South Florida roof decision guide
For an aging asphalt-shingle roof, rejuvenation may fit when the shingles and deck remain sound. Widespread shingle failure, deck or structural damage, rot, or major storm loss can make replacement the right scope; localized issues may call for repair. Compare the supported facts, then get an inspection for a roof-specific recommendation.

Relative to replacement on a comparable roof; actual pricing depends on scope.
| Decision factor | Roof rejuvenation | Full roof replacement |
|---|---|---|
| Cost and schedule | ||
| Approximate costRelative to replacement on a comparable roof; actual pricing depends on scope. | About 15–30% of comparable replacement cost; roof size, pitch, and minor repairs affect price. | Typically the higher-cost scope on a comparable roof; final pricing depends on the written scope. |
| Treatment or project timing | Typically about 5–7 hours, or one day. | Schedule depends on the written scope and job conditions. |
| Worksite disruption | No tear-off or dumpster; the visit includes treatment and any agreed minor repairs. | Includes tear-off, disposal, and installation of a new roof; site impacts depend on the scope. |
| Roof fit and expected outcome | ||
| Best suited to | An aging asphalt-shingle roof with sound shingles and a sound deck. | A roof with widespread shingle-field failure or failed decking or structure; inspection confirms whether localized repair can address the damage. |
| Failure and damage signals | Not a fit for widespread shingle failure, deck or structural damage, rot, or major storm loss. | Widespread failure, failed decking or structure, rot, or major storm loss can make replacement the appropriate scope; localized damage may still be repairable. |
| Expected roof-life impact | May add 5–15 years on a suitable roof. This is conditional on roof condition, not a guarantee. | Starts a new roof system; ask for that system’s expected service life in the written proposal. |
| Warranty | The 5-year manufacturer warranty applies to the treatment product under its written terms; it does not warranty the whole existing roof or promise five added years of roof life. | Manufacturer and workmanship coverage depend on the selected system and its written terms. |
