Full Roof Replacement – A roof is not “just shingles.” It’s a weather-sealed system.
When that system reaches the end of its life or fails in key areas full replacement becomes the most reliable, code-compliant, and cost-effective path for homes in southern New Hampshire and the MA border towns.
What “Full Roof Replacement” Actually Means
A full replacement (often called a “tear-off and install”) removes the existing roofing down to the deck and builds a new, warrantied system on top. In New England climate, that system typically includes:
- Decking: Inspection of plywood/boards; damaged areas replaced.
- Ice & Water Shield: Self-adhered membrane at eaves (ice dam zone), valleys, and penetrations—critical for NH winters.
- Synthetic Underlayment: Secondary water barrier across the field.
- Drip Edge & Starter: Edge protection and a straight, sealed shingle start.
- Flashing: Chimneys, walls/sidewalls, step flashing, counter-flashing, vent flashings.
- Ventilation: Balanced intake and exhaust (often ridge vent + soffit), sized to code.
- Shingles: Architectural asphalt (most common), or upgraded systems (impact-resistant, metal accents).
- Fasteners & Sealants: Manufacturer-approved nails and compatible sealants.
- Final Cleanup & Warranty Registration: Magnet sweep, debris removal, system warranty activation.
Repair vs. Replacement: How to Decide in NH
Choose replacement when one or more of these are true:
- Age: Most architectural asphalt roofs in NH last ~18–25 years, shorter if ventilation is poor or storms were severe.
- Widespread Failures: Curling, cracking, bald spots/granule loss across large areas.
- Multiple Leaks: Repeated leak history or chronic ice-dam issues.
- Decking/Attic Red Flags: Soft spots, rot, mold, or persistent moisture.
- Storm or Hail Damage: Systemic shingle bruising, torn tabs, or compromised seal strips.
- Code & Insurance Alignment: Ice barrier, ventilation, and flashing upgrades are due and make a partial fix uneconomical.
If damage is localized and the roof is fairly young, a targeted repair can still make sense. But once the “system” is compromised, replacement delivers durability, warranty coverage, and peace of mind.
Step by Step of Our New England Proof Process
- Evaluation & Photos: Roof, attic, ventilation, and flashing mapped with clear evidence.
- Plan & Permits: Scope, materials, ventilation math, and local requirements by town.
- Protection: Landscape tarps, plywood at eaves, safe debris chutes.
- Tear-Off: Full remove to deck; proper disposal (including any second layers).
- Deck Repair: Replace compromised sheathing; re-nail to code.
- Weatherproofing: Ice & water shield in eaves/valleys/penetrations; synthetic underlayment on the field.
- Metalwork: Drip edge, starter, new step/chimney flashings; counter-flashing as needed.
- Ventilation: Ridge vent cut-in (if applicable), intake confirmed, baffles where required.
- Shingle Installation: Architectural shingles installed to manufacturer spec and wind rating.
- Detailing: Pipe boots, skylight curbs, wall tie-ins, sealants.
- Cleanup: Magnet sweep, gutters cleared, yard left spotless.
- Quality Control + Registration: Final walkthrough, photo set, and system warranty submission.
Materials That Stand Up to NH Winters
- Architectural Asphalt Shingles with high wind ratings (up to 130 mph) and strong nail-strip technology.
- Premium Ice & Water Shield at eaves (extending inside warm wall line), valleys, and all penetrations.
- High-Grip Synthetic Underlayment for safer install and better long-term protection than felt.
- Aluminum/Copper Flashing correctly stepped and counter-flashed at walls and chimneys.
- Balanced Ventilation (ridge vent + soffits) to reduce ice dams, extend shingle life, and protect the deck.
- Optional Upgrades: Impact-resistant shingles, metal accent roofs (porches, bays), and integrated gutter systems.
2025 Reality Check – What It Costs in Southern NH & the MA Border
Every home is different. Roof area (in “squares,” where 1 square = 100 sq ft), pitch, stories, dormers, skylights, and ventilation needs all matter. Below are typical ranges for architectural asphalt on straightforward roofs in our service area:
| Home Size (typical roof area) | Common Range* |
|---|---|
| Small (12–16 squares; ~1,200–1,600 sq ft) | $9,000 – $15,500 |
| Medium (17–22 squares; ~1,700–2,200 sq ft) | $14,500 – $23,500 |
| Large (23–30 squares; ~2,300–3,000 sq ft) | $20,000 – $34,000+ |
*Ranges reflect 1 layer tear-off, standard complexity, architectural shingles, proper ice barrier, synthetic underlayment, new flashing where needed, and balanced ridge/soffit ventilation. Steep/complex roofs, multiple layers, extensive decking repairs, skylights/chimney rebuilds, and winter conditions can increase investment.
Timeline: most single-family homes finish in 1–3 working days, weather-dependent.
FAQs for New Hampshire Homeowners
Can you replace a roof in winter?
Yes—when temperatures and conditions allow and materials are handled per manufacturer guidelines. Ice & water shield adhesion and safety protocols become even more critical.
Will my yard be protected?
We stage protection before tear-off (landscape tarps, plywood at eaves) and use magnet sweeps to capture nails after.
What about permits and inspections?
Town-by-town requirements vary. We handle paperwork, meet code (including ice barrier), and coordinate inspections where required.
Is attic ventilation really that important?
In our climate, absolutely. Correct intake/exhaust helps prevent ice dams, preserves shingles, and can lower attic moisture.
Insurance claim for storm damage?
If damage qualifies, we document, provide scope clarity, and coordinate with your adjuster to keep the process transparent.
