Professional Roof Replacement Services in New Hampshire

Every roof replacement is a major investment. Our team serves homeowners across southern New Hampshire with durable roofing systems designed for cold climates and heavy snow loads.

Asphalt shingles remain the top choice for most homeowners due to affordability and ease of installation. Architectural asphalt shingles and metal roofing perform exceptionally well in New England weather. Metal roofing installation is known for longevity and durability, and premium materials such as metal or slate may qualify for homeowner insurance discounts.

Choosing the right roofing material ensures durability, energy efficiency, and curb appeal.

Benefits of Roof Replacement With Solar in NH

Pairing solar with your roof replacement service creates long-term value for your home. Planning both systems together ensures proper installation and stronger performance.

Lower Energy Costs – Combining a new roof with solar improves efficiency and reduces reliance on traditional power sources. Many homeowners see meaningful savings over time while protecting their investment.
Stronger Foundation for Solar – A new roofing system provides proper structural support for solar panels. Replacing aging materials before solar installation reduces the risk of future disruptions.
Increased Property Value – Homes with a new roof and integrated solar often attract strong buyer interest. A professionally completed roof replacement enhances curb appeal and gives future buyers added confidence in the home’s condition.
Improved Longevity and Durability – Modern roofing materials improve ventilation and weather resistance. A properly installed roof replacement service protects against New England weather conditions for years to come.
Financing Opportunities – In many cases, roof and solar financing can be bundled into a single plan. Some homeowners find that the monthly payment aligns closely with their previous utility expenses.

Built for New Hampshire Weather

Replacing a roof in New Hampshire requires attention to local building practices. A self-adhering ice and water barrier must be installed along eaves and valleys to protect against ice dams. Proper attic ventilation prevents heat buildup in summer and reduces ice formation in winter.

During every project, we inspect the exposed wood deck for rot or damage and replace compromised plywood to ensure a stable base. A properly installed underlayment and flashing system protects against water migration and structural concerns.

We build roofs designed to stand up to harsh weather conditions.

Signs It May Be Time to Replace Your Roof

Recognizing early signs can help you avoid costly structural damage.

Age and Wear – Most homeowners should consider inspection once asphalt shingles reach 20 to 25 years of age.
Frequent Repairs – Repeated roof repair work often signals deeper roofing issues that replacement can resolve.
Granule Loss or Curling Shingles – Excess granules in gutters and visible deterioration indicate declining roofing material performance.
Structural Concerns – Sagging decking or soft spots suggest compromised structural integrity that may require full roof replacement.

Understanding Project Cost and Value

The cost of roof replacement depends on several factors including square foot measurement, roofing material selection, ventilation upgrades, and deck condition. Asphalt options are generally more affordable, while metal roofing or specialty materials increase project cost.

We provide clear proposals outlining materials, labor, and warranty coverage so you know what to expect. Our goal is transparent pricing and long-term value for your investment.

Our Roof Replacement Process

Our roof replacement service follows a structured process designed for quality and peace of mind.

Free Inspection and Consultation – A thorough inspection helps identify potential issues before they become costly. We assess shingles, flashing, gutters, attic ventilation, and decking condition.
Preparation and Protection – We protect siding, landscaping, windows, and yard areas before removing old roofing materials.
Removal and Deck Evaluation – Old shingles and underlayment are removed. We inspect the roof deck carefully and replace any damaged plywood to maintain structural integrity.
Installation of Underlayment and Ice Barrier – High-quality underlayment and ice and water shields are installed along vulnerable areas to prevent leaks caused by ice dams.
Shingle or Metal Installation – Asphalt shingles, slate, or metal roofing materials are installed according to manufacturer guidelines to ensure durability and long lasting performance.
Ventilation and Flashing – Proper attic ventilation and professionally installed flashing protect against moisture buildup and future leaks.
Final Inspection and Cleanup – A final inspection verifies workmanship and warranty standards. We perform a thorough cleanup, including magnetic nail sweep of the yard.

Every roofing project is completed with pride and attention to detail.

From getting the quote to having our roof completed, I was so impressed with every single person I interacted with at Sentry Roofing, specifically Drew, Caroline, Brett, and Dillon.

The day of the installation Dillon was sure to update me every step of the way, which was so helpful as I felt very informed. He even checked in a day after to see if I was satisfied, and to answer any questions.

Thank you to the entire team for making this as painless as possible! Our new roof looks fantastic compared to the old one!
