If you are in the market to replace your roof, one of the decisions you will have to make is what type of roofing material to use. There are a variety of materials available, including asphalt shingles, clay tiles, and metal roofs. If you decide to go with clay tiles or metal roofs, you will also need to decide whether to install the tile or metal over an existing roof (known as a “retrofit”) or remove the old roof first and start from scratch (known as a “new construction”).
As you explore roofing options, you’ll see that the decisions can get overwhelming quickly. In this article, we’ll focus on one particular roofing material – tile – and provide some guidance on how it all works.
What is Tile Underlayment?
Before we dive into the cost of replacing roof tile underlayment, let’s first define what roof tile underlayment is. Roof tile underlayment is a material installed between the roof deck and the roofing tiles. Its purpose is to protect the roof deck from water damage and provide a level surface for the tiles to be installed on.
There are two types of tile underlayment – felt paper and synthetic. Felt paper is the more traditional option and is made from organic materials such as asphalt. Synthetic underlayment, on the other hand, is made from man-made materials such as polypropylene or polyethylene.
If you have a tile roof, chances are you have a felt paper underlayment. This type of underlayment is installed in layers and each layer overlaps the previous one. The number of layers will depend on the climate and location of your home. For example, homes in hurricane-prone areas will have more layers of felt paper than homes in other areas.
Normally, felt paper is installed with nails or staples and then covered with a layer of roofing cement. This provides a barrier between the roofing materials and the underlayment.
Replacing Tile Underlayment
So, how often does a tile roof need to be replaced? The answer depends on many factors, including the type of tile, the climate, and how well the roof was installed and maintained. Clay and concrete tiles can last for decades, but they are more susceptible to damage from hail and high winds. On the other hand, asphalt shingles have a shorter lifespan, typically lasting between 15 and 30 years.
If you live in an area with severe weather conditions, you may need to replace your tile roof more often. For example, if you live in an area that is prone to hurricanes, it is important to inspect your roof after each storm to check for damage. If you find any damaged tiles, it is important to replace them as soon as possible to prevent further damage.
How much does it cost to replace roof tile underlayment? The cost of replacing roof tile underlayment varies depending on the type of tile you have, the size of your roof, and the severity of the damage. If you have a small roof, you may be able to replace the underlayment yourself. However, if you have a large roof or if the damage is severe, you may need to hire a professional to do the job.
In truth, the best option is to contact a professional regardless so that they can analyze the condition of your roof and give you an accurate estimate of the cost to replace roof tile underlayment. If you have any questions about replacing roof tile underlayment, please ask an expert!
