Roofing Contractor in Concord, NH
Concord is a mix of eras. There are 19th century homes near downtown with steep slopes and multiple dormers, mid-century ranches in the Heights, newer construction off Route 106, and mill-era buildings in Penacook that have been patched and re-patched for a century. No single roofing approach fits all of them.
Sentry Roofing & Solar has spent more than 25 years working on New Hampshire exteriors, and that experience shows up in how we look at a roof. We check flashing details and attic ventilation before we talk about shingle brands. We tell homeowners when a repair makes more sense than a replacement. Because we install and service solar as well as roofing, we can also tell you how a roof will hold up under panels ten or fifteen years from now instead of guessing.
More than 170 five-star reviews and a lifetime workmanship warranty on our roofing installations stand behind that work.
- Lifetime Workmanship Warranty
- Discounts for Both Roofing and Solar

Roofing Services We Provide in Concord
Roof inspections. A detailed look at shingles, flashing, valleys, penetrations, ventilation, and the attic side of the deck. You get photos and a plain explanation of what we found, including what can wait.
Roof repair. Leaks around chimneys and skylights, wind-lifted shingles, failed pipe boots, damaged valley metal, ice dam damage, and gutter problems that push water back under the eaves. Small repairs handled early are usually the difference between a modest bill and a project involving sheathing, insulation, and interior finishes.
Roof replacement. We remove the old roofing down to the deck, inspect and repair the sheathing, install ice and water shield in the vulnerable areas, integrate step and counter flashing properly, and balance intake and exhaust ventilation. Covering problems over is how roofs fail early.
Metal roofing. Standing seam and metal panel systems for homeowners who want long lasting protection and better snow shedding on steep pitches. Metal also solves porch roofs, additions, and low-slope sections where asphalt struggles. Modern profiles include designs that read closer to slate or shake than to a barn roof.
Commercial roofing. Flat and low-slope systems for Concord businesses, including membrane repairs, drainage corrections, roof coating for aging low-slope surfaces, and scheduled maintenance that keeps small failures from spreading across a large roof area.
Roof cleaning and maintenance. Moss and algae hold moisture against shingles and shorten their service life, particularly on shaded north-facing slopes. Careful cleaning protects the roofing materials underneath and restores the appearance of the home’s exterior.
Ventilation and gutters. Ridge vents, soffit intake, bath and kitchen exhaust routed correctly, and gutters and downspouts sized for the roof they serve.
Storm damage assessment. After wind and hail events we inspect the roof and can assist with documentation, including photographs and written findings homeowners can provide to their insurance carrier. The claim itself stays between you and your insurer.
Roof compatibility assessments for solar. An evaluation of remaining shingle life, deck condition, framing, pitch, orientation, and shading before panels go on.
Roofing Problems We See Most Often Around Concord
Ice dams top the list. New Hampshire’s weather produces the freeze and thaw pattern that builds ice at the eaves, and the cause is almost always heat escaping into the attic paired with too little intake ventilation. A heat cable treats the symptom. Correcting insulation and airflow addresses the reason the ice formed at all.
Flashing failure is the next most common source of leaks we find, especially on older Concord homes with brick chimneys, several roof-to-wall transitions, or additions built decades apart. Sealant was never meant to be the primary defense at those joints, and once it dries out water finds the gap.
We also see undersized ventilation on homes that were re-roofed quickly in the past, premature granule loss on slopes that stay damp, and three-tab shingles from the early 2000s reaching the end of a service life that harsh weather conditions here tend to shorten.
Roofing Systems and Materials We Install
Asphalt shingles remain the most popular choice for residential roofing, and for good reason. Architectural shingles offer solid durability, a wide color range, strong wind ratings, and a reasonable cost per square. They carry a manufacturer warranty on the materials themselves, which works alongside our workmanship warranty on the installation.
Metal roofing costs more upfront and typically lasts decades longer. It sheds snow readily, resists ice damage at the eaves, and holds its finish well. It also requires a crew that understands snow retention above entries, walkways, and driveways, which is where inexperienced metal installations cause trouble.
For low-slope and commercial roofing, we work with membrane systems and coatings selected for the drainage, foot traffic, and equipment on that particular roof.
We help you compare options on your own home rather than steering every project toward the same product. Pitch, exposure, framing, budget, how long you plan to stay, and whether solar is in the picture all change the right answer.
Roofing and Solar Under One Company
Most roofing companies stop at the roof deck. We do not, and that changes what we can tell you.
