Mercer Island Roof Measurement: Know Your Numbers Before the Bids

On an island where re-roofing bids can swing five figures apart, Mercer Island homeowners should walk in with their own measurement. It's free and takes a minute: trace your roof on satellite here — area, squares, gutters, and 2026 cost ranges.

Island roofs are their own category

Mercer Island mixes eras like nowhere else on the Eastside: genuine mid-century moderns with low-slope and flat sections, 70s–80s daylight ramblers stepping down toward the water, and substantial new customs with complex hip rooflines. Two measurement notes that matter here:

• Low-slope sections (common on MCM homes) measure near their footprint — but they're priced differently, since membranes replace shingles below ~2/12. Trace them as separate sections so the report itemizes them. (Pitch rules explained →)
• Privacy trees: island lots are famously wooded. Trace visible edges and use the report's AI cross-check to confirm.

Worth measuring before any conversation

• Per-section areas — shingle planes vs. low-slope planes
• Hips/ridges and valleys in linear feet
• Gutter runs (stepped daylight-rambler rooflines carry more than you'd think)
• Cost ranges sized to your actual area, entry through premium and metal

FAQ

Can the tool handle my flat roof section?

Yes — trace it as its own section with the flat/low pitch selected; it lists separately so membrane pricing can be applied to it.

Are Mercer Island roofs more expensive?

Often, yes: larger customs, mixed systems (shingle + membrane), and premium material choices. Size is still the biggest lever — measure first.

Will you match the satellite measurement on-site?

That's the point: the free number and our physical measure should reconcile within a few percent before anything is ordered.
