Unsolvable Rain Gutter Problem
bkruppa

I had a lenai added to my home and as a result of the new roof lines I now have a rain gutter problem that no one seems to know how to fix. The problem is that 3 roofs now feed to a trough at the bottom of the roofs and then exits out to the edge of the house and into the rain gutter. During a heavy rain storm there is just too much water for the gutter system to handle so it overflows and then comes into the lanai. One roofer built a large back splash to contain the water but this didn't help. Another roofer built a large collector box to capture the additional water but that didn't help. Another roofer passed on the problem. My suggestion is to just place a chute at the end and let the water shoot out into the shrubs below. Not a good looking idea but if it works I'm not concerned about looks. Any thoughts on this problem? If anyone has a solution we can get together through email and I can send pictures of the problem and current setup.

change your settings to allow private messages. or send me a message with your email address.

Need photos, at least a few to fully grasp the situation.

While I agree that everyone should have their PMs set, it is ill-advised to take the discussion away from the public forum.

To post pictures, you have to upload them to a photo host, then link them here.

To me, it sounds like they've channeled all the roof water to one spot, which is incapable of handling it. Probably why most roofers can't fix it is because they can't do custom metal work, what you likely need is a company that does architectural metal work that can fabricate a larger gutter, collector, and downspout to handle the increased flow.

Yes, spruce is correct, you have a "bottle neck" of rain water and the way to fix it to add more spouts, install the gutters to force the water into the additional spouts and to have bigger gutters designed for more water volume.

Until we see some photos or know square footage of water run off into what (?) length of gutter and/or dead valley?? is there a pa****t wall? if so, what size is the thru-wall scupper? Its pure speculation to determine a solution to the problem. Not enough data.

Simply calculating the slope and square footage to determine gutter dimensions may not be the solution. Hard to tell all we have to go on is a vague description of the existing conditions. Is the linai adjoining wall lower or higher than the main house? If it's higher what wall flashing was used? If it's low, again, what flashing was used? Is there a saddle/cricket built into the structure or was tapered insulation used? Does it split the water run off 50/50 to each side of the house? Maybe it needs to be sloped to each side of the house. Hard to determine. Need more data.

Roofing is my area of expertise, not saying I know it all, but much much more than most. Truly want to help the guy and I would be a fool to think if other roofers have looked at it and some have refused to even help, that an answer could be so simply written out by reading the vague description provided?

If the guy truly wants a solid solution. That is economical perhaps even something he could do himself. Than we need more data.

Maybe the water could be diverted to another gutter? Maybe an internal drain could be installed to relieve the pressure off the final gutter?
Large volume of water running off funneling into a bottle neck peripheral drainage system is not good during winter months. This could be another problem that has not reared its ugly head yet. Is this located in a snow load area? Hard to tell, we don't have enough data.
What is the collateral weight load for your region of the country? Is point loading a concern? Not enough data. Where is all the water run off going to go if the primary drain is frozen?
What kind of roofing is in place on the main house? shingles, metal, tile or is it a flat roof? membrane? Asphalt?

Need more data.

What I'm trying to point out is there are always options and multiple solutions to any given problem. But it all depends on the existing conditions? What are they? We don't know.

Nobody is questioning the need for more data, including pix of the situation. What was at odds was you requesting that the OP take the conversation privately, as if you and only you could have the answer, which is clearly not the case.

As far as knowing the square footage of the area and diversion characteristics, clearly, more water is being diverted to the single gutter/downspout than the system can handle, regardless of whatever crickets, bolsters, parap-et walls, culverts, rocks, gravel, or small children that may be in the area.

Dude, relax. Not trying to take it into a private conversation. My first post was prompted by his request.

Well, since you started this in a public forum for all to read and I cannot just sit here on my hands without a response to your insulting statement ( as if you and only you could have the answer, which is clearly not the case. ) Not sure how to take that. But, Okay whatever you say A. Spruce
I will not take offense.
Obviously your high post count says you certainly want to get your $0.02 input.

Since we have already hijacked the thread and going way off topic. I think it is irresponsible of you to mention increased gutter size or making a recommendation of any sort with out knowing more about the existing conditions. Someone with a high post count as yourself will be given more weight by nature. You do not know this OP. He/she does not know you or your experiences. Will they return to read follow up postings or will they simply read your initial response and run with it. You should know better.

You do not me or I you. Let our responses to a posed question be the answer and let the OP decide what path they choose to follow.

OP asked for email. I'm not going to post my email address on a public forum and I was trying to catch them before they posted theirs.

I've read a lot of your posts in the past and lurked this forum for quite some time prior to registering an account. I held you in high regard A. Spruce. Today you disappoint me. I forgive your poor judgement and assumption on me. I hope a confrontation will be avoided in the future.

llmotoll and spruce,

May I suggest a cool off period, so this little scrimmage doesn't explode into something it's not.

llmotoll,
While nobody's disputing your roofing knowledge and experience, it was your suggestion to go to private emailing that started the whole thing. Maybe you didn't know, but this forum aims to help those who ask the questions and those who read the answers, but with no warranties. A simple apology will enable all of us to move on.

Many times folks make suggestions here based on limited or incomplete information. Suggestions here are not written in stone, and in fact some could be misleading. I know for fact that many posters are not solely relying on answer given here, and seek more answers in other sites. It's up to the posters to investigate answers before choosing course of action, it's their time and money.

And as far as spruce is concerned, llmotoll, he is an ocean of construction knowledge, and not only by his number of posts (which only means that he has been posting longer...:cool:). Trust me, he only got ticked off by your suggestion to go private...that's all.

Yup! I must also say that it was not my intent to flame anyone, merely trying to point out that conjecture and use of fancy words tend to cloud an issue more than help resolve it.

The info I provided was in response to the data received. I've got a pretty darned good guess as to the problem and the rectification of it just from what little the OP shared. Unfortunately, the cure can be a simple as stated, or preferably and much more expensively, the roof can be reworked NOT to create the problem (and potential suspected hidden problems ) to begin with.

A side note, but related issue, that this topic brings up is the intentional creation of problems due to poor planning, poor design, and poor implementation on the part of the designers and builders, not only of the OP's project, but across the nation, in every suburb. Designers design what is "pretty", with little regard to functionality, resulting in roof configurations that are literal designed leaks. In my 30+ years in this industry I've come across countless instances where roofs failed to keep water out because they trapped water rather than shedding it. Homes are NOT waterproof, they are water resistant, they are designed to shed water, but if that water can't be shed, it will be absorbed by, aka leak into, the house.
