River City Roofing | Roofing Services in Longmont, CO 80501

Our detailed roof inspection specifically looks for signs of wear common in our area. We check for excessive granules in gutters (indicating shingle aging from sun/hail) and assess the attic ventilation and insulation, which are critical factors in preventing ice dam formation. This proactive check helps us catch small issues before they lead to leaks or structural damage, saving you money and stress.

For Longmont homes, the decision often hinges on the extent of weather-related damage. If your roof has widespread granule loss, multiple leaks from ice dams, or has reached the end of its lifespan (typically 20-25 years for asphalt shingles here), a full replacement is usually best. A reroof (adding a second layer) can be a cost-effective option if there's only one existing layer and the decking is undamaged, but we'll always advise based on the long-term health of your roof.

Preventing ice dams starts with proper installation. We focus on creating a continuous thermal barrier with adequate attic insulation and installing a waterproof ice and water shield along the eaves—a critical step for Longmont winters. We also ensure proper ventilation to keep the roof deck cold and prevent snow melt. Using high-quality, impact-resistant shingles also helps combat the granule loss we see from hail, giving you a durable, worry-free roof.
