- Multiple roof levels
- Skylights and roof access points
Existing Conditions:
- Tear-off vs. recover/overlay
- Deck repairs needed
- Insulation replacement
- Drainage modifications
Access Challenges:
- Building height
- Parking lot constraints
- Business operation requirements
- Material staging areas

Coating vs Replacement
Roof coatings can extend life at lower cost:
| Option | Per Sq Ft | Expected Life Extension |
|---|---|---|
| Acrylic coating | $2-3 | 8-12 years |
| Silicone coating | $3-5 | 12-18 years |
| Full replacement | $5-10 | 20-30 years |
Coating makes sense when the existing roof is structurally sound with 5+ years of remaining life.
Why TPO Works Well in Central Florida Heat
A flat or low slope commercial roof in Lake County spends most of the year under intense sun, high humidity and afternoon thunderstorms. TPO is a single ply membrane with a white reflective surface, so it reflects a large share of solar heat instead of absorbing it. For a warehouse, retail strip or office building, that can reduce the heat load on the roof deck and may ease the demand on rooftop air conditioning during the long cooling season. Actual savings depend on insulation, roof color, ventilation and how the building is used, so treat any figure you hear as an estimate until it is tied to your own utility records.
Florida adds conditions that matter more here than in cooler states. Heavy summer rain tests every seam, so heat welded seams and careful flashing at curbs, drains and penetrations deserve as much attention as the membrane itself. Wind uplift is the other concern. Attachment method, fastener spacing and perimeter detailing should be chosen to meet the wind requirements that apply to your building, and your contractor should be able to explain which approach they propose and why.
Cost follows these details. Thicker membrane, added insulation, tapered drainage and extra edge metal all raise the price, while a simple roof with few penetrations costs less to cover. When you compare bids, ask each contractor to name the membrane thickness, attachment method and flashing scope in writing so the numbers line up fairly.
