St. Mary's County MD Roofing & Exterior Contractor Serving Pax River, Leonardtown & the 235 Corridor.

Services We Offer Across St. Mary's County, MD

St. Mary's County housing stock concentrates around the Pax River workforce belt — Lexington Park, California, and Great Mills colonials, the Three Notch corridor housing pool, and the Leonardtown historic district. We install all six exterior trades with the same one-crew standard from our St. Leonard shop, and federal-workforce-grade specs are the baseline on Pax River households.

Roofing

JDH is an Owens Corning Platinum Preferred Contractor installing complete architectural shingle systems with Class 4 impact-rated SureNail tech as the default post-storm spec. St. Mary's County housing concentrates around the Pax River workforce belt in Lexington Park and California, and the 1960s-1970s Three Notch corridor pool runs a different replacement cycle than the post-2000 colonials adjacent to Naval Air Station Patuxent River.

Gutters

Custom seamless K-style aluminum gutter networks with engineered foundation-drainage routing; copper option for premium and historic-district parcels.

We size every drop to the actual roof surface area, not a generic rule.

Insulation

Owens Corning attic insulation and air sealing. R-49 minimum for Maryland code. Older Lexington Park and Great Mills homes from the 1940s-1960s Pax buildout were built to R-19 or less; an upgrade typically pays back in 3-5 years on cooling cost alone.

What's Different About St. Mary's County Homes

St. Mary's County is Maryland's three-river peninsula: Patuxent on the northeast, Chesapeake Bay on the east, Potomac on the southwest, Wicomico on the west, with the St. Mary's River cutting through the interior. Founded in 1637, anchored by NAS Patuxent River, and stitched together by MD-235 from Charlotte Hall to the Pax gate. Housing stock here runs from tobacco-era farmhouses still standing in Bushwood and Loveville to 1940s WWII Pax buildout ranches in Lexington Park to the 2000s MD-235 corridor subdivision wave. Three things define the work here:

HAAG Master Certified

St. Mary's County Storm Documentation, Done Right

Hail and wind damage in St. Mary's County almost always requires a written Xactimate scope of loss with photo documentation before an insurance adjuster will approve coverage. May 22, 2025 hail hit Lexington Park, Great Mills, California, and Leonardtown hard. The Isaias 2020 tornado touched down on MD-5 just south of Leonardtown, dropping 9 inches of rain at Sotterley. Isabel 2003 effectively rebuilt St. George Island. JDH writes the document in the format adjusters expect, photographs every area of damage at the angle that proves it, and can walk the inspection with your adjuster on the day they show up. If your St Marys County, MD home took a hit during a recent event, same-day storm damage roof response across our service area moves you to the front of the schedule.
