The purchase price of 3-tab shingles is less than that of other material varieties, such as architectural shingles. However, 3-tab shingles generally last far fewer years than even the least expensive architectural ones. Other roofing types, such as metal or clay, also cost more than 3-tab shingles. However, if you plan to stay in your home for many years, the long-term cost of any of these options can compete with 3-tabs because of their longevity.

The lifespan of a torch down roof depends on the number of layers installed. A single-ply system typically lasts between 10 and 15 years, while a multi-layer system with two or three layers can last from 15 to 25 years. Although a multi-layer option may be more expensive upfront, it provides a longer service life. Warranties often reflect this, with about 12 years for a one-ply system and 15 years for a two-ply system. For context, this lifespan is shorter than other common roofing materials like wood or asphalt shingles, which typically last 20 to 30 years, with high-quality versions lasting up to 50 years.

When installed and maintained properly, a cedar shake roof should last up to 60 years. Severe weather and high winds will damage your roof, reducing its life span. Expect a shorter life span if the roofer didn't use top-grade material, didn’t have cedar shake expertise, didn’t create the proper ventilation, or didn’t use the correct fasteners. Keeping up with maintenance will help it last longer. It’s also a good idea to get roof inspections on a regular basis to help spot repairs before they become major issues.

Properly installed chimney flashing can last anywhere from 15 to 50 years. However, flashing generally only needs to be replaced when it is damaged, corroded, or no longer creates a watertight seal. Several factors influence its longevity, including the material type, quality of installation, and local climate. For example, copper flashing tends to last longer than galvanized steel. Large storms and extreme weather can also damage flashing, potentially requiring earlier replacement. To ensure its longevity, it is recommended to have your chimney and roof inspected annually. A professional can assess the flashing's condition and recommend any necessary repairs.
