Great system, and a great team. Victor, Daniel, and Patrick were very professional and thorough during the installation. The roof looks and performs great.

Metal Roofing in Marion County, Oregon
Marion County is capital country — Salem and Keizer's established neighborhoods, Silverton and Mount Angel at the foothills, Woodburn and the farm towns of the French Prairie. It's classic Willamette Valley roofing territory: long wet winters, moss on every north-facing composition roof, and homeowners tired of re-roofing every twenty years. An Interlock aluminum roof ends that cycle — installed once, under the Guardian Lifetime Limited Material Warranty, which transfers once if you sell, with the second owner covered to 50 years from substantial completion.

THE NUMBERS THIS ROOF HAS TO SURVIVE
Ten-year averages for Marion County: about 52 inches of rain and 11 inches of snow a year, a mean temperature near 54°F, gusts recorded to 69 mph, and roughly 39 freeze-thaw days. The last two decide how long a roof covering lasts here, and they are the two figures almost nobody quotes a homeowner.
RAINFALL — 52 INCHES A YEAR, AND THE MOSS THAT COMES WITH IT
The valley's wet season runs long enough to keep a north slope damp most of the year, and moss roots between asphalt granules, holds water against the mat, and lifts each tab as it grows. That is the failure mode in Marion County — not a storm, but fifteen quiet years and a wash-and-treat bill every few seasons. Smooth interlocked aluminum gives moss nothing to grip, sheds no granules, and needs no treatment schedule.
FREEZE-THAW — 39 DAYS A YEAR
Freezing on its own does not damage a roof. Freezing and thawing does, and Marion County crosses that line roughly 39 times a year. Every cycle drives water into a seam, expands it, and reopens it slightly wider. Interlock carries no sealant beads doing the waterproofing and no exposed gaskets to age, so there is nothing for that cycle to work on.
GUSTS TO 69 MPH
Wind damage is a covering problem, not a structural one — which is why it shows up as missing shingles rather than a failed roof. Asphalt depends on an adhesive strip holding a free tab edge down, and once one lifts its neighbors are exposed in turn. Every Interlock panel locks to its neighbors on all four sides with concealed fasteners, so there is no free edge for a gust to get under and no fastener head sitting out in the weather. Wind resistance is warranted to 120 mph installed to manufacturer specification.

Crew was amazing, we had one main house roof and two porch roofs that needed to be done fast and before the rain and they handled it well! Our metal roof got finished in two days and they came back out again to clean up on the third day and wrap up everything. We highly recommend them and their service as everything turned out great! Edit: I forgot to mention, we worked with a few different people but I believe it was Patrick and his crew whom helped us
