Article: https://yenra.com/wiki/Cool_roof_air_temperature_reduction/

Purpose: prepare a comparable brief for roof contractors. Save this UTF-8 text file and enter one set of answers per proposal. Obtain a qualified roof assessment; this form is not an installation design.

Property/location and assessment date:
Roof area (state square feet or square metres), slope and current material:
Roof age, leaks, drainage and known moisture issues:
Insulation, occupied spaces below and cooling/heating equipment:
Contractor and date of condition assessment:
Exact manufacturer/product/color and CRRC ID:
Solar reflectance (0-1), initial / three-year weathered / interim Rapid Rating:
Thermal emittance (0-1), rating type:
SRI (separate index, not a reflectance fraction), rating type:
Substrate compatibility and written installation requirements:
Repair, preparation, insulation, flashing and disposal included:
Manufacturer warranty / installer warranty / exclusions:
Maintenance and recoating obligations:

ENERGY AND COST COMPARISON
Use the same building, weather and operation in baseline and proposed cases.
Baseline roof total installed price ($):
Proposed roof total installed price ($):
Extra cost = proposed minus baseline ($):
Annual cooling expense reduction ($/year):
Annual heating expense increase ($/year):
Annual maintenance difference, with sign explained ($/year):
Net annual benefit = cooling reduction - heating increase - extra maintenance:
Simple recovery years = extra cost / positive annual benefit:
Model author, weather period and assumptions:

Fictional illustration: $600 extra cost / ($90 cooling reduction - $20 heating increase) = about 8.6 years. Excludes discounting and changing prices. Your estimates are not guaranteed savings. Compare with expected roof service life.
Other options assessed, such as insulation:
Unresolved question / responsible person / evidence needed:
Decision and reason:
