Canada experiences very volatile weather conditions that place significant stress on the widespread residential buildings nationwide. From Atlantic hurricanes to hefty prairie hailstorms, Canadian homeowners should understand how environmental stressors affect a building’s structural integrity over the long term. 

There are times when fallen trees in Fredericton cause massive destruction, but the gradual erosion of roofing materials typically remains hidden for a long time. Knowing about shingles and their lifestyle enables homeowners to make informed decisions about maintenance and avoid unnecessary professional interventions. 

Recognizing the sourcing right after a storm 

Protective granules serve as a major barrier for your home against the harsh UV rays from Canada. The tiny stone particles reflect sunlight away from the asphalt under the granules, thereby preventing it from becoming brittle and melting during the summer heat. If a storm causes physical damage from wind or hail, there will be no granules left on the roof, which will age the asphalt underneath rapidly due to sun exposure and eventually lead to cracks and water damage. Homeowners can count on storm damage roof repair Fredericton for help with this and to balance the damage. 

Evaluating life expectancy in the long run 

A roof can lose a significant number of granules after a storm hits, and might find it challenging to reflect its full twenty-year manufacturer rating. All experts agree that heavy scouring can reduce the functional life of the roof by thirty to forty percent. Hence, it exposes the remaining asphalt to thermal shock, where the shingles will expand and contract too rapidly. This adds more stress to the shingles, creating a curling edge and a lack of adhesive, making it susceptible to other wind events.

Signs that tell you it’s time for professional help

  • Fibreglass mats that peek through shingle surfaces right after a wind. 
  • Mineral granule piles are gathering at the downspouts at your home base. 
  • Bald spots on the shingles appear metallic and shiny when viewed from ground level. 
  • Missing and losing shingles that are exposed to the external elements on the surface of the wood decking. 
  • Constant water spotting inside the ceiling after moderate rainfalls. 

Necessary steps for inspection and maintenance

  • Clear the gutters daily to monitor the volume of mineral debris washed away. 
  • You can trim overhanging tree branches to reduce the risk of mechanical damage during high-wind gusts. 
  • Take a look at the attic for signs of moisture or daylight peeking through the upper roof boards.
