Tile Roof Installation

Repair and reinforce the roof (if applicable). You should have reinforced the frame of the roof earlier before stripping any existing roof off. That said, the sheathing–the layer of wood or other material that covers the area between the relatively open frame and the outer layers of roofing–may be damaged or weak. Strengthen it. Again, think about the weight involved. The fairly cheap and common shingle roofs that many people have are quite light; if you are transitioning from a light roof to a tile roof, the weight difference will be substantial. For a relatively average house with a 1,500 square foot roof, the total of underlayment and tiles will equal something approaching 8 tons in weight. That’s more than the equivalent of having two large SUVs parked on top of your house.

Installing a tile roof can be a difficult and laborious process. A project of this size will take a great deal of planning and preparation, well before the actual tile installation is underway. Whether you are laying brand new roofing tile or replacing damaged ones, it is also important to have the right technique. This article will tell you how to install roof tile.

Develop an estimate of the materials. The most important staring point comes from your roof dimensions. You can use this calculator to help you determine the size of your roof (do not use the function titled “Tile Calculator,” which is clearly intended for interior floor tile). Without specific information about the type of tile selected, it is impossible to estimate the number of tiles necessary to complete a job. A 100 square foot section of roof could require anywhere from 75 to 400 tiles.

Consider the impact of weight. To put it in simplest terms, a basic asphalt shingle (perhaps the most common roofing material in America) will typically place a weight of less than 3 pounds per square foot on a roof. Concrete tiles, which are usually lighter than clay tiles, can easily place over 10 pounds of weight per square foot on a roof. If you are adding tiles to a roof that did not previously have them, or to a design which did not originally incorporate them, the roof may not be capable of carrying the excess weight. In his case, you will need to have your roof inspected and possibly reinforced to bear the load.

Install the underlayment. Position the first roll of underlayment at one side of the roof, perpendicular to the lower edge (the eave) of the roof. As you roll out the underlay, keep the bottom edge of the material aligned with the edge of the eave but above any metal or synthetic edging that may cover the borders of the eave. Secure the underlayment. Roll out 10 foot (3 m)-long sections at a time, and then secure it with nails separated by intervals of 24 inches. Keep all nails at least 2 inches from the edge of the roof. When you reach the end of the roof, cut the underlayment roll to match the edge. Secure the end with nails. Restart at the end of the roof at which you first began. Overlap the underlayment, with the new layer partially covering that which was already applied. There may be a series of lines along the roll of underlayment, and this is intended to show the installer precisely how much the layers should overlap. Treat the top line on the installed layer as you previously had the bottom edge of the eave.

Start by placing a ladder to easily access the roof. You can create an underlay with a metal flashing which is corrosion-resistant. Over the metal strip, lay down rows of roof battens across the entire roof-spread. Leave small gaps between the rows of battens to ensure that any rainwater that seeps through, is easily drained-away. Always start laying tiles from the side of the roof.

One of the most important considerations for installing clay tile is to have a great roofing underlay. The material used below the clay tile is a critical factor that will affect the tile's durability. Normally, the underlay is made from asphalt-saturated roofing material covering all area below the tile clay cover. Ensure that it's properly attached or installed or you can end up with overlying tiles pretty quickly. Install an extra layer near the roof edge and in valleys to protect the surface even more. As a minimum, cover all decks with two layers of No. 30 asphalt-impregnated roofing felt or one layer of No. 43 coated base sheet.

Clay tiles are sold in various sizes and shades, making them suitable for all structural requirements. Clay roof tiles maintain their natural color for long periods. A good example of this is pitched roofs made of clay roof tiles that are known to survive for decades without fading. They require little maintenance except periodic cleaning. They are fireproof too. In terms of time needed to complete the roofing project, it takes more time to lay a clay-tile roof than wood/metal roofing. However, the overall weather insulation of clay roofing is superior to any other roofing alternative.

Install the ridge tiles. After you have completed the “fields”–that is, the broad surfaces of the roof–you will need to cap the tops with special ridge tiles. These are rounded, and depending upon design can either be laid out end-to-end or in an overlapping style. This should be the final step in the process of installation. Congratulations are due for your successful assembly of a new tile roof!

Install battens (if applicable). If the roof has a steep slope, battens may be required to hold the tiles in place. Battens are thin strips of material (usually wood, but sometimes metal or plastic, and commonly 1 inch thick and 2 inches wide) that run horizontally along the length of the roof. Many tile varieties possess a lip or hook that will hang on available battens. (Obviously this is one more thing to consider when identifying the tile that fits your needs) In addition, clips are available to attach the tiles onto the batten. Use two tiles to determine the spacing required for the battens. A minimum of a 3 inch overlap is required for the tiles that do not interlock (interlocking tiles will take care of the measurement for you), and a smaller amount of overhang should be left over the eaves. Factor this in as you determine the locations of the battens. After you have determined the distance between the first two battens, measure the distance and set battens using that spacing all the way up, making sure to double check measurements as you go along.

Make a list of necessary materials and tools. While some of these are common–for example, it is recommended that you have a ladder–others are rather specific to this task and are items that are likely not yet in your inventory. For example: Gasket nails are a type of nail with an interior plastic cap that will help seal nail holes and prevent leaks. Underlay or underlayment. This is the water-resistant layer between the tiles and the roof frame and sheathing. A number of varieties are available, but because this is a roof intended to last from 30 to 100 year, it is probably a good idea to invest in one of the heavy-duty options. Outdoor caulking or sealant. There are a number of caulks or sealants available for outdoor use, but once again it is recommended that you use especially durable and high quality products. This roof could last a lifetime, but it won’t if the materials don’t suit the requirements of the job.

Clay roof tiles are very popular as they create an attractive Mediterranean look. They're durable and lightweight, making them ideal for certain roofs, and they offer better insulation when compared to similar materials such as ceramic tiles. When installing clay tiles, picking the right size, color and installation method, which depends on the type of clay tile, are important factors.

Plan for a specific time. If you are going to replace the roof of an existing home, you must factor in the weather and the time you have available in which to complete this job. While it is obvious that you aren’t going to want to rip your roof on during the winter, you must also look for dry days. Check the long-term weather reports (with an understanding that forecasts do change). Also, make sure you have enough manpower available to complete this project in a timely manner. This is not a one person job, and you will have to plan accordingly.

The California-Spanish beach house gets an authentic barrel tile roof, and Bob takes a trip to the factory in Mexico where the clay tiles are manufactured. Comedian Tim Allen gets some Bob’s expert assistance in pouring a new garage floor. And back at the Malibu site, exterior stucco application is complete.

After laying the first layer, secure each tile with a nail. Hammer each nail into the center of contoured edge of the tiling that is easily identifiable. Now lay the second layer over the first layer of tiles, packing the tiles in a compact manner. The overlying tiles should form an interlocked configuration with the first layer. This interlocking doesn’t have to be created. The retailed roof tiles have the required edges to allow easy interlocking. When the tiles are interlocked, there must be no dust or debris between the tiling joints. If you find any, brush it away with a dry, painting brush.
