There is a big debate on the benefits of oiling a cedar roof. A comprehensive and great research paper was written by OSU students, referenced in EC1271, September 1988. Their exhaustive research neither discounted nor encouraged oiling of cedar roofs. As stated in EC1271, originally Cedars mass only contained 3% of its weight in oil. With such a small percentage of its weight to begin with being oil, the debate on replenishing is faulty.
We are not stating that the oils should be replenished. We are advocating oiling a roof in Seattle to prevent rapid expansion and contraction caused by UV rays and rainwater. The stress of shrinking and enlarging cause wood to crack, it is our belief, that oiling a roof stops the expansion and contraction from causing damage to the shingle. The oil allows natural contraction to happen without stressing the wood it is applied to.

When deciding to oil your roof, it should be done from the day it was installed. The ability to repair a cedar roof once the damage has been done is nonexistent. Maintenance is major issue for wood roofs. There are ways to treat cedar for moss that differ greatly from the way we would treat a composition roof. On average a 1200 square foot roof area costs from $16,000-25,000 dollars, according to homewyse. Yearly maintenance can run you about $400. When deciding to buy a home with a cedar roof or having it installed, budgeting for maintenance should be the first thing you do. The unexpected result of not maintaining your roof, can seriously hinder your economic circumstances.
