Patio Lanais in Palm Beach & Broward
A patio lanai provides a covered outdoor living space designed specifically for the unique coastal environment of South Florida. Built with either an insulated aluminum roof structure or conventional wood-and-concrete framing, a lanai protects outdoor sitting and dining areas from intense solar heat, tropical rain, and insects while withstanding High-Velocity Hurricane Zone (HVHZ) wind conditions. Preventive Maintenance provides complete single-source contracting—handling design, structural plans, HOA approvals, permitting, concrete, roofing, electrical, plumbing, and HVAC—to build patio lanais, convert existing covered patios into fully enclosed rooms, or construct ground-up home additions across Palm Beach County and Broward County.
Key Takeaways
Who This Service Is For
This service is designed for single-family homeowners in Palm Beach and Broward counties who want to expand or improve their functional living space. A patio lanai is ideal if you want an open-air, shaded outdoor area that keeps off rain and solar heat without fully sealing the space from breezes.
If you already have a covered patio or slab with pavers and want to expand your indoor living area, a patio-to-room conversion provides an insulated, air-conditioned interior room. For homeowners who need entirely new square footage from the ground up—such as a new primary suite, expanded family room, or in-law quarters—a full home addition provides structural space tied directly into your home’s existing layout and utility systems.
What We Build
Preventive Maintenance handles three primary types of structural expansion projects:
1. Patio Lanais
A patio lanai extends your outdoor living area over an existing concrete slab or newly poured foundation. We construct lanais using either:
-
Insulated Aluminum Roof Systems: Light-weight panels engineered to deflect extreme heat and resist heavy rains, supported by heavy-gauge aluminum posts and structural beams.
-
Conventional Wood-and-Concrete Framing: Structural masonry or wood framing with a flat TPO membrane roof or a sloped concrete tile roof designed to match your existing home’s architecture.
2. Existing Patio-to-Room Conversions
If you have an existing covered patio or lanai structure, we can enclose the perimeter to create a fully conditioned interior sunroom or living area. This involves framing wall openings, installing HVHZ-rated glass windows and sliding doors, adding thermal insulation, extending electrical circuits, and integrating HVAC ductwork or mini-split cooling systems.
3. Home Additions
For expanded living needs, we construct full ground-up home additions. This includes foundation work, stem walls, structural concrete block or wood framing, full utility tie-ins (electrical, plumbing, and HVAC), interior drywall finishing, and matching roof structures (flat TPO or sloped concrete tile).
All projects feature engineered roof tie-ins using a structural ledger connection or direct joist and truss integration on the existing concrete tie-beam.
Comparing Outdoor Expansion Options
| Service Type | Primary Purpose | Roof & Structural Features | Climate Control & Utility Scope |
| Patio Lanai | Shaded, open-air outdoor living protection from rain and sun | Insulated aluminum roof or conventional flat TPO / concrete tile | Open-air design; optional outdoor lighting and ceiling fan electrical hookups |
| Patio to Room Conversion | Transforming existing covered slab space into fully enclosed interior room | Utilizes existing roof or upgrades to flat TPO / concrete tile; insulated walls | Fully air-conditioned (HVAC extension or mini-split), complete electrical, insulated glass windows |
| Home Addition | Adding brand-new ground-up indoor square footage to the residence | Integrated trusses/joists tied to tie-beam with flat TPO or sloped concrete tile roof | Complete indoor living space with dedicated HVAC, full electrical wiring, and optional plumbing |
Our Process
We manage every step of your project directly to maintain quality control, adhere to local building codes, and ensure accurate timelines.
-
Initial On-Site Inspection: We evaluate your existing foundation slab, pavers, soffits, fascia, electrical panels, and structural tie-beams to determine load-bearing capacity and tie-in points.
-
Design & Architectural Plans: Our team drafts architectural drawings and engineering plans tailored to your property lines, setback requirements, and structural specifications.
-
HOA Submission: If your neighborhood requires approval, we prepare and submit the necessary architectural review documentation, site plans, and material specifications on your behalf.
-
Municipal Permitting: We submit structural, electrical, mechanical, and plumbing plans to your local city or county building department to secure all mandatory building permits.
-
Structural Construction: We pour or modify concrete slabs, erect aluminum or masonry framing, install wall enclosures, and complete roof tie-ins to the existing home structure using certified ledger or tie-beam attachments.
-
Utility Integration & Systems: Our licensed technicians perform all rough-in and finish electrical work, plumbing connections, and HVAC duct or unit installations.
-
Inspections & Final Walkthrough: We manage all required municipal inspections throughout the build process and conduct a final walkthrough to confirm quality and completion.
Cost Considerations
Project costs depend on structural materials, square footage, whether a new concrete foundation is required, and the extent of electrical, plumbing, or HVAC integration.
| Project Scope | Estimated Cost Structure |
| Aluminum Lanai Structure | About $52 per square foot on an existing concrete slab |
| Conventional Wood & Concrete Lanai | About $65 per square foot on an existing concrete slab |
| Air-Conditioned Home Addition | About $250 per square foot (compared to about $350 per square foot for new home construction) |
| Patio to Room Conversion | Varies; no single per-square-foot price because cost depends on whether the roof and slab remain, glass window selection, wall insulation, electrical wiring, and HVAC requirements |
Average project sizes typically range from 12' x 20' to 20' x 20', though all builds are completely custom to your property dimensions.
Timeline, Permits, and HVHZ Standards
The average timeline for project completion is 3 to 6 months. This schedule accounts for the initial property inspection, engineering, drafting, HOA review periods, municipal permit issuance, material delivery, and physical construction.
Building in Palm Beach County and Broward County requires strict adherence to High-Velocity Hurricane Zone (HVHZ) building codes. Because our region experiences extreme solar heat, intense humidity, heavy rainfall, and hurricane-force winds (without snow or ice loads), structural integrity is paramount.
Preventive Maintenance holds 5 state contractor licenses and EPA/EPS certifications. We handle all plan submissions, permit applications, and structural engineering to guarantee that every roof tie-in, column, window, and wall enclosure meets or exceeds Florida Building Code standards.
