Southlake, TX, is prone to storms, which is why most property insurance policies provide coverage for damage caused by such inclement weather (hail damage included!). It is not uncommon here that hailstorms cause roof damage, so, yes, you should worry about it, but also take action to protect your roof.
A hail storm is hard to predict, and when it starts, there is nothing you can really do to keep your roof safe. This is why you must make sure that your Southlake roof is strong enough to withstand such weather.
Knowing the exact condition of your roof will allow you to fix the problems in time to protect your investment and your comfort.
