W.H. Demmons, Inc. | Roofing Services in Portland, ME 04103

We understand these issues are common here. For ice dams, our approach includes proper attic ventilation and insulation during a roof replacement or installation to minimize heat loss from your home, which is a primary cause. We also ensure meticulous installation of ice and water shield along eaves and valleys. For granule loss, which can indicate aging shingles, we provide thorough inspections and recommend high-quality, durable shingles suited for our climate to ensure your roof has a long, protective lifespan.

The decision depends on the roof's age, extent of damage, and your long-term plans. Our experienced team provides honest assessments. For older roofs with widespread issues like frequent leaks or significant granule loss, a full replacement is often the most cost-effective and reliable solution. For newer roofs with isolated damage, a targeted repair may be sufficient. We'll explain all options clearly, helping you make an informed choice for your Portland home.

As a full-service mechanical contractor, we install air purification systems that use Bipolar Ionization technology. This process releases charged ions into your HVAC airflow that attach to and deactivate airborne particles, including viruses, mold spores, and allergens. It's a proactive way to enhance the health of your commercial or residential indoor environment. We can integrate this technology with your existing HVAC system or include it in a new installation, providing a comprehensive solution for cleaner air.
