## Price

$450-$850 roofing square (100 sq ft) installed. 2026 published installed pricing for architectural (dimensional) asphalt shingle in the Boise/Treasure Valley area, translated from per-square-foot ranges (r2fidaho.com, idahoroofingcontractors.com); 3-tab shingle runs lower, roughly $350-$500 per square installed

## What's included

- On-site inspection and a written per-square price for architectural or 3-tab shingle before any work starts
- Guidance on architectural vs. 3-tab shingle trade-offs for your roof, budget, and how long you plan to stay in the home
- Full tear-off to the deck — never a roof-over on a second layer
- Deck inspection and replacement of any rotten or delaminated sheathing, priced as its own line
- Ice-and-water shield at eaves, valleys, and penetrations; synthetic underlayment across the field
- High-wind-rated shingle and fastening pattern to manufacturer spec, not a builder-grade minimum
- New starter strip, drip edge, and ridge cap shingles — not reused off the old roof
- Full site cleanup with a magnet sweep for dropped nails 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, and hand you a written per-square price for both architectural and 3-tab shingle so you can compare them side by side — no pressure, no charge.
02. **Permit and material order** — We pull the City of Boise (or your city's) reroofing permit and order your chosen shingle to the exact quantity your roof needs, including matching starter strip and ridge cap.
03. **Tear-off and install** — Full tear-off to the deck, sheathing repaired where needed, underlayment and flashing installed to spec, then shingles fastened in the pattern rated for the wind speeds this valley actually sees.
04. **Inspection and walkthrough** — Final inspection, magnet sweep for nails, gutters and landscaping checked for debris, and we walk the finished roof with you before we leave.

## FAQ

**What's the real difference between architectural and 3-tab shingles?**

Architectural (dimensional) shingles are heavier, carry a higher wind rating, and are the standard choice for most Treasure Valley homes today — they run roughly $450-$850 per square installed. 3-tab shingles are flatter, lighter, and less expensive at roughly $350-$500 per square installed, but carry a shorter rated lifespan and lower wind rating. Most homeowners upgrading from an aging 3-tab roof move to architectural; it's rarely the wrong call in a hail- and wind-exposed valley.

**Will asphalt shingles hold up to Boise's hail and wind?**

A properly fastened, high-wind-rated shingle handles the straight-line wind events and thunderstorm-outflow gusts this valley sees several times a year. Hail resistance depends more on shingle class than brand — we can walk through impact-rated options at the inspection. No shingle is hail-proof, but correct fastening and a wind-rated product materially reduce blow-off and granule loss after a storm.

**How long do asphalt shingles actually last in Boise's climate?**

Boise's swing from 100°F-plus summers to hard winter freezes, combined with intense high-altitude UV, is harder on shingles than milder climates — contractor sources put real-world lifespan at 15-25 years even on shingles rated for 20-30 years. Architectural shingles generally hold up longer than 3-tab under the same thermal stress.

**Do you install both 3-tab and architectural shingles?**

Yes. We'll give you a written price for both at the inspection so you can compare cost against expected lifespan and wind performance, rather than being steered toward one product by default.

## Signs you need this

- Shingles curling, cupping, or losing granules in patches
- Bald spots where granules have worn away, exposing the asphalt mat
- Missing shingles or exposed nail heads after a wind event
- Cracking concentrated around fasteners after repeated freeze-thaw cycles
- Visible sagging or an uneven roofline
- Roof is 20+ years old and was installed during the 1990s-2000s building boom
