Too few downspouts cause overflow. Too many look messy. We calculate the right count and placement for your roof.
In Minneapolis and St. Paul, spring melt and summer storms move a lot of water fast. Downspouts that empty at the foundation turn a good gutter job into a wet basement problem.
Proper spacing for your roof size
Extensions to protect foundation
Repairs for disconnected or crushed downspouts
Options for buried drainage
Drainage that works
Gutters fail at the outlet as often as on the eave.
Beautiful seamless runs still flood a basement if downspouts are too few,
too small, or empty water at the foundation wall.
How we size the system
Rule of thumb is one downspout for every 30–40 feet of gutter run, then we adjust
for roof area, pitch, and how hard Twin Cities storms hit your side of the house.
Undersized 2×3 downspouts on a large roof plane get upgraded to 3×4 so water can
leave as fast as it arrives.
Outlet placement follows the low points of a correctly pitched run — not wherever
the old holes happened to be. That alone fixes a surprising number of "mystery overflows."
Where the water should go
Splash blocks or extensions that carry water several feet from the foundation
Buried drain lines when grade or landscaping will not allow surface runoff
Elbows that clear stairs, walkways, and AC pads without creating ice sheets
Disconnects from cracked clay tiles or clogged underground that back up into the gutter
Repairs, replacements, and new installs
Downspout work is included with every new
gutter installation
and
replacement.
Standalone visits cover reattaching sections after ice, replacing crushed elbows,
adding outlets to overloaded runs, and extending discharge away from basements that
already show moisture.
If underground drains are collapsed or full of roots, we tell you before promising a
surface fix that will not hold. The goal is simple: roof water leaves the house and
stays away from the foundation through spring melt and summer storms —
with the same 5-year workmanship coverage as the rest of the system.
Part of the system
Downspouts are not an afterthought.
Every new gutter install and replacement includes downspouts sized to the roof. Standalone visits fix ice damage, add outlets to overloaded runs, and extend discharge when landscaping changed the grade.
If an underground line is collapsed, we will not pretend a longer elbow solves it — you get a clear recommendation and a price for the work that actually moves water away.
Every project below is ours — address area, actual price and time on site.
These are representative jobs from our 500+ projects across the Twin Cities.
A good rule of thumb is one downspout for every 30–40 feet of gutter run. We adjust based on your roof size and slope.
Can you redirect downspouts away from the foundation?
Yes. Extensions, buried drain lines, and splash blocks are all options we can install.
Do you repair downspouts?
Yes. We reattach, reroute, or replace downspouts and elbows.
What size downspouts do you use?
Standard 2x3 or oversized 3x4 downspouts, depending on the roof area and volume of water.
Are downspouts included in gutter installation?
Yes. Our installation quote includes gutters and downspouts as a complete system.
How do downspouts prevent basement flooding?
By carrying roof water away from the foundation. Without proper drainage, water pools and can seep into the basement.
