Whether there’s a polar vortex, an unusually cold winter, or a lot of rain, Mother Nature takes her toll on your roof. A spring roof inspection can help you assess winter’s effect on your roof, chimney, vents and gutters.
What can Happen
1. Snow and ice can put extra pressure on roof shingles, possibly causing them to crack. Shingles can also bend under the weight, forcing them apart from other shingles, creating gaps where cold air and moisture can enter the house.
2. A warming period, followed by more sub-freezing weather, can cause snow and ice to melt, then refreeze. The resulting ice blocks rain and melted snow from flowing into the gutters, creating pools of water and adding to the weight on the roof. Roofers call this condition an ice dam.
3. In cold climates, attics have more insulation to keep heat inside. Since warm parts of the country don’t usually need the extra insulation, heat can more easily escape through the roof. This can cause snow to melt and reform as ice, increasing the risk for ice dams and shingle damage.
What to look for:
You can give your roof a pretty thorough look from the ladder. Remember to use extreme caution if you decide to climb onto the roof in early spring. Uneven shingles and patches of ice pose a serious risk of tripping and falling. Call a professional for roofing repairs in early spring or wait until you’re sure the roof is dry.
