It is easy to assume that a tile roof is made of just tiles, but there are several components that compose the whole roof. It is important to have all these elements installed by a professional, otherwise, the rest of the roof will not be as stable.
A tile roof system should always include:
- Underlayment – While tile forms the very top layer of protection against the elements, it is critical to have an underlayment beneath it. This middle barrier works to guard the wood roof deck with a secure waterproofing solution. If this internal level of protection was not there, then the deck could still suffer water damage from moisture seeping in between the tiles.
- Battens – When tiles are installed onto a wooden roof deck, there needs to be a way to fasten them tightly. Battens and batten extenders serve an important role in gripping the tiles and connecting them to the deck. Without battens, the tiles could easily slip off and break.
- Flashings – Even with a tight underlayment over the majority of the roof, there would be several weak spots without secure flashing. For example, chimneys, vents, and skylights create vulnerable spots that need to be flashed. The joints, valleys, and hips of walls or places with plumbing lines can also be prone to water damage without flashing.
