Clay Tile Roof Installation
Clay tile roofing is designed for roofs with a pitch greater than 20° degrees. The steeper the roofs provide a better view of the tile and can be a beautiful addition to cathedral type roofs.
The first step in installing a clay tile roof is making sure the surface is level. If the decking isn’t level adjustments are made so the clay tile roofing will lay flat and properly protect your home.

Clay Tile Roof Repair & Maintenance
Identifying The Problem
Missing, damaged tiles, or leaks into your home are obvious signs that there is something wrong with your clay tile roof. While noticing stains on the ceiling or water dripping into your home is easy enough to find, the source of that leak isn’t always as easy to track down. Thorough inspection in the attic to find the spot the water is coming in, and then exterior inspection is required to find the real source of the leak. While water might be entering at one spot, water can travel from the damaged roofing tile and enter at a different spot.
Immediate Leak Prevention
It’s important to keep water out of our attics and homes. Water that is allowed to enter and sit will end up causing mildew and mold, which can be serious health hazards. Even the structural integrity of the roof itself depends on staying dry. When damage is found Plastic material, plywood sheets, or other roofing products can be laid over the area until repairs can be completed.
Clay Tile Repair Process
When the source of the leak is identified a repair plan will be laid out with an estimate including the materials and labor costs. Repairs can range from replacing a single clay roofing tile to having to repair structural roofing members, underlayment, or the wood decking material. When gutters or flashings are the source of the leaks it is necessary to remove the tiles in that area to properly remove, resurface, and install the new flashings or gutters.
For older clay tile roofs it may even be necessary to remove entire rows of tiles to provide a path to repair the damaged, leaking area. This is due to the fragile nature of older clay tile roofing. Simply walking on them can cause tiles to break or come loose from the fastening system.
Clay Tile Roof Life Expectancy
Clay tiles are one of the longest lasting roofing systems available. Concrete tile roofing is rated to last about 50 years, in contrast clay tile roofing when properly maintained can last 100 years or more. Clay tile roofing has great impact and fire ratings and because of their durability significantly increase a home’s value.
Material & Fastening System Failures
The fastening system used to secure the clay tiles to a roof are the most common reason that clay tile roofing systems fail. Frost can damage the clay tiles themselves, yet this is very rare in the Phoenix area. Many times in older roofs the wooden pegs that are riveting the clay tiles rot with time. Even when iron nails were used they corrode due to the tannic acid present in older sheathing or oak battens. Other areas that are common problems with all roofing are gutters, valleys, and flashings.
Clay tile roofing is heavier than some other roofing materials. Because of this the support system holding up the roof can also be a source of failure. When downspouts and gutters are allowed to fill with leaves, twigs, and other debris water will eventually back up and get under roofing tiles. This will deteriorate sheathing, battens, the fastening system, and even compromise the structural integrity of the roof itself.
Initial Material Quality
Historically clay tiles were handmade; roofing that was done before the end of the 19th century fits this category. Today tiles are usually machine made. Whether clay tiles were machine or handmade quality can vary from tile to tile. If there is visible soluble salt on the surface of a tile it can be an indication that the tile was not properly fired. This means that it is excessively porous. These excessively porous tiles allow water to come in contact with the roof battens and can lead to degradation and even structural rot.
