What’s the Right Way to Install Tile Roofing So It Doesn’t Leak?
Tile roofing is durable and long-lasting—but only if it's installed the right way.

If you're thinking about tile roofing for your North Georgia home, here's how we install it the right way to keep your roof watertight.

🛠️ Step-by-Step: How We Install Tile Roofing to Prevent Leaks
1. Proper Deck Preparation
It all starts beneath the tile. We inspect the roof decking for:
Soft spots or rot
Proper slope for water runoff
Secure nailing surface
We don’t install over bad wood. Ever.
2. High-Performance Underlayment
Tile itself isn’t waterproof—it’s a shell.
The underlayment is what keeps water out.
We use:
Premium synthetic or modified bitumen underlayment
Double-layered protection in vulnerable areas
Ice & water shield in valleys and around penetrations
This is your true water barrier.
3. Flashing, Flashing, Flashing
Flashing is where most leaks happen—especially around:
Chimneys
Skylights
Valleys
Roof-to-wall transitions
We install metal flashing with proper overlap and sealant, ensuring water sheds away from joints, not toward them.
4. Correct Tile Placement & Fastening
We never “nail through the tile” unless required. Instead, we:
Follow manufacturer fastening patterns
Allow proper spacing for expansion and water flow
Use foam or clips when needed to prevent tile shifting
Avoid over-tightening, which causes tile cracking
5. Ventilation & Drainage Matters
We ensure:
Proper attic ventilation to reduce moisture buildup
Correct tile lapping so water doesn’t backflow
Open and clean valleys for uninterrupted runoff
These final touches are the difference between a long-lasting tile roof and one that fails early.
FAQs: Leak-Free Tile Roofing
Q: Isn’t tile waterproof on its own?
A: No. Tile sheds water, but the underlayment and flashing do the real waterproofing.
Q: What causes tile roofs to leak?
A: Most leaks come from bad flashing, broken tiles, or old/degraded underlayment—not the tile itself.
Q: Can you fix a leaking tile roof without full replacement?
A: Often yes. We can replace damaged tiles, update flashing, or re-do underlayment in sections when needed.
