Quality You Can Trust

Local & Reliable

5-Star Service

What's Included in Each Exterior Service

Every estimate from Nova breaks down exactly what's part of the scope, so you know what you're paying for before any work starts. Here's how we approach the four services we install most across New Hampshire and Southern Maine.

Roof Replacement

A complete roof system, not just shingles

A typical Nova roof replacement is a full system review, not just a shingle swap. New England's freeze-thaw cycles, ice dams, and snow load punish shortcuts. Every install is reviewed for the details that actually keep water and weather out.

  • Architectural or designer GAF shingles
  • Ice & water shield in vulnerable zones
  • Decking inspection & replacement as needed
  • Attic ventilation review
  • Step, valley & chimney flashing
  • Magnetic-sweep cleanup before we leave

Siding Replacement

Vinyl or LP SmartSide, installed right

New siding refreshes your home's curb appeal and seals out moisture, but most siding problems trace back to install shortcuts (poor flashing, missed house wrap, sloppy trim returns). Our scope addresses what's under the panels, not just what shows.

  • Vinyl & LP SmartSide engineered wood options
  • Full house wrap inspection & replacement
  • Window & door flashing detail work
  • Soffit, fascia, and trim refresh as needed
  • Color matching for accents and detail bands

Replacement Windows

Custom-fit to your existing openings

New windows quiet down rooms, drop your heating and cooling bills, and lift the look of your whole exterior. Each window is custom-measured for its opening, no off-the-rack guesses, no oversized trim to hide bad cuts.

  • Double-hung, casement, slider, and bay/bow styles
  • Energy-efficient Low-E glass options
  • Custom measurement for every opening
  • Interior trim restoration after install
  • Coordinate with siding projects for one install window

Seamless Gutters

Custom-formed on-site, properly pitched

Gutters keep water away from your foundation, but only if they're properly pitched, securely attached, and big enough for New England's rain and snow runoff. Our seamless aluminum gutters are custom-formed on-site so leak points are dramatically reduced.

  • 5" and 6" seamless aluminum, custom-formed on-site
  • Color-matched to your trim or siding
  • Hidden hangers (no exposed spikes) for clean look
  • Optional gutter guards to reduce maintenance
  • Proper downspout routing away from foundation

Frequently Asked Questions

What's the difference between the two estimate options?

The Instant Estimate uses satellite imagery to measure your roof or siding in real time, so you see a price range in about two minutes without anyone visiting. It's the right path if you're researching pricing. The Technician Call path is better for windows, gutters, or any combination of services, a project manager reaches out the same day to schedule a free on-site walkthrough.

Is the estimate really free?

Yes. Both estimate paths are free, with no obligation and no high-pressure sales pitch. Whether you hire Nova afterward is entirely up to you.

Where does Nova Roofing & Siding serve?

Nova serves homeowners across New Hampshire and Southern Maine, including Dover, Portsmouth, Rochester, Somersworth, Durham, Exeter, Hampton, Stratham, Manchester, Concord, Nashua, Kittery, York, Berwick, Sanford, Portland, and surrounding towns. See the full locations list above.

How much does a new roof cost in New Hampshire?

Roof replacement pricing in NH varies based on square footage, pitch, number of existing layers, decking condition, ventilation needs, and material selection (architectural vs designer shingles). Most asphalt shingle replacements on a typical single-family home in New Hampshire fall in a broad range, use the Instant Estimate to see a satellite-measured price range for your specific roof.

How long does a roof replacement take?

Most single-family asphalt shingle roof replacements are completed in 1–3 days, weather permitting. Larger or more complex roofs (multiple stories, complex valleys, decking replacement, slate or metal materials) can take longer.

Can I bundle multiple services in one project?

Yes, and bundling usually saves money. Combining a roof replacement with new gutters, or a siding project with window replacement, generally reduces combined labor versus running each as a separate job. Use the Technician Call path for bundled scopes.

Do you offer financing?

Yes. Nova partners with Enhancify to offer flexible financing options for qualifying homeowners across roofing, siding, windows, and gutter projects. Financing is provided through approved third-party lenders and is subject to credit approval. We'll walk through what fits during your estimate, with no pressure to use it.

Are you licensed and insured?

Yes. Nova Roofing & Siding is fully licensed and insured in both New Hampshire and Maine, GAF certified for roofing installation, and BBB accredited.

What's the best siding material for New England winters?

Both vinyl siding and LP SmartSide engineered wood perform well in New England, they handle snow, freeze-thaw cycles, and wind-driven rain. Vinyl is the budget-friendly default; LP SmartSide offers a more authentic wood appearance with strong impact and weather resistance. We'll walk through the trade-offs during your estimate.

Do you handle insurance claims for storm damage?

Yes. We have experience working with insurance adjusters on storm-damage roof claims and can provide documentation, measurements, and damage assessment to support your claim. Start with the Technician Call path so we can review your specific situation.

How often should I replace my gutters?

Most aluminum gutters last 20+ years with proper maintenance. Signs it's time to replace include sagging sections, persistent leaks at seams, rust, separation from the fascia, or water pooling near your foundation. Seamless aluminum gutters reduce leak points compared to sectional gutters.
