Living in the mountains offers breathtaking views and a unique lifestyle, but it also brings specific challenges for homeowners—especially when it comes to roofs. The rugged mountain climate, heavy snowfall, high winds, and fluctuating temperatures can put significant stress on roofing materials. In this blog post, the experts from Nickerson Roofing take a look at some of the most common roofing problems in mountainous regions, along with tips on how to prevent them.
Heavy Snow & Ice Accumulation
In mountainous areas, snowfall can be both beautiful and problematic. When large amounts of snow pile up, the added weight can stress or even damage a roof. Ice dams—a common occurrence in colder regions—form when snow melts, runs down the roof, and refreezes at the edge, creating a barrier. This can cause water to back up under the shingles, leading to leaks and water damage inside the home.
Prevention Tip: Invest in a roof designed to withstand heavy snow loads and consider installing heating cables along the edges to prevent ice dam formation. Regularly clear snow from the roof with a roof rake or call a professional if there’s heavy accumulation.
High Winds & Roofing Shingle Damage
Mountain areas often experience high winds that can lift or tear away roofing materials, leaving the underlayers exposed to water and debris. Strong winds can also loosen shingles over time, increasing the chance of leaks.
Prevention Tip: Use high-quality, wind-resistant roofing materials and inspect the roof after storms. Reinforcing areas prone to wind damage, such as eaves and ridges, can also help increase the roof’s durability.
Temperature Fluctuations & Material Expansion
Mountain climates are known for dramatic temperature swings, which can cause roofing materials to expand and contract. This constant movement weakens materials, creating gaps, cracks, and leaks.
Prevention Tip: Choose roofing materials that are designed to withstand temperature changes, such as metal or specially treated shingles. An experienced roofer can also install expansion joints that accommodate movement without damaging the roof.
UV Damage from High Altitude Exposure
The higher altitude in mountain regions means increased exposure to UV rays, which can accelerate the breakdown of roofing materials. Shingles can become brittle, and other materials may start to warp or crack.
Prevention Tip: Look for UV-resistant roofing materials, like certain types of metal or UV-treated asphalt shingles. Applying protective coatings to the roof can also extend its life.
Falling Debris from Trees & Rockslides
Mountainous areas often have dense forests, and falling branches or even entire trees can pose a serious threat to your roof. In certain areas, rockslides or loose debris can also damage the structure.
Prevention Tip: Regularly trim overhanging branches and remove any dead or diseased trees near the house. Consider reinforcing the roof with impact-resistant materials if your home is in an area prone to falling debris.
Excess Moisture & Moss Growth on Roof
Mountain environments often have higher moisture levels, creating the perfect conditions for moss, algae, and lichen growth on your roof. These can hold moisture against the roof surface, leading to rot and decay.
Prevention Tip: Treat the roof with an anti-moss solution and ensure it has proper drainage. Consider installing zinc or copper strips along the ridge, as rainwater runoff from these metals naturally prevents moss and algae growth.
