Boulder Roof Leak Repair
Boulder roofs face intense sun, freeze-thaw cycles, high winds and hail, all of which stress shingles, flashing and sealants. Leaks usually start at penetrations and transitions rather than in open roof areas, and winter ice can push water under shingles at the eaves.
This guide covers common sources, permits and costs.
Common leak sources
Cracked pipe boots, failed flashing at chimneys, skylights and walls, wind-lifted or creased shingles, hail-damaged areas, and ice damming at eaves. Flat and low-slope roofs often leak at seams, drains and parapet flashing. Condensation from poor attic ventilation can look like a leak.
Temporary measures
Catch water, protect belongings and avoid going on icy or wet roofs. A professional tarp can protect an opening until repair; in winter, heat cables or snow removal at eaves may be recommended by a roofer to limit ice dams.
Permits for repairs
The City's roofing guidelines require a roofing permit for any repair, removal, overlay or recovery of more than one square, 100 square feet. Small repairs under that threshold do not need a roofing permit but should still meet code. Repairs on roofs with solar panels may require an electrical permit if panels are removed.
Costs
Published 2026 estimates put typical leak repairs at $360–$1,550 and general roof repairs at $395–$1,967. Steep roofs, tile or metal systems and high-wind nailing requirements increase cost.
Repair vs. replacement
Repeated leaks on an older or hail-damaged roof often point toward replacement. If the roof has two or more layers, a replacement must remove all of them under the City's guidelines.
Choosing a roofer
Ask the roofer how they traced the leak, what the repair includes, and whether a permit is required for the area involved. Get photos before and after. Colorado does not have a statewide roofing license, so check local registration and insurance, and references.
