"We live in a house that has a flat roof. It's also down a hill so you look down at my roof as you approachmy home. That's why the appearance is so important to us. I had several "flat roof experts" come look at the job and walk away. Bill (the son) didn't even blink. He immediately gave us the confidence needed to know these guys are the real deal. They took two layers of tar & gravel roof off my house and installed a high tech membrane and insulation. They had to drop the old roof down to the ground then hump it up the stairs into the dumpster. They came with 9 guys, Antonio was the crew chief. The nicest guys. And when they left, my property looked clean, without a single shrub or flower out of place. And the new roof is beautiful. Bill (the father) was here to supervise and really added to our confidence and satisfaction. I don't write a lot of reviews, but these guys deserve the shout out."

"This was the best experience I have ever had dealing with a contractor. Jacob and his team went above and beyond my expectations. Jacob was able to stay within our budget. Cost that was estimated is what was invoiced at the end of the job. We started off with just getting our roof replaced but then decided to put a new roof and siding on our garage. Everything was done within two days. Left the outside of our house spotless. I recommend JI Roofing to everyone that needs to get their roof and or siding done."

"This was a large job which required removal of the old roof - multiple layers of asphalt shingle and cedar shake down to rafters. The house is a large old Victorian with multiple angles and outcroppings, and very steep. There was also a one car garage. As promised, Royal arrived on day 1 - a Monday in 12 degree weather - with 3 dump trucks, several other trucks with men and equipment and over 30 workers. They swarmed over the house and by 10 AM the roof was stripped to the rafters and by the end of the day new plywood, underlayment and shingles had been installed on more than 3/4 of the roof. All work was completed in 4 days. Every night the property was thoroughly cleaned up. Progress was provided during the entire job by sending photos taken with a drone - terrific! Overall we were impressed and pleased with the work and the fact that it truly took 4 days. We had seen other jobs in the neighborhood take 3 weeks or more to complete. You pay for this kind of service - it is not cheap - but it is totally worth it. In addition, all of the workers and the project managers are very professional and attentive to your needs. I'll never have to use them again for this job, but I would recommend them in a heartbeat if you need a roof, gutters etc."

"I decided to have my roof inspected and replaced (if necessary). I had several companies come look at the roof and I decided on Brothers. After the inspection I was told it had to be replaced and I was given a presentation where I was told everything that would be done, I made a few decisions about materials and colors and gave him a deposit. It took 3 weeks because of other work they were doing and then the weather but they came and took down the roof the first day then came back and put on the new roof on Day 2. They worked nonstop both days and cleaned up the mess before they left. My new roof looks terrific and I am very happy with it. That was the good and now the bad. When I got my estimate ($9500) I was told the only other possible charge was if they had to replace any roof panels. I asked worse case scenario and he said all 65 panels would have to be replaced at $65 each (after 5 free) or $3900. I asked how likely that was and he said that he just completed 2 roofs and hadn't replaced a single panel. So of course 15 minutes after they start he tells me they have to replace all 65 panels. When he came by a few days later for the balance I meant to ask him about my discount but I forgot until after he left. I texted him but my text messages went unanswered until I sent an email to the company and I got a phone call within the hour. I explained that I paid $12,900 after a $500 discount but it should have been a $1,000 discount (website says $1k on projects over $10k). First they said that they gave a $9500 price so the $3900 additional cost doesn't count! Then he changed directions and said that he charged me $65 per panel instead of $75 per panel and when I told him he charged me what he quoted me, he said it could have been $75 per panel. It was obvious that he was going to say whatever he had to say to justify not giving me the discount I was entitled to. Bottom line: Make sure you get all charged and discounts in writing. I was disappointed in how they ignored me for days then gave a poor excuse. I said I would hire them again BUT if I did I would get everything in writing upfront!"

"Installation Date: Late August 2022 The roof installation and gutters were installed and look great. I DO NOT like what they did with the flashing on my chimney. It looked cheap, put together in haste, and with really bad and cheap materials. I had to call and argue with a representative to explain to him that the job they did on the chimney was horrible and that it had to be corrected. He tried to convince me it was the way it's done. I then showed him my neighbors house who had their roof done by another company. Power Home charges a premium and it didn't seem like they were very invested in the job they were doing. Additionally, the trash bin that was delivered was way to small and all the trash didn't fit. As a consequence, they left trash in front on my house and on my property for weeks after. I had to call a second time and resort to begging to get them to come by to pick up the trash. Overall, I feel like they didn't respect the job they were doing, the final touches were horrible, and they didn't treat my home with love or respect (as if it were their own home). Also, there is now a huge gap between the siding and the new roofing material. I fee they should have found and budgeted for a solution for that issue in the form of a bit of siding or flashing to minimize that gap. Now water and critters will get in through that gap. Overall, if I could do it again, I would defiantly NOT chose Power Home Remodeling. I DO NOT recommend them."

"Jake and his crew did a great job, I was adding solar panels to my roof and wanted new shingles and plywood to support the installation. I called several companies and found JAGG to offer the best price. I was very happy with the work, one day, full crew everything done. very impressed with the cleanup, not a nail to be found. LI Solar even asked for there information!! If you need Roofing , siding or Windows give JAGG a call. Excellent, 5 star work!!"

"I highly recommend Good to Go!! We did a major home renovation this summer. We completely remodeled our kitchen, put in hardwood floors throughout the first floor, re-faced a fireplace, and painted every room. We knew Good to Go was the right company for us as soon as we met Paul. Paul called the day after I requested a quote and he was punctual every time he met with us. He was very easy to work with, very knowledgeable, and gave us great suggestions and ideas. The price he was quoted was in the middle of other quotes we had received, but we had no doubt he was the person we wanted to work with. Good to Go is a family business and we loved everyone involved with the company. They are all great people who we felt very comfortable having in our home. They did incredible work and we couldn't be happier. They cleaned up everyday when the day was over and they let you know what their plan for the week was. Our water heated started leaking and needed to be replaced while the project was going on and they had a plumber at the house right away for us. We even worked with Paul's son Clark, who is a carpenter, on a custom TV stand. Clark is truly an artist! Paul made sure that everything done in the house was exactly what we wanted and goes the extra mile to make sure everything is done right. Josh was also great to work with and really did an outstanding job in making sure that we were totally satisfied. Doing a home renovation can be stressful and overwhelming, but Good to Go really made it a very pleasant experience. We were happy when the job was completed, but we miss seeing the guys everyday. I cannot say enough good things about Good to Go and they will be the only one we call for future projects!"

"We have a two story home in Patchogue that had a leak that resulted in water in the walls of our attached garage. We could not locate the cause of the leak. We contacted Exterior Team Home Services who quickly located the source of the leak which required us to replace the front roofing of our house. It was done very quickly at a fair price. We were also impressed on how they made sure the old roofing material did not get into our front lawn or plants. They were meticulous in the way they treated our property. A job well done."

FAQs for natural slate roofing installation and replacement projects in Smithtown, NY

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.
