Decision Framework

When restoration wins. When it doesn’t.

Restoration Candidate

  • Wet insulation below 25% of total roof area
  • Deck structure is sound (no compression failure)
  • Existing membrane has not been patched more than 4× in 5 years
  • No structural wood rot or deck deterioration
  • Building will remain in service for 10+ years

Replacement Required

  • Wet insulation exceeds 25–30% of total roof area
  • Deck structure is compromised
  • Membrane is so severely deteriorated it cannot hold a coating
  • Building ownership plans redevelopment within 5 years
  • Code violations require full system upgrade

Not sure which category your roof falls into? Our free infrared moisture survey determines restoration candidacy definitively — before you commit to any scope or spend a dollar. If your roof cannot be restored, we tell you directly. No upsell. No pressure.

Tax Advantage

Section 179 makes restoration even more compelling.

Roof restoration typically qualifies as a deductible repair expense under Section 179 — meaning the full cost may be deductible in the year of installation. Full replacement must be capitalized and depreciated over 39 years. The after-tax cost advantage of restoration is even larger than the headline numbers suggest. Consult your tax advisor for specifics.

Restoration — Section 179
Fully deductible in year one
Replacement — 39-Year Depreciation
Capitalized, ~2.6% deductible per year

*Tax treatment varies by jurisdiction and situation. Consult a qualified tax advisor.
