Roofing 911: Moss & Mold

In many regions, moss and mold growth on roofing surfaces is as common as the morning dew. But just because it’s a frequent sight doesn’t mean it’s harmless. Both moss and mold thrive in damp, shaded conditions, which many roofs inadvertently provide. While moss gives a rustic, fairy tale aesthetic, it poses a significant threat to roof integrity. Moss absorbs and retains moisture, leading to a perpetually damp environment. Over time, this can compromise the roofing material, leading to decay, rot, and leaks. Moreover, mold, a more insidious invader, can lead to both structural damage and health issues for the home’s inhabitants if it finds its way inside.


Signs of Moss & Mold

Homeowners should be proactive in inspecting their roofs for early signs of moss and mold damage. Moss is relatively easy to spot – its green, bushy texture is unmistakable. However, mold might be more elusive. Some indicative signs include:

  • Dark streaks or patches on the roofing material.
  • A musty smell in the attic or upper rooms.
  • Frequent allergies or respiratory issues among household members.
  • Noticeable dampness or water stains on the underside of the roof or in the attic.
  • Remember, early detection can save thousands in repair costs and prevent potential health hazards.

Roofs at Risk

Certain roofing materials inherently harbor a higher risk for moss and mold colonization than others. Wooden shingles, due to their organic nature, are particularly susceptible. Their rough texture and natural composition create a conducive environment for moss and mold to take root. Asphalt shingles, with their granulated structure, can also trap moisture and organic debris, becoming a haven for these unwanted growths. Flat roofs, regardless of material, are more prone as well since they lack the slope that aids in the natural runoff of water. In regions with high humidity, frequent rainfall, or heavy tree cover that shades roofs and traps moisture, these roofing types require extra vigilance to prevent moss and mold proliferation.


Preventative Measures

The best way to deal with moss and mold is to prevent them from gaining a foothold in the first place. Some preventive measures include:

  • Keeping gutters clean and ensuring proper water drainage away from the roof.
  • Trimming tree branches that overshadow the roof, ensuring it gets adequate sunlight.
  • Installing zinc or copper strips at the roof’s peak; when rainwater flows over these metals, it washes away moss-spurring particles.
  • Regularly inspecting your roof, especially after heavy rains or long periods of damp weather.
