roofing material

The right roofing material can help your castle stand for centuries.

The roofing materials you choose have a major impact on how long your roof lasts.

Here’s a comparison of some common roofing materials and their effect on the longevity of your roof.

Composite asphalt shingles

Asphalt shingles are the most common roofing materials, and among the least expensive. But there are different grades of these materials that can have a big impact.

Composite asphalt shingles can be expected to last 15 to 40 years, depending on the quality of the materials chosen. Some shingle roofs may even last as long as 50 years. Most shingle roofing manufactures offer a range of products in different weights and different life expectancies. Manufacturers like Owens Corning, GAF, or Certainteed come with accordingly high-end warranties pushing a half-century,” according to The Spruce.

Tile roofs

Clay and tile roofs can be both beautiful and long lasting, though they are more costly than asphalt shingles.
According to Bob Vila, “In addition to their intrinsic beauty, tile roofs are extremely durable, lasting for centuries in some cases.  Whether made of clay or concrete (the latter is more colorfast), individual tiles are often molded in barrel shapes for interlocking installation. Weight will be an issue, so be sure ask a structural engineer if your roof framing will support a tile application.”

Slate roofs

Slate is the most durable of roofing materials, and can last the lifetime of a structure if properly maintained.

Slate is another version of a stone roof, but rather than being made from molded clays or concrete, these are roofs covered with actual stone hewn from rock mined from quarries. Slate has a natural tendency to split into flat slabs, making this the ideal natural stone to cover roofs. Slate must be installed by trained craftsmen. It is the most expensive of common roofing materials, but also the most durable of all. Properly maintained, it can potentially last the lifetime of your home—even if that lifetime is two centuries long. Because of the expense, this is a roofing material usually used on large, luxury homes,” according to The Spruce.
