Metal vs. Asphalt Shingle Roofing — Which Is Worth It for a Tacoma Home?

Both materials are real, common options in Tacoma — the right one depends on how you weigh upfront cost against lifespan and wind performance.

Cost comparison

Based on a real Tacoma-market contractor’s material-specific pricing: asphalt/architectural shingle runs roughly $420-$1,040 per roofing square installed, while standing-seam metal runs roughly $1,040-$2,600 per square — generally two to three times the upfront cost of shingle for the same roof size. That gap is the central tradeoff in this decision: metal costs significantly more to install, and the question is what you get for the difference.

Lifespan

Asphalt shingle carries a manufacturer rating of 20-30 years, though Pacific Northwest conditions — sustained moisture, moss, and wind exposure — routinely shorten realized lifespan below that rating across the region. Standing-seam metal roofing typically lasts substantially longer than asphalt shingle, often decades beyond a shingle roof’s realistic service life, which is part of what offsets its higher upfront cost over the long run.

Wind performance

This is where the two materials diverge most for a property in this specific location. Tacoma sits directly on open Puget Sound water at Commencement Bay and near the Tacoma Narrows — genuine, recurring wind exposure, especially during windstorm season (roughly November through February). Standing-seam metal’s continuous, mechanically-fastened panel system offers meaningfully stronger wind-uplift resistance than individual shingle tabs, which can lift and tear in high wind even when properly installed. For a property with direct, unobstructed wind exposure, that’s a real practical advantage, not just a marketing claim.

Maintenance and moss resistance

Asphalt shingle’s textured surface gives moss and algae more to grip onto than metal’s smooth panel surface, which sheds debris and dries faster. Metal roofing generally needs less moss-specific maintenance over its life than shingle does in this climate, though neither material is fully immune to it.

Appearance and historic-district fit

Asphalt/composition shingle is the material most associated with Tacoma’s historic housing stock and is explicitly named as the typical historic material under Landmarks Preservation Commission guidance for North Slope and Stadium-Seminary. Standing-seam metal is acceptable on simple roof structures within those districts, but the fit depends on the specific home’s style and roofline complexity — worth discussing before committing to either material on a historic property.

How to actually decide

If minimizing upfront cost matters most and the property doesn’t have unusual wind exposure, shingle remains a sound, proven choice at roughly a third to half the cost of metal. If you’re planning to stay in the home long-term, want to minimize wind-related repairs on an exposed property, or want to reduce moss maintenance over time, metal’s higher upfront cost is a real, defensible tradeoff rather than an upsell.

Bottom line

Shingle costs less upfront and remains the standard choice; metal costs more but lasts longer and handles wind exposure better. Call (253) 201-1336 and we’ll price both for your specific roof so you can compare the real numbers side by side.
