Homeowners: Insurance Companies Are Demanding Roof Cleaning — Here’s What You Need to Know

At KC Power Clean, we’ve seen an incredible surge in roof cleaning requests — and for good reason.

Over the past several months, insurance companies have been warning homeowners: “Remove the moss on your roof, or risk losing your coverage.” This new wave of insurance inspections has made roof maintenance not just important, but urgent. As one of Orange County’s leading exterior cleaning companies, we’re here to help you stay protected — and informed.

We’ve been in the cleaning business for nearly 20 years, originally specializing in windows, floors, and carpets. But lately, roof cleaning has become one of our biggest priorities. With over 20 trained technicians on our team, we’re out in the field every day — and we’re often booked solid because so many homeowners are facing tight deadlines from their insurance providers.

Why the sudden attention to roofs?

Many homeowners — especially those who’ve lived in the same house for years without issues — are surprised when they get a notice. Traditionally, if the roof wasn’t leaking, people didn’t think much about it. But times have changed. Now, even a small amount of moss or lichen growth can trigger warnings or even threats of non-renewal from insurance companies.

Real Example:
One of our clients in Arcadia, Mrs. Li, shared that after more than a decade without any roof-related issues, she received a notice this March: “Clean the moss or lose your insurance coverage in 90 days.”
She’s not alone — about 80% of our roof cleaning projects today are tied to similar insurance demands.

Where’s all this moss coming from?

Even in sunny Southern California, certain homes — especially those near mountains, water, or shaded by large trees — can trap moisture. When debris like leaves and pine needles are left on roofs, it creates the perfect environment for moss and lichen to thrive.
From what we see every day:

  • A damp roof can grow moss within 3 years.
  • A dry roof, if neglected, can start greening in about 10 years.

Once moss sets in, it multiplies fast. It’s not just about looks either — moss and debris can trap moisture, damage roofing materials, and even cause the roof to warp or deform over time.

Why Are Insurance Companies Cracking Down?

While many people believe wildfires are the main reason insurance companies are raising rates or tightening rules, the bigger driver has actually been water damage — particularly from roof leaks.
Roofs are a critical part of protecting your home, and if they aren’t properly maintained, they can lead to costly claims for insurers.
Using drone technology, insurance inspectors can now easily spot:

  • Moss or lichen growth
  • Dark or discolored areas
  • Broken or missing tiles
  • Roofs with heavy debris buildup

Homes flagged as “high-risk” could face non-renewal notices or increased premiums — unless issues are addressed quickly.
