11 Step-by-step Guidelines on How to Restore Clay Tiles

Step 1: Prep Work

Before you begin any restoration work, make sure to take the necessary safety precautions. Wear protective gear and ensure proper footing on the roof. If using a pressure washer, be mindful of delicate areas and use a low-pressure setting to avoid damaging the tiles. You may also want to cover any nearby plants or landscaping with plastic sheeting for added protection from chemicals. 

Step 2: Inspect the Roof

Thoroughly inspect the roof to identify any areas of concern such as cracked, broken or missing tiles. Take note of these locations and plan for repairs as needed. You may also want to take photos for before and after comparison. It’s also a good idea to check for any potential leak areas and address them before moving forward with the restoration process. You don’t want to seal in any existing or potential damage.

Step 3: Clean Debris

Remove any debris from the roof, including leaves, branches, and any other loose debris. Use a broom or leaf blower to clear the roof’s surface. You want a clean, dry surface to work with. It’s essential to remove any organic material that can trap moisture and promote mold or algae growth. The cleaner the roof, the better your restoration results will be. You may also want to clean out gutters and downspouts while you’re at it.

Step 4: Apply Detergent or Tile Cleaner

Mix mild detergent or specialized tile cleaner with water according to the manufacturer’s instructions. Using a soft bristle brush, apply the cleaning solution to the roof’s surface, working in one direction. This will help avoid streaking or missed spots. Avoid using harsh chemicals as they can damage the tiles and surrounding areas. If mold or algae are present, you may need to use a bleach solution (1-part bleach to 3-parts water) on stubborn stains.

Step 5: Let it Soak

Allow the cleaning solution to soak for a few minutes before rinsing it off. This will give it time to penetrate and loosen any dirt or grime buildup. It’s essential to follow the manufacturer’s instructions and not let the solution dry on the tiles as it may cause damage. The longer you let it soak, the easier it will be to remove dirt and stains.

Step 6: Pressure Wash

Using a low-pressure setting, thoroughly rinse off the cleaning solution from the roof. Start at one end and work your way across in a sweeping motion. Avoid using high pressure as it can damage the tiles and surrounding areas. Make sure to rinse off all soap residue to avoid streaking or discoloration. Otherwise, your roof may end up looking worse than before.

Step 7: Address Stubborn Stains

If any stubborn stains remain, you may need to repeat steps 4-6 or use a specialized stain remover for clay tiles. Be careful not to use abrasive materials that can scratch and damage the tiles’ surface. You may also want to test any cleaning products on a small, inconspicuous area first before using them on the entire roof.

Step 8: Check for Efflorescence

Efflorescence is the white powder that sometimes appears on clay tile roofs. It is caused by the natural salts in the tiles, and while it doesn’t harm the roof’s integrity, it can be unsightly. To remove efflorescence, use a mixture of equal parts water and vinegar and gently scrub with a soft bristle brush. Rinse thoroughly. It may take a few attempts to remove all of the efflorescence.

Step 9: Repair or Replace Damaged Tiles

Once the roof is cleaned and free of any stains, it’s time to address any damaged tiles. Use roofing sealant or a specialized patching compound to repair small cracks or chips. For larger areas, you may need to replace the tile entirely. It’s essential to make these repairs before moving on to the next step. You want a sound, solid roof to work with.

Step 10: Seal and Protect

After cleaning, repairing, and replacing any damaged tiles, it’s time to seal and protect the roof. You can use a roofing sealant or protective coating specifically designed for clay tiles. Follow the manufacturer’s instructions and apply evenly with a brush or roller. This will help prevent water infiltration, mold growth, and further damage from UV rays. The sealant will also enhance the roof’s appearance, giving it a fresh and rejuvenated look.

Step 11: Regular Maintenance

To keep your restored clay tile roof looking its best, regular maintenance is crucial. This includes keeping it free of debris, regularly inspecting for any damage or potential issues, and periodically reapplying sealant or protective coating as needed. With proper care, your restored clay tile roof can last for decades to come.

Following these 11 steps on how to restore clay tiles will help you restore your clay tile roof to its former glory, enhancing the overall appearance of your home and protecting it from potential damage. Remember to always take proper safety precautions, use gentle cleaning methods, and regularly maintain your roof for long-lasting results. With a little effort and care, your clay tile roof can retain its beautiful vintage charm for years to come.
