
Commercial packages complete
Product data, fastening schedules, and warranty terms included up front, which is how commercial permits clear without stalling.
Programs over emergencies
For corridor facilities we set semiannual inspection and maintenance schedules, because a planned coating beats an unplanned tear off every time.
Roofing services available in Greencastle
Roof Replacement

Standing seam gauge and finish, thermal movement, and snow retention that earns its keep in a 30 PSF snow load town.

The right system for low slope rear additions and for the distribution buildings out by the I-70 and I-81 interchange.

Wind and hail damage documented with the storm date on it, from tarp to finished roof, without anyone touching your deductible.
Why Greencastle homeowners hire a Martinsburg crew
We will tell you exactly where we are
1886 Winchester Ave, Martinsburg, WV 25405. That is about 25 miles from Greencastle, straight up I-81, roughly a half hour without traffic. It is not a Greencastle address and we are not going to list one. A warranty call from Washington County is a short drive on the interstate, not a trip in from another region.
Licensed in Maryland, not just next door
Virginia, West Virginia, Maryland, Pennsylvania, and Florida. Maryland work means the Maryland Home Improvement Commission, which is a different regulator with a different insurance floor and a homeowner guaranty fund West Virginia does not have. Ask every roofer bidding your house for their MHIC number.
Family owned since 2016
Licensed, bonded, and insured. The scope is written before the ladder goes up, which Maryland requires anyway, so you can compare our estimate to anyone else’s line by line.

Roofing questions we get in Greencastle
- Do you handle large distribution center roofs?
Yes. Low slope membrane at commercial scale is a core service, from leak response to full replacement, with maintenance programs in between. Being thirty minutes away means response times facility managers can plan around.
- Are you registered to work in Pennsylvania?
Yes, HICPA registration through the Attorney General, current and printed on every Pennsylvania contract as the law requires.
- Can you also do my house in the borough?
Of course. Residential is half our week everywhere we work, and Greencastle’s neighborhoods are standard, honest shingle work we can often schedule within days.
From Greencastle we also serve State Line, Marion, and the corridor south toward Hagerstown and north toward Chambersburg.
