The Pros and Cons of Slate Roofing

Every type of roofing has pros and cons. We’re here to help you know exactly what to expect.


Pros of Synthetic Slate Roofing

  • Affordability: Synthetic slate shingles offer the beauty of a natural slate roof, but at a fraction of the cost.
  • Style Variety: You can find a wide variety of shapes, colors, and sizes to create the perfect slate roof design that matches your architectural style.
  • Eco-friendly: Many of the materials that go into a synthetic slate roofing shingle are recycled. Slate shingles are also highly durable and can last up to 50 years, making them superior to many other roofing options. We also offer cedar roofing which is also 100% biodegradable

Cons of Synthetic Slate Roofing

  • Not all are created equal: Some synthetic products in the market are not up to standard when it comes to fire-ratings. That is why it is crucial to find a local Vienna roofing company like Certified Inc. Roofing who has the experience and training of which materials are the best quality in the industry.

Slate Roof FAQs


What is the cost of installing a slate roof in Northern Virginia?

This will ultimately depend on the size of your home and the style you choose. Typically, you can expect your synthetic slate roof to cost $10,000 to $16,000 per 3,000 square feet in Northern Virginia?

What is composite/slate roofing?

Synthetic slate shingles are made from plastic and rubber. These materials are injection-molded to create an authentic-looking shingle at a fraction of the cost of natural slate roofing.

How long is the warranty on synthetic slate roofing?

Most synthetic slate shingle manufacturers offer warranties of between 30 and 50 years for their products. Some shingles are guaranteed for life. As with other roofing products, the warranty’s length is a reliable indicator of the product’s quality.

Are synthetic slate shingles better than natural slate shingles?

Synthetic slate shingles are lighter and less expensive than natural slate shingles. While both are environmentally friendly roofing materials, synthetic slate shingles are easier to transport and install because of their weight and uniform size. They’re less fragile than natural slate, too.

Do synthetic slate shingles require less support than natural slate shingles?

Yes, synthetic slate shingles require far less bracing and additional preparation than natural slate shingles. The considerably lighter weight of synthetic shingles means they can be held in place on a standard roof using standard roofing nails. This makes roofing installation faster, easier, and less expensive.

    Extremely fast response and service. Highly recommend! The price was reasonable along with financing options. I bought a house this year without a roof inspection (Biggest L of the year), but this team was able to replace the entire flat roof in one day. So happy that I don't have to deal with any more leaks!

    By the time I connected with Certified, I had already gone through at least 3-4 window presentations. If your not familiar with the process, it's mostly full of high pressure sales tactics and overprices proposals. The folks at Certified did not take the approach. The owner of the company came out to do the survey. His approach was simple: we will provide you with quality windows at a fair price and customer service to ensure your satisfied.
    Certified delivered on all of these. Their pricing 20% to 50% less than anything we had received from the big name companies. The windows arrived earlier than expected, so the job was completed sooner than we were initially told. Quality of the windows is great and I trust that if we have any warranty issues that Certified will hold up their end of the deal. We had a few workmanship issues (mostly caulking) that we didn't catch right away, but when this was pointed out to their team, they quickly sent someone out to check it out, and a crew was out the following day to make the repairs.
    Overall a great experience. Big thanks to Tom, Diane, Koo, and The Crew.
