Roof Installation Guide – Choose, Install & Care for Ceramic Tiles

If you’re thinking about a new roof, the first question is usually “what material?” At KSR Ceramics we sell ceramic tiles that last, look good, and keep water out. Below you’ll find the basics you need to pick the right tile, lay it correctly, and keep it in shape for years.

Choosing the Right Tiles

Not every tile works on a roof. Look for glazed or unglazed ceramic that is rated for external use. The rating tells you if the tile can handle rain, wind, and temperature swings. A good rule of thumb: the higher the water‑absorption rating, the less suitable it is for a roof.

Next, match the tile profile to your roof’s shape. Flat tiles fit sloped roofs, while interlocking profiles are better for steep pitches. Ask yourself if you want a smooth look or a textured finish – both are available in our catalog.

Don’t forget the colour. Light colours reflect heat, keeping your attic cooler, while darker shades hide dirt better. Pick a shade that complements your home’s exterior and fits local building codes.

Step‑by‑Step Installation Tips

1. Prep the deck. Clean any old material, repair rotten boards, and lay down a waterproof underlayment. This layer is essential – it stops leaks even if a tile cracks.

2. Mark the starter course. Use a chalk line to draw a straight line along the eaves. This line guides the first row of tiles and ensures everything stays level.

3. Lay the first row. Spread a thin layer of mortar, press the tile down, and tap gently with a rubber mallet. Keep a consistent spacing – most ceramic tiles need a 2‑mm gap for expansion.

4. Install subsequent rows. Stagger the joints like bricks. This pattern adds strength and prevents water from finding a straight path down the roof.

5. Secure the tiles. Use roofing screws with washers or nail‑on clips designed for ceramic. Follow the manufacturer’s spacing recommendations – usually every 30‑45 cm.

6. Finish the edges. Add drip edges and flashing around valleys, chimneys, and skylights. These metal pieces direct water away from vulnerable spots.

7. Clean and seal. Brush off excess mortar and apply a breathable sealant if the tile manufacturer advises it. This step boosts water resistance without trapping moisture inside.

After the roof is up, walk the perimeter and look for any loose tiles. A quick tap with a rubber mallet should make each tile feel solid. If you hear a hollow sound, re‑fasten that tile before the mortar fully sets.

Maintenance is simple: remove debris, check for cracked tiles after storms, and replace any that show wear. Because ceramic doesn’t rust, you’ll spend far less on upkeep than with metal roofs.
