Repair when the problem is localized and the rest of the system has meaningful life left; replace when the waterproofing system — underlayment on tile roofs, the membrane or shingle field on others — is broadly failing, so that each repair only postpones the next leak. That is the whole decision in one sentence. The work is in determining honestly which situation your roof is in, and that takes an inspection, not a guess from the driveway.
Signs That Favor Repair
One identifiable failure point (a flashing, a valley, a vent, a damaged area from a tree strike); a roof in the first half to two-thirds of its expected service life; underlayment that is still pliable and intact when tiles are lifted in representative areas; and no history of recurring leaks in unrelated locations.
Signs That Favor Replacement
Leaks appearing in multiple unrelated areas; underlayment found brittle, cracked or torn wherever tiles are lifted; widespread previous patch repairs; decking deterioration in several locations; or a roof at an age where major repair spending is unlikely to be recovered in remaining service life.
The Middle Ground
Some roofs justify a substantial sectional repair — for example, re-doing one problem elevation or all valleys and wall flashings — to buy years of reliable service before a full replacement. Whether that math works depends on the roof's overall condition, which the inspection establishes.
Cost Perspective
Repairs cost less today; replacement resets the clock on the whole system. What makes repair a poor value is spending repeatedly on a system that is failing generally. What makes replacement premature is replacing a roof whose problem was one bad flashing. Photo-documented inspection findings are how you avoid both mistakes.
Naples and Southwest Florida Considerations
Hurricane exposure sharpens this decision: an aged, marginal roof is exactly the roof most likely to suffer in a wind event. Owners planning to keep a home long-term often choose replacement earlier here than they might elsewhere, while owners of newer roofs with isolated issues should not be talked into premature replacement.
Two Roofs, Two Different Answers
At Collier's Reserve, we advised against investing in sealant on a 30-plus-year-old tile roof — the tile surface was deteriorating enough that replacement was the more sensible horizon, and roof-age-related insurance considerations were part of the conversation too. At Seasons at Bonita, roughly five-year-old tile roofs with significant mildew buildup told a different story: substantial useful life remained, and soft washing followed by a protective sealant was the better investment. Same material, same general area, opposite recommendations — because the roofs were in different places in their service life.

Related Questions
How do I know if I need a roof replacement instead of a repair?
Age, extent of damage, and deck condition are the deciding factors. A roof nearing or past its expected service life, with damage spread across multiple areas, or with soft or rotten decking discovered during any repair, is typically better served by replacement than another patch. A single localized leak on an otherwise sound, mid-life roof is usually a repair. Craft Roofing (Florida Certified General & Roofing Contractor, CGC1540219 & CCC1336696) evaluates the roof in person before recommending either path.
How long does a roof replacement take in Naples, FL?
Most residential reroofs in Naples and Southwest Florida take a few days to about a week from tear-off to final inspection, depending on roof size, material (tile and metal generally take longer than shingle), and weather. Summer's near-daily thunderstorms can add delays since a roof mid-tear-off needs dry-in protection before rain arrives, so scheduling around the forecast is part of the process.
What roofing materials work best for a replacement in Naples?
Concrete and clay tile, standing seam metal, and architectural shingles all perform well in Naples when properly installed, with the underlayment beneath doing most of the real waterproofing work regardless of the surface material chosen. Tile is the traditional look for the area and highly durable; metal offers strong wind performance and a longer service life at a higher cost; shingle is the most economical option. The best fit depends on the home's structure, budget, and the owner's priorities.
What happens if rotten plywood is found during a reroof?
It's a common discovery once the old roofing material is torn off, especially on older homes or roofs with a history of slow leaks. Any soft or rotten decking is cut out and replaced with new plywood before the underlayment and new roofing go down — installing over compromised decking isn't done, since it can't hold fasteners properly and would undermine the new roof from day one. This adds modest material and labor cost but is standard practice, not a sign something went wrong.
Does a roof replacement in Naples require a permit?
Yes. Roof replacement is permitted work under the Florida Building Code, and Collier County requires a permit and inspections for reroof projects. Craft Roofing handles the permitting and inspection process as part of a replacement project.
