Roofing prices per square — the real numbers, no guessing.
Real per-square pricing by roof pitch for GAF Timberline NS, HDZ, and UHDZ shingles — and what's included with every roof.
Price per square
A "square" is 100 square feet of roof surface. Your rate depends on your roof's pitch — the steeper the roof, the more it costs to work on safely. Multiply the rate by your roof's actual square count for a full-job price.
| Roof pitch | GAF Timberline® NS | GAF Timberline HDZ®Our standard | GAF Timberline UHDZ® |
|---|---|---|---|
| Low pitch | $400/sq | $450/sq | $500/sq |
| Medium pitch | $450/sq | $500/sq | $550/sq |
| Steep pitch | $500/sq | $550/sq | $600/sq |
Rough guideline only — your final price depends on your roof's actual measured size and condition, confirmed with a free on-site inspection.

What happens if we find something unexpected
Sometimes when we tear off old roofing, we find things that weren't visible before — rotted decking, structural damage, or something that doesn't meet current code. That's a normal part of roofing, not a bait-and-switch — no inspection, however careful, can see through existing shingles.
A legitimate change-order process should be in writing, priced and explained before that work continues — never a verbal add-on, and never a surprise showing up on your final bill. Here's how we actually handle it:
Work stops on the affected area
The moment we find something, we stop and assess it — we don't work around a real problem to save time.
Priced in writing, before we continue
Any real additional cost is a written change order you approve first — never something we just add to the final bill.
Documented, not a handshake
Change orders are tracked in our client portal, so there's a clear record of what was agreed to and when.
Not everything we find rises to that level. A handful of extra fasteners, a small strip of flashing, a couple square feet of minor deck repair — if it's small enough that it's not really a change to your project, we'd rather just take care of it than make a big deal out of a few dollars. Change orders are for real, priced changes to the scope of work — not every small thing a crew runs into on a roof.
Pricing questions
How much does a new roof cost per square in mid-Michigan?+
Our standard roof is GAF Timberline HDZ shingles at $450–$550 per square, depending on your roof's pitch — $450/sq for a low-pitch roof, $500/sq for medium pitch, and $550/sq for a steep roof. A "square" is 100 square feet of roof surface. Your total price is this rate times your roof's actual square count, confirmed on site.
How much do GAF Timberline NS and UHDZ shingles cost compared to your standard roof?+
Timberline NS (Natural Shadow) costs $50 less per square than our standard HDZ roof ($400–$500 per square by pitch), and Timberline UHDZ costs $50 more ($500–$600 per square by pitch). On a 25-square roof that's about $1250 less for NS or $1250 more for UHDZ. You can compare the shingles and see your own roof's price in our online estimator.
What warranty comes with a new roof from Walker's Quality Roofing?+
Every installation carries our 10-year workmanship warranty, which covers mistakes made during installation. Shingle (material) warranties come from the manufacturer, and GAF's System Plus warranty is available on qualifying GAF roofing systems because we're a GAF Certified contractor. The warranty that applies to your roof is spelled out in your written proposal.
How do I know which pitch category my roof is?+
Most standard homes fall into low or medium pitch. Very steep or walkable-only roofs are the steep category. Our online estimator measures your actual roof from satellite imagery and tells you which category applies, or you can ask during a free on-site inspection.
Are these prices final?+
No — they're the same real per-square rates our crews quote from, but your final price depends on your roof's actual measured size, condition, and any job-specific factors found during a free on-site inspection. Use our online estimator for a price range specific to your home.
What is a change order in roofing?+
A change order is a written, signed agreement for work beyond your original scope — with its own price — that both you and the contractor agree to before that work happens. A legitimate contractor never charges for a scope change based on a verbal conversation alone.
What happens if a roofer finds rotted decking during tear-off?+
It's normal — roofs hide things until the old material comes off, and no inspection can see through existing shingles. At Walker's, work on the affected area stops the moment something's found, and any real additional cost is priced and explained in a written change order before we continue. Nothing gets added to your bill based on a verbal agreement.
How can I avoid unexpected costs from a roofing contractor?+
Ask upfront how they handle unforeseen issues like rotted decking or structural damage. A legitimate contractor puts any real additional work in writing, with its own price, before continuing — never charges based on a verbal conversation, and never adds a surprise cost to a final bill you didn't agree to in advance.
