Why Does My Roof Have Mold?

Why Does My Roof Have Mold?

If you live in one of the country’s many humid regions, odds are you’ve seen some discoloration or unsightly black streaks on your roof. Maybe you see some fuzzy brown or green fungal growth or even a slick film on the edge of your roof tiles. If so, mold has invaded your roof and, unless fixed quickly, could cost you dearly later.

Beyond the health risks presented by black mold, the fungus weakens the structural integrity of the entire home, placing anyone living inside at risk. Read on to learn more about what mold can do to your roof and what you can do to fight it.

Know Your Enemy

Mold spores travel in the air, but require the right environment to take hold and grow. A roof with little direct sunlight, that collects debris, or has improper drainage increases risk of mold. An undiscovered roof leak, water draining into the foundation, or debris gathering in a roof corner all create a nice, moist place for mold spores to grow.

If the mold remains on the surface, it will lead to ugly stains or black streaks. While not damaging to the roof in this state, it certainly reduces curb appeal and makes the house look older.

Inspect Everything

You will only know mold has gotten a foothold if you perform regular inspections. This is especially important if your roof doesn’t get a lot of direct sunlight, as mold grows in shaded areas. It pays to have a professional perform a roof inspection at least once a year.

Protect Your Home

Ensure proper ventilation throughout your home, including ridge vents. If you live in a humid environment or one with a lot of rainfall, or have a roof made of asphalt shingles, roll roofing, wood shingles, or wood shakes, consider upgrading your roofing material to more moisture-resistant types such as built-up roofing, or new algae-resistant asphalt shingles.

Clean Your Roof

Proper care and maintenance is critical in prolonging the life of your roof and your home. Having your roof inspected, taking steps to keep it clear of debris, and cleaning it regularly all help protect your investment.
