Hey guys .....I have a metal corragated roof not to much of a pitch...i think its a 2/12 pitch.. the chimney is on the lower part of the roof...Im just wondering if i should put something up there so the snow and ice sliding down the roof doesnt hit the chimney and damage it..I've only had the chimney up there for half the winter last year and havent had any problems yet...just thinking about it now...any ideas what i can put up there ? thanks
