What's Different About Re-Roofing a Home in Tacoma's North Slope Historic District?

North Slope is one of the largest historic districts in the country, and its roofing rules genuinely differ from the rest of Tacoma once a permit enters the picture. Here’s exactly how.

What North Slope actually is

The North Slope Historic Special Review District covers 950+ contributing properties, listed on the Tacoma Register in 1994 and expanded 1996-1999, then added to both the Washington State and National Registers in 2003. It’s built from three distinct construction booms — 1888-1893, 1902-1915, and 1919-1929 — with roughly 80% of the district’s homes built before 1930, in a genuine architectural mix of Stick Style, Queen Anne, Craftsman, American Foursquare, Tudor Revival, and Mission Revival design. This isn’t a uniform housing stock; it’s several distinct eras of building layered into one neighborhood.

The rule that actually governs your roof

The district doesn’t create a separate permit requirement — the standard Tacoma re-roof rule still applies: a tear-off-and-replace re-roof with standard-weight material and no roofline change is generally permit-exempt anywhere in the city, North Slope included. What changes is what happens once a permit is triggered for another reason (layering over existing roofing, or a roofline change): inside North Slope, that permit brings Landmarks Preservation Commission design review under Tacoma Municipal Code 13.05.047 along with it.

What the design review actually looks at

The Commission’s published guidelines focus on two things: roof pitch and material compatibility with the district’s historic character. Composition shingle is identified as the typical historic material across North Slope’s building stock. Standing-seam metal is called out as acceptable specifically on simple roof structures — meaning the review isn’t a blanket ban on non-shingle materials, but it does weigh how a given material reads on a given roof’s complexity and visibility.

Why this matters more here than elsewhere in Tacoma

Because North Slope’s housing stock skews so heavily pre-1930, re-roofing here more often intersects with two things at once: design-review material questions and the practical reality of century-old roof decking underneath the existing roofing. Pulling old roofing off a home this age frequently reveals deck conditions that weren’t visible from the surface — see our guide on century-home roof-deck problems for what that typically looks like and what it adds to a project.

How this differs from Stadium-Seminary

North Slope and the Stadium-Seminary National Historic District share the same review process (TMC 13.05.047) and the same city, but they’re genuinely different districts with different boundaries and a different architectural character — Stadium-Seminary centers on the bluff above Commencement Bay near the French Chateau-style Stadium High School. Our separate guide covers Stadium-Seminary’s specifics.

Bottom line

A North Slope re-roof follows Tacoma’s standard permit-exempt rule until a permit is triggered — at which point Landmarks Preservation Commission review under TMC 13.05.047 evaluates pitch and material against the district’s pre-1930 character. We handle that review process as part of the job. Call (253) 201-1336 and we’ll walk your specific property through it.
