OT Roofs Leaking

[The Funster]

I swear, I'm gonna rip the gutters off of my house. Go to Vermont or New Hampshire and they have no gutters for just this reason. Their houses might be on slabs or have dirt basements though. Still, I may just rip em all down in the spring.

I wish there was a magic formula but each roof and house presents different scenarios. My wife wanted a light house so we got the skylights. Building new again, i don't put them in, but do a lot more of exterior window glass instead.

I am considering putting spray foam insulation into the roof rafters. Attic is 0 degrees in winter, and 120 in summer, but the foam would cap the attic temp at 10 more than the 2nd floor temp in summer /10 less in winter. Also remove any ice issues. Could be BS about the ice dams? Anyone have any experience with spray foam?

Do you have insulation in the ceiling below the attic space? You only want one insulation perimeter. I've contracted spray foam and been on projects that have had it done. Most have had really good results, but one (not my responsibility,TG) ended up a disaster.

You can put a gutter equivalent in the ground. Essentially a french drain at the splash line. Slightly sloped perf pipe covered with gravel. The gravel scatters the splash so you dont end up with a nasty mud splash on your foundation/watertable/first couple courses of siding.

Skylights are "the mother of all leakers". Maybe people have another roof dumping water down on the roof with the skylight and it is damed and backing up under the shingles. Maybe heat is escaping from a poor insulation job around the skylight. If the skylight is step flashed correctly it should not leak in a rainstorm but with ice dams it is another matter. Open up the skylight all the way and lay pantyhose filled with salt or ice melt on the snow on the sides and bottom of the skylight. It is probably not possible to get anything right across the top of the skylight.

Yes - have min fiberglass sheets (50 yrs old?) on attic floor / 2nd floor ceiling. That will be removed. Attic is only ~6' high at the ridge beam - attic houses only the ac fans. The gable and roof vents would be sealed.

On the radio they said to buy pure calcium chloride, put it in a nylon stocking and put it inside the gutter. That will melt ice dams.
