Hi Guys. i wanted to know if anyone is doing cedar roofs there seems to be a good market for it in my area. i mostly do fleet washing but thinking of checking out some residential. what is the most used method for this i ve heard some use a precarbnate cleaner followed by a wood brightener. Ive head just bleach and water. then treat with a stain. Ive also heard of some using Air. anyone know where i can find some info on this. thanks for your time

There aren't too many cedar shake roofs in Central Florida and I've never cleaned one, but I did some digging and found a little info on the topic.

http://www.cedarbureau.org/faq/maintenance.htm

I'm not sure if this organization is anything like what ARMA is to asphalt shingles, but it's a start for some info. I'll do some more digging and see what I can turn up.

Yes, they are a nightmare LOL. You have to walk them and wash every inch of them with low pressure. Often times they are brittle and crumblng and covered with some type of mold. Very fun when wet.

I bid over $20,000 (clean, ph balance, seal with two coats of WT) on one earlier this season and the customer took it. Now I am dreading the project. This is the house. Keep in mind I am sitting in my truck 300 feet away.

Ken, I went to school at University Of Washington in Seattle, and worked my way through schools doing roofing work.

Wood shake roofs like these are cleaned every day in the Pacific Northwest by spraying first with a Sodium Hydrooxide based cleaner.
Percarbonate MAY be better, but we never used it.

You spray the Sodium Hydroxide, wait 20 to 30 minutes, and rinse off with low pressure.

On a house like this, I might use a water broom type of contraption.

Though it isn't the right way, I knew plenty of Seattle area companies that simply sprayed them with strong Chlorine, then rinsed with a mild Acid/water solution to neutralize!

They would then wait for a good rain, and come back and stain them.
Quick and dirty, but it worked for them.

I do big roofs like this every now and then, but Tile or shingle, not shake, We do not see a lot of Shake here in Florida.

I just sold a 7800 sq ft Tile one, in an exclusive part of Tampa, just waiting for this tropical depression to leave ....

Our company specializes in the pressure washing of cedar roofs prior to the repair and treatment from a cedar roof restoration company.

We have mastered this art and can help anyone with any info they may have regarding the cleaning of a cedar roof.

We are based in Vancouver BC and we pressure wash cedar roofs all day, every day...even when it snows! This morning I sent one crew of two people to a house with approximately 5000 Sq.' of cedar roof and another guy to a house with about 2200 Sq.' of cedar roof and everything will be fully cleaned including the mess by the end of the day. 65% of the roofs around here are very steep and require the use of harnesses, ropes & roof seats. As I said already, this work is truely an art so if anyone has any questions, feel free to ask so we can fill you in.

Thank you.

Jason Wood

We will be putting together a package for everyone to learn the proper procedures to do this the correct way.

Thank you

I was wanting to know if you can share what chems you used and stain or sealer you using?

If someone has the quoted text from Wood Org's post in an email and copy and paste it would be cool?
