## Price

$8,700-$34,000 full roof replacement, installed. reconciles Eastside-specific contractor data (Emerald City Construction, $8,700-$17,000 for an asphalt shingle full replacement) against WA-wide contractor-published ranges (Valentine Roofing, $15,600-$34,000 for composite shingle) — both narrower and more defensible than the $16,588-$97,105 span published for Issaquah by aggregator sites, which blends small jobs with large metal and low-slope replacements; see the cost guide for the full breakdown by material.

## What's included

- On-site inspection and a written price before any work starts, broken out by material option
- Full tear-off to the deck — the only way to find and fix moss-driven deck damage hiding under old roofing, more common here given Issaquah's 60-65 inches of annual rainfall
- Deck inspection and replacement of any rotten or delaminated sheathing, priced as its own line
- High-wind-rated synthetic underlayment across the field, ice-and-water membrane at eaves and valleys
- New flashing, drip edge, and step/counter flashing at every penetration, chimney, and wall tie-in — never reused off the old roof
- Material and fastening matched to King County's wind and snow-load code, with Class A fire-rated assemblies used where a property sits in wildland-urban interface terrain near Cougar, Squak, or Tiger Mountain
- A MyBuildingPermit.com permit pulled when the job requires one — not every like-for-like composition reroof does, and we tell you honestly which situation applies before we quote the job
- Full site cleanup, magnet sweep for dropped fasteners, and haul-away of the old roofing

## Process

01. **Free on-site inspection** - We walk the roof, check the deck from the attic side where we can, count penetrations and valleys, and note how much moss or algae has already gotten under the shingle tabs or shakes. You get a written price before we leave.
02. **Permit check and material order** - We confirm whether your reroof needs a permit through MyBuildingPermit.com — a single-family composition-over-composition reroof of two layers or fewer typically doesn't — and order the exact material, weight, and color your roof needs.
03. **Tear-off and install** - Deck repaired where moss or age has damaged it, underlayment and flashing installed to spec, then the new roof installed to the manufacturer's wind and fastening requirements for this foothill climate.
04. **Inspection and walkthrough** - Final inspection, magnet sweep for fasteners, gutters and landscaping checked for debris, and we walk the finished roof with you before we leave.

## When it's needed

- Multiple roof leaks, or a leak that keeps returning after repair
- Widespread moss or algae coverage with shingles lifting or shakes cupping underneath it
- Roof is at or past its material's expected service life — 25-30 years rated for architectural shingle, but realistic performance in this climate without active moss management often runs closer to 18-22 years
- Visible sagging, soft spots, or deck damage found during an inspection
- Storm or wind damage covering more than a small, isolated area
- Preparing to sell and a pre-listing inspection flagged the roof

## FAQ

**How long does a roof replacement take in Issaquah?**

Most single-family homes take two to four days once material is on-site, weather permitting — this area's 60-65 inches of annual rain means we plan around dry-window forecasts more carefully than a drier climate would require. Larger or steeply-pitched roofs, or ones needing significant deck repair from moss damage, run longer. We give you a specific estimate at the inspection.

**What material should I choose?**

It depends on your budget, your home's style, how much moss/algae maintenance you're willing to commit to, and whether your property sits in wildland-urban interface terrain near Cougar, Squak, or Tiger Mountain, where Washington's Class A fire-rated assembly requirement can apply. Asphalt shingle is the most common and most affordable; cedar shake suits older homes and some HOA covenants; metal trades a higher upfront cost for 40-70 years with minimal moss-driven maintenance. See our material comparison guides for the full picture.

**Can you replace a roof that still has moss damage under it?**

Yes — that's exactly what a full tear-off catches. Moss and algae trap moisture against the deck for years before symptoms show up inside the house, and a recover-only job (shingling over the old layer) can't find or fix that. We check the deck from the attic side at the free inspection and tell you honestly if we find rot.

**Do you need a permit for my Issaquah reroof?**

Not always. A single-family composition-over-composition reroof of two layers or fewer typically doesn't require a City of Issaquah permit. Anything beyond that — sheathing replacement, structural changes, or a job outside city limits under King County DPER — does, applied for through MyBuildingPermit.com, and we pull it as part of the job when it's required.
