How much does roof replacement cost in Annandale, VA?
Cost depends on size, deck condition, shingle or TPO system, and flashing complexity. After measuring roof area, checking plywood, and inspecting attic ventilation, we provide a line-item estimate with material, labor, permits, and warranty included.
How long does a residential roof replacement take?
Most single-family homes take 1-2 days for tear-off to deck, synthetic underlayment, ice and water shield, new shingles, chimney flashing, and ridge vent with daily cleanup and magnetic sweep.
What is the difference between TPO and EPDM for flat roofs?
TPO is white reflective 60-mil membrane heat-welded at 1.5-inch seams for energy efficiency. EPDM is black 60-mil membrane with taped seams and ballast options. Both use ISO tapered insulation, coated metal edge, and walk pads at HVAC.
Do you handle emergency leak repair?
Yes, same-day tarp securing with batten fastening, leak source detection near skylights and valleys, step flashing and pipe boot replacement, and temporary seal to stop interior damage before permanent repair.
What warranties do you offer?
GAF Timberline HDZ shingles include up to 50-year material warranty, TPO/EPDM includes 15-20 year manufacturer warranty, plus our workmanship warranty. All registered after final walk-through with photo documentation.
Do you offer maintenance plans for commercial roofs?
Yes, we clean drains, check and probe seams, reseal pipe boots, clear debris, and provide photo reports with recommendations to extend roof life and keep warranty compliant for retail strips on Georgia Avenue.
How do I know if I need repair vs replacement?
If decking is solid, flashing is the issue, or leak is isolated at valley, pipe boot, or skylight, repair is enough. If shingles are curling, granule loss is heavy, or leaks are multiple, replacement with full tear-off to deck is more cost-effective.
Do you offer financing?
Yes, financing is available for qualified projects. We don't publish lenders, rates, or terms. Ask us about the options and we'll walk you through what's available and help you find a fit for your budget.
