Four years ago, i had gutter gards installed on my gutter system. By design, the guards had a tail "skirt" that was pushed up under the starter shingle of the roof. Two years late, i had the roof replaced. The roofer installed the ice-water shield OVER the top of the gutter gaurd skirt. Now it's time to remove the gutter guards in order to clean the debris out that got into the gutters - but i can't do it because the guards are glued down under the ice/water shield!!??..The guy ibought the gutter guards from said it's the roofers fault for not installing the water shield UNDER the guard skirt. the roofer says they had to do it that way in order for run off in case water gets under the shingle higher up the roof. A 3rd pary tells me that water shield MUST be installed directly to the decking, all the way around over the edge where the fascia board is (with nothing in between them)- all B4 the gutter, drip cap or gutter gards are installed. who's right??
