The covering comes off and the soft deck runs beyond the visible stain. If your roofing contractor replacement estimate has no measurement or approval method for that extra work, the crew is stuck with an open roof.
Inspect the roof first. Define the assembly. Price the work in the order the crew will remove and rebuild it. Set the concealed-deck rule before anybody starts tearing off.
Inspect the roof before building the price
Roof area does not explain the whole job. Edges, valleys, penetrations, wall junctions, height, slope, access, staging, and the debris route all affect labor.
Walk the property with a survey sheet. Match every measurement, note, and labeled photograph to a roof plane or building elevation.
Sketch and measure every roof plane
Draw each plane. Record its length, width, and slope. Keep the measurements used for the takeoff instead of writing one unexplained area total.
Measure eaves, rakes, ridges, hips, and valleys separately. Mark dormers, chimneys, skylights, vents, curbs, walls, and other penetrations. Record the dimensions needed for membranes, flashings, and accessories.
Look at drainage. Mark gutters, scuppers, drains, crickets, and low areas. Note where the replacement needs a specific detail rather than standard field installation.
Take wide photographs of each plane and elevation. Add close photographs of visible damage, penetrations, edges, and wall junctions. Give each photograph the same location label used on the sketch.
Walk the access and debris route
Choose where the delivery will land. Mark where materials can be staged. Check the route from the truck to the roof and from the roof to the dumpster or roll-off.
Record restricted driveways, landscaping, neighboring property, overhead obstructions, gates, entrances, and areas that need protection. If a lift, scaffold, hoist, or temporary protection system is needed, put it in the job worksheet.
Do not assume the dumpster will fit where you want it. If it must sit farther away, the crew has a longer debris route. That is tear-off labor, not an office surprise after the job.
Split visible facts from concealed conditions
Write what you saw and how you saw it. Use direct notes such as visible from attic, observed at eave, or concealed until tear-off.
The deck may be covered. Flashing may run behind siding. Previous repairs may hide a wider defect. The number of existing roof layers may also remain uncertain away from exposed edges.
Each unknown needs an assumption or a written process for handling what the crew finds. Mark those decisions on the survey before you build the price.
Run the U.S. jurisdiction check before final pricing
Construction licensing requirements and building permits are separate questions. Do not assume one approval answers the other.
Find the regulator for the roofing scope
Start with the directory of state governments (opens in a new tab) and follow it to the official agency that regulates contractors in the state. Then use the directory of local governments (opens in a new tab) to check whether a city or county authority also regulates the work.
Ask each identified regulator whether the roofing scope falls under a contractor classification it controls. Confirm the roofing classification, who may contract for or perform the work, and what rules apply when you use subcontractors. Record the agency, answer, and contact in the job file before you issue the estimate.
Check permits and inspections separately
Use the directory of local governments (opens in a new tab) to find the building department responsible for the job address. Ask that department whether the stated replacement scope needs a permit or inspection and who may hold the permit.
Put the responsible party in the estimate. State whether permit and inspection costs are included, excluded, or paid directly by the customer. Do not leave that decision for the crew.
Transaction-tax treatment can vary by jurisdiction. Check it with your accountant before formatting the customer total. Do not use the IRS for a state or local sales-tax question.
Lock the removal and replacement scope
Choose the work before costing it. A material takeoff depends on the assembly you have agreed to install, and installation labor depends on its details.
Write the roof build-up from the deck outward. Do not treat the finished covering as the complete specification.
State what tear-off includes
Name the existing covering and the layers assumed in the base scope. List the underlayments, flashings, vents, fasteners, damaged accessories, and attached materials included in removal.
Say what stays. The estimate should tell the crew whether gutters, skylights, wall flashing, satellite equipment, vents, and other components will be removed, reused, replaced, protected, or excluded.
If the survey could not confirm the full removal scope, state the assumption. Connect a different site condition to the stop-work and change-order process.
Define an acceptable deck
Name the deck material you expect to find. Describe the condition that can remain and the condition that calls for refastening, repair, or replacement.
Avoid a line such as replace bad wood. The crew needs a usable test. The customer needs to know how the affected area will be measured and recorded.
State whether deck inspection and refastening are included. Keep localized repair separate from full replacement. The tasks use different labor and materials.
Specify the new assembly
List the membranes, underlayments, covering, edge components, valleys, flashings, ventilation, fasteners, sealants, and accessories. Match each wall junction and penetration to its installation detail.
Record the manufacturer and product specification where the customer has selected them. If a product remains open, state the selection method rather than guessing at a material cost.
Build the takeoff from the accepted assembly. Before sending the order, use the roofing material order checklist to match purchasing against the estimate.
Choose the concealed-deck method before tear-off
Deck condition can remain hidden until the covering is removed. The amount may be unknown, but the pricing and approval method should not be.
Choose one commercial method and write it into the roofing contractor replacement estimate. Tell the customer where the measured quantity and selling price will appear, and tell the crew when the base scope ends.
Include a fixed quantity in the base price
State the deck quantity or task included in the base price, the material covered, and how the crew will measure its use. The customer sees the included quantity and its scope in the accepted estimate.
State how unused included work is treated. Say whether the fixed base price remains unchanged or whether unused work creates a credit. Once the included quantity is exhausted, stop treating more deck work as part of the base scope.
If added work will use an agreed unit selling price, print that price and its measurement basis in the estimate. Show the measured excess and added selling price on the change order.
Use an allowance that gets reconciled
An allowance is a stated budget inside the estimate, not a promise to complete an unknown amount of work. State what labor, material, handling, and disposal the allowance may cover.
After exposure, measure the accepted work and calculate its selling price using the method written in the estimate. Show the allowance, actual measured selling price, and resulting credit or addition on the customer document.
