Gutter Size


I just got into a new shop and I am in need of some new gutters. The building length I am concerned with is 50' long and a pitch of about 5/12. From the gutter to the peak of the roof is about 24'. Would regular residental gutters, 4" i think, be enough to handle a heavy rain or do I need something more industarial in size? I can provide pics of the building.

Re: Gutter Size


I would get a gutter guy to install the commercial 6" gutters and the bigger 3x4 downspouts. Maybe even bigger. A good gutter man will know what it needs.

This is one of my suppliers, they have all the tables you need to determine gutter sizing. I'd C&P the necessary info for you but I have to hit the road in 2 minutes. http://chrisind.com/architect.htm

Re: Gutter Size


I see a few guys around here "upsell" residential people to 3x4 downspouts but only install a 2x3 outlet....

LOL I see that alot also. Even worse some guys just punch an X of the gutter and hang the downspout from the flaps. Honestly I tell my customers 2x3 or 3x4 is the same cost. We are going to do what's right for their home.

Or when we are bidding a repair and part of the repair is to install a larger downspout, and they can't understand why I want to change the outlet size. It's like a chain only being as strong as the weakest link, well a gutter is only as large as the smallest hole.

Re: Gutter Size


Grumpy is right. The cost difference between 2x3 and 3x4, and 3x4 and 4x5 is minimal. Use a 6" gutter (4" is never a good idea. It is rarely large enough and more expensive than 5") and 3x4 downspout. IF there is only one outlet, definatley use a 4x5.
