We do not install "contractor grade" roofs. We engineer 50-year structural weather-defense systems designed to make hurricanes rethink their life choices.
Many homeowners delay roof replacements until water marks appear on the ceiling. Unfortunately, by the time interior leaking is visible, severe structural wood rot and costly drywall damage have already occurred in the attic. An engineered asphalt shingle roof generally has a reliable lifespan of 20 to 30 years. However, in extreme microclimates like those found across New Hampshire, Maine, and Vermont—where high UV exposure in the summer immediately violently contrasts with severe winter freeze/thaw cycles—this timeline can aggressively shrink if standard, low-grade builder materials were used originally.
You should consider utilizing our Instant Pricing Estimator if you notice any of the following critical failure signs:
Listen, we know hiring for a roof replacement is stressful. But do you know what's more stressful? Hiring the cheapest bid, enjoying a mildly satisfactory summer, and then watching water pour through your kitchen ceiling during the first major December ice storm.
If you don't hire us to do it right the first time, you'll probably end up paying us to fix the other guy's work next year anyway. At Nova Roofing & Siding, we do not compromise on the underlying architecture. The visible shingles only represent about 30% of what keeps your home dry.
A true, warrantied roof replacement involves multiple complex layers working in structural harmony. If one layer is omitted to save costs, the entire system fails. This is exactly why weather-specific engineering matters in New England.
Every Nova installation mandates a complete "tear-off" to the bare wood. We inspect every square inch of the plywood or plank decking because nailing a premium 50-year shingle to rotted wood is a guaranteed failure. Proper drip edge flashing is then installed to govern water tension at the rakes and eaves.
In states like Vermont and Maine, winter snow loads sit on roofs for months. The heat from your home causes bottom-layer melt, which drips down to the freezing eaves and solidifies into massive ice dams. If water backs up *under* your shingles, only a dense, rubberized Asphalt Ice & Water shield can prevent catastrophic interior leaking. We aggressively apply this shield far beyond standard local code minimums.
Traditional felt paper rips and traps moisture. We employ breathable, ultra-high-strength synthetic underlayments. On top, we secure premium architectural shingles utilizing specialized high-wind nailing patterns (often 6 nails per shingle instead of the standard 4) to protect against severe coastal Nor'easter wind-shear commonly seen from Portsmouth, NH up to Portland, ME.
Due to our specialized project management crews, 90% of our residential roof replacements are fully torn-off, inspected, installed, and entirely cleaned up in 1 to 2 days.
No. Our Field Project Managers oversee the entire crew. As long as we have access to power and your driveway is clear of vehicles, you can go about your normal day.
If your roof is over 15-20 years old, experiencing wide-spread granular loss, or multiple structural leaks, a full replacement is safer and far more cost-effective than attempting continuous, expensive patch repairs that fail to address the core problem.
