   thomas.. none that i know of.. most of it is just as you say...every two years..

   the secret to longevity of wood roofs is before and during installation.. factory dipped.. on cedar breather.. with attention to flashing..

   also.. keep the trees pruned way back.. they contribute a lot to fungal graowth...

   one thing you can do is install copper strips near the rdige to leach copper down the roof as a fungicide.....

   *Thomas, There was ( is ) a product that is used for wood shingles/shakes called CHEVRON SHINGLE OIL. Runs about $20/5gal. Petroleum based, the few times in the past that I used it it worked pretty well. Lasts about 3 years in our Montana climate. Not to fond of petroleum with wood and had some problems with plants. They do not like the stuff.Use Behr's a linseed oil based oil finish now with good results. Again it lasts about 3 years here. Runs about $90/5gal There are several other brand name products similar that would work. But again the life expectancy with our sun and dry climate is about 3 years.To remphasise Mike, installation is a vital component in wood shake/shingle longevity. Too often builders use solid sheathing rather than skip sheathing under their wood roofs. I have never used CEDAR BREATHER so I can not speak on it's effectivness.Try the cedarbureau for information. http://www.cedarbureau.org. They are helpful and have several good links for roof treatmentswalk gooddavid

   *Thomas I agree with all the above and would add one thing, keep 'em clean and dirt and or debris traped between the shingles ( the waterloo ) will give food for baterial and fungus growth and hence decay. Good Luck!! Bill D. QWC

   *b TVMDCThomas, You should consider "LifeGuard". It is a blend of silicone and rubber which, when vulcanized, waterproofs the wood. That will stop dry rot and should retard the growth of fungus or mildew. Rgds, Bill

   *What if the roof already has moss? There's no evidence of leaking from underneath, in the attic. In the past, I've used zinc or copper strips on new material to prevent moss, but can I retrofit, by sliding a narrow strip under the edge of the ridge cap? Will the copper retard plant growth around the house? Is there a nontoxic or very low-toxicity solution that'll snuff the moss that's there now, and do it quicker than a metallic strip?Thanks for any thoughts.

   The cedar shakes on my house are about five years old. I would like to treat them with a product that would help them last longer and look better. Are there treating products on the market that will last longer than a few years? Treating with Flood products every two or three years isn't practical and can be expensive on a two story house. Any help?? Thanks
