How Long Do Organic Asphalt Shingles Last?

Organic asphalt shingles have been a popular roofing material for many years, often backed by 25-30 year warranties from manufacturers. However, the actual lifespan of these shingles can vary significantly depending on several factors. Let’s explore what organic shingles are and how long they typically last.
What Are Organic Asphalt Shingles?
Organic asphalt shingles are created by using an organic mat, such as recycled felt paper, which is then saturated with asphalt to make it waterproof. The shingles are then top coated with adhesive asphalt and embedded with ceramic granules for added protection against the elements.

Factors Affecting the Lifespan of Organic Asphalt Shingles

While manufacturers often provide 25-30 year warranties on organic asphalt shingles, the actual lifespan of these shingles can be much shorter, especially in certain climates and conditions:

Climate: Extreme weather conditions, such as heavy rain, hail, sleet, snow, high winds, and high temperatures, can accelerate the deterioration of organic shingles, particularly in northern and midwestern regions of the United States and Canada.

Installation: Proper installation is crucial for the longevity of organic shingles. Poor workmanship or the use of low-quality materials can lead to leaks and other problems, shortening the shingles’ lifespan.

Maintenance: Regular maintenance and prompt repairs can help extend the life of organic asphalt shingles. Neglecting a roof can cause it to fail much sooner than expected.

Manufacturer and Quality: The quality of the shingles and the manufacturer’s reputation can also impact their lifespan. Higher-quality shingles from reputable manufacturers tend to last longer than budget options.

Signs of Organic Shingle Damage
There are several signs that indicate organic asphalt shingles may be nearing the end of their lifespan:

Pitting, granule loss, and discoloration
Cracking, blistering, or curling of the shingles
**Shingles that are especially damaged on south-facing sides, where they receive the most direct sunlight

If you notice any of these signs on your organic asphalt shingle roof, it may be time to consider a replacement. Consulting with a professional roofing contractor can help you assess the condition of your roof and determine the best course of action.
