How Much Does Roof Replacement Cost in Boise?
Real numbers from actual Treasure Valley roof replacement projects.
Your roof is leaking, or the shingles are curling up, or maybe your insurance adjuster just told you it's time for a new one. Now you're wondering what this is going to cost.
Here's the thing about roof replacement cost in Boise — there's no single answer because every home is different. But you're not here for "it depends." You want actual numbers you can work with.
So let's break down what roof replacement actually costs in the Treasure Valley, what affects the price, and what you should expect when you get quotes from roofing contractors in Boise.
The Average Roof Replacement Cost in Boise
Most homeowners in Boise spend between $8,000 and $15,000 for a complete roof replacement with standard asphalt shingles. That's for an average-sized home (1,500-2,000 square feet of roof area).
Smaller homes with simpler rooflines might come in around $6,000-$8,000. Larger homes with multiple levels, steep pitches, or complex layouts can easily push $18,000-$25,000 or more.
Here's where it gets tricky: online calculators will tell you the national average is $5-$8 per square foot. That's not wrong, but it's not the full picture. In Idaho, when you factor in labor costs, disposal fees, and local building codes, you're looking at closer to $400-$600 per roofing square (a roofing square is 100 square feet).
So if your roof is 20 squares (2,000 sq ft), you're looking at $8,000-$12,000 for materials and labor with mid-grade asphalt shingles. Premium materials or specialty work will push that higher.
What Actually Affects Your Roof Replacement Cost
Every Boise roofer you call is going to give you a different number. That's because these factors change the scope of work dramatically:
Roof Size and Pitch
Bigger roof, more materials, higher cost. Pretty straightforward.
But pitch matters too. A steep roof is harder and more dangerous to work on, which means more labor hours and safety equipment. A 12/12 pitch (very steep) can add 30-50% to your labor costs compared to a gentle 4/12 pitch.
Roofing Material You Choose
Asphalt shingles are the most common in Boise because they're affordable and handle Idaho weather well. But you've got options:
- •Architectural asphalt shingles: $350-$500 per square (the standard choice)
- •Premium designer shingles: $500-$700 per square (better warranties, longer life)
- •Metal roofing: $700-$1,200 per square (lasts 50+ years, great for snow)
- •Tile roofing: $1,000-$1,800 per square (mostly on high-end homes)
Most people in the Treasure Valley stick with architectural shingles. They look good, last 20-30 years, and don't break the bank.
Condition of the Roof Deck
If your plywood decking is rotten or water-damaged, it needs to be replaced before new shingles go on. Most quotes assume the deck is solid. If it's not, expect to add $50-$100 per sheet of plywood that needs replacing.
A typical roof might need 5-10 sheets replaced. That's an extra $500-$1,000 you didn't plan for. This is why contractors can't give you a final price until they tear off the old roof and see what's underneath.
Layers of Old Roofing
Idaho building code allows up to two layers of shingles, but most roofers (and we agree) recommend tearing everything down to the deck for a proper job.
If you've got two layers of old shingles, that's double the disposal weight and double the labor to remove. Tear-off and disposal can add $1,000-$3,000 depending on the size of your roof.
Complexity and Obstacles
A simple ranch-style home with one roof plane is cheaper to re-roof than a two-story with dormers, valleys, skylights, and multiple chimneys. Every penetration, every angle, every transition adds time and materials.
If you've got a lot of roof vents, satellite dishes, or solar panels, those all have to be worked around or temporarily removed. It adds up.
Why Boise Roofing Quotes Vary So Much
You'll call three contractors and get three wildly different prices. It's not random.
Some roofers use cheap materials and cut corners to win on price. Others include extras like upgraded underlayment, better ventilation, or longer warranties. You're not comparing apples to apples unless you dig into what's actually included.
Also, bigger roofing companies have more overhead — trucks, insurance, payroll, marketing. That gets passed to you. Smaller crews can charge less because they've got lower expenses. Neither is inherently better or worse, but it explains the price gap.
Here's what matters: make sure every quote includes tear-off, disposal, new underlayment, drip edge, valley metal, ridge vent, and cleanup. If someone's quote is way lower, find out what they're skipping.
