SLINGER -- Like a dentist looking for a cavity, contractors needed to be up close to find what they're looking for.
And if left untreated, it could hurt a lot more later.
"We're looking for holes in the shingles, or fractured matting as we call it," roofer Anthony Walsh explained to TODAY'S TMJ4. "If the whole gets bigger, that's how you get a leak in the roof."
Hail hammered parts of Ozaukee and Washington counties on Monday, with some ice balls similar in size dimes and quarters.
Walsh, a contractor with Durashield Roofing, visited nearly one dozen homes and businesses on the Highway 60 corridor in Slinger.
He says other things he found included "dents in gutters or down spouts, holes in siding, and dents to HVAC and stuff like that."
Walsh's advice to homeowners is to call a contractor to inspect their roofs and siding after a big storm, and have them take pictures of any damage for insurance claims.
