San Antonio Roofing: Article About Shingles
When it comes time to put a replacement roof on the house, homeowners are faced with many choices of asphalt shingles. Local San Antonio roofing companies offer a wide variety of shingle styles, including square tab shingles, random tab shingles and three tab shingles. Of these different options, three tab shingles are the most affordable style. Understanding the pros and cons of these shingles can help any homeowner know what to expect from their roofing system.
Three tab shingles measure three feet wide, with each shingle being equal in size and exposure. This results in a smooth surface and finished look. There is a wide range of colors for these shingles, ranging from light brown to red, green, gray, blue and traditional black.
These shingles are easy to install and most roofing jobs can be completed in just one day, not including the tear off process. If one or a few shingles becomes broken, curled or cracked, they can be replaced quickly. Small repairs of three tab shingles are often easy enough that a handy homeowner with a few basic tools can apply them, helping to save money on repair costs and lower the overall lifetime cost of the roofing system.
While there are many good reasons to choose these shingles, there are a few drawbacks too.

Their style is plain and does not make a house stand out from others in the neighborhood. These asphalt shingles are also prone to the growth of algae and moss, which can detract from the roof's appearance and lower the home's curb appeal. The shingles may easily blow off in strong winds. Hailstones can dent or crack the shingles, potentially resulting in the need for an entire roof replacement. In cold temperatures, the shingles may become brittle and crack under the pressure of a person's weight. Loss of the upper layer of granules can cause premature failure of the shingles.
This kind of roofing material has the shortest lifespan of all exterior roofing systems. Even shingles rated for 20 years may only last for 15. As a result, homeowners may find themselves having to replace the roof more than once while living in the same home.
In some communities, homeowners associations do not allow for the installation of three tab shingles. This may be for aesthetic reasons or due to municipal codes related to building requirements in wind or storm prone areas. Before choosing this kind of a roof, the homeowner and contractor should ensure that it is an acceptable material.
