Two Roof Quotes, a $6,000 Gap: What Drives the Price Difference in Coeur d'Alene
Why does one roofing company quote your Coeur d’Alene replacement at $14,000 while another says $20,000 for what looks like the same job? That is a $6,000 gap on one roof. Most of the time the gap is not one company gouging you and the other giving you a deal. It comes from real differences in what each crew plans to do, what materials they spec, and what they left off the page. Learn to read those differences and you can compare bids on equal footing instead of guessing.
The Problem: Two Numbers That Won’t Line Up
You did the responsible thing and gathered more than one estimate. Now you are staring at two totals that feel worlds apart, and neither salesperson explained the gap in plain terms. The temptation is to assume the low bid is the honest one and the high bid is padded.
That assumption is where a lot of North Idaho homeowners get burned. A roof is not a single product with a fixed price. It is a system, and each contractor is quoting a slightly different version of that system. Two estimates that both say “asphalt shingle roof replacement” can describe very different amounts of work, material grades, and included protections.
Before you pick based on the bottom line, you need to know what is actually being compared. Our broader look at roof replacement cost in Coeur d’Alene covers the full range, but here we are focused on one thing: why two quotes for the same house disagree.
Diagnosis: The Five Things That Move the Number
When we see a large gap, it almost always traces back to a handful of line items. Here are the ones worth checking first.
1. Tear-Off Versus Overlay
Some low bids assume they will lay new shingles over your old ones. That skips the cost of removing the existing layer and hauling it away, which can be $1,500 to $3,000 on an average Coeur d’Alene home. An overlay looks cheaper today, but it hides whatever is rotting underneath and often shortens the new roof’s life. A full tear-off costs more up front because it does more.
2. Decking Repair Allowance
The wood under your shingles, called the decking, sometimes has soft or rotten spots that only show up once the old roof comes off. One contractor might build a realistic allowance into the quote, say $600 for replacing four sheets of plywood. Another leaves it out entirely so the total looks lower, then bills you a change order mid-project. Same roof, different honesty about the unknown.
3. Underlayment and Ice-and-Water Shield
At the eaves and in the valleys, North Idaho roofs need a waterproof membrane to handle melt and refreeze. A budget bid might use the minimum synthetic underlayment. A stronger bid runs peel-and-stick ice-and-water shield along the eaves and valleys. That upgrade can add $800 to $1,500, and in our climate it is not decoration.
4. Flashing, Vents, and the Details
Reusing old flashing around chimneys and walls saves money on paper. New flashing, fresh pipe boots, and proper ventilation cost more and prevent the leaks we get called about all winter. If one quote says “replace all flashing” and the other says nothing, you have found part of your gap.
Diagnosis Continued: Same Words, Different Work
Here is a realistic side-by-side for a 2,000 square foot Coeur d’Alene home with a moderately steep roof.
Quote A: $14,200
- Overlay, no tear-off
- Standard synthetic underlayment only
- No decking allowance
- Reuse existing flashing
- Builder-grade 3-tab shingles
Quote B: $20,400
- Full tear-off and disposal
- Ice-and-water shield at eaves and valleys
- $600 decking allowance included
- All new flashing and pipe boots
- Architectural shingles rated for higher wind
That is a $6,200 spread, and once you list it out, the two are clearly not the same roof. Quote B is doing more work with better materials in the exact spots our winters attack. Quote A may be fine for a house you plan to sell next spring, but it is not a like-for-like comparison.
The lesson is simple: a price gap is not proof of anything by itself. It is a question you have to answer by reading the scope. Our line-by-line breakdown of what each material and add-on costs helps you spot which upgrades are showing up in the higher bid.
The Fix: How to Compare Bids on Equal Footing
Start by getting both estimates in writing with itemized scope, not just a total. Then run this check:
- Match the method. Are both quoting tear-off, or is one an overlay? Convert them to the same approach before comparing dollars.
- Match the materials. Same shingle line, same underlayment, same flashing plan. Ask each contractor to spec the other’s materials so you see the true difference.
- Look for the allowances. A decking or unforeseen-repair allowance in one bid and not the other explains a lot of gaps.
- Ask what happens on surprises. How does each handle rotten decking found mid-job? A clear answer beats a low number.
If the quotes still differ after you have leveled the scope, that remaining gap is the real price difference between the two crews, and now you can weigh it against their reputation and communication.
When you are still not sure whether you even need a full replacement, a roof inspection is the honest place to start, and our guide on repair versus replace can save you from paying for more roof than the problem calls for. Homeowners across Coeur d’Alene and the surrounding Kootenai County area run into these exact gaps every summer.
When to Act
Late summer is the right time to compare quotes and schedule work. Crews have open calendars now, and finishing before the fall rains means you are not racing the first freeze. If you gather bids in August, you have room to ask questions, level the scope, and choose deliberately instead of under pressure.
Frequently Asked Questions
The cheapest bid saves me thousands. Why wouldn’t I just take it? Because the cheapest bid often leaves out the parts that cost money later. An overlay with reused flashing and no decking allowance can turn into change orders, early leaks, and a second replacement years sooner. Compare what is included, not just the total, and the “cheap” bid frequently is not the cheapest over the life of the roof.
Isn’t a high quote just a contractor charging more for the same thing? Sometimes, which is exactly why you level the scope first. Once both bids describe identical work and materials, any remaining difference is real pricing you can judge. Until then, a higher number often reflects more work, better materials, or honest allowances the lower bid simply omitted.
Do I really need ice-and-water shield and new flashing, or is that upselling? In North Idaho, the eaves and valleys take the worst of the freeze-thaw cycle, and old flashing is where a large share of the leaks we repair begin. These are not luxury add-ons here. If one quote includes them and another does not, that is a difference in protection, not just price.
