Mikel Wallesen
Owner, Big Red Roofing

Mikel took over his family's roofing business from his father and now runs Big Red Roofing. He explains the work, job by job, on the Big Red Roofing YouTube channel.
In Mikel's words
“In the process that we have to replace all the tile, we try to never leave a customer's house roof exposed overnight. Never know with climate, you never know with weather. So, we want to make sure that everybody's protected.”
“Most people think you have to replace a whole roof, but in terms of the tile, depending on the underlayment, some people can only afford a partial re-roof.”
“What happens in the state of Arizona, the underlayment dries out throughout the process of the 30 years.”
“We take all the tile up, making sure our crews understand if this tile can be purchased or if we have to save as much as we can.”
“The reason we put the coating on, as I've said in prior videos, is the spray foam is not a UV protectant.”
