For decades flat roofs in Texas have been posing problems for home and building owners. Harsh climate, outdated roofing technology, and very often – standing water, are the major factors affecting the lifetime and performance of flat roofs. The majority of these flat roofs were not ‘designed’ to withstand leaks or to be properly repaired. The best you could do to repair a flat roof was to pour some tar on the leaky spot. In fact, tar was pretty much the only feasible option. Unfortunately, after a short period of time, you had to fix it again, as tar would dry up, crack and let the water in. New leaks would form elsewhere. As you see – it is a constant repair cycle until a new leak begins and more money is spent.
Why Repairing a Flat Roof is a BAD Option.
When your roof starts leaking, repair is the first option that comes to mind. In this situation, you begin to think about the costs of repair, and ways to minimize them. Depending on the severity of the leak, this cost may be just a few hundred dollars, or a few thousand dollars. Here is why: when you begin to see a stained ceiling in your rooms, it is the last stage of the leak. It means that your roof has been leaking for some time now and finally, after the last heavy rain, it showed up on that ceiling. It also means that the water had to completely soak the insulation, roof deck and rafters before you could see it on the ceiling. Therefore, if you choose the cheapest and most common solution, which is patching the flat roof, you will leave behind the moisture trapped under your roof. This will cause the rotting of your deck and rafters, since there is no way for that water to escape.
Such repairs are a perfect example of sunk costs which cannot be recovered, and the fix lasts only a short period of time. After a series of these repairs, the owner gets sick and tired of it, and gets a ‘new’ roof. The building owner may get a different type of a flat roof, which unfortunately would have the same inherited problems as the old one, but would carry a different name and would be made of different materials. This seems like a very sad situation for somebody with such a roof – doesn’t it?
