A shingle roof costs between $7,500 and $24,000 in total. The exact cost depends on the size of your roof and the number of bundles of shingles required. A bundle of shingles typically costs between $40 and $60, though contractors might be able to get a lower price than you’d get buying from a local hardware store.

Architectural shingles typically last between 20 and 30 years. While some manufacturers provide warranties for 30 to 50 years, particularly for extreme weather, achieving such a long lifespan is uncommon. The actual life of your shingles can be shorter if you live in an area prone to strong winds, hailstorms, or other severe weather. To avoid the risk of roof failure and costly water damage from leaks, it is recommended to replace your roof before it reaches the end of its expected life. Scheduling regular roof inspections every few years is a good way to assess your roof's condition and determine the best timeline for replacement.

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.

Underlayment exists under your tile roof. It helps protect your home by acting as a secondary water barrier. Often, when roof tiles fall off, underlayment that's in good condition can temporarily keep water from getting into the home. However, immediate replacement of missing tiles is crucial to avoid additional roof damage.
