How long does a metal roof last?

A metal roof typically lasts about 70 years, and up to 100 years when it's well maintained. The paint finish carries the paint manufacturer's warranty.

Is a metal roof noisy in the rain?

Installed over solid decking and underlayment, as residential metal roofs typically are, a metal roof is generally no louder than other roofing types.

Can you install metal over my existing roof?

No. We always tear off the old roof first, so we can check the deck and install the new roof on a clean, solid base.

How long does it take to switch from shingles to metal?

Tear-off takes one to two days at most, and the whole project runs about 2 to 12 days depending on the size and complexity of the roof.

How much does a metal roof cost?

Cost depends on roof size, complexity, panel profile, and material. Metal costs more upfront than asphalt but typically lasts much longer. We provide free, detailed estimates within 24–48 hours.

Do you do commercial roofing?

Yes. We install metal roofing on both residential and commercial projects.

Standing seam metal roof on a two-story home in Lake Oswego, OR

Liberty Sheet Metals has installed metal roofs across Oregon and Washington for more than 30 years. We don't split our attention between asphalt shingles, tile, and metal. Metal is all we do, and that focus shows up in the details: clean seams, straight lines, and flashing that keeps Northwest rain where it belongs.

Building a custom home, replacing a worn-out composition roof, or roofing a commercial building? We'll help you choose the panel, material, and color, then fabricate and install it with the precision a long-term roof demands. On a replacement, we always tear off the old roof first; we never install metal over it.

Steel vs. Aluminum

We install 24-gauge panels in both steel and aluminum. Steel is the most common choice for residential roofs: strong, cost-effective, and available in a wide range of colors. Aluminum doesn't rust, which makes it a good fit near the coast or in high-moisture environments. We'll recommend the right material for your building and budget.

Aluminum: won't rust
Aluminum suits coastal homes

Built to shed heavy rain, resist moss buildup better than composition shingles, and handle wind, snow, and temperature swings. A metal roof typically lasts about 70 years, and up to 100 when it's well maintained. The paint finish is covered by the paint manufacturer's warranty.
