Dempsey Roofing | Roofing Services in Billerica, MA 01821

Our roof replacement process is thorough and designed for lasting protection. We start with a detailed inspection of your existing roof structure, paying close attention to common local issues like ventilation and underlayment condition. Our experienced crew then safely removes the old materials, which we responsibly recycle. We install high-quality asphalt shingles or rubber roofing with precision, ensuring proper sealing and ventilation to withstand New England's weather. Throughout the project, our team follows all OSHA safety protocols to protect your property and our workers.

Yes, we frequently install skylights on existing roofs. Our team, with over four decades of combined experience from Eric and Radek, first assesses your roof's structure to ensure it can support the new skylight without compromising integrity. We carefully integrate the skylight with your roofing system, using expert flashing techniques to prevent leaks—a critical step given our local climate. Proper installation also considers attic ventilation to prevent ice dams and moisture issues common in the area.

Poor ventilation and underlayment damage are frequent causes of ice dams and interior moisture in our region. During any inspection or reroofing project, we specifically evaluate your attic's airflow and the condition of the roof deck and underlayment. We correct ventilation issues by installing or upgrading soffit and ridge vents to regulate temperature and moisture. If the underlayment is compromised, we replace it with a high-grade, water-resistant barrier. This targeted approach protects your home from the seasonal freeze-thaw cycles that can lead to costly damage.
