How Long Will a Roof Last?

Asphalt shingles are the most common type of roofing material. More than 80% of new homes have them installed because they are affordable and come with warranties, sometimes reaching up to 25 years. When talking cost in the roofing world, you will see things listed per square. An example would be shingles costing $100 per square. A square is 100 square feet.

Generally speaking, asphalt shingle roofs can last anywhere between 15-30 years. This depends on many factors, mainly concerning the quality of shingles used, the quality of workmanship in the install, and the weather and environmental exposures the roof will face over its lifetime.

Essentially, a shingle is made up of refined petroleum - asphalt, rock granules, and reinforced by fiberglass. The asphalt is the primary source of waterproofing for the roof. Much like the asphalt in roads, shingles will expand and contract in response to weather changes. This can cause cracking of the shingles or granule loss. This is the aging process of shingle roof.

Routine maintenance provided annually or semi-annually can help prolong the life of the roof. If you need assistance in inspecting your roof, Active Home Inspection Services is available for maintenance inspections. Contact us today.
