2026 Roof Replacement Cost in Fort Collins
A straightforward asphalt-shingle roof replacement in Fort Collins often costs less than people expect - but only when the bids being compared include the same roof size, materials, ventilation, flashing, permit work, and potential repairs.
Based on Drennen Custom Contracting's 2026 residential roofing sample through July, many ordinary shingle replacements have landed at roughly $500 to $675 per measured roofing square. A roofing square equals 100 square feet of actual roof surface. Small or simple roofs may fall below that range, while steep, tall, historic, highly cut-up, low-slope, or repair-heavy roofs can cost substantially more.
The ranges below are planning figures, not a quote. Every roof must be measured and inspected before a reliable price can be prepared.
A lower total is not automatically a better price. First confirm that each contractor measured the same roof area and included the same code work, materials, accessories, ventilation, permit, cleanup, and warranty.
Typical 2026 Planning Ranges
15 to 18 roofing squares
Approximately $8,500 to $11,500
Often a smaller one-story home, garage, or simple roof. Steep pitch, limited access, multiple layers, decking, or extensive flashing can move the price higher.
19 to 23 roofing squares
Approximately $10,000 to $14,000
A common range for modest Northern Colorado homes with ordinary access and limited special details.
24 to 27 roofing squares
Approximately $14,000 to $18,000
Common for medium-size homes. Ventilation corrections, wall flashing, skylights, chimneys, and decking become increasingly important at this size.
28 to 32 roofing squares
Approximately $17,000 to $22,000
Often a larger home or a roof with more hips, valleys, waste, stories, and accessory work.
40 to 46 roofing squares
Approximately $23,000 to $30,000
Large roofs can have a lower base cost per square, but complexity, height, steepness, safety requirements, and material handling can change the final price significantly.
These figures are based on a limited sample of Drennen projects and estimates, not every roof in the Fort Collins market. They should be reviewed and updated as material, labor, permit, disposal, and insurance conditions change.
What Does "Price Per Square" Mean?
A roofing square is 100 square feet of roof surface. It is not the same as the home's living-area square footage. A 2,000-square-foot house can have a roof measuring considerably more than 20 squares because of pitch, overhangs, garages, porches, hips, valleys, and waste.
A contractor may show several different square counts:
- Measured or tear-off squares - the existing roof surface being removed.
- Order or installed squares - measured area plus the material needed for cuts, hips, valleys, starter, and expected waste.
- Billable squares - the quantity used by the contractor's pricing system.
Before comparing bids, ask each roofer to identify which number is being used. Dividing a contract price by the wrong square count can make one bid look artificially high or low.
Recent Drennen Price Examples
The examples below are anonymized and rounded. They are included to show how real project totals vary. They are not offers to perform a different roof for the same amount.
Fort Collins - approximately 17 squares
Recent replacement totals: about $8,900 to $9,700
These were comparatively small residential projects with ordinary scopes.
Fort Collins - approximately 20 squares
Recent replacement totals: about $9,800 to $11,100
Differences included permit cost, roof details, material quantities, and accessory work.
Fort Collins - approximately 25 to 26 squares
Recent replacement totals: about $14,600 to $16,500
This size range can change substantially when ventilation, wall flashing, multiple stories, or decking are involved.
Fort Collins - approximately 30 squares
Recent replacement total: about $17,700
The final cost reflected the measured roof, system components, permit, and job-specific details.
Northern Colorado - approximately 45 squares
Recent replacement total: about $23,900
Large-roof pricing still depends on pitch, stories, roof shape, access, and accessories.
Windsor - 26.15 tear-off squares and 29.64 installed squares
Pre-project-specific-discount total: approximately $19,600
This was not a simple shingle swap. The scope included six sheets of roof decking, chimney counterflashing, extensive headwall and sidewall flashing, eight pipe jacks, two bath vents, a combustion-vent cap, roof-deck intake ventilation, exhaust ventilation, and an SBS Class 4 roof system.
The Six Biggest Roof-Cost Variables
1. Actual roof size and waste
Roof area is measured along the slope, not from the home's footprint. Hips, valleys, dormers, rake edges, and short courses require additional material. A simple gable roof normally wastes less than a complex roof of the same surface area.
2. Pitch, stories, and access
A steep or high roof requires more time, staging, fall protection, and careful material handling. Limited driveway access, protected landscaping, solar panels, fences, and neighboring buildings can also affect labor.
3. Tear-off and roof-deck condition
The existing roofing must usually be removed so the deck can be inspected. Soft, rotten, delaminated, undersized, or spaced sheathing may require repair or replacement. Because some conditions cannot be confirmed until tear-off, the estimate should state a clear unit price or change-order process for decking.
4. Flashing and penetrations
Chimneys, sidewalls, headwalls, skylights, swamp coolers, pipe jacks, bath vents, furnace vents, and roof-to-wall transitions are common leak locations. Reusing questionable flashing may lower the bid but increase future risk.
5. Ventilation and exhaust ducts
A new roof should not preserve an unbalanced attic ventilation system. Intake and exhaust should be calculated from the attic area and the listed net-free area of the selected vents. Bathroom and kitchen fans should discharge outdoors, not into the attic.
6. Permit, inspection, and local requirements
Fort Collins requires a roofing permit for repairs or replacement larger than 100 square feet. Current local requirements can affect impact resistance, underlayment, ice barrier, fastening, documentation, and inspection. Permit charges also vary with the jurisdiction and project.
What a Complete Roof-Replacement Estimate Should Include
- Removal of existing roofing to the roof deck, including disposal and site cleanup.
- Inspection of the exposed deck and a written price or process for unexpected sheathing repairs.
- Code-required ice-and-water barrier in applicable eaves, valleys, and vulnerable locations.
- Synthetic underlayment installed with appropriate cap fasteners.
- Drip edge at eaves and rakes where required.
- Starter shingles, field shingles, and compatible hip-and-ridge shingles.
- New or properly integrated pipe jacks, vents, flashing, and gutter kickouts.
- A calculated intake-and-exhaust ventilation plan.
- Protection for siding, windows, gutters, landscaping, and paved surfaces.
- Permit, inspection, taxes or use-tax treatment, cleanup, and magnetic nail collection.
- Manufacturer warranty information and the contractor's written workmanship terms.
How to Compare Two Roofing Bids Fairly
Do not compare only the bottom-line totals. Put the bids side by side and normalize the following items:
- 1Confirm the measured roof area and waste assumption.
- 2Confirm the exact shingle manufacturer, product line, impact classification, and ridge-cap product.
- 3Compare underlayment, ice barrier, starter, drip edge, valleys, wall flashing, and penetrations.
- 4Compare the ventilation calculation - not merely the number of vents.
- 5Identify open items such as decking, fascia, siding, skylights, gutters, or chimney repairs.
- 6Confirm permit responsibility, cleanup, warranty, payment terms, and change-order procedure.
A bid that omits $3,000 of necessary work is not truly $3,000 cheaper. It is an incomplete scope.
Why Drennen Publishes Price Information
Roofing prices should not be mysterious. Drennen Custom Contracting has served Northern Colorado since 1973, and our estimates are designed to explain the complete roof system - not simply the visible shingles.
As a general contractor, we can evaluate related decking, framing, fascia, soffit, siding, flashing, ventilation, and drainage conditions that a roof-only proposal may leave unresolved. Our goal is to help the homeowner understand what is necessary, what is optional, and what could change after tear-off.
