MESA — Over 50 firefighters tackled a massive fire at a Mesa roofing supply company early Saturday morning.
According to Mesa Fire Department, the initial call came in around 2:30 a.m. about a large fire at ABC Supply Co., Inc. in Mesa.
MFD says firefighters had limited access to water supplies, but were able to prevent the fire from extending to any other structures.
Officials say that nobody was hurt in the fire.
Fire investigators said on Monday, the fire appears to have started along the south side of the property fence line from a pile of debris used as a possible warming fire from a nearby homeless encampment.
Winds in the area at the time fanned the flames and spread them to nearby roofing materials along the fence in the supply yard.
It's undetermined if the fire was started intentionally or accidentally. No person of interest is in custody.
A representative from ABC Roofing told investigators that just three days before the fire workers put out a small unattended fire near a similar encampment.
