• Project type: Roofing, siding, and gutter replacement on Spinnaker Place, Longmont, CO

• Primary material: GAF Armorshield II Charcoal impact-resistant shingles
• Outcome: improved weather resistance, structural integrity, and curb appeal across roof, siding, and gutters

Project Overview

On Spinnaker Place in Longmont, CO, WestPro tackled a full exterior renovation on a residential home, completing a steep-slope roof replacement, lap siding installation, and new gutter system. The roofing scope included a full tear-off of the existing shingles, installation of GAF Armorshield II shingles in Charcoal — a Class 4 hail-resistant upgrade — along with GAF FeltBuster underlayment, GAF Leak Barrier on all eaves, a GAF SnowCountry ridge vent, and new drip edge flashing around the perimeter. The siding scope involved removing the existing exterior cladding, re-decking a significant portion of the home with new OSB sheathing, and installing new lap siding with Arctic White trim, soffit, and fascia. New gutters and downspouts in white were added to complete the exterior package.

Results

The finished home on Spinnaker Place features a clean, cohesive exterior with GAF Armorshield II Charcoal shingles that carry Class 4 hail-resistance ratings — a meaningful advantage in Colorado's hail-prone climate. The re-decking of approximately 75% of the home's wall sheathing corrected underlying structural deficiencies and gave the new siding a solid, straight nailing surface. New white gutters and downspouts direct water away from the foundation, and the updated soffit and fascia complete a polished, well-sealed envelope. Tate expressed strong satisfaction with the finished project and noted he would be happy to recommend WestPro to others, and the GAF warranty was registered upon project close.

Materials Used

The roofing system was built around GAF Armorshield II shingles in Charcoal, a Class 4 impact-resistant product, paired with GAF FeltBuster synthetic underlayment, GAF Leak Barrier ice-and-water protection on all eaves, a GAF SnowCountry ridge vent, and 2x4-inch drip edge flashing. All pipe jacks and exhaust vents were replaced, and the two existing dome skylights were removed and plugged with OSB and plywood. The siding installation used lap siding with Arctic White trim — the only color confirmed in the extracted materials record — along with matching Arctic White soffit, fascia, and gutters. New OSB wall sheathing was installed across the majority of the home's exterior prior to siding installation to address deteriorated decking discovered during the project.
