[color=#383a3b]I need to have a new aluminum gutter and fascia/aluminum/wrap replaced on the upper story of a two story colonial with total 2200 square ft floor space. The gutter length is 28 ft on this part upper story with a 5/12 pitch roof made of asphalt. This spring I will have all the gutters replaced along with the roof. This upper gutter needs the repair now, since it pulled away from the rotted fascia.[/color] [color=#383a3b]One of the gutter contractors will only quote a 6 inch K gutter, since he claims 5 inch K gutters are not used much anymore and the 6 inch will flow much better. Present gutter is 5 inch with a slot type gutter guard. I am located in NJ as far as rainfall. I read that there are cons to the 6 inch one of which is the are heavier, more expensive, large appearance and required better fastening to the facial/rafter tail. Which size gutter do you recommend ?[/color]

We just discovered unfortunately a water leak in our roof, which is 7 years old. The water accumulation has been adjacent to the ceiling where a skylight sits. I went into the attic and took some video of the roof in that area, and I believe it shows the water damage along the interior decking. Here are some screenshots: [img]https://cimg2.ibsrv.net/gimg/www.doityourselft.com-vbulletin/715x1271/black_stuff_f845e57d66798d6ebedf7e959c9226c4c8f02fe8.jpg[/img] [i]Blackened area between rafters is probably not a good sign.

Any thoughts on where the leak is coming from? Are there multiple leaks? The roof should be under warranty from our builder.
