How Long Do Roofing Shingles Last?
If you ask most roofing contractors how long do roofing shingles last, the typical answer is going to be that the average is between 15 and 20 years. Asphalt shingles are not only the traditional choice, they are the most common. The reason for this is that they are generally inexpensive and relatively easy to install compared to other options. Moreover, they do come in a number of styles and colors, allowing homeowners the ability to have a more personalized look.
Regardless, the statement about the average lifespan of roofing shingles does little to inform you how long your roof will last. Ultimately, there are several factors. First, is the material. While 20-year shingles are very common, there are premium brands available rated up to 50 years. This is all based on the actual martial within the shingle. It is always best to check the warranty because not all 50-year shingles come with the same guarantees.
The other big factor is climate. For instance, in many parts of Texas, a 20-year shingle is likely to last only 14-15 years. However, the same asphalt shingles used in Pennsylvania will probably survive the full 20 years. How much heat exposure the shingles receive during the day, and the overall amount of ventilation is vital to the life span of roofing shingles. Moreover, that does not factor the effects of extreme weather events such a hail, high winds, and other conditions.
Consequently, it is a good idea to inspect your roof annually and after major weather events for signs of damage or failure. Things you should look for are curled shingles, missing or cracked pieces, and buckling. Also, inspect your gutters for granules, debris, separation of the gutter from the home or roof, etc.. That can be a sign that the protective covering is declining.
Finally, make sure you closely examine the inside for leaks or water damage. If you discover something worrisome, contact a professional to evaluate the problem.
