Tile Roof Leaks

Reaching the end of September tells me that the rainy season is fast approaching and soon there will be roofs leaking and the phone calls will start to come. I can't say that I don't  look forward to this because it creates business. But the fact is that probably 90 percent of those roof leaks will be from tile roofs. And for the most part those roof leaks could have been prevented. Some of the things that you tile roof owners should be aware of is that your roof is vulnerable to the obstacles and elements of the envirement. One thing in particular is tree debris and its accumulation on certain areas of the roof. Those areas include valleys, chimneys, walls, and skylights, not to mention any areas on the roof that are close to the tree or below it. Decaying leaves are especially detrimental to the 30 # felt under lament as the acid it creates will prematurely destroy the felt and this will cause water to get into the attic. This usually occurs in the valleys but obviously can happen anywhere there are leaves accumulating on the roof. Using a blower helps to prevent the surface leaves problem but if these leaves haven't been cleaned out for say three to four years or more then those leaves have decayed enough to create your average compost pile. Along with the leaves dirt will wash down into the valleys and other before mentioned places as well. Then the water will pack this sludge back underneath the tiles next to say the valleys where a torrent of water flows in heavy rains, and beyond channeling most of the water onto the felt under the tiles. That is when we must take the tiles out of the valleys approximately two feet on either side and clean out all of this build up of sediment and debris along with animal droppings, initial construction debris, and whatever else that may exist there. In many cases we replace the felt paper that was damaged with new felt. Also we recommend replacing the old plain valley metal with a 3 crown or 5 crown type valley. This slows the process of debris build up by restricting the water from flowing over the flat surface of the old valley style and intoduces these ribs to stop that process. There isn't much you can do to eliminate the leaves and dust clogging up your valleys and other vulnerable areas other than some preventive maintenance or ctting the tree back or even eliminating the tree. Depending on the amount of tree debris that builds up, I would think of doing the surface maintenance every year when you get your gutters cleaned. For the roof to be deep cleaned by a roofing contractor who would  do an evaluation of the extent of the roof cleaning and then give you a free estimate, should be done every four to five years. By doing roof maintenance every year you can help to extend the time between deep cleanings but you should do a deep cleaning as needed bacause we can't get these areas cleaned out properly without removing the tiles at least every five to ten years. If you are having doubts about what to do, then have your roof looked at by a licensed roofing contractor who is fully insured. Have him show you some pictures of the problem areas and that should be enough to see what is going on.
