I suffered hail damage to my roof. What should I do next?
Northern Colorado is a lovely place to live, but it is one of the regions most prone to hail. Hail can cause damage to siding, gutters and unfortunately your roof as well. Once you suspect hail damage, it’s important to start the roofing inspection process as soon as possible to avoid further damage that could lead to a possible roof replacement. Also, you’ll want to start any type of insurance claim process.
