| Option | When it makes sense | What Nova provides |
|---|---|---|
| Replace before listing | Roof 20+ years, visible wear, competitive market. Removes the biggest inspection objection and lets you advertise a new roof with a transferable warranty. | Free inspection, Good/Better/Best estimate, install usually within 2–3 weeks, warranty transfer paperwork. |
| Credit at closing | Buyer wants to choose their own roofer, or timing is tight. | A written, itemized estimate the buyer's agent and lender will accept as the basis for the credit — so the number is real, not padded. |
| Disclose and price it in | Roof is 12–18 years and sound; you'd rather adjust the price than do the work. | A roof condition letter with photos and remaining-life estimate for the listing package. |
| Buyer-side opinion | You're the buyer and the inspection was vague. | A second opinion in writing before your contingency deadline. |
You have a contingency clock. We have a truck in Dover. Call, say you're an agent with a pending sale, and we'll schedule the inspection this week and deliver a written, itemized estimate within 48 hours — in the format buyers' agents and lenders expect.

Nova Roofing & Siding is a family-owned, GAF Certified roofing contractor based in Dover, NH, serving Strafford County, Rockingham County and York County, Maine.
“The only thing I can say after my experience working with Nova Roofing and Siding is unbelievable! They did the most professional and fast job and at very reasonable price. They stripped the old roof, applied 90 sheets of plywood and very professionally applied the new, top of the line roof all in one day.”
— RJ Lincoln, Google review“New roof looks amazing! The job was affordable and work was professional and timely.”
— Logan McColl, Google review“Nova Roofing made my roof replacement a breeze. Not to mention they have very fair pricing and great customer service. 10/10 will recommend to family and friends moving forward!”

*Nova's current pricing for asphalt architectural shingle systems in Seacoast NH and Southern Maine, updated September 2026: roughly $810–$925 per square (100 sq ft) installed, including tear-off of one layer. Add-ons: skylight flashing kits about $400 each, chimney flashing about $350, rotted decking replaced per sheet at cost plus labor. Metal standing-seam runs $1,200–$1,500 per square. Your instant estimate uses these same numbers; the fixed price comes after we walk the roof.
Manufacturer. Nova is a GAF Certified Contractor, which lets us register your roof for GAF's System Plus warranty when we install the full GAF system: 50-year non-prorated coverage on the materials, 15-year WindProven coverage with no maximum wind speed (named storms included), and 25-year StainGuard Plus algae coverage. GAF backs it, not us.
Workmanship. Nova puts a lifetime workmanship warranty in every roofing contract. If something we installed leaks because of how we installed it, we fix it. That's the one most contractors quietly cap at two years.
Financing is available through our lending partner on approved credit, with a soft credit check that doesn't affect your score. Fixed monthly payments; no prepayment penalty. We'll show you the payment on your estimate if you ask — and never push it if you don't.
Roughly 30 minutes from our Dover shop in every direction. Farther out, we take full roof replacements case by case — the ZIP check on this page tells you instantly.
If the roof is under 15 years and sound, no — disclose its age and move on. If it's 20+ years old or the inspection flags it, you'll either replace it, credit the buyer, or lose buyers to it. A new roof usually returns most of its cost in price and in fewer stalled deals; a credit usually costs you more than the roof would. We'll give you a written number for both conversations within 48 hours.
Get a roofer's written estimate within the inspection contingency window. Sellers typically choose between a credit at closing (based on the estimate), a price reduction, or replacing before closing with a transferable warranty. We turn estimates around in 48 hours for exactly this reason.
Yes. GAF's System Plus warranty transfers once to a subsequent owner (within the terms GAF sets), and our lifetime workmanship warranty transfers with the house. Both are selling points; we'll put them in writing.
Usually, yes. Most Seacoast roofs are one install day; the constraint is scheduling and permit timing, so call as early in the process as you can.
Yes. After a free inspection we provide a dated, signed condition report with photos and an estimated remaining life. Agents use it in the listing package to head off inspection surprises.
Call the number on this page and say you're an agent with a pending sale. Inspection-response estimates are turned around in 48 hours, and the report is written in the format lenders and buyers' agents expect.
An architectural asphalt roof installed correctly with ice & water shield and balanced ventilation typically lasts 25–30 years on the Seacoast. Three-tab shingles from the 1990s and 2000s are usually done at 18–22 years. Salt air, ice dams and north-facing moss all shorten that.
If the roof is under 15 years old with one problem area, repair. If it's 20+ years, has more than one leak, curling or missing granules across the whole slope, or a second layer, replacement is the better money — repairs on a tired roof are a subscription. Our inspection tells you which honestly; we do both.
Yes, by the sheet, at cost plus labor, and we photograph every sheet before it's replaced so you can see why.
Start with the ZIP. Inspection this week, written estimate in 48 hours, warranty that goes with the house.
