Firefighters battled a three-alarm blaze at a tire and automotive business on Elm Street West Haven Friday morning and the fire spread to a car wash as well.
Officials said flames tore through Reliable Tire Auto Service and quickly spread to the Blue Ribbon Car Wash around 12:30 a.m.
"The tires are petroleum based. It's just a hot fire. It's hard to put them out. You need large volumes of water," Deputy Chief Ed Sweeney, of the West Haven Fire Department, said.
Heavy damage from the fire caused the roof of the building to cave in and officials said the tire business appears to have been destroyed.
Crews were able to contain most of the fire to the tire businesses
No injuries are reported.
New Haven and Milford fire crews were called in as mutual aid for fire station coverage.
Elm Street was closed at the Kimberly Avenue Bridge and at 1st Avenue but has reopened.
The fire marshal will investigate the cause of the fire.
