Start with conditions, not a product
Deck condition, underlayment quality, how flashing handles valleys and penetrations, ventilation, and whether the fastening pattern meets current Pinellas County wind requirements should drive the recommendation, since tile and shingle systems fail for very different reasons.
Build a complete scope
- What the deck looks like once the old system is stripped off
- How landscaping, pool cages, and neighboring units are protected mid-project
- Underlayment, flashing, and fastening rated for this wind zone
- Permit sign-off, disposal, and cleanup on a tight coastal lot
- What's excluded, warranty terms, and how change orders are priced
Clearwater context
In Florida the roof is the building's primary wind defense, and in Clearwater it is also an insurance question -- carriers look closely at roof age and condition, and coverage can turn on it, which makes proper documentation of a replacement as valuable as the work itself. Performance is mostly decided by what sits under the covering: deck attachment, a secondary water barrier, and the detailing at edges, ridges and penetrations, with the state's product approval system tying the specific assembly to the design pressure at the site. The local building mix then shapes the job. Postwar concrete-block houses often carry low-slope sections that fail by a different mechanism than pitched roofs do, barrier-island properties face the highest design pressures in the county, and in the condominium corridors the roof is usually the association's responsibility rather than an owner's.
