Why is a Clean Cedar Roof Important?

Discover with Bruce

Cedar shake roofs were a very common roofing material in the early years. One of the first roofing materials in the country. Cedar has its own natural preservative element. On average a cedar shake roof can last 40, 50 to 60 years if maintained. Depending on the grade of the cedar shake.

Cedar shakes are expensive to install and they tend to have higher insurance coverage for that reason. They also are the best insulating roofing material as they hold the ambient temperature within a home better than any other. Thus a saving in heating and cooling cost.

The one factor that many homeowners of cedar shake roofs are never told, is that they need to maintain a shake roof in order to reach its full lifespan potential. Again, they are organic in nature, like one’s teeth, which are also organic and need to be maintained.

Cedar Shake Roof Cleaning Minneapolis

What can I say? Bruce and Keith provided an exceptional service, and they are really nice guys too. Found out at last minute they were in Minneapolis, and they fit me in for a cedar shake roof cleaning the next evening after their regular job was done. Even cleaned up my gutters, small fence and small deck at no charge. Place looks outstanding! Highly recommended.

Cedar Shake Roof Cleaning, St. Cloud, MN

I highly recommend this business. Due to the work performed we are going to get another 10-14 years out of our cedar shake roof. We were told by some roofing companies that the roof should be replaced in 2 years. I lucked out and found Sullivan Roof Cleaning while researching companies that perform this service, and was pleased to learn that the company does work outside of Iowa. If you need your cedar shakes cleaned, go with Sullivan Roof Cleaning.

Cedar shake roof cleaning Kansas City, MO

Bruce did a great job cleaning the whole exterior of my house. The roof has new life! It looks practically brand new. All the mold and moss on the roof, on the gutters, under the eaves, completely gone. He exceeded all our expectations. When he tells you what he can do for your house, you can believe and trust him. Great guy, great service.

Cedar shake roof cleaning Kansas City, MO

Mr. Sullivan cleaned our roof that had not been maintained in 28 years. The roof appeared almost black, but after the cleaning the shingles were a beautiful light brown color. It really brightened out home. Knowing that the deterioration was stopped with this cleaning was wonderful news. I love my shake shingles and am so thankful for Mr. Sullivan's service to keep them healthy and long lasting for years to come. I feel the cost is a wonderful deal for what you are doing to preserve a beautiful roof. Mr. Sullivan was right on time and came all the way to Kansas City within just a few days of my initial request for an appointment. We was very professional and left our property better than he found it. Thank you, Mr. Sullivan!!!
