The Lifespan of Residential Shingle Roofs

Many types of roofs, when done by a reputable roofing business, endure longer than 15 years; some can hold up well for 50 years or beyond, barring a catastrophic storm or a big tree that falls. It should be no surprise that less expensive shingles won’t survive as long as more expensive ones, yet the price range is wide.

The Lifespan of Shingle Roofs

Asphalt shingle roofs are designed to last 15 to 30 years. The most popular form of roofing material on the market today is asphalt shingles. Because they are inexpensive and come with warranties that can last up to 25 years, they are placed on more than 80% of new homes.

Asphalt shingles offer a durable layer of protection from UV rays, wind, and rain. They are made of asphalt covering over a substrate of either fiberglass or organic material, such as cellulose. Sunlight’s warmth softens the asphalt on the shingles, which over time helps to cement their placement and create a waterproof seal.

Both organic and fiberglass asphalt shingles have advantages and disadvantages. Although more expensive than fiberglass shingles, asphalt shingles manufactured from organic elements like cellulose are very durable. Additionally thicker and covered in more asphalt, organic asphalt shingles are more durable. The reduced weight of fiberglass shingles makes them a popular option when adding shingles over an existing roof.

When put in humid environments, asphalt shingles have the propensity to develop fungal or algae damage. If you’re considering replacing your asphalt roof and you live in a very rainy or humid area, consider purchasing specially made-algae-resistant shingles.

As a result of its resistance to decay and insects, cedar is the material of choice for wood shingles and shakes. Almost any style of the building looks excellent with wood shingles as they age to a mellow silvery gray.

Depending on the caliber of the shingles or shakes, a properly maintained wood shingle roof should last 15 to 30 years. Since shingles are a natural substance, it’s not unusual to meet a few split or warped shingles during installation or to have deformity after the shingles have been installed. These flaws may result in leaks or individual shingles popping up.


The lifespan of a roof might range from 20 years upwards, depending on the materials employed, the level of craftsmanship, and the environment. The most expensive materials are also the most durable. Any home style can be accommodated by a variety of colors and patterns.
