Grigg I am concerned as well about the 29 gauge..it seems to be the standard here..seems like heavy foil...
I wonder how something that thin holds up to hail out west(not an issue here, very rare - we get hurricanes...)My buddy bought a Porsche Boxster cheap in Alberta due to hail damage, and the car looked like a golf ball! He got a lot of the dents out but even that metal was a lot thicker than 29 gauge roofing....
