It seems no matter where you reside, yr we have all seen a colder, wetter, and longer winter than in the last. How has your roof delayed? Wind, rain, ice, and snow all have an effect onto the performance of roofing materials, and their interaction with the roofing structure. In this short (part one of a 2 part series) we will discuss common types of roofing materials, their strengths, and weaknesses.
Regionally, roofing materials tend to take on historic architectural tradition. However, the necessity of modern Building and Manufacturing Codes has many traditional architectural themes giving way to hybrid designs. Today's roofing materials are made to accommodate consumer safety, and environmentally friendly requirements foremost.
In the Western, and South Western portions of the country, ceramic, and cement based tiles are most common. Originally introduced by European settlers as ceramic (terracotta) these types of roofing tiles are extremely long lasting to extreme weather exposure, and fireproof by design.
Ceramic roofing tiles are 'lap' set, one upon another atop pitched attics. The greater the pitch of the roof, the more productive the 'run-off' water will be. Generally inexpensive to manufacture, and easy to install, the primary downside of ceramic, or cement roofing tile is how much they weigh. The sub structure needed to compliment ceramic and cement tile roofing systems is far more enhanced than perhaps wooden shingle, or asphalt shingle roofing systems. Roofing joists, sheathing, and under layments are all upgraded significantly to be able to support ceramic tile roofs, and building costs are increased accordingly.
Ceramic and cement roofing tile are affixed to the roof sheathing with usually the nails in a corner end of the tile. These attachment points (nails entering the roof sheathing) are the most vulnerable for leaking. With 'lap' installation, the attachment points are always covered over by the next tile in series, and therefore are safe.
Where there is often a lifting of the roofing tiles, and exposure of the attachment points to weather, there will be problems; water will enter the sub-roof materials, and eventually into the house hold.
Typical causes for ceramic roof tiles lifting can add some freezing and growth of snow and ice under the tile, lift from significant wind, and sometimes, even rodents or birds building their nests under the tiles.
Once installed, porcelain tile roof maintenance isn't required. However if tiles need repair, adjustment or replacement, always use careful attention when walking upon them. Aside the potential of further breakage, treading on ceramic tile can cause tiles to lift, moving attachments, and creating new, unseen struggles.
