Tile roofs come in a variety of shapes, styles and colors, from concrete to clay. Whether you would like to reuse your tiles or replace them with new ones, this type of roofing system has the capacity to last about 30 years, after which you'll want to install new underlayment (Felt paper). The exception is if your home was built in a track home setting.
A track home setting is a neighborhood that was built by one contractor. If your home was installed in a track home setting we have seen the roof start to fail as early as 20 years. The reason being is that during construction tiles need to be loaded for the structure to settle with the roof weight. Once loaded the rafters will settle with the weight of the tiles. This is very important for General Builders because sticco or windows will crack if tiles are loaded after. While stucco windows and paint are being performed the roof is on standby until every trade is done. The underlayment is not switched out and has already had foot traffic stucco spills and UV exposure. Roofing underlayment can only be exposed for weather for 6 months before it starts to lose its life expectancy.
A tile roof system is built with metal flashing, underlayment, and tiles. Each component is important to the system and cannot be missing one of the three.
The purpose for roof flashing/metal is to divert water away from a penetration, prevent water from entering behind a chimney or keeping water within a metal channel.The underlayment protects the home from water intrusions in case of a broken tile water overload, or faulty flashing.
Tiles are meant to protect the underlayment from UV rays and limit the amount of water from getting onto the underlayment.
One of the common reasons for roof leaks is because there are broken tiles on the roof or tiles that were glued together have slid down from the sealant shrinking. It is very important that you check your roof if you are not the original owner. This can prevent costly roof leaks that can damage the interior This inspection can be done by us.
