Your Estimate
Tell us about your home
Enter the footprint of the roofed building area. Do not add the floor area of each storey. This calculator applies the selected pitch factor to estimate roof surface area. If you already have a measured roof surface area, do not enter it here without adjusting the calculation method.
Quick tip:
Use plans or a professional measurement for the pitch. You can compare scenarios if it is uncertain. Stay on the ground rather than climbing onto the roof to measure it.
Please enter valid dimensions or sq ft greater than 0.
Choose your roofing material
The amounts below are preset calculator assumptions in CAD per square foot of roof area. Confirm current pricing, product suitability, expected service life and written warranty coverage for the specific roof system.
SHINGLE OPTIONS
Architectural and luxury shingles are separate choices in this tool. Compare the exact product, roof details and included work when requesting a quote.
METAL AND SYNTHETIC
The tool includes standing seam metal and synthetic options. These categories need product specific specifications and installation details.
CEDAR AND TILE
Appearance, roof slope, supporting structure and ongoing care all matter. A calculator selection does not establish that a material suits the building.
Please select a roofing material.
Project details and add ons
A few last details so we can fine tune your estimate.
Record what is known.
Use the controls to compare removal, roof complexity, access and timing. Note any uncertain inputs for the assessment. Timing selections are planning scenarios; confirm actual availability directly.
This is a guide, not a quote.
This planning range uses your entries and the calculator assumptions. An assessment must confirm measurements, access, removal, the roof assembly and concealed repairs. Ask for an itemized written quote with current pricing and applicable taxes.

TURN YOUR ESTIMATE INTO A SCOPE
Tell us about your roof.
Share the material you are considering, the approximate roof age, known leaks and access constraints. Include which calculator inputs are uncertain so the assessment can address them.
A photo taken safely from the ground can help explain your question. Use the form below to request a conversation about the next step.
READ THE RANGE WITH THE INPUTS
What the estimate
can help you compare.
Change one factor at a time. Keep a record of the measurements and assumptions behind each result.
A lower result may represent less work, a different material or a different allowance. It does not establish that two proposals cover the same roof assembly. Use the calculator to prepare questions, then compare the measured scope in writing.
Removal and repairs
Record the known roof layers and any previous leaks. Concealed deck repairs need a clear allowance or approval process.
The complete assembly
Compare covering, underlayment, flashing, ventilation and drainage together. The visible surface is only part of the scope.
ACTUAL ROOFS
Look beyond the
square footage.
Roof planes, valleys and openings add details that need their own assessment. These photographs show roof features to discuss when preparing a scope.
A MEASUREMENT CHECK
One footprint.
Different roof areas.
A simple rectangular footprint measuring 40 by 30 feet covers 1,200 square feet. The slope increases the roof surface above that footprint.
| Example pitch | Same footprint | Approximate roof surface |
|---|---|---|
| 5/12 | 1,200 sq ft | 1,300 sq ft |
| 8/12 | 1,200 sq ft | 1,440 sq ft |
Geometry examples for a simple roof. They exclude overhang adjustments, waste and separate roof sections. Use measured dimensions for your property.
WHAT AN ASSESSMENT ADDS
Check the parts
the calculator cannot see.
Deck and support
Identify the existing substrate, its condition and any change needed for the proposed system. A cedar conversion may need different deck preparation from a replacement on sound sheathing.
Flashing and openings
Review valleys, walls, chimneys, skylights and roof penetrations. Identify which components will be replaced and which may remain.
Ventilation and drainage
Review how the assembly manages moisture and drains water. Confirm the intake and exhaust arrangement, gutters, outlets and any flat roof drainage details.
Access and protection
Plan material delivery, removal, disposal, work access and protection of the building and landscaping. Shared buildings also need occupant communication.
COMPARE WRITTEN PROPOSALS
Ask what each price includes.
| Scope item | What to confirm |
|---|---|
| Measurements and material | Roof areas, exact product, colour, profile and assembly specification. |
| Removal and disposal | Existing layers, handling, disposal and any retained components. |
| Decking and concealed work | Included repairs, allowances, unit pricing where applicable and written approval of extra work. |
| Roof details | Underlayment, flashing, ventilation, drainage, skylights and penetrations. |
| Project arrangements | Access, protection, cleanup, timing, weather arrangements and communication. |
| Commercial terms | Price, applicable taxes, payment schedule, quote validity, exclusions and actual warranty documents. |

Return to the calculator ↑ROOFING BUDGET QUESTIONS
Before you decide.
How accurate is this roofing cost calculator?
Use it for an early planning range. Its result depends on your measurements, selected options and preset assumptions. An assessment must establish the measured scope, current pricing and roof condition before you rely on a written quote.
Should I enter my home size or the roof surface area?
Enter the footprint of the roofed building area, counting it once. Do not add the floor area of each storey. The calculator applies the selected pitch factor. Entering a roof surface measurement as a footprint would apply the pitch adjustment again.
Can I compare asphalt, cedar, metal and flat roofing?
Yes. The tool includes architectural and luxury shingles, cedar, rubber shingles, standing seam metal, stone coated steel, synthetic roofing, clay, natural slate, SBS membrane and TPO. A selection does not confirm that the material suits your roof slope, structure or drainage.
Do I need to sign up to see the estimate?
No. You can calculate and compare without entering contact information. The email option prepares a draft addressed to the email you enter with contact@paragonroofingbc.ca copied. Review the recipients and message before sending. Downloading or printing the estimate does not submit a service request.
Does the estimate confirm taxes, permits or hidden repairs?
Confirm each of these in the written proposal. The calculator includes preset removal and optional work allowances, but it cannot inspect concealed decking or decide local project requirements. Ask what is included, excluded or subject to an allowance and how additional work will be approved.
Are the model life and term figures actual warranties?
No. They are retained comparison assumptions in the calculator. Request the actual product and workmanship warranty documents for the proposed roof. Review coverage, exclusions, registration, maintenance and transfer conditions. Model cost per year also excludes future maintenance, repairs and financing.
Should I repair my roof instead of replacing it?
A local defect can be a repair candidate when the surrounding roof is sound. Widespread deterioration or recurring problems in different areas may justify replacement. A leak or roof age alone does not answer the question. Ask the assessment to explain the condition and suitable options.
Can this calculator set the installation date?
No. The timing options are planning scenarios. Confirm availability, material lead times, site access and weather arrangements directly. For an active leak, call to discuss the problem and the appropriate next step.
