Janesville Siding Takes a Lot of Hail
If you’ve lived in Janesville a while, you’ve probably had your siding hit. Rock County has logged hail every year since 2010. On August 16, 2025, NOAA storm reports showed ping-pong-ball hail on the west side of Janesville. Earlier that year, on April 18, 2025, baseball-size hail fell near Edgerton and Evansville the morning NWS Milwaukee issued its first-ever “destructive” severe thunderstorm warning.
Hail that dents a car will crack vinyl, especially older vinyl that’s gotten brittle in the cold, and it leaves round dents in aluminum. That’s the main reason we spend more time talking about James Hardie with Janesville homeowners than almost anywhere else we work.
Vinyl vs James Hardie for Hail Country
James Hardie fiber cement is a dense, non-combustible board that stands up to hail and impact far better than vinyl. It has the look of painted wood and suits Janesville’s older homes. It costs more up front, and it’s backed by James Hardie’s own product warranty.
Vinyl siding from Mastic and Norandex is still a great choice for a lot of houses, and it’s the budget-friendly one. Thicker and insulated panels resist dings better than the thin stuff from decades ago, and installed right, vinyl often lasts 20 to 40 years. If a few panels do get hit, they’re quick to replace, as long as the color is still made.
That last point matters. If your current color has been discontinued, a hail repair may not match. We’ll tell you straight when that’s the case, and when the rest of a wall or the whole house makes more sense.
Courthouse Hill to the East Side
Janesville’s older neighborhoods, like Courthouse Hill and the streets near the Rock River downtown, are full of houses that are a century old or more. They’re tall, with lots of corners, porches and trim, and they often have wood siding under newer layers. Those jobs take more prep and more careful trim work, and Hardie’s wood-like profiles tend to fit them best. If your home sits in a local historic district, let us know. We’ll check what review applies before we order anything.
The east and north sides have more mid-century ranches and newer subdivisions. Those are simpler houses to side, and most siding jobs there take 1 to 2 days.
On every house, the old siding comes off first. We handle removal of any old siding, asbestos included. We repair soft sheathing, and most jobs get new house wrap. We install in winter too.
Storm Damage and Insurance
After a storm, we’ll inspect your siding and roof for free, photograph and measure the damage, and help you with your insurance claim if it’s worth filing. If it isn’t, we’ll say so. See hail damage repair.
What Customers Say
“After a recent hailstorm caused significant damage to our roof and siding, we reached out to Jeff Smith with Martin Exteriors, and we’re so glad we did. From the very first inspection to the final cleanup, Jeff and their team were incredibly professional and easy to work with. What really set Martin apart was their excellent communication. Jeff kept us informed every step of the way, clearly explaining the scope of the damage, the repair process, and working closely with our insurance.”

Janesville Siding FAQ
