"We used NextWave Construction for our new front door and storm door. From start to finish, the process could not have been better. Dave arrived at our house and went over options, walking us through the entire process. After selecting what we wanted, Dave handled HOA approval, and maintained contact with us while waiting for the door. Install was perfect. The crew was extremely professional and did a fantastic job. Dave followed up again to ensure we were happy with the outcome. I highly recommend NextWave Construction. Outstanding customer service, high quality products, and perfect installation. Not much more you could ask for in a company."

"A fantastic experience. I have a complicated roof with several valleys and angles. Chuck S. was a total professional, and I have total confidence as he guided me thru the options and choices. The precision and care of the installation was impressive, down to the small details. The installation crew was as hard working of a crew as I have ever seen. The tone was set by the owner being up on the roof with one arm in a cast pounding nails as fast as anyone else. Every night there was a 100% clean up. The level of care shown by the crew is summed up in one incident. My wife was in the yard and picked up a small piece of paper. One of the guys pounding nails stopped working to yell at her to stop doing that. Picking up was his job. This is the 3rd roofer I have used, and I will never call anyone else."

"I would totally recommend this company! Ariel went above and beyond for me when replacing my roof and gutters! Ariel would call me and let me know he was on the way or if he was running even 5 minutes behind. My house looks great and I will be using them again come spring to start replacing some of my windows. Thank you Ariel! Your crew was great, too."

"All Star Installations Inc was professional in every way. We had our roof replaced and our chimney cap repaired. They did both jobs with skill and precision. They were thorough, hardworking, and an immense pleasure to work with. They did a tremendous job from start to finish and the clean up was impeccable. We couldn’t have asked for a better experience. The new roof and chimney cap on our home looks amazing! I highly recommend All Star Installations Inc. Ryan and Chris are top notch!!"

FAQs for natural slate roofing installation and replacement projects in Cortland, IL

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.
