Many homeowners think of their roofs as impenetrable barriers that keep their homes safe and secure from all sorts of damage. Roofs can withstand a great deal of wear and tear and asphalt varieties can last for 20 years or more depending on the weather conditions in your area. Once you get close to the 20 year mark or a heavy storm comes blowing through, you may start to notice some damage. Torn shingles are a common type, so keep reading to learn why the shingles rip and also how you can do the needed roof repair.
Why Do Shingles Rip?
Asphalt shingles are constructed in layers and the composition of the layers will vary based on the manufacturer, type, and quality of the shingles you choose. However, every shingle will be constructed with a base. Bases are lightweight to keep the overall stress on the roof minimal. Materials like fiberglass felt, wood fiber, and recycled paper waste are used to create the shingles. All of these materials are porous ones that can readily absorb petroleum-based asphalt materials that provide the shingles with their waterproof qualities.
The porous, lightweight, and thin nature of the shingles means that they can wear down and build holes, openings, and other weaknesses. These weaknesses can then result in tears.
You should understand that significant amounts of stress on your roof from weather related incidents like balls or hail and flying tree branches can cause tears. You will see isolated damage when this happens. Tears are also a sign of aging, especially if you see the damage over a larger area of the roof. Tearing can also be a sign of water damage where the base materials are able to absorb water, expand, and tear away.
What Can Be Done?
Shingle ripping must be repaired based on the type of damage. Water damage and old age issues will often result in a replacement. However, a partial replacement can often be arranged and you may also be able to invest in a "shingle over" job where new roofing materials are placed over the older ones.
If the damage is isolated, then pinpointed repairs can be made. Some shingles can be "glued" back together if the damage is small. Use roofing cement or flashing adhesive for this. Just make sure that you press the shingle down to the roof deck to secure it and use a large amount of adhesive as well.
If rips are long, then it is best to replace the entire shingle. You can complete a replacement in a few separate ways. Since most shingles are three-tab varieties, you can replace the entire three-tab shingle. You also have the option of cutting one of the tabs away from a new shingle and replacing just the damaged tab.
Hi, welcome to my blog. My name is Wendy, and after traveling through many parts of the world as I worked on a degree in anthropology with a minor in architecture, I learned a lot. I saw how people took different approaches to the same issue (putting a roof on their home), but more importantly, I noticed how those approaches were dictated by the climate and culture in the area. Unfortunately, I think a lot of people in North America build roofs that are traditional rather than roofs that are the right fit for the climate. If you are interested in exploring the latter idea, I'm here to help. These posts look at the best way to get a roof that protects you from the elements. Explore, enjoy and send your friends over to my blog. Thanks!
