Dangers of Water on a Tile Roof

August 7, 2015

Tile roofs can add beauty to a home! Have you ever wondered, though, what’s happening underneath your tiles? Here in the Northwest we are well acquainted with rain, and when rain water gets underneath tiles, whether from an angled downpour or a broken tile, what can happen isn’t so pretty.  Ponding occurs when water pools against the wood, causing rotting and water staining, which in turn can cause structural damage to the roof. Ponding is caused by the deterioration of the felt underlayment. This felt is put in place to direct water away from the wood, but is not made to withstand large amounts of water. Eventually, the felt gives way, allowing water access to the wood.


Thankfully ponding is preventable!  Anti-ponding boards and anti-ponding foam can be installed underneath the bottom most tiles on your roof, laying behind and against the gutters. These replace the felt, not only by directing water away from the wood, but also by providing a barrier in front of the wood. While the felt will give way over time, the anti-ponding materials are made to hold up against long term standing water. You may be asking “Why weren’t anti-ponding materials installed in the first place”. In order to cut costs, many roofers don’t use anti-ponding material when installing a new roof, but rather choose to go with the short term solution of felt. Many older roofs also don’t have anti-ponding materials due to a lack of recognition of the problem until recently, and lack of available options when they were built. Whatever the specific reasoning may be, without Anti-ponding materials, your roof may be at risk for long term damage. Here at Northwest Roof Maintenance, Inc. we want to help you avoid this risk!


How do you know if you need anti-ponding materials installed? Chances are if you are noticing water stains or rotting near the edges of your roof or behind your gutters, or you have an older tile roof, you may need Anti-Ponding.
