Removal of Clay Tiles
Clay tiles are typically attached to a roof using a combination of nails or screws, often in conjunction with battens (horizontal strips of wood or metal) and clips, or in some cases, with adhesives.
Here’s a more detailed explanation:
- Battens:Battens provide a framework for attaching the tiles, creating a level surface to secure the tiles to.
- Nails/Screws:Tiles are secured to the battens or directly to the roof sheathing (underlayment) using nails or screws.
- Clips:Clips can be used to further secure the tiles, especially in areas with high wind exposure.
- Adhesives:In some cases, adhesives can be used as a secondary fix, particularly where two mechanical fixings aren’t possible.
- Underlayment:A layer of underlayment (like roofing felt) is typically installed under the tiles to provide a waterproof barrier.
- Starter strips:The first row of tiles is often attached to starter strips, which are placed along the eaves (the lower edge of the roof) to ensure proper alignment and secure the bottom tiles.
- Interlocking Tiles:Some tiles are designed to interlock, which can reduce the need for nailing every tile.
- Specific Tile Types:The method of attachment can vary depending on the type of clay tile being used, so it’s important to follow the manufacturer’s instructions.
Installation Process of Clay Tiles
Installing clay tiles on a roof involves preparing the roof structure, installing underlayment, laying battens (if using), and then carefully placing and securing the tiles, starting with starter tiles and working upwards.
Here’s a more detailed breakdown of the process:
1. Preparation and Planning:
- Assess the Roof Structure: Ensure the roof frame is sound and strong enough to support the weight of the clay tiles.
- Remove Old Roofing: If there’s an existing roof covering, remove it completely.
- Reinforce if Necessary: Strengthen any weak areas of the roof deck or frame.
- Plan the Installation: Determine the tile type, layout, and any special requirements for hip and ridge tiles.
- Gather Materials: Obtain all necessary materials, including clay tiles, underlayment, battens (if needed), nails/clips, flashing, and any special accessories.
2. Install Underlayment:
- Apply Underlayment: Lay down a suitable underlayment (synthetic or felt) to provide a waterproof barrier between the roof deck and the tiles.
- Ensure Proper Overlap: Overlap the underlayment according to the manufacturer’s instructions.
- Install Drip Edge Flashing: Install drip edge flashing along the eaves and rakes to protect the underlayment and roof deck from water damage.
3. Lay Battens (If Applicable):
- Determine Batten Spacing:If using battens, measure and mark the proper spacing for the tiles and battens.
- Install Raised Battens opposed to Flush Battens:Lay the battens horizontally across the rafters, ensuring they are evenly spaced and secure. Raised Battens allow for better air and water flow
- Consider Airspace:
Allow for adequate airspace between the tiles and the roof deck for ventilation.
4. Install Tiles:
- Start with Starter Tiles:
Begin by installing starter tiles at the eaves, ensuring they are properly aligned and secured.
- Lay Tiles Row by Row:
Work upwards, laying tiles row by row, ensuring proper overlap and alignment.
- Secure Tiles:
Fasten the tiles to the battens or directly to the roof deck using nails or clips.
- Cut Tiles as Needed:
Cut tiles to fit around chimneys, vents, and other penetrations.
- Install Hip and Ridge Tiles:
Install hip and ridge tiles according to the manufacturer’s instructions and local building codes.
- Seal and Inspect:
Seal any gaps or penetrations with flashing and sealant, and inspect the roof for any issues or leaks.
Tips for a Successful Installation:
- Follow Manufacturer’s Instructions: Always refer to the tile manufacturer’s instructions for specific installation details.
- Work in Sections: Install the tiles in manageable sections to make the job easier and safer.
- Use a Level: Ensure the tiles are laid evenly and aligned using a level.
- Wear Safety Gear: Wear appropriate safety gear, such as gloves and safety glasses, when working on the roof.
- Consider Professional Help: If you are not experienced with roofing, consider hiring a professional roofer.
