In Oregon, roofing advice is everywhere, from your neighbor’s “guy who knows roofs” to Facebook groups full of conflicting tips. The problem? Much of it is outdated, misinformed, or flat-out wrong. Let’s break down the most common myths and give you real facts from trusted industry leaders.

Myth 1: Metal roofs are noisy in the rain

The Truth: Modern metal roofing is installed over solid sheathing and insulation, making it no louder than an asphalt shingle roof. In some cases, it’s quieter.

Myth 2: You can just layer new shingles over old ones

The Truth: While it may save money up front, it traps heat, hides damage, and adds unnecessary weight to your roof. Many warranties won’t cover layered shingles.

Myth 3: Roof maintenance isn’t necessary until there’s a leak

The Truth: Leaks are often the last stage of a roofing problem. Regular inspections can catch loose flashing, small cracks, or moss growth before they become costly repairs.

Myth 4: A new roof will last its full “rated” lifespan without care

The Truth: Ratings are based on ideal conditions. In Oregon, heavy rain, moss, and temperature swings can shorten that lifespan if you don’t maintain your roof.

Myth 5: All roofing materials work equally well in Oregon

Myth 6: Metal roofs attract lightning

The Truth: Metal roofs do not increase the risk of lightning strikes. In fact, they’re safer than many other materials because they’re non-combustible.

Myth 7: Roof color doesn’t affect your home’s temperature

The Truth: Light-colored and reflective shingles can keep attics cooler in summer. In heat waves, this can lower cooling costs.

Myth 8: Moss makes your roof look “rustic” and harmless

The Truth: Moss holds moisture, lifts shingles, and rots roof decking. It’s a top cause of early roof replacement in the PNW.
