Who Is Merrimack Valley Roofing?

Merrimack Valley Roofing is a family-run New Hampshire roofing company based in Sandown, working across Southern New Hampshire since 1976. Our crews are GAF Master Elite certified, the top tier of GAF's installer program, and we carry a BBB A+ accreditation. We handle residential and commercial roof replacement, roof repair, seamless aluminum and copper gutters, siding, and ice and snow removal. Every new roof we install is backed by a manufacturer-backed lifetime guarantee and a 14-year materials and service warranty. We are fully licensed and insured, and we answer emergency calls for leaks and storm damage 24 hours a day.

50 Years on New Hampshire Roofs

Fifty years is a long time to keep showing up in the same towns. We started roofing the Merrimack Valley in 1976, and we have spent every winter since then learning what a New Hampshire roof actually goes through. The ice that builds at the eaves in February. The wind that lifts shingles off in a March storm. The old layers a 1970s house is hiding under the current roof.

That experience is the whole point of hiring local New Hampshire roofers instead of a crew that rolled into the state after the last big storm. We are based here, we are licensed and insured here, and the same company that does your roof this year is the one you call when you need it looked at down the road.

How Fast Can You Get a Roofer Out in New Hampshire?

We answer the phone 24 hours a day for active leaks and storm damage. An ice dam in February and a wind event in March do not wait for business hours, and the water coming through a bedroom ceiling does not either. One repeat customer called us about wind damage and had the roof fixed less than 24 hours later. That is the pace we work at on emergency calls.

What Happens on an Emergency Call

The first job is finding where the water actually enters. It is often several feet uphill from the stain you can see, up at a valley, a chimney flashing, or a lifted shingle. We trace it, stop the water, and protect what is exposed. Then we talk through whether the roof needs a targeted repair or whether the age and condition make a replacement the better use of your money. If a repair will hold, we say so.

Winter calls run a little differently. Ice dams form when heat escaping the attic melts snow that refreezes at the cold eave, and chipping at that ice with the wrong tools puts holes in the roof underneath. We take it off safely and then look at what caused it.

New Hampshire Roofing Materials

Different roofs call for different materials. Here is what we install, and a foreman will walk you through which one fits your house and your budget on the estimate.

Asphalt Shingle

The workhorse of New England pitched roofs. Low maintenance, plenty of color and style options, and a sensible cost for most homes. This is what most of our residential roofs are built with.

Rubber

A durable, long-lasting flat-roof system used most often on commercial buildings and low-slope sections. Fire and UV resistant, and built for cost-effective protection.

Slate

A premium, long-lived material that can hold up for decades and adds real character to the right home. Available in a range of colors and textures.

Metal

One of the strongest systems out there and a strong match for snow country. Sheds snow and ice, stands up to harsh weather, and is energy efficient.

Every New Roof Comes With a Manufacturer-Backed Lifetime Guarantee

Plus a 14-year materials and service warranty, and 24/7 emergency response when a leak or storm damage cannot wait until morning.

How Do You Quote a New Hampshire Roof?

Every roof is different. The price depends on the size and pitch of the roof, the material you choose, how many old layers have to come off, and how easy the house is to work around. Two homes on the same street can land in very different places.

That is why we do not publish prices online. The only honest number is the one written down after a foreman has walked the property in person. Here is what you can count on:

  • A free, in-person estimate at your home.
  • A written quote before any work starts.
  • A foreman who walks you through the material options for your house.
  • Financing options if you want to spread the cost out.

New Hampshire Roofing Questions

Does my roof need a repair or a full replacement?

It usually comes down to age and how widespread the problem is. One leak around a chimney on a twelve-year-old roof is a flashing repair. Curling shingles across the whole south face of a twenty-five-year-old roof is a replacement, because you would be paying twice to fix it piece by piece. A sagging roofline or soft sheathing underfoot points to replacement as well. We come out, get up on the roof, and tell you which one you are looking at. If a repair will hold, we say so.

How long does a roof replacement take?

Most typical New Hampshire homes are a one-day job. We tear off the old roof, install the new one, and clean up the yard before we leave. Bigger or more complex roofs and commercial buildings can take longer, and we will give you a real timeline on the estimate so you are not guessing.

Do you offer emergency roof repair in New Hampshire?

Yes. We answer emergency calls 24 hours a day, 7 days a week for active leaks and storm damage across Southern New Hampshire and the Seacoast. If water is getting into the house, call us and we will get out to find the source and stop it from getting worse. Winter ice dam calls run through the same line.

How does Merrimack Valley Roofing quote a roof?

A foreman comes to the house, measures the roof, and gives you a written estimate. We do not publish prices online because the only honest number is the one based on your actual roof, your material choice, and how many old layers have to come off. The on-site estimate is free, and financing is available if you want to spread the cost out.

What roofing materials do you install?

Asphalt shingle, rubber, slate, and metal. Asphalt is the most common choice for New Hampshire homes. Rubber and metal are common on flat and commercial roofs, and slate is a premium option for the right house. A foreman will walk you through which fits your roof and your budget.

Do you handle both residential and commercial roofing?

Yes. We do residential roofs on homes across Southern New Hampshire and commercial roofs on businesses and larger buildings, including flat and low-slope rubber and metal systems. Same company, same crews, sized to the building.

What warranty comes with a new roof?

Every new roof we install is backed by a manufacturer-backed lifetime guarantee, plus a 14-year materials and service warranty. As a GAF Master Elite installer, we are able to offer warranty coverage that most contractors cannot.

Which New Hampshire towns do you serve?

We work across Southern New Hampshire and the Seacoast from our base in Sandown. That covers Salem, Derry, Plaistow, Kingston, East Kingston, Atkinson, Hampstead, Danville, Newton, and Brentwood inland, plus Portsmouth, Hampton, Exeter, Stratham, and Seabrook on the coast. We also take work out toward Manchester and Concord. If your town is not on the list, call and ask.
