How a Tile Roofing System Works
A tile roof is a water-shedding system, not a waterproof barrier. In typical rain, water flows over the tiles and off the roof. During Florida’s intense downpours or hurricanes, water runs beneath the tiles by design. That’s where the underlayment steps in as the primary waterproofing layer. A properly installed system—decking, underlayment, attachments, and flashing—can deliver 30–50+ years of performance. Cut corners, and leaks or tile loss can start within a decade.
Components of a Concrete Tile Roof System
Decking: The wood sheathing fastened to trusses; everything relies on this foundation.
Underlayment: A waterproof membrane beneath the tiles, critical for stopping leaks.
Attachments: Foam adhesive and screws securing tiles against wind uplift.
Flashing & Accessories: Metal valleys, drip edge, vents, and roof-to-wall transitions that seal vulnerable leak areas.
Concrete Tiles: Available in barrel, flat, or S profiles with various colors and finishes.
6 Must-Have Installation Details for a Fortified Tile Roof
To ensure your tile roof withstands Florida’s conditions, follow these non-negotiable installation standards.
Solid Decking
Replace any soft, rotted, or damaged sheathing to prevent weak spots. A strong roof starts with a secure deck. Insist on re-nailing the entire deck to the trusses. This ensures the roof resists wind uplift and stays stable.
Premium Underlayment
Florida’s code allows various underlayments, but only a thick, self-adhered membrane (80 mil or ~2.0 mm) can handle wind-driven rain and UV exposure. Thicker membranes offer superior durability and heat resistance. Ask your contractor for the exact brand and thickness—no vague promises. It is recommended that underlayment is not left open (exposed to the elements) for more than 2 weeks.
Full-Field Foam Adhesive
Florida’s minimum code may require foam adhesive only at eaves and the first two rows, but this leads to tile loosening around year 10. Ask for foam adhesive across the entire roof field for better tile stability, reduced chatter, and enhanced wind resistance.
Two Screws Per Tile
Nails loosen over time; screws don’t. Require two corrosion-resistant screws per tile to secure tiles against storm winds. Confirm this in writing. Don’t accept “one screw” or “nails” as substitutes.
All-New Metal Flashing & Accessories
Longevity hinges on details. Replace all flashing with custom-bent metal flashing—never peel-and-stick substitutes. Reusing old flashing is a recipe for leaks. Ask your contractor to detail their flashing plan and replace all accessories.
Flat/Low-Slope Tie-Ins
If your home has flat or low-slope sections meeting the tile roof, replace those membranes simultaneously. Transitions are common leak points, and flat roofs age faster than tile. Syncing replacements prevents future issues.
Pro Tip: Don’t let contractors hide behind “Florida Building Code compliance.” Minimum code isn’t enough for longevity. At Ignite Exteriors, we follow these standards at no extra charge - your contractor should be too.
Quick Homeowner Checklist (Copy/Paste Into Your Notes)
Deck: Full re-nail to trusses + replace any soft/rotted/damaged sheathing.
Underlayment: Self-adhered premium membrane; brand + product + thickness listed. (2.0mm or more)
Foam: Full-field foam.
Fastening: Two corrosion-resistant screws per tile.
Flashing: All new custom cut metal flashing and new accessories.
Tie-ins: Replace any flat/low-slope membranes that meet tile.
Proposal: All specs written on contract and ask for photos of each (no “as needed,” no vague “meets code”).
Wind Performance and Warranties
Tile systems can be engineered for high wind performance. In practice, many tile assemblies are engineered in the 100–120 mph range depending on profile and fastening but can meet 130-150 mph range if installed for longevity. Manufacturer warranties for tile generally cover product defects. Hurricanes and named storms are typically insurance matters, not manufacturer warranty. If you want a higher wind-warranty with hurricane coverage, ask us about metal tile options.
Maintaining Your Tile Roof
Concrete tiles are durable but not maintenance-free. To keep your roof in top shape:
Soft-Wash Cleaning: Use gentle, professional soft-washing to remove algae and organic buildup, especially in shaded areas. Avoid high-pressure washing, which can damage tiles.
Clear Valleys & Gutters: Ensure water flows freely during heavy rain to prevent backups.
Annual Inspections: Check hips, ridges, and penetrations yearly and after storms.
Limit Foot Traffic: Tiles can crack under careless walking, voiding warranties. Hire professionals for maintenance.
Lifespan of a Concrete Tile Roof in Florida
Tile Body: Typically lasts 30–50+ years with proper care.
Underlayment: Lasts 10–25 years, depending on quality. Many “tile roof replacements” are actually underlayment refreshes. Investing in premium underlayment delays costly repairs.
Choosing Colors & Profiles
Concrete tiles offer a wide range of colors and profiles (barrel, flat, or S). To avoid future headaches:
Choose classic colors less likely to be discontinued.
Save extra tiles post-installation for future repairs.
Expect slight shade variations if repairing tiles years later due to weathering.
When to Consider Metal Tiles
For some Florida homes, metal tiles are a better fit:
Higher Wind Resistance: Many metal tile systems boast 200 mph wind and hurricane warranties, far surpassing concrete.
Lower Maintenance: Metal tiles resist algae and require minimal upkeep.
Lighter Weight: Easier on framing, ideal for homes.
Color Stability: Metal tile colors are less likely to be discontinued, simplifying future repairs.
We install both concrete and metal tiles and can bring samples to help you decide.
Frequently Asked Questions
Is concrete tile good for hurricanes?
Yes, if installed with premium underlayment, full-field foam, two screws per tile, and new metal flashings. The system’s strength, not just the tile, determines storm performance.
Do I need structural upgrades for concrete tile?
Homes built for tile are usually fine. If your home has older framing or was designed for a lighter roof (shingles/metal), a structural evaluation is wise before switching to tile.
How do I keep my tile roof looking good?
Schedule soft-wash cleanings, keep valleys/gutters clear, and book annual inspections. Be cautious of foot traffic to prevent cracked tiles.
What fails first on older tile roofs?
Typically, underlayment, flashing, or attachments fail before the tile itself. That’s why we prioritize these components.
Can I match tiles years later?
Sometimes, but discontinued profiles or colors can complicate repairs. Save leftover tiles to ensure matches.
