"I just had my roof replaced by Home Genius Exteriors, and I couldn’t be happier. The initial presentation and inspection were phenomenal — super detailed, honest, and easy to understand. They kept that same level of professionalism all the way through the project. Great experience overall. The installation crew arrived right on time, worked tirelessly, and completed my entire roof replacement in just one day. After finishing, they thoroughly inspected and cleaned the area—front, back, and even my neighbor’s property. The workmanship was outstanding, and their customer service was honest and straightforward. Pricing was fair, and the overall experience exceeded my expectations. If you need roof repairs or a full replacement, Home Genius Exteriors is the company to call. I highly recommend them."

"I am a senior with a background in construction.  After reviewing many contractors and speaking with some of them, I immediately knew I hit the jackpot when I spoke to Danny.
 
1.  He knew exactly what I needed and wanted done when I first spoke to him.  This entailed the replacement, repair, and installation of the items listed above with attention to quality in materials, prevention of future problems, a fair price, and a commitment to starting and showing up once the job was initiated.  Danny exceeded every expectation in these regards!
2.  I silently knew in advance manufacturers, quality and cost of exterior doors (including the french door), storm doors, door locks and deadbolts, leak-proof door sills for 6 inch exterior walls and a leak-proof barrier on the bottom of the door frames.  Without knowing of my preferences, Danny suggested the identical manufacturers and materials I had in mind.  At this juncture, we met and I hired Danny to perform the work.
3.  I am beyond pleased with the outcome of Danny's effort on this project.  As an example of his integrity, he asked me to trust him in the design and installation of an exterior octagonal window in a bathroom.  My wife and I were literally blown away with a handcrafted symmetrical waterproof tunnel and inside wall frame he created - more akin to an artistic piece than a window.
4. Inside work was always minimally invasive using tarps and soft shoes rather than work boots.  Outside and inside cleanup at the end of each work day was respectfully performed leaving no mess.
I would recommend Danny to anyone requiring any kind of interior or exterior installation, modification, or repair as I have seen firsthand examples of his experience, skills, and personal and business ethics.  In fact, Danny is presently working on costs to replace our roof."

"Excellent work, service, price!! All Exteriors was 1 of 5 companies I contacted for a quote. Bill came and walked roof, explained material options, addressed all my concerns with various leakpoints I’d discovered upon moving into my home. He communicated promptly regarding scheduling, his crew was great, they worked efficiently to complete my roof same day. They cleaned up all the materials upon completion and showed me at different points how they addressed the pre-existing damage/leaks. I will definitely use All Exteriors again. In fact, planning to hire for exterior wall of home that also has extensive water damage (from roof problem). Unfortunate to have this going on with newly purchased home but having a reliable, competent contractor makes a huge difference."

"The installer very sensibly installed the replacement gutters to match the previous installation. This placed the downspout  about 2 feet from the end of the gutter. As I realized this would lead to pooling in the space between the end of the gutter and the downspout and be a breeding ground for mosquitoes I voiced my concern to the installer who had just finished doing a very fine job.
    After consulting head-quarters he agreed to reinstall just to make me happy. I asked if he thought a simple patch over the existing downspout hole as well as installing a whole new gutter (which he was preparing to do at no extra cost). He looked relieved and said it could be guaranteed to work well. The downspout is now attached to the end of the gutter and I am very satisfied.
    I will definitely be using this company again and will highly recommend them to anyone who asks.

"Very happy with the results and the process was easy and smooth. George Jr showed up to do the consult, he was very friendly and knowledgeable. They were not the lowest quote we received but they were the best at communication and wanting to earn our business. As sales people, my wife and I appreciate professionals that still go out of their way to earn business. They were even able to get in and do the job before the Thanksgiving holiday which was only a few weeks from the consult and was very important to my wife, as we had 14 people coming to Thanksgiving dinner. She is also pregnant and they offered us products that would not be harmful to her or the baby, but she ended up being out of town the days they were here so we stuck to the normal paint, but really appreciated the effort to accommodate us.
   The workers showed up exactly when they said they would. They worked hard and were very fast. I was amazed they finished everything in 2 days considering the size of the area they were painting and the number of cabinets and trim we had. The workers were respectful when moving and covering our belongings before and after painting. They were always laughing and smiling during the job, which is good to see, it hopefully mean they enjoy what they're doing and the quality shows. George and his son would pop in from time to time to check in and make sure everything was going well and that we were happy with the progress.
   All in all, very happy! Would recommend to anyone! If fact, we need new granite.....you know how it goes, first new appliances, which means new paint, which means new counter tops and so forth, but George Jr mentioned they can help us with that and we will probably be giving them our business for that job as well. Thanks for the great job guys.

"Very satisfactory. He came on time to see what needed to be done. He and my son looked it all over and decided how to repair the roof. Mr. Stehm (I believe that is his name, pls forgive my mistake if I'm wrong) gave the most reasonable price. I got another estimate from another outfit for $1,000.00. Mr. Stehm came on the appointed day and fixed the roof w/in a reasonable (4) hours. Also, he cleaned up after himself.

FAQs for natural slate roofing installation and replacement projects in Royal Oak, 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.
