Ontario's winters and panel choice
Metal sheds Ontario's snow in a sheet rather than holding it the way shingles do, which changes where it lands below the eaves.
That's exactly why snow-guard placement matters more on a Ontario metal roof than on one in a milder climate.
Data: NOAA National Centers for Environmental Information, U.S. Climate Normals 1991-2020 (annual/seasonal and monthly, by station) (1991-2020), from the nearest NOAA station 1.4 mi away.
What federal hazard data says about Ontario
Wildfire risk near Ontario rates Very High on FEMA's county-level index.
Metal itself doesn't burn, but a fire rating on a Ontario roof still depends on what's underneath it: the deck, underlayment, and any insulation in the assembly.
That distinction is worth understanding before you assume metal alone solves a Ontario property's wildfire exposure.
