Our Story

Built for Arizona Roofs, Not a Catalog

Flow-Rite Seamless LLC has been installing gutters across the Phoenix Valley since 2008. We're veteran-owned and we've stayed deliberately small, small enough that the person who quotes your job is the person who shows up to do it.

The gutters we install are formed on site. A coil of aluminum goes into the machine at your curb and comes out as one continuous length cut to your roofline, so a forty-foot run has no joints in it at all. Sectional gutter from a big-box store gets seamed every ten feet, and in Phoenix every one of those seams is a future leak. The sealant bakes through a 115° summer, then the first monsoon finds the gap.

We run 6-inch K-style, half-round, and copper, in 28 factory colors, for both homes and commercial buildings. If your existing gutters were installed badly by someone else, we'll tell you what actually went wrong before we quote a fix.

Licensed, Bonded and Insured

Arizona ROC #300914. You can verify the license yourself at roc.az.gov before anyone sets foot on your property, and you should, with any contractor.

Sectional Gutter vs. Seamless Formed On Site

Sectional, Store-Bought

  • A seam every ten feet, each one sealed with caulk that dries out in Arizona heat.
  • Joints catch dust, gravel and debris, then dam up and overflow in a downpour.
  • Stock lengths and stock colors, close to your trim, rarely matched to it.
  • Often installed by whoever the contractor subbed it to that week.
How We Do It

Seamless, Formed at Your Curb

  • One unbroken run from corner to corner, no joints, so nothing to leak.
  • Cut on site to your roofline, so the fit is exact rather than close enough.
  • 28 factory colors, matched to your fascia and trim before we form anything.
  • Installed by our own crew, under ROC #300914, not handed to a sub.
How We Work

Four Things We Don't Compromise On

None of this is complicated. It's just the part most contractors skip when they're busy.

We Show Up When We Said

We return calls the same day and arrive in the window we gave you. If something changes we call you before you notice, not after.

On Time, Or You Hear From Us

The Owner Writes the Quote

You get a written price from the person doing the work, on the spot. No commissioned salesperson, no follow-up "manager approval" call, no surprise line items later.

Written, Not Verbal

Formed at Your Curb

The machine comes to your house and the gutter is made there, in one piece, in the color you picked. Most single-story installs are done inside a couple of hours.

Zero Seams

We Clean Up After Ourselves

Screws, offcuts, packaging: it all leaves with us. Your driveway and yard look the way they did before we pulled up.

Nothing Left Behind

Our Own Crew
No Subcontractors

The people on your roof work for Flow-Rite. That's how the work stays consistent from one job to the next.

On the Job

Arizona Roofs Have Their Own Rules

Tile, stucco fascia and parapet walls all need to be handled differently than the pitched shingle roofs most gutter guides are written for. Getting this wrong is what cracks tile and pulls anchors out of fascia.

Tile and Stucco, Handled Properly

Spanish and S-tile can't simply be walked on, and desert stucco crumbles if anchors go in wrong. We work around both instead of hoping for the best.

Sized and Sloped for Monsoon

Valley storms drop a lot of water in a short window. We size the gutter and the downspouts to the roof area feeding them, and set the slope so it actually drains.

Awkward Work Included

Cutting metal over a shed, moving a cable line that's in the way, fixing what a previous contractor left behind. The things other companies decline are usually the reason people call us.

The People You'll Deal With

A Small Team, On Purpose

You'll deal with the same small team from your first call through the final walkthrough.

Highly recommend Flow-Rite Gutters. They were responsive from the first call and gave a reasonable price for the work. I'd had a failed gutter system installed by a previous contractor, and Flow-Rite correctly diagnosed the problem and walked me through exactly how they'd fix it before starting. The installation crew showed up on time, worked efficiently, and were professional throughout. When they finished, they left the site completely clean: no debris, no mess.

After another company told me they didn't cover Tempe, I found Flow-Rite Gutters in Phoenix. My call was returned within an hour by Nikki, who answered my questions and listened very carefully to me. Justin was on time, and after explaining exactly what he would do he wrote up a bid on the spot. They set up this very professional looking machine in the street to shape one of the thirty plus feet sections of gutter. When they finished, I was completely satisfied. The color matched perfectly. It rained fairly hard a week later. The wider gutters, with an additional downspout, worked perfectly.

Flow-Rite was very professional from the first phone call. I liked that Justin provided the quote and was also involved in doing the work and installation. I preferred this to other companies that sent out a salesperson with less knowledge. The installation of the seamless gutters was painless and only took around 2 hours. Nikki was a pleasure to work with regarding scheduling and payment. I would use Flow-Rite again and will recommend them to friends, family and neighbors.

Flow-Rite did an exceptional job coming up with a plan to install a new gutter in the front of my house which looks nice, and they were able to make repairs on an older existing one. Nikki answered all of my questions quickly and Justin and his team came out and did a perfect job. I couldn't be happier. Highly recommend.

We've used the services of Flow-Rite on three separate occasions over the years and have been pleased each time. They do good work, show up when they say they will, and clean everything up when done. We are happy to recommend them to friends and clients, and recommend them to you as well.

Great work by the Flow-Rite team. Gutters look great, color matches perfectly and fair pricing. These guys were willing to cut metal on top of our shed as well as relocate cable wires that other companies were unwilling or unable to do, which greatly helped us out!
