We install multi-family roofing across the Front Range, coordinated with siding where both are in scope. Our default specification is GAF’s Timberline ArmorShield impact-rated shingle: Class 4 under UL 2218, with wind coverage to 130 mph when installed to GAF’s system requirements.
Every roof is installed to manufacturer specification, which is what keeps the shingle warranty valid. We register the warranty on your behalf and hand over the documentation.
Colorado’s weather can be rough with hail, high winds, and freeze-thaw cycles that wear down a roof fast. That’s why it’s important to choose materials that can stand up to those conditions.
Class 4 is the highest impact rating under UL 2218. The test drops a 2-inch steel ball onto the shingle from a set height, twice on the same spot, and the shingle passes only if the mat does not crack. It is a laboratory standard rather than a guarantee against hail damage, but it is the best available predictor of how a shingle will hold up in a Front Range storm. Choosing this type of shingle is one of the best ways to protect your roof and keep it performing through Colorado’s toughest seasons.
Benefits for multi-family properties:
GAF Timberline ArmorShield II shingles are built for Colorado’s tough weather. Made with SBS-modified asphalt, they flex on impact and stay strong through hail, wind, and temperature swings. That flexibility keeps them from cracking and helps your roof last longer.
Key features include:
For a multi-family property, the case is straightforward: fewer hail claims across the portfolio, and one less thing on the reserve schedule for the next twenty years.
Every roof we install follows a detailed process to ensure precision, safety, and longevity.

Colorado hail is the main reason multi-family roofs get replaced here. A Class 4 specification is the most effective way to extend the interval between replacements and reduce claims across a portfolio.
