FAQs
Do all gutters need downspouts?
Yes, although in some very rare cases no end caps may be used to let water run off, or rain chains may also be used.
What size downspout do I need?
That question needs to be based on the roof area, the amount of rain the property receives and the pitch of the roof. Normally, 5" gutters call for 2"x3" or 3" downspouts while 6" gutters will have 4" or 3"x4" downspouts. For aesthetics, if the water runoff allows, 6" gutters may receive 3" or 2x3" downspouts. It is standard, although not mandatory to have square downspouts with k-style or box gutters and round downspouts with half-round gutters or brownstone gutters.
Can I get custom sizes and colors?
Yes, we can make longer downspouts, up to 19'6" with special colors and materials along with gutters and all accessories needed. It is not uncommon for us to manufacture 3x3, 4x4, 4x5, 4x6, 5x5, 6x6, 6", 7" and 8" round downspouts.
However, corrugated downspouts are roll formed. That means an specific machine is needed to run such profiles. Therefore we can only offer 3"x4" and 4" corrugated downspouts, but may be able to
acquire other size downspouts from other manufacturers.
How do downspout lengths fit together?
The ends of some downspouts are crimped to accept another length. This is not always perfect, or always the case, for example plain square downspouts are not crimped and need to be notched on site. For such situations, or when a length needs to be cut we offer tools such as crimpers and snips.
What about leaves in my downspouts?
To fix the problem, you may purchase our gutter screen, that will protect the gutters from leaves. Strainers, will protect the pipes from leaves, while our own gutter downspout cleanouts allow for the downspouts to be cleaned when strainers are not present, however, even if present, some debris may still passed through.
Can I fit different size downspouts together?
Absolutely! We offer funnels and square to round downspout adapters.
Steel vs. Galvalume Plus vs. Aluminum vs. Copper vs. Zinc, so many choices!