If you are considering solar, we assess whether your roof can support a system that will run 25 years or longer. Installing panels on a roof with eight years left in it creates an expensive removal and reinstallation project down the road. If replacement makes sense first, we sequence both so the work happens once.
If you already have panels and need repairs underneath, one team removes the array, corrects the roofing, and reinstalls the system. There is no dispute between two contractors about who owns the leak.
Qualified roofing projects and solar can often be combined into a single financing plan. For homeowners who need a new roof and want the energy savings solar provides, that frequently makes the full project workable in one step instead of two.
Ventilation, insulation, and reflective roofing choices also affect energy efficiency, and we talk through those details during the inspection rather than treating them as upgrades to sell later.
Why Concord Homeowners Choose the Roofing Experts at Sentry
Experience that predates the trend cycle. Twenty-five years of exterior construction across New Hampshire, on residential and commercial buildings.
Honest recommendations. If your roof has good years left, we say so and tell you what to watch. We would rather earn the replacement in five years than push it today.
Real local presence. We are here, we answer the phone after the job is finished, and we still service roofs we installed a long time ago.
Written scope and clear timelines. Materials, work included, ventilation details, payment schedule tied to project milestones, and a realistic schedule window, all in writing before anything starts.
Insured, with documentation available on request. Verifying coverage is a reasonable thing to ask any contractor, and we make it easy.
A lifetime workmanship warranty on roofing. Installation defects are our responsibility, not yours.
How to Evaluate a Roofing Contractor in New Hampshire
New Hampshire does not issue a statewide roofing contractor license, which puts more weight on what you verify yourself. A few things worth checking with any reputable contractor you consider:
Ask for proof of liability and workers compensation insurance, and confirm it directly with the carrier rather than accepting a certificate at face value.
Ask who pulls permits and schedules municipal inspections. That should be handled by the contractor as part of the project.
Ask for a detailed written estimate covering scope, material specifications, and payment schedule. A one-line price is not an estimate.
Ask for recent local references. Past customers will tell you about responsiveness and quality faster than a brochure will.
Be cautious with pressure to sign the same day, large payments requested upfront, and bids that come in far below everyone else. Unusually low numbers often mean corner-cutting, or repairs that get added once the old roof comes off.
We are glad to answer all of those questions about our own company.
What to Expect on Your Project
1. Inspection. We walk the roof when conditions allow, get into the attic, and photograph what we find.
2. Explanation. We show you the photos, describe the condition in language that makes sense, and separate urgent items from maintenance items.
3. Written estimate. Firm pricing and scope. If more than one approach is reasonable, such as architectural asphalt versus standing seam metal, we price both and explain the trade-offs.
4. Scheduling and permits. We handle permitting, give you a realistic window, and tell you when weather moves a date.
5. Installation. Property and landscaping protection, tear-off, deck inspection and repair, then installation to manufacturer specification.
6. Walkthrough and cleanup. We review the finished work with you, clean the site thoroughly, and register your warranty coverage.
Frequently Asked Questions
How much does a new roof cost in Concord, NH?
Cost depends on square footage, pitch, the number of layers to remove, deck condition, valleys and penetrations, and material choice. A straightforward asphalt replacement on a ranch sits in a very different range than a steep Victorian with dormers and a metal system. We provide firm written pricing after an inspection rather than guessing over the phone.
Do I need roof repair or replacement?
Age and pattern tell us most of what we need to know. An isolated leak on a twelve-year-old roof with sound shingles is usually a repair. Widespread granule loss, curling across multiple slopes, or repeated leaks in different areas point toward replacement. You get an honest read either way.
Is metal roofing worth it in New Hampshire?
Often, yes. Metal handles snow load and ice at the eaves well, lasts substantially longer than asphalt, and needs very little maintenance. The upfront cost is higher, and installation details matter more, particularly snow retention over doorways and walkways.
How long does a roof replacement take?
Most residential replacements in the Concord area finish in one to three days. Complex rooflines, deck repairs, or solar removal and reinstallation add time, and we tell you what to expect before we start.
Can you inspect my roof before I install solar?
Yes, and we recommend it. A roof compatibility assessment tells you whether the roof will outlast the system and whether the structure, pitch, and sun exposure support the production you are expecting.
Do you help with storm damage claims?
We can assist with documentation. That includes inspecting the roof, photographing damage, and providing written findings you can submit to your insurance company.
What areas do you serve near Concord?
We work throughout the Concord area, including Penacook, East Concord, Boscawen, Bow, Hopkinton, Pembroke, Loudon, and Canterbury, along with much of central and southern New Hampshire and northern Massachusetts.
