The fire was reported about 7 a.m. on Thursday morning.
When firefighters arrived they saw flames coming from the roof of the home on Blythe at Dayton.
Two adults and two children told fire officials they first smelled burning rubber before seeing the flames in the garage.
By the time fire crews were on scene the fire had gotten into the attic and the roof collapsed leaving firefighters no option but to fight the flames from outside the building.
No one was injured, but the home is lost. The family is now getting help from the Red Cross.
Officials said they have the road between Shields and Dakota closed while they investigate. The closure should last a couple hours.
