Installing a Gutter on an EPDM Roof


WoW, I really like the tapered insulation board idea - thanks! I suppose the term-bar in addition to the edge metal may be considered over-kill, but if the EPDM wraps down and around the fascia enough it will be below the gutter and not behind it. . ... hmmmm, maybe my fascia board is not wide enough for the term bar to end up below the gutter ... I'll have to go take another look. Thanks for your ideas. I will take all into consderation. This is a very helpful forum!

Installing a Gutter on an EPDM Roof


The EPDM shouldnt go past the bottom of the gutter, (eye sore). I forgot a response to your Box gutter/ Drip egde. We shop form all of ours. Any flat roofer should have a sheet metal brake to do this. I could make some and send them to you but I have a feeling you wouldnt like the shipping costs on a 10' item. To get an idea of he gutter were talking about it would be the "boxed gutter flanged" http://www.rutlandguttersupply.com/g...utters_Box.asp

Installing a Gutter on an EPDM Roof


Thank you both very much for the information and links for the gutter. I am definately going to try to get some, if at all sold locally or if I can find some one to fabricate it. Indeed, shipping would be too much. I wish you all lived closer .. I would hire you in a heartbeat. You sound like you really know your stuff. I hope I can find someone who understands flat roofs like you do. Thank you again! Linda

The EPDM gutter detail is baby shoes I mean if the roofer is going to install a fully adhered tappered roof system. And then he needs to be instructed on how to do a gutter. Really ???. If he gets that far with out screwing it up I think he's good to go...... Just saying

Installing a Gutter on an EPDM Roof


You make a valid point, however, I've interviewd a half-dozen contractors and NONE of them considered a tapered iso board, and NONE of them suggested the self-flashing gutter, and only half of them were willing to install the EPDM down the fascia (the other half insisted the 'right' way to do it was to install the epdm up to the edge of the roof and install a metal drip edge there). I've seen where that way is acceptable, but then read where the wind lifted it up, and it was better to have the edpm go down over the fascia. Some guys just did not want to do it the other way. One roofer said that if I didn't want the ice in the gutter to freeze and get under the epdm, then don't install the gutter .... not the solution I was looking for. I hope I hire someone who 'gets it" as well as you!

Any recommendations iin the Connecticut area? Tough since it is only 26 x 22, but I am also re-roofing the shingled area, and building a 10x12 pt deck in the back.

Thx, Linda

Installing a Gutter on an EPDM Roof


That's the problem. You've interviewed contractors, not roofers. Or maybe shingle roofers, not flat roofers. Or maybe salesmen for roofing companies that don't understand the products they are selling.

Point being WE do not make these things up as we go along. If we did we wouldn't all be saying the same thing. A professional roofers has likely read a spec book or looked at a detailed drawing or worked under the tutilage of someone who has.


Have you tried contacting the National Roofing Contractor's Association www.nrca.net or the National Roof group www.rooferdata.com ? A member of the NRCA will likely understand basic details such as a gutter because when they join they get the roofing manual free of charge.

Is a license required in your area to be a roofer? If so don't even think of hiring someone with out it. You may also check into the certifications of the roofing contractor. I truly feel that a professional roofing contractor will have at least some certifications. Certifications don't make you professional, but they don't hurt either.

Installing a Gutter on an EPDM Roof


Yes, I will have the torch-down roofing removed down to the plywood, install 1" ISO board, EPDM roofing installed under the shingles (which is also getting torn off to the plywood and re-roofed) and the EPDM will go down all 3 sides' fascias. I think I'm starting to 'get' this. Thank you .. .. thank you all!

Well you can and you cant. If you buy the ones like say online you really cant. If you have someone make them, and they are good sheet metal people they can build the slope in to the profile. Also it depends how long the gutter is. Say 20' I wouldnt bother making a sloped gutter. 40-50' Yes of course. You could do a regular K style and do a normal drip edge. If the EPDM is behind the gutter ont he fasica and back side of the gutter covers the EPDM you wont have to worry about Ice damns.

install gutter with a few nails to the facia just to hold in place. Caulk the back of the gutter, and then term bar the epdm into the caulk, with screws and hidder hangers????

Installing a Gutter on an EPDM Roof


Linda if you look at my website Commercial Box Gutters you will see the back of the gutter is higher on one side than the other. Well maybe it's not incredibly obvious because the gutters shown are short but, the pitch is bent into the gutter when the gutter is fabricated. This is truly a custom gutter for each building, our fabrication shop will typically build 2-3" of pitch into a average 24' gutter.

1985 is right you can use a regular gutter, but it's much more difficult to use the shingle roof gutter (k style) on a flat roof. First the rofo membrane would wrap the fascia, then the gutter would be installed, then a strip of membrane sealed to the roof and wrapped into the gutter, then a termination bar in the gutter. It'll work, but alot of extra work.
