Roof replacement is a large investment, so if it’s possible to renew your roof with a simple cleaning, this can save you a lot of money. But how do you know when it’s time to clean and when it’s time to replace? Today we’ll dive deeper into this question learning about the differences between roof cleaning and roof replacement to help you decide which is the best option for your needs.

What Factors go into a Cedar Shake Roof Replacement?

There are two main factors that go into determining whether or not to replace your existing cedar shake roof. Will a new one will be worth the cost and what are the age and condition of the cedar shingles on your current roof. If they are newer than twenty years old and in relatively good shape, then a simple cleaning can usually restore them to their original beauty. However, if your roof is over twenty years old or it needs a little more TLC, then you may want to consider a roof replacement. It is always worth contacting an experienced cedar shake roof cleaner to get their opinion on the condition of the roof. The quote will be free but their knowledge is priceless.

Where do You Live?

The age of your roof isn’t the only determining factor when deciding between roof replacement and roof cleaning. If you live in an area where your cedar shake roof has to deal with extreme weather conditions, like snow and rain, then this can also cut down on how long it takes for your roof’s condition to deteriorate. If the average rainfall during the winter months is over 60 inches, then chances are that if you have a cedar roof, you’ll need to consider a roof replacement much earlier than normal.

The Surrounding Environment

Another factor that comes into play when deciding whether or not it’s time for a new roof is the overall condition of your cedar shake roofing. If all your shakes are falling off or there are large chunks missing, then this can cause problems for you over time. If you’ve noticed that your roof doesn’t look quite as beautiful as it once did, then chances are that you should consider a roof replacement for the safety of your family and home. It is worth noting that you can get a quote for a section of the roof to be replaced and have the rest cleaned. If you have two broken cedar shakes or shingles then there is no need to remove the entire roof.

Typical Lifespan

When deciding between roof cleaning or roof replacement, one thing to remember is that no matter how hard you try to keep your cedar roof looking perfect, it will eventually need to be replaced, the typical lifetime of a maintained cedar shake roof is 40 – 50 years. A cedar shake will last for years and years but external factors play a large role. The natural elements and dampness will cause it to rot and deteriorate over time, this can be brought on by algae, fungus, moss, or other organic materials collecting on the roof. However, you can get a lot more life out of your roof if you take some preventative measures such as a clean every 5 – 10 years, creating a gutter system that captures debris and water, and making sure trees are not dropping lots of leaves on to the roof which accumulates and cause the cedar shakes to deteriorate.

Overall, roof replacement is a large investment and if you don’t have to do it, then we always recommend that you don’t.

What can I say? Bruce and Keith provided an exceptional service, and they are really nice guys too. Found out at the 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. The place looks outstanding! Highly recommended.

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.
