It is not a crack , it is where the 2 pieces of gutter are joined. Crossroads employees (along with other companies) install them from the rear forward not taking into account where he joint will be. If it was installed from the front toward the back ,the leak would be somewhere oblivious.
Christian ,are you listening .? Have the guys install where the seam will not be over the door,I know different models have different door locations, but common sense should out do getting done early and going home early and producing a problem that should not be there
Scott , get a candle and rub the underside of the gutter with it for a temporary fix until you can put some caulk into the inside.
It was a rainy few days at Algonquin Prov park...tarps kept us dry.
