Project guide
Roof moss, gutter and exterior cleaning in Oregon
Clearing gutters, cleaning a roof and applying moss-control products are different tasks. Ask which services the company actually provides rather than assuming every exterior cleaner does them all.

What to include in your estimate request
Define surfaces and methods
- Specify gutters, downspouts, roof sections, siding or paving. Ask how the proposed method fits each material and its condition.
- Separate debris removal, rinsing, chemical treatment and repairs. Ask how plants, openings and runoff will be protected.
Check treatment and exclusions
- Ask whether moss-control products will be applied and request the applicable pesticide credential check for that activity.
- A cleaning visit need not include roof repair or gutter replacement. Ask for photographs and a separate repair scope when issues are found.
Oregon credential and permit starting points
ODA’s roof-use bulletin distinguishes pesticide application from ordinary cleaning. Check applicable ODA credentials for chemical moss treatment; a CCB record alone does not establish those credentials.

Common questions
Does gutter cleaning include roof moss treatment?
Do not assume it does. Ask for separate services, methods and prices.
Are the related roof businesses checked for chemical treatment?
The listed profiles describe their published roofing services. Chemical-treatment credentials still need a scope-specific ODA check.
