Understanding Algae Growth

  2. Roofing Materials: Certain roofing materials are more susceptible to algae growth due to their composition.

Risks of Algae Infestation

  1. Aesthetic Impact: Algae growth can diminish your home’s curb appeal, reducing its overall value.
  2. Premature Aging: Algae can accelerate the aging of roofing materials, leading to a shorter lifespan.

Preventive Measures

  2. Zinc or Copper Strips: Install zinc or copper strips along roof ridges to release metals that inhibit algae growth.
