Roofing in Sandown
Why Do Sandown Roofs Fail Where They Do?
Sandown homes sit in the woods. That means shaded north faces, moss along the eaves, ice that builds in the same spot every February, and pine branches that come through the shingles after a nor'easter.
We work the neighborhoods around Main Street, Angle Pond, and out toward the Hampstead and Danville town lines. Older properties out here have often been added onto more than once, and the seam where the addition meets the original house is where water tends to find its way in.
We look at the whole roof, not just the shingle. Decking condition, ice and water shield in the valleys and at the eaves, attic ventilation, flashing around chimneys and pipe boots, ridge caps, gutter pitch. The part of the roof you cannot see is usually the reason the part you can see is leaking.

Seamless aluminum, properly pitched and sized for the roof above them. Half the fascia rot we end up repairing started with a gutter that overflowed at one corner for five winters.

Steam removal. No chipping, no chunks taken out of your gutter. New England winters do this every year and we have been pulling ice dams off Sandown roofs every February for decades.

If the roof needs replacing, the siding around the rake and soffit usually needs attention too. Vinyl and fiber cement, plus repairs around new chimneys and dormers, done together so the trim lines match.

How Do You Choose a Roofer in Sandown, NH?
Before you hire anyone to work on your roof, run them through this list. Ask us the same questions.
- Do they regularly work in Sandown and the nearby border towns?
- Will they inspect decking, flashing, ventilation, and gutters, not just the visible shingles?
- Do they explain repair versus replacement with both options on the table?
- Are licensing, insurance, warranties, cleanup, and payment terms all in writing before work starts?
- Do they understand New England ice dams, storm damage, and fast weather changes?
- Can they show real local work or references from neighboring homes?
There is a longer version of this in our roofing contract checklist, which covers what to read in the paperwork before you sign with anyone.
How We Quote a Sandown Roof
Every roof is different. What moves your number is the square footage, the pitch, how many layers are coming off, the condition of the decking underneath, and how many valleys, chimneys, and skylights are in the way. Two houses on the same street can land thousands apart for reasons neither owner can see from the driveway.
So we do not publish prices online. The only honest number is the one written down after a foreman has walked the property. If you want to understand what actually drives the figure before we get there, we broke it down in what drives roof replacement cost in Southern NH.
What you can count on: the inspection is free, the quote is in writing before anyone starts, financing may be available, and the number you were quoted is the number you pay.

Sandown Roofing Questions
Do I need a full roof replacement, or can it be repaired?
If you have curling shingles across the whole roof, granules washing into the gutters, recurring leaks in more than one spot, or a roof past 20 years old, you are probably looking at a replacement. Single-area leaks, flashing failures, pipe boot replacements, and storm-damaged sections can usually be repaired. We inspect the decking and flashing before telling you which one it is. If a repair will buy you another five years, we will say so.
How long does a roof replacement take in Sandown, NH?
Most asphalt residential replacements are finished in one day. Larger homes, slate, or jobs where we have to pull damaged decking can run two to three days. You will know which one your house is at the estimate.
How does Merrimack Valley Roofing quote a roof in Sandown?
A foreman comes to the house, measures the roof line, checks the decking and flashing, and writes the estimate from what he saw. The number accounts for square footage, pitch, how many layers are coming off, decking condition, and the flashing work involved. You get it in writing before any work is scheduled. We do not quote sight unseen, because the only honest number is the one written for your specific roof.
Will the crew clean up after themselves?
Yes. Tarps cover the landscaping while we work. A magnet rolls the lawn for nails when we are done. The trailer leaves with the old roof. You should not be picking up debris the next morning, and nobody should be pulling nails out of the yard a week later.
What is the warranty on a new roof?
Materials carry a manufacturer-backed lifetime guarantee through GAF. Our materials and service are covered under a 14-year warranty. The paperwork is in your hands before we drive away, and we have been family-run in Sandown since 1976, so it is not a warranty from a company that disappears next spring.
Do you handle storm damage and insurance claims?
We document the damage with photos and a written assessment for your insurance carrier. The claim itself is between you and your insurer, but you will have the documentation you need to support it.
Do you offer financing?
Financing may be available. Terms get sorted at the estimate stage so there are no surprises later.
Are you licensed and insured?
Fully licensed and insured, carrying general liability and workers' compensation. Documentation is available on request before any work is scheduled.
Do you work in Sandown year round?
Yes. Asphalt shingles seal using heat from the sun, so in deep cold that seal takes longer to set and a winter install needs hand-sealing in the right spots. We work through the winter and we run ice and snow removal all season. We will also tell you when a repair will hold safely until spring instead.
