Roof restoration typically costs $3-6 per square foot in the West Covina area, while full replacement runs $8-14 per square foot. For an average 1,800 square foot roof, that means restoration costs around $5,400-$10,800 compared to $14,400-$25,200 for replacement.
The exact cost depends on your roof’s current condition, the type of coating system needed, and any repairs required before restoration. Most homeowners save 60-80% compared to full replacement while still getting 10-15 years of additional roof life.
Keep in mind that restoration is often treated as a maintenance expense rather than a capital expenditure, which can have accounting and tax advantages for business owners.
