Composite vs. Slate Roofs

One of the most frequently asked questions here at Guardian Roofs is, “should I go with a composite or slate roof?” There are many pros and cons to each roof material, and we’re always happy to discuss them with our customers so they can make wise, well-informed decisions. But before we get into the advantages and disadvantages of composite and slate roof materials, let’s get some helpful definitions squared away first.

What is composite roofing?

Composite roofing is usually called asphalt shingles. It’s the most commonly used roof material in houses throughout the US. These composite roof shingles are made of cellulose or fiberglass that’s been coated with asphalt and granules. Asphalt shingles are low cost, easy to install, and come in a wide range of colors and styles to suit each homeowner’s preferences. Because asphalt shingles are relatively light, just about any home can support the weight of asphalt shingles without a need for modification. However, asphalt shingles can blow off in high winds, and they can become susceptible to mold and fungus over time. Asphalt roofs last for about 20 years before they need to be replaced.

What is slate roofing?

Slate roofs require much more of an investment because they require more expensive materials and labor, but they also last longer (more than 100 years). Some manufacturers offer a 100 year warranty on their slate roofing systems. Many people prefer the natural aesthetic beauty of slate roofing, which comes in a wide range of colors and textures. Slate tiles are shaped by hand and can be custom made in a variety of thicknesses and sizes to give your home unique curb appeal that’ll last a lifetime. Slate is completely non-combustible so in the event of a fire, your home will be protected, and it will never be affected by fungus or mold. Slate is virtually maintenance-free, so it’s a great option for homeowners who plan on living in their home for many decades to come and would prefer not to have to deal with roof maintenance and repairs on a regular basis.

There are some drawbacks to slate roofs. Slate tiles are extremely heavy, so many homes need to be modified to sustain their additional weight. Slate is also an extremely difficult material to install, so it’s essential that you find a roof contractor who knows what they’re doing to avoid major problems down the line.
