We typically respond to emergency calls within a few hours during business hours, and we offer 24/7 emergency service for urgent situations like active leaks or storm damage. Emergency response means getting your roof secured to prevent further damage, then scheduling the permanent repairs. We keep tarps, emergency patching materials, and basic tools ready so we can stabilize most situations quickly. For non-emergency repairs, we usually schedule within a week depending on weather and our current workload.
Yes, we work with insurance companies regularly and can help document damage properly for your claim. We take detailed photos, provide written assessments, and can meet with adjusters to explain the scope of work needed. We know what insurance companies look for and how to present information that supports your claim. However, we always recommend you contact your insurance company first to start the claim process, then we can assist with the technical documentation and repair estimates they’ll need.
For Connecticut’s climate, we typically recommend architectural shingles rated for high winds and impact resistance. These handle our freeze-thaw cycles better than basic three-tab shingles and offer better protection against hail and wind damage. For flat or low-slope roofs, modified bitumen or EPDM rubber systems work well. The key is proper installation with adequate ventilation and ice dam prevention measures. We’ll recommend specific materials based on your roof’s pitch, exposure, and your budget, but we always prioritize materials that are proven to perform in New England weather.
Ice dam prevention starts with proper attic insulation and ventilation. We ensure adequate airflow from soffit vents to ridge vents, which keeps your roof deck temperature consistent. Proper insulation prevents heat from escaping through the roof and melting snow unevenly. We also install ice and water shield membrane in vulnerable areas like eaves, valleys, and around penetrations. For existing ice dam problems, we can add heat cables or improve ventilation, but the permanent solution is addressing the insulation and airflow issues that cause the problem.
Most residential roof replacements in Hanover take 2-4 days depending on the size of the house, complexity of the roof design, and weather conditions. Simple ranch homes might be completed in two days, while larger colonials or homes with multiple dormers and angles take longer. We work efficiently but don’t rush quality. Weather delays are common in Connecticut, especially during winter months, but we’ll keep you informed about any schedule changes. We always secure your home completely at the end of each day so you’re protected even if the project spans multiple days.
Our warranties cover both materials and workmanship. Material warranties come directly from manufacturers and typically range from 20-50 years depending on the product. Our workmanship warranty covers installation issues for a minimum of five years. This includes problems with flashing, ventilation installation, or any other installation-related issues. We’re a local company, so we’ll be here to honor our warranty commitments. We also provide clear documentation of what’s covered and maintain records of your project so there’s never confusion about warranty coverage down the road.
