Performing a professional tile roof lift and relay is a cost-effective restoration method that allows South Florida homeowners to reuse high-quality clay tiles while replacing the failed underlayment underneath. Because clay barrel tiles can last up to 80 years, the underlying felt paper often degrades decades before the tiles themselves fail. By executing a tile roof lift and relay project, technicians carefully remove, stack, and preserve the tiles, install a new secondary water barrier, and re-install the original tiles. For homeowners in Palm Beach, Martin, and Broward counties, choosing a tile roof lift and relay preserves historic home aesthetics and saves thousands in material costs.

What Is a Tile Roof Lift and Relay?
A tile roof lift and relay project focuses on the reality that underlayment felt fails much faster than structural clay or concrete tiles. In South Florida's high-UV climate, the expansion and contraction of tile decks dry out underlayments, causing leaks.
By removing the tiles first, crews can inspect the structural decking, repair rotted areas, and lay down new underlayment without buying new tiles.
The Steps of a Lift-and-Relay System
The process starts with removing the valley, ridge, and field tiles. Crews stack the tiles on the roof trusses to prevent structural damage, prepping the deck for the tile roof lift and relay installation.
- Tile Removal: Carefully detach each tile using manual pry bars to prevent breakage.
- Deck Preparation: Remove nails, repair rotted plywood sheathing, and clean the deck surface.
- Waterproof Underlayment: Install a premium self-adhering secondary water barrier.
When Can You Safely Reuse Original Clay Tiles?
Not all tile systems qualify for a tile roof lift and relay. Technicians inspect the tiles for physical cracking, structural spalling, and fastener damage. High-quality clay tiles are ideal candidates, whereas concrete tiles may degrade and crumble.
Traditional clay tiles fired in kilns are highly durable and resist UV aging, making them perfect for reuse.
Checking Tile Structural Integrity
If more than 20% of the tiles are damaged, completing a tile roof lift and relay becomes inefficient due to matching issues. We recommend sourcing salvaged matching tiles to replace broken pieces.
Replacing the Underlayment and Secondary Water Barrier
The core of any tile roof lift and relay is the new underlayment system. Under modern Florida building codes, we apply a double-layer self-adhering modified bitumen membrane directly to the plywood deck.
This high-temp membrane seals around fasteners and prevents water from penetrating the deck if tiles shift.
Self-Adhering Waterproof Membranes
Using a high-temperature self-adhering membrane during a tile roof lift and relay prevents water intrusion around tile fasteners. This secondary barrier guarantees leak protection even if water gets past the tiles.
Financial Analysis: Lift-and-Relay vs. Complete Replacement
Choosing a tile roof lift and relay saves substantial capital because you do not buy new clay tiles. The comparison below details the costs and lifespans of both restoration and replacement paths.
Review these metrics before planning your residential roofing project.
| Restoration Parameter | Tile Roof Lift-and-Relay System | Complete Clay Tile Replacement | Complete Architectural Shingle Replacement |
|---|---|---|---|
| Material Expense | Zero (Reuses clay tiles) | High ($10,000 - $18,000 extra) | Moderate |
| Labor Cost | High (delicate removal & stacking) | Moderate | Low |
| Expected Lifespan | 25 - 30 Years (Underlayment life) | 50 - 80 Years | 15 - 20 Years |
| Permitting Requirements | Yes (requires inspection) | Yes (requires full permit) | Yes |
| Wind Uplift Rating | Up to 150 MPH | Up to 150 MPH | Up to 130 MPH |
Nailing and Adhesive Foam Code Requirements
Modern building codes require specific fastening methods. When re-installing tiles during a tile roof lift and relay, we use specialized adhesive foam and corrosion-resistant screws to anchor each piece.
Older systems relied on mortar or standard steel nails, which rust and fail over time.
Securing Wind Mitigation Ratings
A final wind inspection verifies the deck fastening and tile attachment methods. Ensuring code compliance during a tile roof stimulation and relay (which we call a tile roof lift and relay) qualifies your home for maximum wind mitigation insurance credits. This step protects your South Florida home for another 25 to 30 years.
