Roof Mold

Over the years, mold, moss, fungi or algae sometimes develop on roofs due to accumulated dust, dirt and other organic waste. If this is the case, we recommend to wash the roof with a diluted bleach cleaning solution to keep your asphalt shingles from degrading faster. This cleaning will remove algae stains and extend your roof’s lifespan. Please note that pressure washing is strongly discouraged because it also washes away granules.

Missing Shingles

If roof shingles have blown off in a storm or strong wind, you must replace the missing shingles to avoid water infiltration and any further damage. If the other shingles are in generally good condition, you might need only to replace the missing shingles, rather than the entire roof. Harsh winters can cause shingle damage due to ice and snow. If the remaining shingles are in poor general condition or if too many shingles are missing, then you should install new asphalt shingles. When you regularly monitor the condition of your roof, you can either repair or replace shingles to avoid damage and leaks or replace all your shingles if required by their general condition and age.

Tips for Keeping Your Roof in Good Condition

Tips for Keeping Your Roof in Good Condition:

  • Choose shingles with the best installation and material warranty.

  • Hire a certified roofer or follow the manufacturer’s instructions if you are installing the shingles yourself. This guarantees their durability and warranty protection in the event of defect.

  • Conduct an annual visual inspection to quickly identify visible warning signs such as mold, algae, waves, cracks or missing shingles.

  • Make sure that the attic is well ventilated, in accordance with the manufacturer’s instructions and the building code, to avoid warping or premature aging.

  • Avoid replacing your roof in the winter because cold temperatures could alter the shingles’ adherence to the roof.
