Storm chasing contractors might be headed to town to take advantage of your recent hail storm damage.
KSFY News spoke with a local business owner who told us what signs to look for when hiring a contractor.
There are a few red flags which can help you spot a storm chasing contractor who might not be legitimate.
Before you hire anyone, there are some things you can do to see if you actually have storm damage to repair.
Last Thursday's hail storm has many Sioux Falls homeowners looking for contractors, and some roofing scam artists looking for willing victims.
Terveen Roofing and Construction owner Mike Terveen said "I've heard horror stories from other storms and the oldest trick in the book is the money down and we'll be back. Then you never see them again. I wouldn't give anybody any money down. When we do all of our roofs, we don't ever get payment until the roof is done and you're 100 percent happy."
Terveen is an experienced contractor who also advises what signs homeowners should look for on their roofs.
"One of the tell-tale signs that you have roof damage is the metal vents up on the roof. Whether it's the box vents for ventilation or the storm chimney tops, they're made out of metal and if there are little dings in them, it's an obvious sign that you have damage," Terveen said.
Besides finding rocks in your gutter, a damaged roof may be hard to see. Homeowners should file an insurance claim or get a free inspection.
"If you get hail down, and you don't do anything, it might look fine for a couple of years, but then three, four, five years down the road, it will start to curl up and that's when you'll start to see the signs that you have hail damage and maybe didn't know it," Terveen said.
One homeowner warned others about storm chasing contractors who may come from out-of-town and go door-to-door looking for easy money.
Mitchell homeowner Vance McPeek said "different people I know had gone with people that were out of town, from different parts of the country. I'll tell you what, they learned their lesson the hard way."
"Local guys, we're a phone call away and we can come by in a year or two if you ever have any issues. We're always here and they're always gone," Terveen said.
If you ever feel pressured by a contractor, you might want to choose someone else do business with to handle your repairs.
And before you hire a contractor or take your car in for hail damage, check with your insurance company first, and file a claim.
State Farm Insurance told us they were planning to bring in a national team of claims adjusters to Sioux Falls Monday, but the recent hail storm in Blair, Nebraska has created a backlog.
They expect to set up inspection locations next week.
