Wasco County, OR

Metal Roofing in Wasco County, Oregon

Wasco County is Oregon's other climate: The Dalles sees a fraction of Portland's rain but nearly 50 freeze-thaw cycles a year, high-desert sun that cooks asphalt, and the east-Gorge wind that funnels past Rowena and Mosier. Aluminum is built for all three — the Alunar coating is warranted 30 years against UV, the metal doesn't care about freeze-thaw, and the interlocked panels are wind-rated far beyond anything the Gorge delivers. CRRC-rated colors reflect summer heat, too.

THE NUMBERS THIS ROOF HAS TO SURVIVE

Ten-year averages for Wasco County: about 18 inches of rain and 22 inches of snow a year, a mean temperature near 54°F, gusts recorded to 52 mph, and roughly 48 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 — 18 INCHES, AND WHY THIS IS NOT THE WILLAMETTE VALLEY

Wasco County sits in the Cascade rain shadow and takes about 18 inches of rain a year against Tillamook's 81 on the coast. The moss problem that defines roofing west of the mountains is largely not your problem. Anyone selling you a roof here on a moss argument is reading from the valley script.

WHAT REPLACES IT — THERMAL CYCLING, 48 FREEZE-THAW DAYS

Freezing on its own does not damage a roof. Freezing and thawing does, and Wasco County crosses that line roughly 48 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. On the dry side that cycle is paired with hard summer sun, so a covering is expanding and contracting through a wider annual range than anything in Portland sees. Interlock panels are engineered to move — the interlock accommodates expansion rather than fighting it, and no part of the waterproofing depends on a sealant that hardens with UV.

SNOWFALL — 22 INCHES, AND WHAT THE COVERING WEIGHS

Snow load is a structural question answered by your framing, not your roof covering. The Interlock covering adds about 0.7 lb per square foot — less than a second layer of asphalt would.

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

★★★★★

Maybe the best decision we’ve ever made. Looks incredible ! The roofers (Victor and Daniel) were pleasant and did an amazing job. They were kind and courteous and very tidy. Totally worth the expense. I would recommend them to anyone.

★★★★

I had a very good experience with Interlock. From the initial presentation to the installation, I was very impressed with the knowledge and thorough nature of each step. The finished product looks beautiful too! To know that I have a lifetime warranty on my 'forever home' is incredibly peace giving. If a company offers you a lifetime warranty on everything but the color (that warranty expires after 30 years), you know they will do all they can to make the finished product perfect! My ONLY reason for not giving 5 stars was that during the estimate, we were told we'd need to replace plywood due to mold. When it came time to actually install the plywood, they needed to double the amount required which increased our bid by over $2K. Obviously I wish the original estimate had been more accurate. That said, our attic now has the correct amount of ventilation, fresh plywood with no mold, protected skylights and solar tubes and a beautiful finished product. I'm very happy! If I could give 4.5 stars, I would!
