Clay Tile Roof Maintenance Guide: Tips for Rain-Prone and Humid Areas
December 29, 2023

Living in an area where rain and humidity are common place? Learn what you have to do to care for your clay tile roof.

Clay tiles are known for their durability and their resistance to fire. While it takes little to maintain clay roof tiles–one of the reasons for its enduring popularity–a clay tile roof does require some maintenance if you want to get the most out of it. 

What are Clay Tiles?

Clay tiles are roofing materials made of natural terracotta clay. The clay is molded into tiles, baked, and glazed before being installed in layers on the roof. Since the tiles are fired at very high temperatures, they become very strong. They can withstand extreme weather conditions such as strong rains, cold temperatures, and high humidity.

Using clay tiles for roofs dates back centuries. And where ancient structures stood, experts are finding clay tiles that have withstood the test of time.

Clay tiles are sustainable, have timeless appeal, and remain a popular choice. Originally available in natural terracotta hue, modern clay tiles such as those by Metalink are available in more stylish shades of gray. 

Weather Challenges

No matter how sturdy clay tiles are, the weather can still pose a challenge. Prolonged rain can cause problems if debris like dust and organic matter is on the roof and gutters. High-humidity areas may lead to algae, mold, and mildew development. Monsoon season also encourages the growth of lichen and algae. When left untreated, these can break down the surface of the clay tiles, making them weak and prone to breaking. 

Cold temperatures in areas like Baguio City can damage roofs if the clay tiles are of poor quality. The cold can make tiles brittle if they are not baked at the right temperature. This is why it is important to make sure you get your clay tiles from a trusted manufacturer.

How to Maintain Your Clay Roof

A clay tile roof actually requires low maintenance. 

Clay tile roofs naturally repel water, so they withstand heavy rain. Its polished surface means there is infrequent cleaning required. High-grade clay tiles provide excellent insulation against humidity. They protect against dampness and pests, are resistant to rot and are impervious to insect damage.

To maintain the superior qualities of your clay tile roof, make sure you follow these steps for proper maintenance:

  1. Clear the roof of debris, especially in valleys and gutters, to ensure that water flow isn’t blocked. Water collected on the roof can degrade the mortar that seals the clay tiles in place. When this happens, the tiles may get damaged and leak. 
  2. Check the integrity of flashings. Regularly check the joints of the roof where we find the flashings. The flashings have to be intact to prevent leaks.
  3. Inspect for broken tiles. Broken tiles need to be replaced promptly to prevent further damage to the roof.
  4. Employ a professional to conduct a thorough inspection and cleaning. Professionals know what to look out for and how to conduct damage control.

The Need for Professional Maintenance

Clay tile roofs do not require pressure washing, chemical treatment, or waterproof sealing. Doing these to your clay tile roof may cause more harm than good because these may degrade the integrity of the clay tile roof.

Does this mean you can clean the roof on your own? Spot cleaning of debris on the gutters may be done on your own, but it is highly recommended to get experts to conduct professional inspection and cleaning. 

Choose Premium Quality

Despite the strength and longevity of clay tile roofs, individual clay tiles can break when stepped on. It takes a professional to maneuver the span of your roof to avoid unnecessary damage during the inspection and cleaning process.

Professionals also have the proper equipment to access and clean the roof. Trying to access your roof on your own may pose a danger to your safety.  

Clay tile roofs are beautiful and timeless. To make sure that they last as long as possible, get premium quality clay tiles such as those from Metalink.
