How to choose a gutter contractor in Arizona.

Start here: verify the licence. It takes 60 seconds.

Arizona requires a contractor licence for any construction work of $1,000 or more, including labour and materials. A typical gutter installation in the Phoenix area comfortably exceeds that, which means essentially every real job requires a licensed contractor.

Gutters sit under the sheet metal classifications:

Look the contractor up at the Arizona Registrar of Contractors. Check three things, not one:

1. The licence exists and the name matches the company bidding your job.
2. The status is active — not expired, suspended or revoked.
3. The classification covers your work. A residential-only classification does not authorise commercial work. Most people check the number and never check this.

For the record, ours is AZ ROC #365076, CR-45. Look it up. You should be looking up everyone who bids your house.

The 12 questions worth asking every bidder

Ask all of them of every company, including us. The answers are more revealing than the price.

1. What is your ROC number and classification? A hesitation here tells you everything.
2. Are you insured, and can I see a certificate? Current, not expired.
3. Who actually does the work? Your employees, or subcontractors you have not met?
4. What gauge aluminium do you install? Thinner material dents and oil-cans more easily.
5. How far apart are the hangers? Wider spacing is faster and cheaper, and it is why gutters sag.
6. Hand-cut corners or snap-in box miters? A visible difference on any elevation you look at.
7. Five inch or six inch, and why for my roof? The answer should reference your roof area and pitch, not a default.
8. What size downspouts, and how many? Capacity is a system, not just the trough.
9. Where does the water go after the downspout? The question most quotes ignore entirely.
10. Have you checked the fascia? Gutters hang off it. If it is soft, that work comes first.
11. What exactly does the warranty cover, and for how long? Material and workmanship separately.
12. Is the warranty transferable if I sell? Worth knowing before, not at closing.

Why is one quote so much cheaper?

Almost always something specific, not generosity. When quotes diverge significantly, the gap usually traces to one of these:

• Thinner aluminium — cheaper per foot, less rigid over long runs
• Wider hanger spacing — fewer parts, faster install, more sag later
• Snap-in box miters instead of hand-cut and sealed corners
• Cheaper hardware — straps and fasteners are where cost gets quietly cut, and they fail first
• Subcontracted labour — the crew on your roof is not the company you vetted
• Sectional rather than seamless — pre-cut lengths joined on the wall, with a joint at every junction
• No drainage — the water gets collected and then dumped at your foundation

None of this means the cheaper company is dishonest. It means you are comparing two different products. Find out which one you are buying.

Red flags that should end the conversation

• No licence number, or reluctance to give one
• Cash-only, or a large deposit demanded before anything is scheduled
• No written contract — Arizona requires one over $1,000
• High-pressure "today only" pricing. Gutters are not a limited-time offer
• Refusal to put the warranty in writing
• A quote with no scope — just a number and a signature line
• Door-knocking immediately after a storm, especially from out-of-state plates
• No physical business address or verifiable local presence

What Arizona law entitles you to

Two protections worth knowing, because a contractor who does not mention them is either unaware of them or hoping you are.

A written contract

Under A.R.S. §32-1158, residential work over $1,000 requires a written contract containing the contractor’s name, business address, licence number, scope of work, total price, estimated completion date, and a notice of cancellation rights.

Three days to change your mind

If you signed at your home, the FTC Cooling-Off Rule generally gives you until midnight of the third business day to cancel for a full refund, on any sale of $25 or more made at the buyer’s residence. The contractor must tell you about it and give you a cancellation form. Most in-home contractor sales are covered.

The Arizona-specific things a good contractor will raise

These are the tells that someone actually works in this climate rather than applying a national playbook:

• They ask about your roof type — tile, shingle or low-slope changes the attachment and the approach
• They mention monsoon intensity rather than annual rainfall. Phoenix gets about eight inches a year, nearly all of it in short bursts, and sizing follows the burst
• They look at where the water goes, not just where it is caught
• They are honest about gutter guards and dust — micro-mesh handles pods and litter well, but fine dust can film the surface and needs occasional rinsing
• They check the fascia before quoting
• They do not recommend vinyl, which degrades noticeably faster under this much UV and heat
