"I received 8 competitive bids for a full roof replacement on our 1901 Victorian B&B. We chose Exterior Solutions LLC, whose bid was 28% below the average. The 4,000 sq ft project included removing 35-year-old asphalt shingles, installing all new plywood sheathing, and updating roof venting. The roof has over 45 facets with a predominant pitch of 10/12, making it a challenging job. John A. and his team did an outstanding job installing CertainTeed Landmark Pro shingles. John scheduled the work while our B&B was closed and ensured the roof was sealed before any rain. He worked closely with our neighbors to minimize disruptions. Cleanup was exceptional—nothing left behind. We’re extremely pleased with the quality, professionalism, and communication throughout. Highly recommend Exterior Solutions LLC for any roofing project."

"E.R. Roofing installed hardiboard siding on my house and new windows throughout the house. They were careful and professional in every way. The quality of the work is second to none. The pricing was very fair. And the after-the-job customer service has been nothing but over-the-top. Elliott is responsive and cares about his customers, which is why he will be the one to install the next roof on my house when it is time to do so. I can't say enough good things about E.R. Roofing."

"5-star ratings do not come easy. Eric responded to my request to replace the roof on my shed. Not a big job but it needed to be done. He came out, never tried to upsell me on anything, gave me an outstanding price, performed the work, did a super job, they check off all the boxes in my book. Would use them again in a heartbeat. I did get other estimates which it would have been cheaper for me to just replace the shed. Thanks Eric greatly appreciated. Eric took care of his crew on a hot day, another box checked off on my list."

"Power Home Remodeling has been fantastic. We had them come out to replace our gutters and were very impressed with the quality of their work. The crew that did the job kept everything clean and organized; you wouldn’t have known they had been there, which is uncommon for many companies. We were so impressed that we are now moving forward with replacing our siding. Everyone at Power Home Remodeling has been incredibly helpful throughout this process, and we couldn’t be happier. We will work with them on future home projects."

"Very disappointing. The firm was very late in its installation work - months after it promised. Its anaylsis of our gutters was unreliable. and its responsiveness in correcting its work was slow and required multiple calls and emails."

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