Low slope roof


I have a 1 year old roof, 2x8's 24"oc. No ridge vent and ice & water shield on the entire roof. Until about 3 weeks ago there was no problem. Now I have some water coming out of the window trim. Window trim is PVC and windows re foamed in with minimal expanding foam. Entire attic is insulated with R38 fiberglass. Ceiling has had vapor barrier installed and all openings have been tuck taped. No staining on the walls or ceiling, no visible mold but I don't want any either.
Thanks

Pictures please.

Why would anybody install I&W over the entire roof? It can't breathe.
I just re-read that. How lo-slope?

The slope is 2.1/12 pitch. I looked at venting the ridge but was worried about rain/snow finding its way in. Not sure how to post a picture but I'll try to figure it out. Thanks.

You will need to host the pictures via an online resource and then post them via hyperlink.

Thanks

Low slope roof


That is super low pitch for asphalt.

Where on the window trim (top, bottom, side, etc).

If it is a roof leak, it will normally show at the header and in the drywall at or above the windows where it hits it.

Is there drip edge on the roof? Gutters?

that low a pitch, an accumulated leak in the roof would also shop in the drywall in most cases as the problem with the water shedding is for the entire low slop section.

The leak is on the top of the window. Above the window and below the header. There is drip edge and no gutters. I didn't want to stop water movement, due to the low pitch, so that's why no gutters were installed.
Thanks

Hang a gutter with no end caps. Sounds like the water cascading off the roof is blowing back into your window. Did you have a high wind with the last storm?

You may want to double check the flashing details used on your windows and siding. Done correctly, a pressure washer will have trouble making a leak.

Pull the siding and check the window flashing and you really do need a gutter on that roof and especially given the low slope and lack of velocity coming off that roof.

Thanks W o W. That's what my carpenter buddy told me today. Take off top 3or 4rows, cut tyvek and check for infiltration. Then tape with buytle tape. Hope I can find it.

Thanks
Dave

The buytle tape without the metal flashing will be a temporary fix. Take a closer look at the flashing details in my link above.

Don't rely on the tapes alone as they do fail over time and especially if they are regularly getting hit with water.

That roof needs a gutter/drip edge combination for certain.

That metal flashing looked to be 8 or 10" wide. I couldn't see if it had a lip or not. When we put the dormer on last year I had a contractor friend of my son help with the ridge beam. He said to not install gutters as I would want the water to get away from the roof as fast as possible. Gutters will make life easier for people entering the house. The past week was the first time we have had any water issues.

Which piece? The ones under the window sides? The ower lip of the window? Did it also 'lead' out from under the siding? Or just add to the flow under the siding?
