Return to I Have An Existing Metal Roof and Have A Question
Return to Forum
We purchased a house last year with a metal roof. The roof is wedge shaped with a slope only to one side. There was no eavestrough so we had recognized gutter company install a 5", one piece, full-length aluminum gutter the entire 86' length of the roof line with a downspout on each end. Rain and dew seems to seep in behind the gutter and leaks from numerous spots. There doesn't appear to be any overhang of the metal roof beyond the facia.
My main concern is the leaking on to the deck, causing wet spots. The gutter company used a silicon sealant the entire length of the eavestrough, where the gutter backs against the facia but that hasn't stopped the issue. Is there a way to prevent this seeping? Would a gasket of some type in between the gutter and facia work?
Thank you in advance for any help you can provide.
I would see if the / a roofing contractor can install a drip edge that hangs down the fascia but goes up under the underlayment on the metal roof, and then goes into the gutter. That should capture everything and direct it into the gutter.
Thank you Todd for the quick response. There already seems to be a metal strip that extends about 2" to 3" up under the roof and over the fascia. See photos. It looks like silicon was used between the metal strip and the underneath side of the roof to try and seal the edge of the roof line, when the roof was installed about 15 years ago. This has deteriorated over time and the metal has lifted slightly at the edge. Most of the silicon you see in the photos was applied when the gutter contractor installed the eavestrough last summer. What's the proper way to seal the edge of the roof line? You may have noticed in the photos as well that some of the fastners are broken/bent. Should the broken/bent fastners be replaced? Should the top of the fastners be coated with silicon? I have questions regarding the snow guard, which I will post separately.

Thanks. Has the gutter been mounted in front of the drip edge rather than behind it? The back wall of the gutter should go behind the drip edge, so water coming off the roof and drip edge feeds right into the gutter. Any fasteners not sealing well and seated squarely against the panel should be replaced or perhaps tightened.
It's hard to tell now if the gutter is in front or behind with all the silicon. Will have to get the contractor to remove and ensure it is re-installed in behind. I can get the contractor to replace and or tighten the fasteners as well. Thank you for your help again. Much appreciated.
