R C Exterior Improvements | Roofing Services in Nashua, NH 03062

Our soft washing method is specifically designed to be warranty-safe. We apply sodium hypochlorite at low pressure, which effectively eliminates mold and algae without the forceful blasting that can tear asphalt granules from shingles. Many manufacturers void warranties for high-pressure damage. Our gentle process cleans your roof thoroughly while keeping your shingles—and their warranty protection—fully intact.

Ice dams are a primary concern in our climate. When snow melts and refreezes at your roof's edge, it can back water up under the shingles, damaging the roof deck and interior. We also frequently see issues with underlayment, the water-resistant barrier beneath shingles, which can degrade over time or be compromised by ice dam leaks. During any service, we keep an eye out for these vulnerabilities common in Nashua.

High-pressure power washing can force water under shingles, damage the granular surface that protects asphalt, and shorten your roof's lifespan. Our soft washing uses a biodegradable cleaning solution applied with low pressure. This method kills the organic growth at the root, provides longer-lasting results, and eliminates the risk of physical damage to your roofing materials, making it the safer, more effective choice.
