Got questions? We’ve got straight answers.
In New England’s climate, architectural asphalt shingles typically last 18 to 30 years. Factors like attic ventilation, shingle brand, and installation quality play a major role in longevity. Ice dams, snow load, and heavy winds also take a toll over time, which is why proper installation matters.
Architectural shingles are the top choice for most homes—they offer better durability, wind resistance, and appearance compared to basic 3-tab shingles. We recommend GAF Timberline architectural shingles for their strong warranties and proven performance.
Signs include curling, cracking, missing shingles, granule loss, moss or algae growth, or interior water stains. A professional inspection can determine if a full replacement is needed or if repairs will suffice.
Technically yes, but we don’t recommend it and most building inspectors won’t allow it. We always perform a complete tear-off to inspect the roof deck, ensure proper underlayment, and give you the best long-term performance—and full manufacturer warranty protection.
Yes. High-quality architectural shingles are designed to withstand heavy wind, rain, snow, and temperature fluctuations—especially when installed by a certified team like ours.
Absolutely. Asphalt shingles are available in a wide range of colors and textures to match your home’s style. We’ll walk you through options and even show past installations so you can see them “in action.”
Yes. We offer manufacturer warranties (often 25 years to lifetime, depending on the product) along with our own workmanship guarantee for added peace of mind.
Yes. A new roof improves curb appeal, buyer confidence, and resale value, especially when installed by a respected contractor with a reputation for quality.
Most residential roofs are completed in 1 to 2 days, weather permitting. We plan carefully to minimize disruption and keep your property clean and protected throughout the process.
Keep your gutters clean, trim back overhanging branches, and schedule occasional roof inspections to catch small issues before they become major problems. Avoid pressure washing or harsh chemical treatments.
In most cases, a roof replacement is considered a home improvement, not a repair—so it's not tax deductible unless it's for a rental or business property. However, energy-efficient roofing products may qualify for tax credits, so check with your tax advisor.
If overhead power lines run close to your roof, it’s important to contact your local utility company before the roofing project begins. In most cases, they will install protective sleeves or temporarily disconnect service to ensure a safe work environment for the crew.
J. Carnes & Son Roofing requires this to be done prior to installation if power lines pose a safety concern. We’re happy to point it out during your estimate and provide guidance, but the homeowner is responsible for coordinating with the power company directly.
