Gutter installation
New gutter systems planned around your roofline layout, drainage needs, water flow and downspout placement – installed by Johnson Exteriors, a family-owned exterior contractor based in Saint Michael.

Planned, not just hung
Every home drains differently. Roof size, roof pitch, valleys, run lengths, landscaping, walkways and foundation areas all change where water goes – and where it needs to go. A new installation is the best chance to get that right.
Before installation, Johnson Exteriors looks at how each section of your roof sheds water, then plans gutter size, material, layout and downspout locations so runoff is carried away from the home instead of spilling over the edge.
What we plan
These are worked out before installation day, so the finished system fits your roof and the way water moves around your property.
Where gutter runs start and end, how sections connect, and how valleys and inside corners are handled.
5″ or 6″ aluminum for most homes, or copper where appearance and architectural detail are priorities.
Gutters set to move water toward outlets instead of holding it, based on run length and drainage volume.
3″x4″ aluminum downspouts positioned to discharge away from foundations, walkways, patios and entries.
Why it matters
Gutters do more than catch rain. When they work, they keep water off – and away from – the parts of your home that are expensive to repair.
Water that overflows the gutter edge soaks the boards behind it.
Controlled runoff means less staining, splashing and water at openings.
Water discharged away from the house lowers basement moisture risk.
Downspouts placed with intent prevent erosion and icy, puddled paths.
Choose your system
Most installations combine a gutter material with the right downspouts – and, if you want less maintenance, gutter guards.

St. Michael & Minnesota
Gutters in St. Michael handle spring downpours, summer storms, fall leaves and a long season of snow and ice. Snowmelt sends a steady volume of water off the roof, and poor drainage near downspouts can leave icy walkways and entries.
That’s why we plan size, pitch and downspout locations around the heaviest conditions your roof will see – not just an average rain.

It depends on the home and the project scope. A new installation may include 5″ or 6″ aluminum gutters or copper gutters, 3″x4″ aluminum downspouts and, if you want them, gutter guards. We plan the layout, gutter size and downspout locations before any work starts.
We look at how each section of roof drains, how long the gutter runs are, and where water can discharge without landing on foundation areas, walkways, patios or entries. Downspout placement is one of the biggest factors in whether a gutter system actually protects the home.
5″ aluminum gutters are a common choice for homes with a standard roofline and typical drainage needs. 6″ gutters suit higher water flow, larger roof areas or more complex drainage. We recommend a size after looking at your roof design, pitch, water volume and run lengths.
Yes. Gutter guards can be included with a new installation. They work best on gutters that are properly sized and pitched, with well-placed downspouts – which is exactly what a new installation is planned around.
