Services
Residential Roofing
We specialize in residential roofing solutions including asphalt shingles, metal roofing, and tile installations. Our team handles new construction, re-roofs, and hail damage repairs while maintaining strict quality control throughout the installation process. With over 30 years of local experience, we ensure proper ventilation and waterproofing to protect homes against Colorado's extreme weather conditions.
Commercial Roofing
Our commercial roofing services cater to retail establishments, restaurants, and multi-family housing complexes. We install durable flat roofing systems, standing seam metal roofs, and custom architectural sheet metal components. Certified installers work with major manufacturers to provide long-lasting solutions for warehouses, municipal buildings, and franchise operations across the Rocky Mountain region.
Gutter Installation
We design and install 5 and 6 seamless gutter systems using premium materials that resist Colorado's weather extremes. Our specialists handle standard K-style gutters and architectural half-round systems with matching downspouts. Proper installation prevents water damage to foundations while maintaining property aesthetics through color-matched and custom-finished options.
Roof Repair
Emergency and scheduled roof repair services address leaks, storm damage, and wear from Colorado's variable climate. Our technicians perform comprehensive inspections to identify hidden issues beneath shingles and in attic spaces. We offer preventive maintenance programs with annual inspections to extend roof lifespan and maintain manufacturer warranties.
Emergency Services
Available for urgent roof leaks and storm damage across our service area. Our emergency team responds promptly to protect properties from further water intrusion using temporary sealing and tarping solutions. We coordinate with insurance claims adjusters and provide documentation for covered damages while scheduling permanent repairs at the earliest opportunity.
Questions
Do I need a full roof replacement for a leak?
Not necessarily. Leaks often stem from damaged flashings or localized wear. Our technicians assess roof age and condition to determine if repairs suffice or replacement is needed.
Are your estimates free?
Yes, we provide free estimates for full roof replacements and new construction projects. Repair estimates carry a $265 fee that applies toward completed repairs.
What warranties do you offer?
We provide workmanship warranties on installations. Manufacturers offer separate material warranties. Both cover defects in installation or production, excluding weather-related damage.
Can I install a new roof over existing materials?
While some jurisdictions allow overlays, we recommend removing old materials to ensure proper inspection and installation. Many areas now require complete removal to decking for code compliance.
How should I prepare for a reroof?
Clear driveway access for material delivery, secure indoor valuables, and ensure pets are contained. You don't need to be home during work but should remain reachable for urgent matters.
Do you handle gutter cleaning?
We install and repair gutters but don't provide cleaning services. We recommend bi-annual maintenance to prevent clogs and water damage to foundations.
