Ballman understands a complete roof replacement can be expensive in labor and materials. Their team can assess your situation to see if restoration may be a better option. It's an option worth looking at. Commercial roofs can last typically 20 years, restoration can add 10  to 15 years to that roof's life. Plus there are tax benefits, as roof restoration is classified as a maintenance expenditure (replacing is considered a capital expense.)  

Ignoring the fact that your roof is deteriorating doesn’t make the problem go away; in fact it will only get worse. Find out sooner than later if restoration is an option for you.
