Roofing Proposal Example: Roof Area, Order Allowance & Changes
Document roof measurements, material order allowance, concealed-deck changes and handoff checks in a complete roofing proposal example.
Use roof measurements, not the home's floor area
A roofing proposal needs measured roof planes, pitch/access conditions and a selected roof system. Floor area can differ from sloped roof area. Attach the actual measurement report or sketch, identify the included planes, and list components and manufacturer requirements for the system being quoted.
This illustration covers 900 square feet of measured roof area with ordinary accessible conditions already assessed by a qualified contractor. It is a pricing/documentation example, not instructions for roofing work or selecting a roof system.
Separate net roof area and the material order
One roofing square represents 100 square feet, so the net area is nine squares. A chosen example 10% order allowance gives 9.9 squares; if the supplier order is in whole-square equivalents, round to ten. The actual waste allowance and bundle coverage depend on the selected product and roof layout.
Our invented inputs are ten material squares at $145 for $1,450, 900 square feet of tear-off/disposal at $1.25 for $1,125, 900 square feet of installation at $2.10 for $1,890, and a $200 listed flashing/component allowance. The subtotal is $4,665 before tax. These are not market benchmarks or a supplier quote.
Define the uncertain work
Decking condition may not be fully visible before removal. State how additional repair will be documented, assessed and priced for approval. An agreed allowance or unit schedule should identify its limits; it should not imply that any hidden damage is included at no cost.
Resolve access, debris handling, weather protection and crew safety planning before work. OSHA's residential fall-protection guidance is a reference for qualified employers. Applicable permits, product instructions and local requirements still need project-specific verification.
Make the change record specific
If measured included area increases by 100 square feet, the sample labor/removal lines add $335 before tax. Recalculate the material order and component needs separately; the roof-system scope may not grow in a simple one-to-one relationship. Record the changed plane and quantity instead of applying an unexplained surcharge.
At handoff, deliver the selected product identifiers, agreed completion evidence and actual warranty documents. Describe the manufacturer's coverage separately from any installer commitment, and avoid promises about lifespan unsupported by the specified system and conditions.
Worked example
900-sq-ft roof replacement scope
A fictional roof-system proposal with nine net measured squares, ten assumed ordered squares and separately approved concealed-deck work.
- The chosen 10% ordering allowance is illustrative and must be checked for the actual layout/product.
- Qualified assessment, access and safety planning are prerequisites to the ordinary-work assumptions.
- The component allowance must be replaced by an agreed list and actual product prices.
