They are the most eco-friendly roofing material known by mankind; they provide excellent rain, wind and heat protection. The only thing about them is that they are very fragile and can be damaged by any impact.
Spaniards brought ceramic tile roofing tradition to Mexico and all their colonies in the New World and it spread widely across the southern part of the US. Some of their buildings stand till our times and quite a plenty is constructed yearly by construction companies across the US. Those houses look extremely classy and outstanding with ceramic roof tiles and they will look that way for next several hundreds of years.
Types Of Ceramic Roof Tiles

- flat tiles widely used in Germany,
- imbrex and tegula tiles of Ancient Roman origin,
- Roman tiles as a more modern type,
- Mission or barrel tiles,
- S-shaped pantiles and others.

Tiles usually have holes for nails, special peg fasteners or wires. They are nailed to parallel rows of wooden bars. Construction starts from the lowest part of the roof up to the top. Each next row overlaps the previous one for about 30% of the surface. This allows rainwater to flow downwards without leaking between tiles and allows hiding nail heads from water to avoid corrosion.

Clay Tile Roof Installation Requirements
Clay tiles are usually 7″ x 13″ and 1/4″ to 1/2″ in thickness. Wet clay is put into forms, shaping it as future tiles and then heated in a kiln for up to 2000degF to vitrify. It becomes smooth, hard, waterproof – but not too durable. So it is best not to drop or smash it. Natural color of unglazed clay tiles is terracotta, but it can be glazed in different colors to make your roof a masterpiece of architecture and design.
To place them your roofing should have a slope of at least 1″ per 4″ to allow water drainage. Each tile is placed above the previous one and covers from 10 to 30 percent of its surface. They have holes for nails, wires or fasteners to hold them in position. If supporting battens are placed horizontally, gaps should be left in them for water drainage.
Tiles can be placed in three possible ways – vertically, horizontally, or in a cone. If you live in a sunny and hot but not too windy or rainy area, the wisest for you would be to place them horizontally. For excessive rainy and windy areas vertical placement is the best. If you have round or conic roof, you will position tiles in a cone.
If you live in an area with regular heat and cold changes, your roof should comply with ASTM C1167 Grade 1, which allows the ability of minimal water absorption. Grade II should provide medium resistance to freezing, and Grade III is porous and can be used only in southern areas without extremely snowy cold seasons like Florida, Arizona, Texas, California or New Mexico.
Those clay tiles are heavy. Your roofing should be really stable and durable to hold them. Check it twice to avoid them breaking your roof and caving in.
- You should realize that clay is not as durable as steel plates, slates or corrugated plastic. They are best to be placed above other roofing for decorative purposes. As tiles aren’t very durable, try to avoid walking on them during construction. Use a ladder instead to avoid costly repairs. Do this with your friend to help each other and make the job easier, or hire professionals if you can afford it.
- For protection from strong wind you should use tile locks or/and mortars. Ridges of the roofing are protected with special flashings that cover both neighboring tiles in order to prevent damage from strong wind or extreme snow load.
- For horizontal placement, use wooden battens and nail tiles to them in a row, starting from the lowest part of the roofing up to the top. This can be used for “S” type tiles.
- For vertical placement there are several possible ways of fixation. Spanish or mission tiles have an eave closure with a hole for water drainage, and are either nailed or secured with peg fasteners. Tapered or barrel mission style tiles are nailed to supporting battens.
- Sometimes chains are being put instead of vertical battens. Chains are anchored to the roofing, and tiles covering them are wired to the chains. This is very useful for conic roofs.
After your clay tile roof installation will be complete, your house will become outstanding and beautiful, awesome and remarkable. This roofing will last for decades without losing its beauty and efficiency. You deserve it – so why not order it?
