I’ve been walking away from every cedar shake job I’ve been offered but it has become too much to continue saying no. There are areas in my region where at least 50% of houses have cedar shake roofing and are in desperate need of a clean.
I’ve spent hours researching on here, reviewing Youtube (Everett Adams, Sullivan Roof Cleaning) and there seems to be no consensus on the proper way to clean them.
Some say SH, some say no SH, some say sodium percarbonate, some even say high pressure (?!?!) and others just say “their proprietary solution”. The only universal agreement seems to be to apply oxalic post-clean.
Have a large house looking to get this done ASAP so I am hoping someone may be able to point me in the direction of some factual advice. I’ve asked around in my immediate network and with people in my region from this forum but they do not do cedar shake.
House is all cedar shake roofing, has copper eaves (warned the homeowner about expectations already here if SH is used), some areas have a rug of moss, while others are just starting to go green. Attached pictures for reference.
I would sincerely appreciate any advice or even being pointed in the right direction to find an expert who may be able to assist here. Thank you in advance.
