For you non-Spanish speakers, I won't attempt to translate this crude term into English. But trust me- its not good (I'm Mexican-American so no offense intended)
WARRANTIES: The typical lifespan of shingles used on most residential buildings ranges between 20 and 30 years. Standard 3-tab shingles include a manufacturer's warranty of 20-25 years, while the heavier Architectural type shingles offer warranties between 30-50 years- the 30 year being the most common. However, if you've ever taken the time to fully read all the fine print within each manufacturer's written warranty, you'll notice a litany of "Exclusions" hidden within. For example, one of the largest manufacturer's official "Limited Warranty" page contains 12 specific exclusions, each of which is written broadly enough as to exclude just about any claim they deem fit. The biggest determining factor in shingle warranty claims is how closely the installer follows the manufacturer's installation guidelines- which are subject to change according to the local environmental conditions. This is why it is so important that the installer be very familiar with these guidelines as well as local conditions. If problems arise later, any deviations from either can surely trap the homeowner into one of these dreaded exclusions. However, even the best installation can't always prevent problems.
WIND DAMAGE: By far, the most common factor in shingle's premature failure is the wind. And of course, wind damage is one of the "Catch-22" exclusions found in roof material warranties. I live and work in Tucson, Arizona, which is not considered a "High Wind Zone" by national standards. But for anyone that's lived here for any length of time, we know otherwise! Local wind gusts- especially during our summer monsoon season- have been known to surpass 100mph! Not to mention the powerful micro-bursts that accompany these storms. Shingle guidelines outline specific nailing patterns in high wind zones. Yet because we aren't labeled as a "high wind zone", these guidelines are rarely followed here. That leaves the manufacturer in the clear when shingle damage occurs during these inevitable storms. Often times, the damage left behind can be relatively minor, easily repaired by a good do-it yourselfer. If that's you, I've included a link to one of the best step-by-step guides I've found to these repairs, written by Merle Henkenius:
Other times, these strong winds leave much more damage in their wake, exposing large swaths of underlayment (felt) and even wood sheathing to the elements. In these cases, it can be very critical to have repairs made as quickly as possible! Everyone knows that leaks are a certainty if wood is left exposed on a roof. What most people don't realize however, is that exposed felt covering that wood, is almost just as likely to leak. That's because the felt required beneath shingled roofs is the very minimum thickness required of any roof surface. The reason is - unlike tile and other roof surfaces - rainwater is never expected to penetrate or pass beneath shingles- in theory. In shingle applications, the underlayment's job is to prevent the wood sheathing from sucking the oils from the shingles, thus drying them out prematurely. These felts aren't meant to be watertight or exposed to the elements. Covering these areas as quickly as possible can save you thousands in additional repair costs.
QUALIFIED REPAIRMEN: Its also critical to have only a qualified, experienced technician doing your repairs. I've been to many homes where previous repairmen have used the wrong type, wrong size, wrong nailing pattern, wrong underlayment or wrong adhesive materials to make repairs.
Doing this for over 35 years has given me great insight into some of the schemes, unprofessionalism and downright ignorance of other roof "repairmen". But I've also come across some very good, qualified repairman - some of whom now work for me. I offer free and honest evaluations of your shingle roof problems. If you choose to call someone else, please make sure he's qualified in this field and not interested in selling you more than is required in your particular situation.
