Colorado is hard on buildings. At high elevation, ultraviolet light is stronger than at sea level, so shingles, sealants and rubber parts dry out and age faster. Warm afternoons and cold nights make roofing materials expand and contract day after day, and frequent freeze-thaw cycles work water into every gap. Near the foothills, downslope chinook winds can lift and crease shingles, and the region sits in or next to Hail Alley, where large hail is common from roughly mid-April to mid-August.

That climate is why construction details matter so much here. The parts of a roof you can't see from the street, like the underlayment, ice-and-water membrane, drip edge and flashing covered in our guide to how a roof is layered, usually decide whether a roof lasts its full life or starts leaking early. The attic underneath matters just as much: without good air sealing and balanced attic ventilation, Colorado snow turns into ice dams at the eaves.
The guides below cover pitched-roof anatomy, attic ventilation and ice dams, commercial low-slope roof systems, and the order of exterior repairs after a storm. They're written for homeowners and building owners who want to understand the work before they hire someone to do it.
