The Essential Dos and Don'ts of Maintaining a Concrete Tile Roof

Concrete tile roofs are well-suited to areas with harsh weather. They'll stand up to high wind and protect your home for up to 100 years if maintained properly. But just how do you go about maintaining a concrete tile roof? Here are some essential tips to keep in mind.

Do: Inspect the roof for cracked tiles.

Just because a tile roof has a life expectancy of 100 years does not mean that every individual tile will last that long. Branches falling on the roof, hail, and heavy snow can all cause individual tiles to crack. It's important to replace cracked tiles promptly, so get into the habit of scanning your roof for cracked or chipped tiles about once a month. Pay special attention after storms. If you do notice some cracked tiles, your best bet is to have them replaced by a roofing company as walking on and repairing a tile roof is a skilled endeavor.

Don't: Pressure wash the roof.

Keeping the roof clean will help prevent the tiles from breaking down prematurely. However, you don't want to use a pressure washer because it can erode the tiles or push water beneath the tiles, leading to leaks. A better strategy is to use your garden hose. Stand on a ladder and just spray the water towards the peak, letting it roll off the roof and slowly take debris along with it.

Do: Have the roof repainted when it starts to look worn.

Many concrete tile roofs are painted to enhance their appearance. But the paint is not just for good looks. It helps seal the tiles against rain and moisture. If you notice the paint starting to chip, it is time to repaint your roof. You can do this yourself by renting a paint spray gun if you're comfortable walking on the roof. Use a heavy duty acrylic paint made specifically for tile roofs, and always apply two coats, allowing the roof to dry completely in between.

Don't: Step on the edge of the tiles.

If you walk onto the roof for any reason, be very careful where you step. Avoid stepping along the edge of tiles, as this can cause them to crack. Try to distribute your weight across several tiles at once, always stepping in the middle of the tiles. Wear rubber boots or shoes, as they are less likely to crack the tiles than heavy work boots.
