"Chad and his crew were absolutely amazing. From the first sales call, until the last nail of completion, I knew we could count on him. He had been referred, and we immediately felt comfortable with Chad, as he patiently explained the value in a significant undertaking - this roof will be there another 200 years, the quality is just that good! The work was on-time, professional, and the crew did a great job of cleaning up when they are done. We plan to use Metal Roofs Direct for other roofs when the time comes!"

"I saw their notice regarding free estimate for attic insulation at the  Home/Garden show.  I left my information and they contacted me about a week or two later.  We scheduled an appointment.   Jason came out and inspected everything, we discussed options and he gave me estimates for both.  I was going to be out of town for a while and he said he would extend the home show discount until after i got back.  I scheduled the installation with Tina - she checked back with me (both email and phone).   John and Nick showed up a little late on the install day, as their previous job ran longer than expected.  Both Nick and John were very professional and personable.  They explained what they were going to do and let me view the work in progress, as i was curious.  They answered all my questions and did a great job in cleanup - even vacuuming the grass :).   I am pleased with the work and am looking forward to the savings the added insulation will provide."

"Came out and repaired the roof where the shingles had been blown upwards. Included pictures of the roof and actually found another spot potentially bad and patched that also. Was fixed in a matter of hours from when I first called."

FAQs for natural slate roofing installation and replacement projects in Jefferson, WI

A slate roof features thin tiles of natural stone installed over a solid deck and underlayment. Formed under intense heat and pressure, slate is exceptionally durable and delivers a distinctive, high-end look. Because the material weighs far more than asphalt, most homes need added structural support before installation. 

While upfront costs are higher and routine inspections are a must, many homeowners choose slate for its unmatched longevity and curb appeal.

Slate stands out for its 50- to 200-year life span, low maintenance, and classic aesthetic. It’s fire-resistant, energy-efficient, and often boosts resale value. 

On the flip side, slate runs far more per square foot than asphalt, weighs up to four times as much, and demands a contractor who specializes in the material. Tiles can crack on impact, and repairs cost more because the work is slow and precise. If your budget and structure can handle it, slate delivers top-tier performance for generations.

Natural and synthetic slate aim for a premium, stone-like appearance, whereas asphalt focuses on affordability. Real slate runs $10 to $30 per square foot installed and lasts up to 200 years; synthetic slate costs $10 to $15 and tops out at 50 to 100 years. 

Standard asphalt averages $3 to $8 per square foot and needs replacement every 20 to 30 years. If you want the slate look without the full price tag—or extra roof weight—synthetic is a solid middle ground.

With routine inspections and prompt repairs, a natural slate roof can last well beyond 100 years; some hard-slate installations reach the 200-year mark. Soft slate falls in the 50- to 125-year range, and synthetic products last 50 to 100 years. 

Remember, flashing, fasteners, and the underlying structure may need attention sooner than the stone itself. Severe hail or fallen limbs can also shorten life span, so schedule periodic checkups with a slate-qualified roofer.

If you plan to stay in your home long term—or want a standout selling point—slate delivers strong value. Although installation costs are high, owners often recoup 60% to 70% at resale and enjoy lower replacement cycles than asphalt. The stone’s durability, energy efficiency, and timeless curb appeal also appeal to eco-conscious buyers because fewer roofs end up in landfills. Just be sure your framing can handle the weight and that you budget for occasional specialty repairs.

Skip the DIY climb if you have a slate roof. Slate may be tough against the weather, but a single misplaced step can crack a tile and create a leak path. The surface also turns slick when wet, upping the risk of injury. Professional crews use staging and hook ladders that spread weight across multiple slates, protecting both the roof and the worker. To inspect or repair slate, call a roofer who specializes in the material.
