Johnson Home Improvement | General Contractors & Roofing in Roanoke, VA 24015

We install roofing systems with algae-resistant shingles specifically designed for our humid Virginia climate. These shingles contain copper granules that inhibit the growth of the black algae streaks you often see on local roofs. This not only improves your home's curb appeal but also protects the shingle integrity, extending the life of your roof against a very common local issue.

In Roanoke's climate, temperature fluctuations can cause condensation in poorly insulated attics, leading to moisture damage, mold, and reduced energy efficiency. As part of our roofing service, we assess and upgrade attic ventilation and insulation. This creates a balanced system that allows moisture to escape, keeping your attic dry, your energy bills lower, and preventing the wood rot and ice dam problems we see too often locally.

Absolutely. Drafty, old windows contribute to temperature imbalances in your home, forcing your HVAC system to work harder. This excess activity can increase humidity levels in the attic, exacerbating moisture issues near your roof structure. Our energy-efficient window installations create a tighter building envelope. This helps maintain consistent indoor temperatures, reduces strain on your roof's ventilation system, and works in tandem with a healthy roof to protect your entire home from moisture damage.
