Tile roofs offer higher durability and longevity when compared to traditional asphalt shingles. However, in order to properly take advantage of the longer lifespan that is associated with tiled roofs, they need to be properly maintained. Thankfully, general maintenance of tiled roofs is fairly simple if you know what to look for.
Debris, such as tree branches and leaves, can get caught underneath overlapping tiles, which in turn can loosen them, resulting in bare patches that expose your roof to the weather. Additionally, built up leaves can provide a perfect environment for mold and fungus to grow on your roof, which can spread inside your home, presenting a serious health hazard. Additionally, debris that builds up on your roof can cause water to build up underneath the tiles, causing leaks that can be hard to locate.
You can help reduce the chance of debris from collecting on your roof by pruning back overhanging trees, which will reduce the likelihood of organic matter collecting on top of your roof. Additionally, after rain storms or when the snow begins to melt for the spring, you should climb up onto your roof and remove any visible debris from underneath or on top of your tiles. Pressure washing is an easy and effective way of removing stuck on debris.
Roofing tiles are highly durable, but can be broken due to hail or falling branches, which can leave your roof exposed to the weather. It's important to note that when you are working on a tiled roof, you should place planks over the tiles, as walking directly on them can cause them to crack.
Again, cutting back overhanging trees can help reduce the likelihood of tiles from breaking, but it's inevitable that over time, some tiles on your roof will break or crack. For small cracks, silicon sealant can be used to close the cracks up and prevent water from seeping into your roof. For badly broken tiles, simply remove the roofing tiles by prying up the roofing nails and sliding a new tile in, with adhesive applied on the back, underneath the undamaged tiles. For a single tile, the surrounding tiles will hold it in place, and nothing beyond the adhesive is needed. For multiple adjacent tiles, you will have to use roofing nails to secure them in place. Ensure that every tile that you have replaced is fastened and won't move easily.
