How Your Building And Roofing Design Can Affect Shingle Durability

Roofing shingles don't have an excellent reputation as far as roof durability is concerned, but in some cases, it is the things people do that deteriorate their roofs fast. For example, the design of a home or roof can affect the durability of the shingles on the roof. Here are some of the ways in which this can happen.

The Slope of the Roof

Although asphalt shingles can be installed on a variety of roof slopes, they deteriorate faster on some roofs than others. Specifically, installing shingles on low slopes or flat roofs presents a number of challenges that interfere with the roof's durability. This is because it's easy for water to get trapped under the shingles on flat or extremely slow roofs, which leads to roof water leaks after a few years.

Rood Design Complexity

The roof's design also plays a role in shingle durability. Here are some of the roof design issues that may accelerate the rate of wear and tear of your shingles:

  • Design elements that make under-venting difficult leads to overheating and the associated deterioration
  • Obstructions, such as chimneys or other roof installations, which prevent the free flow of water and increases the risk of water damage
  • Any design issue that doesn't create an efficient drainage system, such as poor gutter design, increases the risk of water damage

Sunlight Exposure

Roofing shingles are manufactured with coatings and granules that minimize the extent of the damage they can experience as a result of sunlight exposure. However, these protective measures aren't perfect, and exposing your shingles to too much sunlight accelerates their deterioration. 

The effect is there because the heat from the sun can dry up the shingles, and dry shingles easily curl and crack because they lose their malleability. Therefore, if the roof's orientation places most of its surface area in the direct reception of sunlight, it will deteriorate faster than it would have under a different orientation.  

The Quality of Ventilation

Lastly, the quality of the ventilation system in the house will also affect the durability of the roofing shingles. When the space below the roof (attic or under roof) is poorly vented or under vented, it heats up too much (remember, hot air rises) and affects the roofing materials above it. As previously mentioned, high temperatures accelerate shingle deterioration, so your roof's durability will be compromised.

Hopefully, you will have this information before installing your shingle roof. If you have already installed the roof, however, ensure you take good care of it to prolong its life. For more information, contact a company like Drey Roofing.
