Step-by-Step Installation Guide

Now, let’s break down the installation process into manageable steps:

Step 1: Preparation and Safety

1. Assess the Roof Condition: Before you start, thoroughly inspect your roof decking for any damage or rot. Replace any damaged boards before moving forward.
2. Clear the Roof: Remove any debris, old roofing materials, and obstructions from the roof surface. Make sure the work area is clean and safe.
3. Set up Scaffolding or Safety Gear: If working at a significant height or on a steep roof, ensure you have scaffolding or safety harnesses securely installed before starting.
4. Weather Check: Always be mindful of the weather conditions. Do not work on the roof during periods of rain, high winds, or severe weather.

Step 2: Installing the Underlayment (or Felt Paper)

1. Roll out the Underlayment: Start at the eaves and roll out the underlayment across the roof surface, overlapping each strip by at least 6 inches. Follow the manufacturer’s installation instructions. Some underlayment materials require a certain overlap size, so double-check.
2. Secure the Underlayment: Use staples or roofing nails to secure the underlayment to the roof deck. Ensure that the underlayment is smooth and free from wrinkles or tears.
3. Cover the Entire Roof: Continue rolling out and securing the underlayment until the entire roof deck is covered.

Step 3: Installing the Battens (or Counter Battens)

1. Determine Batten Spacing: The batten spacing depends on the type and size of your roof tiles. Consult the tile manufacturer’s guidelines for precise spacing instructions. Measure accurately before installing battens.
2. Optional: Install Counter Battens: If needed, start by installing the counter battens. Counter battens are installed vertically, running from the eave to the roof ridge, over the underlayment. They help create an air gap under the tiles, which can improve ventilation and help to prevent condensation.
3. Install the First Batten: Start by installing the first batten along the eave. Ensure it’s straight and level. Use a level and a measuring tape. Ensure the batten is properly aligned and secured.
4. Install Subsequent Battens: Following the determined spacing, install the remaining battens across the roof. Use a chalk line to maintain straight lines and proper alignment. The spacing must be consistent to properly align the tiles in each course.
5. Ensure Proper Overhang: Check your specifications for overhang of the tiles. This is also a good time to install your drip edge if specified for your installation.
6. Secure the Battens: Use nails or screws to securely fasten the battens to the roof deck or counter battens. Ensure that each batten is firmly attached and does not wobble.
7. Check for Level: Periodically check the level of your battens to make sure you are laying a straight and even plane for your roof tiles.

Step 4: Laying the First Row of Roof Tiles

1. Start at the Eave: Begin laying tiles at the bottom edge of the roof, working your way up. This is called the eave course. Align the first row with the eave batten.
2. Install Eave Closures (if needed): Install eaves closures before the first row of tile is laid. These pieces are used to stop pests from making a home under the tiles.
3. Check the Overhang: Ensure each tile is properly positioned with the correct overhang. Use the manufacturer’s recommended overhang specifications as a guide.
4. Align the Tiles: Align each tile carefully, making sure that the spacing between the tiles is consistent.
5. Secure the Tiles: Depending on the tile type, you may need to use tile clips or nails to secure the tiles to the battens. Follow the manufacturer’s instructions. Many tiles have interlocking edges, but this will also be dependent on your particular installation.

Step 5: Laying Subsequent Rows of Roof Tiles

1. Overlap the Tiles: Each subsequent row should overlap the row beneath it. This overlap is crucial for water run-off and proper protection. Follow the manufacturer’s guidelines for overlap specifications.
2. Maintain Consistent Spacing: Keep the spacing between tiles consistent as you proceed up the roof. Use chalk lines and visual checks to maintain alignment.
3. Stagger Seams: Stagger vertical tile joints between rows for greater structural integrity and a better finished appearance. For most tiles, this means the seams of the course will be offset from the course below it.
4. Cut Tiles as Needed: Use a tile cutter or grinder to cut tiles for fitting around roof features such as chimneys, vents, and valleys. Be careful and wear protective eye gear while cutting tiles.
5. Secure Each Row: Once you complete each row, ensure each tile is secured correctly and that there is no wobbling or movement.

Step 6: Installing Ridge and Hip Tiles

1. Prepare the Ridge Line: Before installing the ridge tiles, prepare the ridge line by ensuring the battens or supports are in place and secured. Some ridge tiles will require support for the mortar bed used to set them.
2. Apply Mortar/Roof Cement: Place a bed of mortar or roof cement on the ridge where the ridge tiles will sit. Use a trowel to create an even layer. Follow mortar manufacturer’s guidance for the correct mixing ratio.
3. Position Ridge Tiles: Press each ridge tile into the mortar bed, ensuring proper alignment and overlap. Use the level to check the installation.
4. Secure Ridge Tiles: After the mortar sets, secure the ridge tiles, if necessary, according to the specific instructions for your ridge tile type and material. Some will be secured with screws while others will be held in place with mortar.
5. Install Hip Tiles (if needed): If your roof has a hip, install hip tiles by following the same process as for ridge tiles.

Step 7: Installing Valley Tiles (if needed)

1. Prepare the Valley: Install valley flashing before laying the valley tiles. The flashing is key for water protection in valley areas.
2. Cut Tiles to Fit: Cut your valley tiles carefully to match the angles of the valleys. This is crucial to proper water runoff.
3. Install the Valley Tiles: Install the cut valley tiles and secure them with fasteners or mortar, as necessary. Ensure that all tiles are watertight.

Step 8: Final Inspection and Cleanup

1. Inspect the Roof: Once all tiles are installed, conduct a thorough inspection. Check for any misaligned or loose tiles, ensure the overall appearance is consistent and neat, and that all details are properly addressed (valleys, hips, and ridge).
2. Clean the Work Area: Remove all debris and tools from the roof and surrounding area.
3. Secure Materials: Properly secure any leftover materials for later use or disposal.
4. Double Check: Walk the parameter of the roof from the ground and note any problems. If problems are noted, re-inspect that area.

Tips for Success
