In San Diego, shingle roofs are one of the most common types of roofing applications we see. A shingle roof is any roof made of asphalt shingles, also known as composition shingles. This type of roofing system is far more durable than a flat roof or tile roof system.

Asphalt shingles are a great choice because they require little maintenance, are easy to repair, and can be used on a wide variety of roofs. They are also very economical because they are relatively inexpensive for the reliable roofing system they provide.
Should I Replace My Shingle Roof?
Another type of roof we commonly see in San Diego, and the most predominant, is asphalt shingle roofing (more commonly known as composition roofing). This type of roofing system is far more durable than a flat roof or tile roof system. The most common asphalt shingle that we use here in San Diego is a dimensional 30-year or a dimensional lifetime shingle. Fixing loose or broken shingles is relatively easy, but if your roof is over 20 years old and most of the shingles are worn, you will want to look at replacing it.
But just because they are economical doesn’t mean that you have to compromise on looks. Asphalt roof shingles come in a variety of textures and colors. You can also find asphalt shingles that mimic the look of cedar shakes, wood, slate, or tile.
There are different types of asphalt shingles, from a flat looking shingle, to a shingle with profile and definition than high grade asphalt shingle with a higher definition and a more complex pattern looking almost like a shake roof system. The most common asphalt shingle that we use here in San Diego is a dimensional 30 yr or a dimensional lifetime shingle. The cost of these shingles vary by the years and longevity of the product or material.
TYPES Dimensional Shingles The most popular type of asphalt shingle is the dimensional shingle. The dimensional shingle lasts longer, is more durable in heavy winds, and is more aesthetically pleasing.
Premium or High Profile Shingles Many manufacturers offer upgraded, higher profile shingles that are even thicker than standard dimensional shingles. These upgraded shingles offer higher wind resistance, show more definition, and have a higher profile.
3-Tab Shingles About 20 to 30 years ago the 3-tab shingles were very popular. But they lay very flat and are much thinner than the dimensional shingles that are used today.
MANUFACTURERS Owens Corning and GAF are the two major manufacturers of asphalt shingles in the San Diego roofing market. Both Owens Corning and GAF provide limited lifetime warranties on all their dimensional shingles.

Here is an example of an existing roof system that has been torn off down to the plywood deck. As you can see, the plywood overall is in good shape. That is due to the underlayment which is the felt paper that protects the plywood deck from moisture intrusion. In San Diego, houses that are 25 years old or less, in most cases, have plywood as the roof deck surface. Houses that are over 25 or 30 years old could have plank boards instead of plywood. That was the standard deck surface back 25 – 30 years ago.
