Serial roofing fraudster to be tried in Yellowstone County

A Montana roofing contractor sentenced for fraud in two counties is now facing accusations of cheating a customer in Billings.

William Lee Dunmire, 51, has been charged in Yellowstone County District Court with theft by deception, a felony, and a misdemeanor charge of deceptive business practices.

Former roofing contractor William Dunmire appears in District Court in Butte on Thursday with his attorney, J.B. Anderson. He admitted to several probation violations and now faces potential prison time.


Dunmire allegedly bilked a woman in Billings out of thousands of dollars by taking money for roofing work and failing to deliver. He was previously sentenced for similar crimes in Butt-Silver Bow and Lewis and Clark counties.

In October 2019, court documents said, investigators with the Billings Police Department responded to a fraud report from a Billings resident. The resident had allegedly entered into an agreement for Dunmire to complete her roof in late August. Dunmire, whose company Peak Roofing was based out of Clancy, told the customer he could measure the roof from his home through GPS, according to charging documents.
