We see very few Cedar Shake Roofs here in Tampa. However, I have probably cleaned at least 35 of them in my 20 plus years in this business. I have always used a shingle roof strength mix of SH, water, and soap. I always told the customers that the cleaning would lighten the color of the roof a bit, and often did a sample on a small part of the cedar roofs to show them. I never once had any customers tell me no. Share this post Link to post Share on other sites
Jeff Mathieson Tartan Window Cleaning Report post Posted October 27, 2016 (edited) Mark I have had the same lack of response. Although $3000.00 US was a little rich for my cause. I found this the other day from http://shop.pressurewasherproducts.com/ dig around the site they have a good list of knowledge which is totally free. Hope this helps. Maybe this could be added to the content of the siteCedar Shingles, Wood Siding, etc. (2 STEPS) DO NOT USE Sodium Hypochlorite or Bleach. Sodium Hypochlorite or Bleach will permanently damage the wood breaking down the cellulose or structure of the wood and remove the natural colors and tones. 1.

Roof Cleaning Virginia Report post Posted October 27, 2016 (edited) I wonder how well this step works... ???THAT is THE proper process for cedar roofs and for wooden decks and privacy fences etc. It's called "3 stepping" and has been an industry standard for as long as I've been and business, and much longer I suppose.We've done cedar roofs both ways - 3 stepping, and for clients on a tight budget, with SH. 3 Stepping produces far superior looking results. SH causes a 'washed out" look after a brief period of time.Keep in mind that 3 stepping is very labor intensive! The last one we did took us 3 full days (including staining). It had a $6000 price tag, not including the cost of the stain.Excellent research effort Jeff.

Staining a cedar roof must has been very labor intensive... and uncomfortable... Did you apply the stain with a pump sprayer and then wipe down... OR... hand apply and wipe...???Staining all of the cabinetry that we have built in the years... LOTS of it ... Staining is a BIG JOB when you are staining large areas... !!!It's good to know that this procedure works as it should for cedar roofs... Definitely going into the memory bank... !!!

Jeff Mathieson Tartan Window Cleaning Report post Posted October 27, 2016 Thanks for endorsing this process Virginia Roof Cleaning. Sometimes I question some of the chemistry some folks put together. I am a little apprehensive to take on a cedar roof in my area as many are cedar shakes not shingles.I have been is attics of shake homes and the amount of daylight visible, shakes are nailed to horizontal strapping - I am in wonder how they ever stop the water.Walking on the shakes isn't a good thing due to the brittleness, and I would never want to rinse any direction but in the flow of the roof.Shingle, I would attempt. Shake, unless I had a experienced roofer for support, I feel a little vulnerable liability wise. 1 Hydro-Pro Power Wash reacted to this Share this post Link to post Share on other sites
Roof Cleaning Virginia Report post Posted October 27, 2016 4 gallon Top Draw backback sprayers for the stain. BTW - we used a stain product specifically made for cedar shakes. Far too labor intensive for me. We're fortunate to have TONS of asphalt roofs so we typically pass on the cedar jobs.Jeff - many shake roofs needs lots of repairs long before the client calls on us; Metal shims under the split shakes, ridge cap shakes in disrepair, end rot on shakes etc. The last one we were asked to quote was so punky, there's no way we'd even touch it. 2 Hydro-Pro Power Wash and JetBlueRacer reacted to this Share this post Link to post Share on other sites
