Never
Re-Roof
Again.® Lifetime Interlock® metal roofing, installed across Oregon.
One decision removes roofing from your life for good — no moss creeping across the north slope, no exposed seams for wind-driven rain to find, no repeat tear-off every 20 years. Guaranteed in writing: The Guardian Warranty, lifetime coverage — and if you sell, the next owner is covered to 50 years.
What changes when an Interlock metal roof goes on your Oregon home.
Relentless valley rain stops mattering — and the moss goes with it
West of the Cascades, asphalt holds moisture and feeds moss. Smooth interlocked aluminum sheds both — no cleaning cycle, no zinc strips, no soft spots.
Salt air corrodes steel — aluminum cannot rust
From Astoria to Florence, salt spray disqualifies steel and strips asphalt. Aluminum has no iron to oxidize — coastal installs carry the same warranty as inland ones.
Recycled aluminum
The last tear-off your house will ever see — nothing to the landfill every 15 years.
Wind-rated where the Gorge funnels it
ICC-ES ESR-1790: wind uplift tested to 177.5 psf. Panels lock on all four edges — no free tabs for Hood River or The Dalles gusts to work loose.
Class A fire rating — non-combustible aluminum overhead
Aluminum doesn't ignite. Class A–rated assemblies are available — the home-hardening answer for Oregon's fire seasons.
How long does a metal roof last? We've installed them here for 29 years.
The proof is photographed, not promised.
Metal roof cost vs. asphalt, cedar & slate in Oregon: the math nobody shows you.
