Frequently Asked Questions
What is GoNano roof treatment, and how does it protect my home in Colorado?
Our NRCIA-certified GoNano treatment is a specialized sealer that provides deep, long-lasting protection against Colorado's harsh weather, including intense sun, hail, and freeze-thaw cycles. It penetrates roofing materials to create a durable barrier, which is why we confidently back it with a 10-year warranty. This service is ideal during a roof replacement, new installation, or re-roofing to extend your roof's lifespan significantly.
We're planning to build a detached garage in Peyton. Can you handle the entire project?
Absolutely. As a full-service general contractor with over 35 years of experience, we manage every phase of new structure construction, from detached garages to single-family homes. Owner Mark Walp oversees each project directly, ensuring clear communication and craftsmanship that meets our high standards. We also partner with Lester Building Systems for durable, pre-engineered options, providing a seamless build from foundation to finish.
I've noticed nail pops and a leak near my skylight. How do you address these common local issues?
Nail pops and skylight leaks are frequent concerns in our area due to temperature swings and settling. During a roof inspection, we identify the root cause—often improper sealing or fastener failure. For repairs, we address the specific leak point with precision flashing and sealants. For widespread nail pops, a roof replacement or re-roofing with our GoNano treatment provides a comprehensive, long-term solution, preventing future moisture intrusion and protecting your home's integrity.
