Full Roof Replacement in Northern Virginia, DC & Maryland
Complete tear-off and rebuild using GAF, Owens Corning, or CertainTeed architectural shingles — permits pulled, decking inspected, ice-and-water shield upgraded to current code.
Most Northern Virginia roofs hit the end of their useful life between 20 and 30 years after installation — sooner on three-tab shingles installed in the 1990s, later on premium architectural shingles installed in the 2000s. King's Roofing replaces 200+ DC-metro roofs each year using the industry's top-rated systems (GAF Timberline HDZ, Owens Corning Duration, CertainTeed Landmark). Every replacement includes a written 10-year workmanship warranty on top of the 50-year limited material warranty.
What a Full Roof Replacement Actually Includes
Many homeowners hear three different scopes from three different contractors and can't tell what's actually different. Here's our standard scope so you have a benchmark:
(1) Complete tear-off of existing shingles, underlayment, and damaged flashing — never a layover. (2) Inspection of all decking; rotted or soft OSB is replaced at a flat $80/sheet (not a hidden upcharge). (3) Ice-and-water shield along all eaves, valleys, and around all penetrations — code-required in our climate but routinely skipped on bargain bids. (4) Synthetic underlayment across the entire field — not the legacy 15-lb felt that wrinkles and tears. (5) New aluminum drip edge on all eaves and rakes. (6) New step- and counter-flashing at every wall and chimney intersection (re-using old flashing is the #1 source of post-replacement leaks). (7) New pipe boots, new ridge vent, new ridge caps. (8) Magnetic nail sweep of the entire yard, driveway, and street. (9) Final-day walk-through with you.
Roof Replacement Cost in Northern Virginia & DC Metro
Pricing varies with roof complexity, material choice, decking condition, and your local jurisdiction's permit fee. As a 2025 benchmark for a typical 2,400 sq ft Northern Virginia Colonial:
- Architectural asphalt shingles (30-yr): $11,500–$15,500 installed
- Premium architectural (50-yr, Class 4 impact-rated): $14,500–$19,000 installed
- Composite/synthetic shake: $24,000–$36,000 installed
- Standing-seam metal: $28,000–$46,000 installed
- Natural slate or synthetic slate: $30,000–$60,000+ installed
We provide a written, itemized estimate at no charge — no high-pressure sales pitch, no same-day-only pricing, no fake 'rebate' theatrics. The price you see is the price you pay barring documented decking replacement at the rate disclosed up front.
Timeline: How Long Does a Roof Replacement Take?
Most single-family homes in the DC metro complete in one to two working days once material is staged. Day 1: tear-off, decking inspection, ice-and-water shield, underlayment, drip edge, starter course, and field shingles on the smaller slopes. Day 2: field shingles on remaining slopes, ridge vent, ridge caps, pipe boots, final flashing, cleanup. Larger estates (4,000+ sq ft) or steep multi-plane Victorians take three to four days.
From signed contract to install day is typically 2–4 weeks during summer, often 7–10 days in shoulder seasons. We do not install in active rain — your roof is never left open overnight.
Permits & Code Compliance
Every jurisdiction we work in (Fairfax City, Fairfax County, Arlington, Alexandria, Loudoun, Prince William, Montgomery County MD, Prince George's County MD, and DC) requires a permit for full tear-off replacements. We pull the permit, schedule the post-install inspection, and you receive the final inspection card for your records. Permit fees range $150–$425 and are included in our written quote — never billed as an extra later.
Manufacturer Warranties & Our Workmanship Warranty
King's Roofing carries GAF Master Elite certification (top 2% of GAF contractors nationally) and Owens Corning Preferred Contractor status. That means we can register your shingles under the manufacturer's extended Golden Pledge or Platinum warranties — 50 years material plus 25 years workmanship backed by the manufacturer, in addition to our own 10-year company workmanship warranty.
If we leave for any reason, the manufacturer warranty stays with the house — which is not true of every roofer's company warranty. We've been in business since 2010 and operate from the same Fairfax address; our company warranty has the same likelihood of being honored 10 years out as anyone's in this market.
