Get answers to common questions about roofing services in Alton, New Hampshire.
For a standard single-family home in Alton, a full asphalt shingle roof replacement typically ranges from $8,500 to $15,000. This range accounts for New Hampshire's higher material and labor costs, the complexity of your roof (like the steep pitches common in our area), and the need for high-quality, ice-and-water barrier underlayment due to our harsh winters. Always get 2-3 detailed, written estimates from local, licensed contractors for the most accurate pricing.
The ideal scheduling windows in Alton are late spring (May-June) and early fall (September-October). These periods typically offer the most stable, dry weather, which is crucial for proper installation. Summers can be busy with contractor backlogs, and late fall into winter brings unpredictable snow, ice, and cold temperatures that can compromise adhesive seals on shingles and create unsafe working conditions.
Absolutely. Given Alton's heavy snowfall, freeze-thaw cycles, and potential for ice dams, choosing the right material is critical. Asphalt architectural shingles with a high wind and impact rating, metal roofing (which sheds snow efficiently), and synthetic slate are excellent, durable choices. A proper installation must include a robust ice and water shield along the eaves and in valleys, and adequate attic ventilation to mitigate ice dam formation, which is a common local issue.
First, verify they are licensed to work in New Hampshire and carry both liability insurance and workers' compensation. Look for established local companies with physical addresses and strong references from other Alton or Lakes Region homeowners. They should be knowledgeable about local building codes, which may include specific requirements for snow load and ice dam protection. Always check their rating with the Better Business Bureau and review their portfolio of completed local projects.
Yes, a building permit from the Alton Town Offices is required for a full roof replacement to ensure the work meets the New Hampshire State Building and Fire Codes. Regarding weather, contractors must plan around the fast-changing conditions of the Lakes Region. Sudden thunderstorms, high winds off Lake Winnipesaukee, and early or late-season snow are real possibilities, so a flexible schedule and clear communication about weather delays from your contractor are essential.
