Owning a home means constant care and attention to keep everything in good shape. While maintenance might seem never-ending, regular upkeep of your property, especially your roof, can save you significant costs in the future.
In Arizona, tile roofs are a popular choice. They offer not only visual appeal but also practical benefits like reducing heat transfer, resisting fire and frost, and lasting far longer than many other roofing options.
While tile roofs are known for their durability and aesthetic appeal, they still require proper care to maintain their longevity. The maintenance steps can vary depending on the type of tile. Here’s a comprehensive guide on How Often Should a Tile Roof Be Cleaned to stay in top condition.
Types of Tile Roofs
Tile roofing materials provide durability and weather resistance. Each type also comes with its unique benefits and characteristics.
Clay Tiles
Clay tiles are a classic choice, easily identified by their rust-coloured appearance. Found in many homes in hot, sunny regions, they can last for over a century with proper care. Their shape, like the traditional barrel or Spanish barrel style, interlocks to create a near-waterproof surface on steep roofs. Modern shapes, such as S-shaped or mission-style tiles, are also widely used.
Composite Tiles
Unlike clay, composite tiles are man-made and often crafted from recycled rubber, plastic, or a combination of materials like fibreglass or asphalt. They can mimic the look of clay or slate while being lighter and more affordable. Composite tiles offer a wide range of colours and designs, making them a versatile option. While they don’t last as long as natural materials, a well-maintained composite roof can last up to 50 years.
Slate Tiles
Slate tiles, made from natural stone, are cut into shingles that give a roof a timeless, elegant appearance. Like clay, slate roofs are highly durable, fireproof, and weather-resistant. Due to their weight, slate tiles require a reinforced roof structure for proper installation. While slate is labour-intensive and costly, its longevity—lasting 75 to 200 years—makes it an excellent investment.
Concrete Tiles
Concrete tiles are the most common roofing material in Arizona. They are durable, fire-resistant, and weatherproof. Although they naturally have a grey appearance, they can be moulded into various shapes to resemble clay or slate. Concrete tiles are heavier than composite tiles but more affordable than slate. They require regular maintenance, such as waterproofing and cleaning, to last up to 50 years. Neglecting them could lead to damage, like worn sidewalks in older neighbourhoods.
Maintaining Your Tile Roof
Tile roofs are known for their durability, but they still need regular inspections and upkeep to perform their best. An annual inspection can help catch potential issues early, saving time and money in the long run.
Key Areas to Inspect
- Flashing: Check the metal flashing around chimneys and roof valleys. Any damage or wear can allow water to seep under the tiles.
- Broken Tiles: Cracked or missing tiles expose your roof to water damage. They also lose their weatherproof coating, making them vulnerable to the elements.
- Efflorescence: Common in concrete roofs, this white, chalky residue affects the roof’s appearance. While harmless, sealing or painting the tiles can restore their look and prevent further buildup.
How to Clean a Tile Roof
Tile roofs require yearly cleaning to remove debris and prevent issues like mildew and moss growth. Because of their textured surfaces, cleaning tile roofs often takes more effort than cleaning shingle roofs.
What to Watch For
- Moss and Mildew: Excess moisture can lead to moss and mildew, which not only look unsightly but can also cause structural damage. Regular washing removes these risks.
- Debris Buildup: Leaves, pine needles, and other debris can clog drainage systems, leading to water accumulation. Clearing your roof and gutters is essential to maintain proper water flow.
Cleaning Tips
Use caution when cleaning tile roofs. High-pressure washing can damage certain tile types, so it’s important to know what your roof can handle.
