What type of siding lasts the longest?
Depending on the weather in your area, different options can last longer. Vinyl and steel siding will typically last 50 to 60 years, which is on the higher end of the lifespan for siding. Because LP Smartside is newer, there is not a specific estimate for how long it will last. However, with the wax coating over wood, it should last from 40 to 60 years.
