Common Roofing Terms Every Homeowner Should Know

Roof failure can sneak up on homeowners, especially in areas like Washington and Idaho where unique climate conditions create a perfect storm for roofing wear and tear. From heavy rains in western Washington to snowy winters in Idaho, homes in the Northwest are exposed to a wide range of environmental stressors that can shorten a roof’s lifespan. Understanding the early warning signs of roof failure—and knowing when it’s time to call a professional—can save thousands in repairs. Here are 7 signs of early roof failure, and how the Northwest's climate contributes to roof deterioration: 1. Moss and Algae Growth Western Washington’s wet climate creates ideal conditions for moss and algae . These organisms trap moisture on your roof, which can lead to shingle degradation and rot. Left untreated, moss can lift shingles and cause leaks. 2. Curling or Warped Shingles Extreme weather changes in both Washington and Idaho—rain, snow, sun—can cause shingles to expand and contract. Over time, this leads to curling, cracking, or warping, leaving your roof vulnerable to water infiltration. 3. Granule Loss Asphalt shingles lose granules with age , but in climates with heavy rain or snow, this process can accelerate. You may notice bald spots on shingles or granules collecting in gutters, both signs that your roof is nearing the end of its life. 4. Ice Dams In Idaho, where heavy snowfall is common, poor attic insulation and ventilation can lead to ice dams —ridges of ice that prevent melting snow from draining. Water backs up under shingles and leaks into your home, causing structural damage. 5. Water Stains or Mold Inside the Home Stains on ceilings or mold along walls are common signs of a leaky roof. In the damp Northwest, even small leaks can lead to rapid mold growth, putting your health and home at risk. 6. Sagging Rooflines A sagging roofline may indicate trapped moisture in the roof decking or structural issues due to prolonged exposure to snow loads in Idaho or standing water in rainy parts of Washington. 7. Missing or Loose Shingles High winds and frequent storms in both states can loosen or blow off shingles. Missing shingles expose your roof’s underlayment to moisture and UV damage, speeding up deterioration.

The Pacific Northwest is no stranger to wet, chilly winters. Between pounding rainstorms, the occasional snow dump, and freezing overnight temps, your roof takes a beating from November through March. And if your roof is already showing its age? That winter wear and tear could mean leaks, damage, and costly repairs ahead. That’s why spring is the perfect time for a post-winter roof inspection—especially if you’ve got an older asphalt shingle roof. Catching issues early can save you thousands, and maybe even extend the life of your roof by a few more seasons. What Winter Weather Does to Aging Roofs Even if you didn’t have a major weather event this winter, the day-to-day exposure can be just as damaging over time. Here's what to look out for: Snow : Freeze-Thaw Damage While heavy snow isn't as common at lower elevations, even light snow that sticks around can cause: Ice dams that force water back under shingles Freezing and expansion that cracks old, brittle shingles Moisture retention that softens decking and underlayment Rain : Constant Saturation The PNW gets more than its fair share of rain. For older shingles that have lost their granules and protective coatings, that means: Water infiltration through microscopic cracks or gaps Accelerated wear from the constant moisture Moss and algae growth, especially in shaded or tree-covered areas Cold : Shrinkage and Cracking Frigid temps cause shingles to contract, especially at night. With aging shingles, that can lead to: Cracks and curling edges Exposed nail heads that invite leaks Loss of adhesion, letting wind and water get underneath Signs It’s Time for a Post-Winter Roof Check You don’t have to climb a ladder to know your roof might need attention. Look for: Shingles that look curled, cracked, or missing Dark streaks or green patches (hello, moss) Water stains on your attic ceiling or interior walls Debris in your gutters that looks like shingle granules If you spot any of these, it’s time to call in a professional—or better yet, a roofing contractor who uses Owens Corning roofing products. Why Choose Owens Corning for Replacement? If your roof is ready to replace, Owens Corning offers some of the best solutions on the market for wet, cold climates like the PNW.
