There are so many tiles to choose from, which is best for my house?
We are often asked this question. You first of all want to choose a roof tile that goes with the style of your house. If you want a “Spanish’ look, then use a clay “S” or barrel tile for example that come in terracotta ranges and blends. If you want a contemporary look, then you can use a concrete tile which comes in different profiles, textures, colors and blends. A flat concrete tile may look good on a “Colonial” home. Clay tiles are slightly more expensive then concrete but in about 5 years when they have to be cleaned, the clay tile will look like the day you installed them and the concrete tiles will look a little dull and lifeless.
All tiles break, just don’t let anyone on the roof that isn't careful or experienced, so don’t base your decision solely on perceived tile strength. All tiles approved in Miami-Dade need to pass various strength tests. Definitely use a foam paddy adhesive as it will substantially increase the breaking point of the tile and give you more wind resistance while avoiding penetrations in the tile underlayment paper which is the waterproofing layer as water runs underneath most tiles. Using nails, screws or two point foam adhesive system will give you substantially less wind and breaking point resistance!
The only roof tiles that are designed in preventing water to run underneath them are the original two piece pan and cover barrel tiles. The bottom tile creates a channel in the shape of a 'U' and the cover then is placed on both sides, thus preventing rain water to flow under the tile. We still find homes in South Florida that have these tiles and are still performing even though the tile underlayment paper is completely deteriorated and the roof may be over 50 years old. Unfortunately, this is the most expensive tile system because it uses two pieces of tile and requires more labor and material to install. Barrel tiles are now typically only installed in high end properties where the traditional look is highly valued and the additional cost is not a factor. We can greatly increase the life of any tile roof using by a premium underlayment paper like the Weatherlock or Awaplan.
Flat tiles have the best wind resistance because they are more aerodynamic since they have the lowest profile and the adhesive is centered around the tile, click to see wind resistance chart. The use of foam adhesive greatly increases the wind resistance of all roof tiles which have to pass a minimum 175 mph test in Miami-Dade or 170 mph in Broward.
Make sure the tile is not discontinued unless you keep plenty of extra tiles or that it comes with any known problems. Although there are many problematic and defective roof tiles in the market with Miami-Dade approvals, we recommend that you choose a tile from a manufacturer that we recommend.
So in conclusion, provided that you use a quality tile underlayment that will last for many years, like the Owens Corning Weatherlock which comes with a 30 year warranty, and use a paddy foam adhesive, then choose a tile that you like which compliments the look of your property and is within your budget.

Please note that on very steep sloped roofs over 7"/12' foam adhesive may not be able to be used and their could be association restrictions as to the tiles available on your property.
