HOW LONG WILL YOUR RESTORED ROOF LAST?
A very common question we get when telling someone about roof restorations is, “How long will the restored roof last?” This is a great question and one that should be asked when considering a new roofing product. We have an answer to this question that we think will make any potential roof restorer happy.
Industry Average Lifespan
Most roofing systems provide a useful life between 15-25 years. Some last longer, some not as long. The average of around 20 years is a good rule of thumb. When you install a restoration coating on your building, the longest full system warranty we offer is 20 years. Of course, we also offer 50 year material-only warranties because our confidence in the coating is greater than our confidence in some existing roofs. So, your roof is fully warranted for 20 years with a restoration coating, right at industry average.
How Long Will Your Building Last?
The 20 year lifespan of a restoration coating is just the beginning, though. Every 20 years, you can recoat the roof to receive 20 more years of protection. This process can be continued indefinitely as long as the building remains in good structural condition. So, the real question is not how long a restored roof lasts, but how long your building will last? The expected restore roof lifespan is basically as long as the building should last. This doesn’t mean one coat and the roof will last forever. You have to recoat every 20 years which takes time and money, but by recoating once every 20 years you can extend the life of your roof indefinitely.
Because a restored roof behaves a little differently than traditional roofs, the expected lifespan has to be defined differently as well. Other roofs last 15-25 years and then they are done, they must be removed (unless of course they’re restored). A silicone restored roof can continue to be restored again and again, extending the life of the roof.
