I have a 5" gutter 55' long with a downspout at each end. The high spot in the gutter is not in the middle, it is about 3/4 to 1/4 so most of the water goes to the south downspout. My downspouts went into tile buried in the ground that runs under my drive. The tile is plugged with tree roots so I run the downspouts into the yard. The problem is the north downspout runs across a side walk so it is in the way. I am thinking of raising the north end of the gutter so all water runs to the south downspout and going to a 3"x4" downspout which is rated for 434 gal/min. and running into the yard. I have approx. 1200 sq. ft. of roof going into that gutter. I read where 1 downspout is recommened for every 20' of gutter. But going with the bigger downspout, It sounds like this should work? Any input will be helpful, Thanks

We just had a shed built in our yard, and they put asphalt shingles on the roof. I have noticed that the shingles are not totally flat. They tend to bow up slightly (about 1/4") in the center of a typical 1 1/2 foot piece. They are a type of architectural shingle, though not especially heavy or thick. I thought there were nails underneath that were pushing them up, but there is nothing. When I push them down, they go flat, but when I take my hand off, they pop up again. With the sun, etc, will they eventually lie flat? It is most noticeabale on the ridge where some of the shingles are sticking up a fair amount. It is getting cooler here in CT, but we should definitely have a few more warm days with direct sun. Thanks. Dave
