The tool lets you explore Owens Corning asphalt shingle colors and styles, underlayment systems, and ice and water shield configurations. It is designed to help Colorado homeowners make confident decisions about both the look and the protective layers of their new roof before committing to a product.

Yes, the tool is completely free to use. No account, download, or payment is required. Simply visit the page, load your roof model, and start exploring color and material options.

Underlayment is a water-resistant or waterproof layer installed directly onto your roof deck, beneath the shingles. It acts as a secondary barrier against wind-driven rain and moisture. For Colorado homes, choosing the right underlayment, especially synthetic underlayment, is critical for protection against extreme weather and heavy snow loads.

Ice and water shield is a self-adhering waterproof membrane applied to the most vulnerable areas of your roof, typically along eaves, valleys, and penetrations. In Colorado, where freeze-thaw cycles and ice damming are common, ice and water shield is strongly recommended and required by building code in many mountain communities including Summit County.

Absolutely. The 3D roof designer is a great first step before your consultation with Excel Roofing. Exploring color options and system components ahead of time helps you arrive at your estimate appointment with a clearer sense of what you want, making the process faster and easier.
