Roof & moss care

Start with the roof.
Not a one-size-fits-all method.

Ask the provider to assess the roof material and condition, explain the proposed work, and follow applicable manufacturer guidance.

Separate these three tasks

1. Debris clearing

Ask what loose debris will be removed, how it will be removed, and whether gutters and downspouts are included afterward.

2. Moss removal

Ask whether existing growth will be removed and how the provider will avoid damaging roofing. Do not assume a service called “roof cleaning” uses one particular method.

3. Moss treatment

Ask which product is proposed, what the label requires, how runoff and plants will be protected, and what result and timeline you should expect in writing.

Put these questions in the quote

  • Is the proposed method compatible with this roof material and its warranty requirements?
  • What condition or damage would make the crew stop and recommend a roofer?
  • How are roof access, fall protection, nearby plants and cleanup handled?
  • Is a return visit included, and what does any treatment guarantee actually cover?
