High quality roofing tiles are durable, and the majority of will last over a century. It is rare to have issues with anything on a large scale unless the roofing tiles were set up improperly or the tiles are of low quality. And, while you will invest more at first on a tile roof, over time they can be very affordable.
Moss and algae will not eat through a tile roofing system very rapidly, definitely not as easily as with a wood shake roof. And the majority of the time, tile roofing repair work is not as immediate in nature as it is for other products. Due to the fact that tile roofs are pricey to install, it is much better to repair the tiles than change the roofing.
The most common two problems with tile roofs are cracked or broken tiles and debris buildup.
Just like all roofing system maintenance, keep overhanging trees cut down to decrease shade and debris. This will slow the advancement of moss and algae and minimize buildup of debris. To prevent moss growth you can fit a copper wire web to the ridge line. Water running over the copper will decrease the quantity of moss that grows below it. (If you collect rainwater for drinking, do not use this technique.).
Build up of moss and particles in the slots between the tiles can cause water to back up under the tiles. When this occurs, it can be difficult to determine the source of a leak . Tiles hang on long strips of wood that run horizontally, so water that gets behind the tiles can follow the boards and trigger a leakage in another location. Valley sections of the roofing system are particularly susceptible to this problem, and should be cleaned up every year.
Pressure washing is the most safe and efficient method to clean moss and algae, and is advised by the Tile Roofing Institute.
Fixing and Replacing Broken Tiles.
Tiles can break or end up being damaged by severe weather such as high winds or big hail, inappropriate installation or from being strolled on. When working on the roof, work on planks or a roof ladder. If you stroll directly on the tiles, they will break.
If your roofing system starts shedding intact tiles for no evident reason, it could be that the installer utilized low-cost galvanized nails instead of copper or stainless-steel. In this case, communicating all the tiles with the correct nails is the only solution.
Some tiles can be repaired with silicon sealant or adhesive.
To change a tile, pry up the tile simply above the broken one.Break the broken tile into smaller sized pieces and thoroughly eliminate them. Pry out nails. Spread a percentage of roof cement along the underside of the replacement and slide it into place. For a single tile replacement, simply the adhesive will suffice. Press all tiles down snugly.
Matching tile on an older roof can be difficult. Roofing tile providers that bring a large inventory of restored roofing tile can be your best choice. If you can not find a match, you can take tiles from a less visible part of the roofing system and fill that area with the closest match you find. Use the matching tile on the more noticeable locations. You can also have actually custom-made tiles made, but this is expensive and getting a specific match is not ensured.
Repairing Metal Flashing.
If you have metal flashing that require repair, typically you can raise the tiles simply around the flashing, change them and return the tiles. You might also find and change broken tiles at this time. Whether you do the work yourself or work with a roofer , care is required when working on a tile roofing or you will cause more damage than you repair.
