I have a metal A-frame roof on my barn... right now the snow just slides right off (no shoveling required). But I want to add gutters in the spring... which in my mind will prevent the snow from just "sliding" off like it does now with no gutters (in percy's photo it looks like that's where the snow is getting stuck at and piling up). Would it be better to just leave without gutters? Seems like a lose/lose.
Gutters are horrible without the snow pegs to hold heavy snow up to melt and not slide...that is what kills your gutters!
But those pegs make cleaning your roof in really heavy snows harder.
I do not have them but I have wanted them for some time. Yesterdays job would of been much harder if the barn had them.
