Yes, it is a good idea to have a professional clean the debris off your roof. Cedar needs to breathe, and therefore any accumulation of needles, branches, leaves and dirt will affect its lifespan.

Zinc or copper strips nailed at the ridge cap can be used to control moss for a limited number of courses. Reaction between rain and the zinc or copper forms a mild solution that is carried down sections of the roof for two or three feet. The optional use of these strips can be eliminated if you are using Certi-Last® products. Complete care and maintenance recommendations are available in the CSSB’s Care & Maintenance Brochure.

For specific questions on paints, stains and coatings the CSSB recommends contacting your local, Member Contractor/Installer or local, competent, professional paint contractor or paint store.

The electro galvanized nails can get moisture through the shingle. Not only might they rust, but the paint on the nail head will come off and the rust will bleed through any cracks in the paint.
