Hi. we recently installed a classic metal ribbed roof over our old shingle roof. Unfortunately, I was too ignorant to know that it would be better to do the gutters before finishing the roof but now I want to replace our 4" gutters with 6" gutters due to the increased rain flow. There are two layers of drip edge, the one from the shingle roof and the new one for the metal roof. One gutter installer told me there is a 1/2 " gap between the drip edge and the fascia board, and said the only way to install K style gutters is to add 1/2 inch of fascia board all the way around the house before installing the new gutters. This would cost a lot of time and money in addition to the gutter install job. I'm trying to find a less labor and cost intensive alternative. Forgive my ignorance but would any of these work? 1) Use long screws and dont worry about the gap, or put a block behind the drip edge in the places where the gutters screw into the fascia, 2) I've seen photos of gutters online with a plate that fits unter the metal and screws into the rafters, rather than the handing brackets that go into the fascia - could we unscrew the bottom of the metal roof and slip something like that underneath then screw through both? Not sure if that will work with k style gutters 3) install the gutters with roof straps, but this would make it difficult to use gutter guards, which are a must because we have lots of pine trees in the yard which would quickly clog things up if there wasnt a cover. Or, should I bite the bullet and install the fascia everywhere then go with traditional hangars. Thanks in advance for your ideas!
Thank you for buying a metal roof. I must be missing something but I am not sure why they wouldn't still mount gutters to the fascia, putting the back wall of the gutter behind the original drip edge. You want to make sure that water coming off the drip edge goes into the gutter, not behind it. If you do anything else, I strongly urge you to consult with the roof installer as the wrong move now could compromise the roof performance.
Thanks Todd for the quick reply. My boyfriend said the same thing. "There are gutters on now that they would be replacing so what's the difference." It sounds like the contractor is creating a problem that doesnt exist. There is one section over the back porch where the roof overhands 3 inches instea of 1 like the rest of the house. I think the contractor through the roof would hand too far out into the gutter and putting extra fascia would solve the problem. But I think it's only the case in one small area. I appreciate your comment.
There can be issues sometimes with water overshooting gutters but your bigger gutters will help. To me, there are far greater risks if the drip edge falls behind the gutter rather than leading into it.
I've had a few more gutter estimates and learned a little more about the issues.
Here is how different contractors have said they would deal with it
install an additional 1/2 inch of fascia board around the whole house, the idea being that the gutters can be installed low but will stick out far enough to catch the water
install 7" gutters instead of 6" gutters which are WAY more expensive - the idea being they can be install lower and still catch the water.
3 Install 6" gutters and cut the two drip edges at every place where a gutter bracket will be installed, which will be very time consuming and therefor WAY more expensive than a normal job, according to them.
So far #3 sounds the most realistic and we are considering doing it ourselves to save the money.
We've also done some research and understand gutters can be hung from the roof using a strap, but none of the gutter contractors in our area will even discuss that possibility. they only use the standard brackets. Also, this would prevent us from using gutter guards which is not an option with all the pine trees we have, unless there are special guards for use with the straps, which I haven't come across.
I've also seen photos of gutters attached to a metal plate that gets installed unter the metal roof, which would be easy enough to unscrew then rescrew with the plate attached to the gutter. But I havent seen those for sale anwhere.
At this point, we're preparing for hurricane season here in Florida and trying to decide what our best options are. Any additional advice appreciated.
The above is one bracket I like. I would not use straps that mount on the roof plane. In determining which way to go, there will always be times when water shoots over the gutters, in my opinion. You need to keep in mind that water could come down from beneath the metal panels. That is not ideal nor is it something that always happens but it can happen, especially on more complex roofs where you have flashings that may bleed some water on occasion. I'd be careful to try to make sure that water ends up in the gutters, not behind them.
Ok. Thanks again
