Complete Roof Replacement — Done Right the First Time
When repairs aren't enough, trust Maryland and Delaware's top-rated team for a full roof replacement with premium materials and lifetime warranty coverage.
Maryland & Delaware's Trusted Roof Replacement Specialists
A roof replacement pays dividends for decades — but only if it is done correctly the first time. After 1,600+ completed projects across Anne Arundel, Prince George's, Montgomery, Howard, Sussex, Kent, and New Castle counties, we have refined a replacement process that protects your property, your warranty rights, and your homeowners insurance policy. Our standard install is a complete tear-off to bare decking — never a layover, never a shortcut. Every layer of old material comes off so we can inspect, repair, and rebuild the system from the deck up.
We are GAF Master Elite certified — held by fewer than 2% of US roofers — and a Tamko Pro installer. That credential matters because it unlocks the GAF Golden Pledge warranty: 25 years of labor + materials + tear-off coverage and 50 years on the shingle itself, manufacturer-backed.
Signs You Need a Roof Replacement
- Curling, cupping, or clawing shingles — granules have worn off and the asphalt mat below is failing.
- Excessive granule loss in gutters and downspouts — UV has burned through the protective top layer.
- Dark streaks from algae on north-facing slopes and visible bald spots.
- Separated or rusted flashing at chimneys, skylights, and walls.
- Multiple existing layers — code in most MD and DE counties prohibits a third layer.
- Age past 18-25 years for architectural shingles or 15-20 years for older three-tabs.
- Insurance non-renewal letter — major MD and DE carriers are dropping homeowners with aging roofs.
Our Replacement Process
Full tear-off down to bare decking, board-by-board inspection, replacement of any soft or rotted sheathing at cost, new ice & water shield in valleys and along eaves (Maryland code: 24" past the warm wall), synthetic underlayment over the entire deck, premium architectural shingles installed in the manufacturer's specified high-wind nailing pattern, new step flashing at every wall and chimney, and balanced Cobra ridge ventilation. We protect your property with tarps over landscaping and pool, use magnetic catchers in the lawn for every dropped nail, and conduct a full magnetic sweep of your driveway before we leave.
Premium Materials Only — No Builder-Grade Shingles
We exclusively install Tamko Titan XT and GAF Timberline HDZ architectural shingles — engineered with heavier fiberglass mats, advanced adhesive systems, algae-resistant granules, and wind resistance up to 160 mph (Tamko Titan XT in the high-wind pattern). For homeowners wanting a more dimensional look, GAF Camelot II designer shingles deliver a slate-and-cedar aesthetic with the same lifetime warranty profile.

Roof Replacement in Maryland & Delaware — What Local Homeowners Should Know
Mid-Atlantic re-roofs face a punishing combination of stressors that generic install advice rarely accounts for: 95°F+ summer humidity, sub-20°F winter snaps, hurricane-remnant winds off the Chesapeake, and the freeze-thaw cycle that finds every unsealed nail head.
Code Requirements
Maryland follows the IRC with state amendments — ice & water shield on the lower 24" past the warm wall, synthetic underlayment over the entire deck, step flashing (not roofing cement) at every wall intersection. Anne Arundel, Howard, Montgomery, and Prince George's counties all require permits and post-install inspection. Delaware is permit-required statewide; Sussex County additionally requires hurricane-rated nailing patterns within 10 miles of the coast.
Climate Stressors by Region
Coastal DE & MD Eastern Shore: hurricane-remnant winds — we recommend 160 mph rated Tamko Titan XT with stainless ring-shank nails. Western MD: ice damming and hail — Class 4 impact-resistant shingles plus extended ice & water shield. Inland MD: heat and UV — light-color algae-resistant shingles with proper ridge ventilation.
