"Home Genius were punctual, professional, and concise! Jose, the project manager, took care of and answered all my questions or concerns I had about the roof replacement. Jose called the day before with all the details of the job and made sure that I was comfortable with everything that was discussed in the contract. After the job was done, Jose was very quick and communicative with closing out the job and showing me, in detail, how the roof looked and what they installed! I did not feel stressed mainly because Jose was on top of everything that was going on and I really appreciate that. And the clean up job from the crew?? Fantastic job! So great!!"

"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."

"Using Angie's List to identify contractors, we solicited four local roofing companies. Chuck Scandroli, the owner, came to my home as scheduled and soon after presented us with a detailed plan and cost proposal. His plan, and personal attention and demeanor, led me to want to use Scandroli Roofing for this work. The entire roof was replaced, along with all gutters and downspouts, and an older skylight was replaced as well. All of the work was professionally done. The employees were courteous and helpful. The entire job took about 3 work days, and when done there was no mess or trash left behind, and virtually no nails found lying in the grass or driveway! Scandroli brought in an outside contractor to do the interior finishing for the skylight, and Johnson Drywall did an excellent job. We were extremely happy with the quality and professionalism of Chuck and his company and highly recommend them to anyone needing roof or gutter work."

"In 2017, when I was looking to purchase a house in the Rockford area that was needing a full siding install I contacted GF Company in Belvidere. IL, who I found on Angie’s list and at that time GF Co had great reviews. Strangely enough these great reviews are no longer to be found on Angie’s List. It should also be noted there is a GF Siding in Cherry Valley. IL, this is Not the company that I did business with. Ariel Zmijewski (the owner) got me a quote quickly and I decided to purchase the house. A few months later in July 2017, I contacted Ariel again to discuss the finer points of the quote, the price was revised slightly and the Ariel mentioned that once a deposit was paid work could start 6-8 weeks later, but said the install would be finished before the cold weather arrived. I started creating a color layout and Ariel provided some feedback on what would work and not work. To this point I was very happy with progress. In September 2017 I paid a deposit of over $8k (about 44% of final price) and awaited updates for a start date. Nothing happened. In early March 2018 I contacted GF Co by phone stating that I had been very patient and they had had $8k as a deposit for the last 6 months and I had nothing to show for it. After a couple more calls and emails Ariel showed up with his foreman Mark and they said that work would start in the middle of the following week. Much to my surprise the work started on time. Over the course of the next 4 weeks Mark and his crew worked hard, only missing a few days due to bad weather, I even agreed to having some extra work done by the team, some wooden entrance steps that needed replacing for an additional $2.5k. By early May 2018 the job was finished the house looked great and I was very happy with the work and appearance and was getting compliments from neighbors too. The balance of owed of over $10k was paid with 48 hours of the work being finished. Again I was happy with work done, until… A few months after the install a TV cable box started having troubles. Cut a long story short the wall socket died because cable was suddenly defective, also the crew had moved the exterior cable input box and this didn’t help the issue. Comcast fixed it, but I now have an exterior cable showing and they had to drill through the siding. Then around Halloween 2018, less than six months after having the install completed, I noticed that a piece of siding (6ft approx.) had become detached underneath a window, trying to pop it back into place did not resolve the issue. After checking all the other exterior windows I noticed 1 other window was about to do the same thing. I called the GF Company main number and left a message with the receptionist for Ariel to contact me. No response. I called again a couple of times and left more messages still no response. In March 2019 siding problem under windows still Not fixed, I called GF Company again, no answer, and no voice mail. I called a couple more times on different days still no answer or voice mail. I then sent an email to the company and to my surprise I received a response from Ariel stating this was the first that he had heard of it. About a week later (3/26/19) he showed up at my house to view the problem. Ariel stated that he would get someone over to fix the problem, but would not give me a date or time. On 4/2/19 I emailed Ariel again asking for confirmation of a repair date ? Nothing but crickets… On 4/30/19, I sent another email to Ariel requesting that the repairs be completed before the end of May 2019, again no response. Quote / contract says: Customers will receive a Lifetime Warranty on Material and Workmanship Reported GF Company to Illinois BBB on 6/5/19."

"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.
