Windows
JDH features ProVia Certified window installers specializing in energy-efficient Endure series vinyl replacements with Energy Star packages.

Window services →Doors
JDH provides ProVia Certified entry door installations using heavy-duty fiberglass and steel storm systems with corrosion-resistant hardware. Storm-rated entry doors with stainless hardware fit Port Republic's bayfront housing pool where Scientists' Cliffs covenant-aware spec plus salt-air corrosion specs run a tight 10-year replacement floor.

Door services →Gutters
Custom seamless K-style aluminum gutter networks with engineered foundation-drainage routing; copper option for premium and historic-district parcels. Port Republic's bay-side tree canopy plus the Scientists' Cliffs and Kenwood Beach bayfront parcels run different downspout calculations than inland Calvert tracts. We size every drop to the actual roof surface area, not a generic rule.
Gutter services →Insulation & Cert
JDH holds Owens Corning Top of the House Certification for advanced attic insulation and code-compliant air sealing to R-49 Maryland standard. Most pre-2000 Port Republic homes including the Scientists' Cliffs covenant pool were spec'd to R-19 or less, and the upgrade pays back in 4 to 6 Calvert summer cooling cycles for the Chesapeake bay-side homeowner pool. Includes VA, FHA, and HUD pre-sale roof certifications.

Port Republic, MD is an unincorporated community in mid-south Calvert County, 5 miles south of Prince Frederick and 8 minutes north of JDH headquarters in St Leonard, organized at the crossroads of MD-2 / MD-4, MD-264 (Broomes Island Road), MD-509, MD-765, and Parkers Creek Road. ZIP 20676 covers a unique pool of communities you do not find anywhere else in the JDH service area: Scientists' Cliffs (the 1935 wooden-exterior covenant community on the Chesapeake Bay), Kenwood Beach and Governors' Run on the Bay-side, Western Shores, and the Christ Episcopal Church / Calvert County Jousting Tournament corridor along MD-264. Three things define how we work this CDP:
Port Republic Housing Eras — One Roof Approach Won’t Fit
Port Republic housing pool runs Scientists’ Cliffs 1935 wooden-exterior covenant homes, Kenwood Beach and Governors’ Run bayfront cottages, Western Shores Bay-side parcels, and the MD-264 / Broomes Island Road historic corridor. Each era used different decking, framing, and shingle standards. A one-size roof quote misses what your specific home actually needs.
Home Crew · 8 Minutes North
Most Port Republic roofing contractors drive in from out-of-area chains and outer-market crews. JDH is 8 minutes north on MD-2 / MD-4 (same Calvert County), with our crews, our trucks, and our warranty office close enough that a Tuesday-morning inspection becomes a Tuesday-afternoon quote.
Bay-Side Salt-Air + Calvert Cliffs / Cove Point Federal Market
Port Republic sits under bay-side salt-air corridor with Scientists’ Cliffs covenant-aware preservation spec requirements. Calvert Cliffs Nuclear Power Plant workforce and Dominion Cove Point LNG engineer pool drives a deep PCS-cycle-aware homeowner pool that expects defensible spec and resale-ready warranty paperwork on every install.
Why Port Republic MD Homeowners Choose JDH
JDH Remodeling has served Maryland homeowners since 1986 and works Port Republic neighborhoods including Western Shores, Kenwood Beach, Governors every week. None of the few Port Republic roofing companies stack HAAG Master plus Owens Corning Platinum plus James Hardie Elite plus ProVia Platinum credentials. Port Republic homeowners keep finding us despite our shop being east in St Leonard.
Three Generations · Family-Owned Since 1986
Founded in 1986 by Jim Dodson Sr., who built the company on federal-grade construction at the Pentagon and U.S. State Department. Three generations of Dodsons have served Maryland and Virginia homeowners through every major storm season since, from Hurricane Isabel in 2003 through the September 2024 EF-1 tornado. Jim Dodson runs operations today as a HAAG Master Certified Inspector, and the third generation, J.J., is age 4. Read Our Story: Three Generations of Dodsons in the Trades.
Proven Performance Across the Port Republic Community
514 completed structural jobs across Port Republic and the surrounding area, including Western Shores, Kenwood Beach, Governors. Owens Corning Duration installs across Estate Gray, Driftwood, Pacific Wave, Midnight Plum, and Colonial Slate color codes are in place on neighboring streets right now. Multiple State Farm, USAA, Liberty Mutual, and Allstate carrier-tagged completions sit beside the uncredentialed alternatives that have thinner local track records, and JDH crews are in your Port Republic neighborhood weekly so any homeowner can verify a recent install firsthand.
Committed to the Community We Live In
Out-of-state storm chasers roll into Southern MD after every major weather event, sign quick contracts, and disappear once the insurance checks clear. National conglomerates send faceless crews who never set foot in Port Republic again. JDH lives in the same towns you do, drives the same roads daily, and raises kids in the schools your neighbors use. Our HAAG Master Certified credential #992109047 is engineering expertise we use to protect actual neighbors from getting shortchanged by multi-billion-dollar insurance carriers.
Fixed Pricing, Written Before Tear-Off
Our written estimate is the final contract price you pay. The first four sheets of replacement OSB decking are included at no charge, fully insulating you from mid-project surprises if rot turns up under your shingles. We assume the structural risk; you assume none of it. That is the entire reason we hold a 4.9-star average across 1,400-plus reviews and why Port Republic homeowners trust us with the kind of one-shot capital decision the next 30 years rest on.

What Our Port Republic MD Customers Say
Three representative examples from Port Republic, MD homeowners. See all 1,400+ reviews on Google.
"JDH replaced the roof on our Calvert family-home colonial right before we listed. HAAG inspection on a Monday, install finished Thursday, listing photos Friday. The Estate Gray color matched our neighbor's roof exactly and the realtor said it was the best comp on the street."
"Dual-commuter household. My wife works DC, I work Pax River. JDH scheduled a Saturday install so neither of us had to burn a weekday off. Roof and gutters done in one visit. Quote was the final price. Couldn't have asked for a smoother process."
"State Farm claim after a wind event in Port Republic. JDH walked the adjuster through the damage with their HAAG documentation, claim approved in two weeks. Colonial Slate Owens Corning Duration installed cleanly in two days. Best contractor experience I've had."
