A roof in Denver works harder than almost anywhere else in the country. At 5,280 feet, ultraviolet exposure is roughly 25% stronger than at sea level, baking asphalt shingles year-round. Add 60+ freeze-thaw cycles each winter, chinook winds that gust past 80 mph, and hail nearly every summer — and most Denver roofs reach the end of their service life at 18–22 years rather than the 30 on the wrapper. Our replacements are built for exactly this environment: full tear-off to the deck, synthetic underlayment, ice-and-water shield at all eaves and valleys, high-profile ridge ventilation, and shingles rated for high altitude and impact.
