a beautiful slate roof on a house with towers If you are looking for a “lifetime” roofing system that can provide superior durability and add a distinctive touch of timeless beauty to your home, then consider investing in a natural slate roof.

For centuries, slate has been highly acclaimed for its natural beauty and remarkable longevity, unmatched by other materials. Investing in a slate roofing system is a major financial commitment. Therefore, it is critical to learn about advantages and drawbacks of slate before you make a buying decision.

Cost Details

One of the factors that deters many homeowners from installing a slate roof is the high cost of materials and labor. Depending on the grade, thickness, and the overall quality of slate tiles, expect to pay between $6.50 and $15.00 per square foot for materials alone.

With the installation, your total cost will be between $12.50 and $25.00 per square foot installed. The reason for such a wide pricing range is that installation/labor costs can vary widely from installer to installer. Your location and difficulty of the roof will also play a major role in determining the overall cost of the project.

How Long Does a Roof Last? Top Signs You Need a New Roof

If you are in the process of buying a new home, you probably want to know the age of the roof and how much longer it will last. Similarly, if you’ve lived in your home for a while, you are probably also wondering about the current condition of the roof and whether it’s time to consider some viable replacement options.

Curled-up shingles

This guide outlines the expected lifespans of most popular roofing systems for homes. Print it out and use it to assess the life expectancy of any roof when buying a new home or planning for future roof replacement needs in your own home.

Right Off the Bat: A typical asphalt shingle roof will last anywhere from 15 to 25 years before requiring replacement.

That said, there are several different kinds of asphalt shingles, as well as other roofing materials to consider when estimating longevity of a particular roofing system. Let’s get started.

1. Asphalt Shingles

3 tab shingle is the most basic and least costly asphalt shingle option for slopped roofs. A typical 3-tab asphalt shingle roof will last anywhere from 10 to 20 years.

Cracks or thermal splitting in asphalt shingles

3-tab shingles are an OK option for temperate climates, but they are not at all suitable for storm-prone areas. The maximum wind-uplift a 3-tab shingle roof can withstand is 60 MPH to 70 MPH.

Note: When exposed to strong, direct sunlight and rapid temperature changes (thermal shocks) commonly associated with southern states and dessert climate zones (think Texas, Arizona, Oklahoma, Nevada, and parts of California dessert), asphalt shingles can develop cracks, resulting in a greatly diminished lifespan and premature failure.

Architectural aka Dimensional Shingles are thicker and hence more durable and longer lasting than their entry-level counterparts, three tab shingles. Most architectural shingle roofs will last anywhere from 15 to 25 years, depending on their environment.

Maximum wind uplift for most architectural shingle products is 110 MPH. With a special installation method and roof-frame bracing, the wind uplift rating can be increased to 130 MPH.

Premium Shingles are normally fancier-looking asphalt shingles designed for premium homes. A premium shingle is normally thicker and will last longer than a mid-range architectural shingle. Expected lifespan of a premium shingle roof is anywhere from 20 to 30 years, depending on the environment.

Wind uplift ratings for premium shingles are similar to architectural shingles. Premium shingles can also include special properties such as enhanced solar reflectance aka CoolRoof rating and impact resistance for hail prone areas.

Tell-Tale Signs to Consider Replacement: If the asphalt shingles on your roof have developed major cracks, lost a lot of sand granules, are chipping and look dried-up or curled up, then you know it’s time for a new roof.

If the shingles are still in a seemingly good shape, but the roof has sustained significant storm or hail damage, then it’s probably time to consider replacement or partial replacement.
