Cedar Roof Oiling is it Necessary?

pdf-flatThere 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.

OUR PREFERRED PRODUCT | WHY WE USE CHEVRON SHAKE OIL

chevronChevron shingle oil is a superior product for oiling cedar roofs it is of low velocity and transparent. The application doesn’t change the appearance of wood; instead it gives the wood a wet look.

Although higher in price than other cedar oils, the history and its long-established reputation among wood restoration experts make it possibly, the best choice for oiling a cedar roof or fence. 

There are many benefits of Chevron Shingle Oil such as:

  •  Its established reputation.
  •  Its ability to mix well with solvents.
  •  Its lasts when applied: many homeowners have said their oil treatment lasts 5 years or longer.
  • It’s easy to apply. A backpack sprayer with a round tip or flat-headed tip work great. There is no need for paint sprayers.
  •  Its ability to be mixed with stain.

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.
