"I was really impressed with the experience working with Spicer Brothers for a new roof on a home built in 1994 that has hardly seen any improvements. Every step from the estimator through the installation went smoothly. When I met Dwayne on the job he was friendly, informative and helpful. His crew worked steadily and were finished well ahead of the estimated completion time. The new roof looks great and knowing the materials and workmanship that went into the installation I know I can rest easy for years to come."

"Thank you James Im, Antonio and crew for an amazing experience and a job well done! It is rare these days to find a home improvement company that you can trust from beginning to end. AHC staff and representatives ensured that every detail from estimates, to coordinating delivery of materials and quality control of installation was performed to the highest standards and exactly on time. James and Antonio/crew were attentive to our every question and concern, and in the end made the experience with AHC a memorable one worthy of the highest level recommendation. Bottom line: If you choose any other roof replacement contractor - you will be making a mistake!"

"Dannie came to our home in August and gave us a verbal estimate on the job; he never gave us a written estimate which I believe could have prevented the misunderstanding about what the price included. He was not able to start the job in a timely fashion because he was involved in another job and the homeowner kept adding projects which kept pushing our job back. When Dannie started the job, he re-laminated our kitchen countertop and he did an EXCELLENT job! He also installed a new stainless steel kitchen sink which turned out to be the wrong one which had been shipped by the supplier (not his fault). This complicated the whole project and ended up increasing the price...again not his fault. Dannie was pleasant and stood behind his work but I felt that he needed to be more detail oriented. I had to call his attention to several things for him to resolve them.

"THEY WERE GREAT! I HAD CALLED ANOTHER COMPANY WHO DECIDED TO DO THE HIGH PRESSURE STUFF AND REFUSED TO GIVE ME AN ESTIMATE UNLESS I BOUGHT TODAY.
DAN FROM GUTTER PROS CAME OUT MEASURED IT UP AND LET ME KNOW I COULD TAKE AS LONG AS I NEEDED TO MAKE A DECISION. THEIR PRODUCT WAS GREAT TOO. I EXPLAINED I WANTED TO CHECK THEM OUT AND READ REVIEWS ON THEM AND THE PRODUCT. SO I TOOK A FEW DAYS AND GOT BACK TO THEM. 
LOVED THE INSTALLER, WILL, ALSO.
I HIGHLY RECOMMEND TO ANYONE LOOKING FOR A GREAT PRODUCT AT A GREAT PRICE.
WE HAVE HAD PINE NEEDLES CLOGGING THE GUTTERS FOR YEARS, I WAS JUST FED UP.
SO, I AM EXCITED TO HAVE THIS DONE.
THE OTHER COMPANY THAT WAS OUT WAS LEAF FILTER OR GUTTER HELMET, I DONT REMEMBER. THE GUY WAS NICE ENOUGH BUT WAS GETTING MAD WHEN I TOLD HIM THAT I NEEDED TO DO RESEARCH.
SAVE YOURSELF SOME TIME AND CALL THESE GUYS.

I contacted George's Painting because of all the great reviews on Angie's List and am very happy that I did. I at first contacted them via email and received a prompt reply saying George would be out at 10:00 am on a Monday. I emailed back that that would be a good time for me. At 10:30 no one had come so I found a cell phone number for George who answered immediately and apologized and offered to come right away, which he did. He had not gotten the message about the 10:00 am appointment, which can happen when others are involved. George arrived and quickly understood what we needed done: we have 5 dormer windows that all had rotted wood around the glass as well as the sidesf. George suggested replacing it with PVC which will last many times longer than wood, and I was thrilled with that idea. He also suggested PVC for the outside frame of our little garage door, which had rotted away. He discussed using the highest quality Sherwin Williams paint, as well as washing the siding which had never been washed before. I was concerned that a power wash would take the paint off of our 30 year old siding but he said it wouldn't and he was right. I had had another company on Angie's list (the same company who had painted our house about 6 years ago) give me an estimate a week before and they never offered to wash the siding, only the mildewed part that they would paint. The other company said I could wash the siding myself and never offered to replace the rotted wood with PVC. They wanted to do what they had done the last time they were out which was to fill it with bondo or wood putty.  George repeated many times that they would make the house beautiful and do whatever it took to make it that way. He explained that first a crew would come out to wash the house, then another crew of carpenters to find and replace all the rotted wood, then another crew to scrape and paint. I did mention that I would like the window sills and any other surface sanded, not just scraped, but unfortunately this did not happen. I think they would have if I had asked them to but I assumed they would since I had mentioned it to George. However, the final painting job looks very good, although the little garage door really should have been sanded. However, this was the only minor thing that happened that I feel could have been done better.

The guys that washed the house were extremely careful and used a low pressure wash to methodically squirt every piece of siding from top to bottom. They did not miss one spot and I cannot believe how beautiful and clean the house came out. I even joked that now it did not need painting since it truly looked clean and fresh just from the chlorox wash. They were able to get all of the green off and every speck of black mildew, even under the eaves. These guys spent half a day just doing this.

The next work day, the carpenter Joel came and tested every piece of wood for rot. Wherever there was rot, he removed it all and cut a precise piece of PVC from the large sheets and long framing lengths he brought with him. He had all of the right equipment and was very good at measuring and cutting. He honestly worked for 5 full days and replaced twice as much as I thought there was to be replaced. I even called George and said I didn't know there was so much rot and I expected to pay more than the estimate because Joel was truly finding more - including window sills and the undersides of our mansard roof. George said he would charge just for the extra material they had to buy, which is what he did.

The next week, a large crew came and George showed me the Emerald Brand of Sherwin Williams paint and the two kinds of caulking they would be using on the house. He also pointed out that he first put primer on, then the paint, and didn't just use paint with primer in it. I had been worried about the caulking because I know that that is as important as paint for protecting against moisture, and the guys came through. Every gap was found and caulked with new white caulking appropriate for the material (siding, brick, or wood) that needed to be caulked. They must have had 6 tubes of caulking for our house. The guys worked from 7:00 am until 4:00 pm and finished in one day. George even surprised me by showing me a gallon of paint he had had especially mixed to paint our brown shutters and front door! I had not even asked for this, thinking we would just paint the white trim, and at first I was reluctant because I didn't think painting plastic shutters was a good idea, but George tested a small sample and I was sold. When the painting was all finished, the shutters and front door turned out to be the Piece de resistance! It made our house look 20 years younger and as fresh as a model home.

We couldn't be happier with the painting job.

"Great quality of work and customer service. After over a year of deliberation and several meetings with Paul Rosner and his designer (for which they were very patient), I finally decided on a plan for a new bathroom and wet bar. Everyone I have worked with has been great-- Ed (project manager), Marty (foreman), and the contractors. They were respectful of our house and our space. The quality of the work is excellent, and any questions or concerns were brought to my attention right away so I could make a decision on how I would like to proceed. I could have gotten the work done cheaper, but I would have paid the price in the long run with inferior quality and customer service. I am a very satisfied customer."

FAQs for natural slate roofing installation and replacement projects in Unionville, MD

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.
