Wind is one of the most common types of damage found on asphalt shingle roofs even though they start at a 60 mph manufacture limited wind warranty. One of the issues that are commonly not addressed is that over the life of a shingle, they become more brittle every day with age, leaving them endlessly becoming more susceptible to wind damage. It would not be surprising to see a 20 year old three tab shingle receive damage from 50 mph wind gusts.

Keep in mind that strong winds can appear without a thunderstorm or tornado. A windy day can cause debris such as trash, lawn ornaments and patio furniture to take flight, hit your roof, and puncture it. You also need to consider tree damage. Tree branches could fall onto your roof and cause damage; so make sure to trim any branches above your home or business.

Signs of Wind Damage

If there has been a severe storm in San Antonio or your area, and you suspect something is wrong with your roof, be sure to contact Kresta Roofing. Signs of wind damage to look for are:

There are other reasons for this such as climate, ventilation, and installation. The warmer the roof gets through the year, the faster it will begin to weaken. The same goes with a lack of ventilation. If a roof is improperly ventilated, the attic will be much warmer – essentially cooking the shingles from both the bottom and the top. The installation is one of the most essential parts of the roofing process. If shingles are not nailed properly, you will be left with a variety of problems. An over driven nail from the compressor, having too much pressure, will leave the shingles susceptible to wind damage because the shingle would then be unsecured.

A perfect example of this is when it appears that sections of the shingles are sliding down the roof because there is nothing securing the shingles down to the decking. An under driven nail will leave the shingle sticking up due to the nail head being raised. This allows for wind and small debris to blow underneath the shingle and eventually it will fly off with a decent amount of wind pressure. To prevent this, we hold our crews accountable and have a project leader on every job site to check for quality.