Do not switch from an allowance to an unlisted unit price after tear-off. The reconciliation method belongs in the accepted estimate.
Exclude unconfirmed replacement and issue a priced change order
You can exclude concealed replacement from the base price. State that the crew stops at the affected area while you document and price the added scope.
The change order should show the exposed location, agreed measurement, deck specification, added scope, selling price, schedule effect, and customer approval. Get approval before the crew covers the evidence or performs the extra work.
Use the same rule if another existing roof layer appears. The original layer assumption marks the end of the base tear-off scope; the added removal starts on the priced change order.
Build roof replacement pricing in crew sequence
A useful worksheet follows the job. Setup comes before tear-off. Deck work comes before the new assembly. Cleanup and disposal stay attached to the work that caused them.
Keep roofing labor and materials separate internally even if the customer sees a grouped price. Use current supplier quotes and your own crew records. Do not turn an old roof total into a rate card.
Cost setup, protection, and tear-off
Estimate labor for delivery coordination, property protection, setup, removal, lowering, sorting, loading, and cleanup. Adjust the crew time for height, slope, access, roof complexity, and debris distance.
Add dumpster or roll-off costs, hauling, disposal, and crew handling as direct job costs when the replacement creates them. Do the same for temporary protection and access equipment used only on that roof.
Cost deck work separately
Use separate worksheet lines for inspection, refastening, localized repair, and replacement. Add material, labor, fasteners, equipment, debris handling, and disposal to the task that causes each cost.
Keep confirmed base work apart from concealed work that may become a change order. The separation makes approval cleaner and gives you a usable estimated-to-actual comparison later.
Cost installation from the specified assembly
Estimate the labor needed for deck preparation, membranes, field covering, edges, ridges, hips, valleys, penetrations, wall junctions, ventilation, flashings, and final cleanup.
Use your own records from jobs with comparable details. Roof area alone does not describe the time needed around a chimney, skylight, valley, or wall.
List every material in the assembly. Include membranes, flashings, ventilation components, fasteners, sealants, accessories, and delivery. Record reused components separately so the crew does not order replacements by mistake.
Add the remaining job costs
Add access equipment, delivery, permits, disposal, and subcontracted work caused by this job. Keep each cost in a plain bucket that can also be used after completion.
Allocate business overhead using the method already set for your company. Then add profit. Do not hide direct roof costs inside overhead just because they were missed during the site visit.
Add roofing markup without confusing it with margin
Markup is the amount added to cost to produce a selling price. Margin is profit divided by the selling price. Mixing them can leave a job looking healthy on the estimate and weak in the accounts.
Apply markup to the full cost base used by your business. That base must account for the labor, materials, equipment, disposal, subcontractors, permits, and allocated overhead you intend to recover.
The markup versus margin guide gives you the formulas to use with your own figures.
Worked example: Oak Street house example
This is the house electrical example, not a roofing price or rate card. All figures are sample currency units.
R. Chen at 14 Oak Street received Quote Q-1847 for a bathroom exhaust fan, ducted through the roof, and four LED downlights. The quote total was 1,105. The job cost measured against that original quote was 850, leaving profit of 255.
Margin was 255 divided by 1,105, or about 23%. Markup was 255 divided by 850, or 30%.
The ceiling was lined and the quote excluded chasing. Extra cable and chasing were approved on site as a 160 change order, taking Invoice INV-1847 to 1,265. The costs of that change order are not given, so do not calculate profit using the invoice total or combine 1,265 with the 850 original job cost.
Use the same discipline on a roof. Calculate roofing markup from the cost base it belongs to. Calculate final job profit only when the costs for all approved changes are known.
Write the customer-facing roofing contractor replacement estimate
The customer document should describe what will happen from site setup through final cleanup. It should also show what happens when the roof reveals work that could not be inspected beforehand.
Use clear scope sections for tear-off, deck work, installation, access, disposal, and exclusions. Keep internal production assumptions in the worksheet, but put every assumption that can change customer scope or price in the estimate.
Include product specifications, components to be reused, permit responsibility, payment stages, schedule conditions, and the acceptance method. If the document is called an estimate, proposal, or quote in your business, check any required notices with the public body that regulates your work before issuing it.

Read the finished document against the site sketch. Every roof detail that changes labor or material should appear in the scope, worksheet, or stated exclusion.
Record added deck work while the roof is open
Take labeled photographs before removing the affected deck. Mark the location on the roof sketch and record the exposed condition against the crew's job reference.
Measure the area using the method accepted with the estimate. Record the deck material, fastening work, added disposal, and crew time against the same location.
Attach that field record to the change order. Keep the photographs, measurement, approval, purchase record, and crew entry together so the final invoice can point to the work performed.
Turn the accepted estimate into the job record
Carry the estimate reference into crew time, purchases, deliveries, equipment, disposal tickets, subcontractor invoices, and change orders. Keep the same tear-off, deck, installation, and added-work cost buckets throughout the job.
After completion, compare estimated and actual cost by bucket. Check where labor changed, where material quantities moved, and whether access or disposal matched the site assumptions. The job-costing guide explains how to make that comparison from completed records.
Common questions
Can I prepare the estimate from aerial measurements alone?
Aerial measurements can support the takeoff, but they do not show every access restriction, concealed condition, debris route, or reusable component. Visit the property before final pricing and record the conditions that can change crew time or scope.
Should customer-supplied roofing materials reduce the scope?
List exactly what the customer will supply and who checks quantity, specification, condition, delivery, and shortages. Keep your labor, handling, protection, accessories, disposal, overhead, and profit visible in your cost worksheet.
Should sales tax be included in the estimate total?
Use the treatment that applies to the job location and your business. Ask your accountant before issuing the roofing contractor replacement estimate, then label the sales tax clearly rather than mixing it into labor or material cost.
