About Grizzly Rain Gutters

Built on Craftsmanship and Honest Pricing

Grizzly Gutters LLC is a licensed Arizona contractor (AZ ROC #357629), owner-operated by Zach Stephenson. We specialize in copper and aluminum seamless rain gutters, gutter guards, gutter repair, gutter cleaning, downspout installation, and permanent year-round holiday lighting. Our copper seamless gutter work is a true specialty — hand-formed copper systems that bring a century-quality, patina aesthetic to heritage homes, custom estates, and historic properties throughout Arizona. We serve the entire state: Phoenix Valley homeowners dealing with monsoon season and relentless summer heat, Flagstaff properties facing snow loads and freeze-thaw cycles, and Tucson homes managing their own distinct monsoon and desert climate patterns. Locally owned, no franchises, no middlemen — just Zach and a crew that shows up on time and stands behind every installation.

Grizzly Gutters LLC serves all of Arizona with a particular focus on three regions. Phoenix Valley is one of the fastest-growing metros in the US — both new construction and replacement/upgrade work on undersized builder-grade systems is constant. Flagstaff is an underserved mountain market where most valley contractors do not operate; copper gutters fit naturally with Flagstaff's historic craftsman and mountain-style architecture, and freeze-thaw-rated systems are a genuine specialty. Tucson's Barrio Viejo, Sam Hughes, and historic districts have heritage homes — Spanish Colonial Revival, Mission Revival, and Territorial style — where copper gutters are architecturally authentic and a genuine differentiator. Across all three markets, Grizzly's copper specialty and AZ ROC license set us apart from unlicensed competitors and commodity aluminum installers.

Arizona presents three distinct gutter climates. Phoenix Valley (Maricopa County): intense monsoon bursts from July through September can drop over an inch in under an hour, combined with 160°F rooftop temperatures that stress sealants and coatings year-round. Dust storms pack debris into every joint and downspout. Flagstaff Area (Coconino County, elevation ~7,000 ft): heavy winter snowfall, ice dam formation, and aggressive freeze-thaw cycles that expand and contract every joint — a fundamentally different failure mode from the valley. Flagstaff also receives substantial summer monsoon rainfall. Tucson Area (Pima County): monsoon season brings intense concentrated rainfall similar to Phoenix, with its own local storm patterns. Tucson homes often have historic or adobe-influenced architecture where proper drainage is critical to protecting adobe and plaster exteriors. Proper gutter sizing, materials, and installation differ meaningfully across these three zones.
