Tile Roofing Batten System Installation: A Complete Guide for Colorado and Georgia Homes

Installing tile roofing with a batten system is a proven method for maximizing roof durability, water shedding, and thermal performance—especially in regions like Colorado and Georgia where hail, freeze-thaw cycles, and heat can challenge roof systems.

Here’s a clear, code-backed guide on how tile roofing batten systems are properly installed.

What Is a Batten System?

A batten system in tile roofing uses horizontal wood or metal strips attached to the roof deck. These battens:

• Support the tile rows.

• Create space for water drainage and ventilation.

• Allow for mechanical fastening without penetrating underlayment.

When Are Battens Required?

Battens are typically used when:

• The slope is over 3:12.

• Concrete or clay tiles are installed per manufacturer's specs.

• Ventilation under the tile is needed for thermal performance or moisture control.

The 2021 International Building Code (IBC) and National Roofing Contractors Association (NRCA) both recognize battens as a common method for tile attachment.

Key Installation Steps

1. Prepare the Deck

• Deck must be clean, dry, and solid—usually plywood or OSB.

• Install high-quality underlayment. In cold or high-slope regions, use a self-adhering ice and water barrier at the eaves.

2. Install the Underlayment

• Minimum two layers of ASTM D226 Type II (30-pound felt) or synthetic underlayment.

• Ensure underlayment laps run with slope, 3" horizontal and 6" vertical overlaps.

3. Install Battens

• Use treated wood battens (typically 1x2 or 1x3) or manufacturer-approved metal battens.

• Fasten battens securely to the deck using corrosion-resistant nails or screws.

• Space battens according to tile exposure length—commonly 13" to 14" for concrete tiles.

• Leave gaps at vertical laps for drainage and ventilation.

Ventilation Tip: Raised battens or vented battens allow air to flow beneath tiles, helping prevent condensation and ice damming.

4. Place and Secure Tiles

• Start at the eaves with a starter course.

• Hook-lock or mechanically fasten tiles to the battens per manufacturer specs.

• For steep-slope areas or high-wind zones, follow enhanced fastening patterns per the Tile Roofing Industry Alliance (TRI) guidelines.

Why Batten Systems Work So Well

• Drainage: Space between tiles and underlayment promotes water runoff.

• Ventilation: Reduces moisture buildup and cools the roof deck.

• Easier Repair: Individual tiles can be lifted and replaced without damaging underlayment.

FAQ

What type of nails should I use to fasten battens?

Use corrosion-resistant nails (hot-dipped galvanized or stainless steel). Length should allow at least ¾" penetration into the deck.

Do I need to install battens if I’m using a foam adhesive system?

No. Foam adhesive systems bond tiles directly to the underlayment, often used in low-slope applications. However, these are more common in Florida than in colder climates like Colorado.

Should battens be treated wood?

Yes. Always use pressure-treated wood battens to resist rot and moisture damage.

Can tile be installed without battens?

Yes, in some direct-deck applications with high-strength underlayment. However, battens are generally preferred in steep-slope or ventilated systems.
