## Price

$250-$400 roofing square (100 sq ft) installed. 2026 published Boise-area installed pricing for 3-tab asphalt shingle (legacyroofingidaho.com).

## What's included

- On-site inspection and a written per-square price for 3-tab material before any work starts
- Full tear-off to the decking — 3-tab is not installed as a roof-over on an existing layer
- Deck inspection and replacement of any soft or delaminated sheathing, priced separately if found
- New synthetic underlayment across the full deck, with ice-and-water membrane at eaves and valleys
- 3-tab strip shingle install to manufacturer nail pattern and exposure spec
- New drip edge at eaves and rakes, new pipe boots and step flashing at walls and chimneys
- Ridge cap application and a magnet sweep of the yard and driveway for stray nails
- Haul-away and disposal of all old shingles and tear-off debris

## Process

01. **Inspection & written quote** - On-site look at the existing roof and a firm per-square price for 3-tab material and labor before anything is scheduled.
02. **Tear-off & deck check** - Full removal of the old roof down to the deck, with any rotten or delaminated sheathing flagged and priced before it's replaced.
03. **Underlayment & shingle install** - New underlayment, ice-and-water membrane where it's needed, and 3-tab shingles installed to the manufacturer's nailing and exposure spec.
04. **Cleanup & walkthrough** - Yard and driveway magnet-swept for nails, debris hauled off, and a final walkthrough before we call the job done.

## When it's needed

- Flat, single-tab shingles curling or cupping at the corners
- Granule loss showing bald patches or heavy buildup in the gutters
- Cracking across tabs from repeated summer heat/winter freeze cycling
- Roof is 15-20+ years old and was originally installed as 3-tab
- Tabs lifting or flapping in wind rather than lying flat
- A home sale or refinance inspection flagging shingle condition
- Matching 3-tab shingles no longer available to patch an existing roof

## FAQ

**How long does a 3-tab shingle roof actually last in Boise's climate?**

Most 3-tab roofs run 15-20 years here, on the shorter end of that range if the roof faces full south/west sun. Boise's summer thermal cycling — 100°F+ days into cold nights — ages the flat, single-layer mat faster than it would in a milder climate.

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

3-tab typically runs $250-400 installed per square versus $350-650 for architectural. The gap covers the laminate's extra material layer, higher wind rating, and generally longer service life — worth weighing against the upfront savings.

**Can I still buy 3-tab shingles in 2026, or are manufacturers dropping the line?**

It's a shrinking category — several manufacturers have discontinued or scaled back 3-tab production in favor of laminate lines. We'll confirm current availability and lead time for your specific job before you commit to it over architectural.

**Does 3-tab hold up to Treasure Valley hail the same as architectural shingles?**

No — 3-tab's thinner, single-layer mat bruises and cracks more easily under hail impact than a laminate shingle's reinforced mat. If hail risk is a bigger concern than upfront cost, architectural or Class 4 is the better fit.
