Decision guide
Coat the roof or replace it?
The answer depends on what can be kept, what must be repaired, and how long the owner needs the roof to serve. Start with the roof condition, then compare full scopes.
Side by side
Questions that change the decision
A low coating price is not useful if the assembly below is failing. A replacement quote may be premature if much of the roof is sound.
The roof deck and most of the assembly are sound.
Structural or widespread material failures are present.
Wet areas can be located and repaired within a sensible scope.
Moisture is widespread or the source cannot be resolved.
Seams, flashing, and penetrations can be repaired and reinforced.
Failures are extensive or the assembly cannot be made reliable.
Preserving sound materials meets the owner’s planning horizon.
A new system better matches long-term capital plans.
Work can be staged around occupancy and roof access.
Replacement disruption is acceptable for a new assembly.

Ask what each proposal includes
Compare more than the top-line price. The scope should state how wet areas, drainage, penetrations, and future maintenance will be handled.
- Roof investigation and moisture findings
- Repair or tear-off boundaries
- Specified materials and application details
- Warranty terms and exclusions
- Schedule and building access plan
A practical rule
Restore a sound roof. Replace a failed one.
The on-site evaluation is where that distinction becomes clear. Sometimes a targeted repair is enough. Sometimes the roof needs replacement. A coating is useful only when it fits the condition of the existing assembly.
Questions and answers
Comparing the two options
Roof condition determines the recommendation. An evaluation can answer questions specific to your building.
Check my roof →Is coating always cheaper than replacement?
No. Restoration may cost less when the existing roof is sound and repairs are limited. Extensive wet materials or failed components can change the economics.
Does a coating count as a new roof?
A coating is a restoration system applied to an existing roof. Its scope, warranty, and code treatment differ from a full replacement and should be reviewed for the specific project.
What if only part of the roof is wet?
Localized wet areas may be repaired or replaced before restoration if the rest of the roof qualifies. The extent and cause of moisture need to be established.
