Final Strata Roofing Budget
|
Based on a Detailed Estimate
Planning ranges are not fixed quotes.
|
The selected system should be evaluated
against expected service life, maintenance
requirements and long-term reserve planning.
|
A complete budget should account for
roofing materials, labour, removal,
access, insulation, flashing, drainage,
permits where applicable and potential
deck repairs.
|
The most accurate budget comes from a
professional roof assessment and a
clearly defined scope of work.
