"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."

"I had new windows installed today and I couldn’t be happier with the entire experience. The crew arrived early in the morning right on time and immediately got to work. They were incredibly fast and efficient, but never rushed through the job — everything was done with care and attention to detail. What really stood out to me was their professionalism and work ethic. They worked steadily throughout the day without unnecessary breaks and made sure everything was installed properly before wrapping up. The team was respectful of my home, kept the work areas clean, and made sure to answer any questions I had along the way. The finished product looks amazing and I can already tell a difference. I’m extremely pleased with the quality of the installation and the overall service. I would absolutely recommend this company to anyone looking to replace their windows."

Together the John Krause team creates a superlative custom home building and home improvement experience tailored to the needs, wants and dreams of each client. We are passionate about our client relationships and this is reflected in all that we do. From the in-house design process, interior and exterior customization and artisanal craftsmanship to the professional management and accurate fixed pricing, our aim is your total satisfaction with your new home, architectural restoration or home remodeling project. 

"I am writing to formally express my deep dissatisfaction with the recent retaining wall replacement project completed by John Krause Construction (JKC) at my property. After reading positive reviews and receiving an estimate that, although over my budget, seemed reasonable for the work involved, I made the decision to hire JKC. Unfortunately, this has proven to be a significant mistake, and I am left extremely disappointed with both the quality of work and the overall experience. Here are the main issues I encountered: 1. Unprofessional Behavior: The crew exhibited unacceptable behavior while working on my property. Not only did I witness them disposing of bodily fluids on-site, but they were also disrespectful and dismissive. when I raised concerns no response was received. I now smell urine when entering and exiting my garage. 2. Unresponsive Ownership: I have attempted to reach out to the owner multiple times to address these concerns and resolve the issues, but my messages have been met with silence. This lack of communication is incredibly frustrating and has only added to my disappointment. The owner refused to speak on the phone since the owner was made aware of the call being recorded. 3. Property Damage: During the construction process, my property was left damaged in multiple areas. This included e.g., landscaping destruction, equipment damage. Personal crew members vehicles being driven through my yard leaving deep tire marks damage. 4. Subpar Quality of Work: Despite the high cost of the project, the final result does not meet the standards outlined in the estimate or contract. No proper grading was completed. Every time it rains pools of water sits in front and behind the wall. The response received was. “we have passed all inspections.  There will be some water pooling while it is settling still. Plus the fact of the hard rain today, it will happen.” The wall has been completed for 2 months. Given the extensive problems, stress and anxiety I have faced. I do not recommend John Krause Construction."

Our experienced team, based out of Sterling, Va, has built a reputation for providing high-quality residential and commercial roofing services at affordable prices. Give us a call for a quick consultation. We'd be happy to schedule a free estimate and provide you with all of the material and warranty information you need to help you make your decision.

"Overall, the workmanship was excellent, the price reasonable, and most importantly, Augustine continued to build a huge amount of trust with the customer through an honest and transparent process from beginning to end. Scheduling the initial estimate was easy and timely, good communication continued through the contract process, but we had to wait two months for word on work scheduling. Dakota Biller was a Godsend. He expertly talked through the full scope of options, pros, and cons. He listened to our unique needs, provided helpful guidance, and did not attempt to upsell. Installation was professional and cleanup was thorough. The final product looks magnificent! Price was the most reasonable of all highly ranked companies primarily due to Augustine’s willingness to only replace rotted fascia with new wood. Their 10-year warranty provided peace of mind. This was a RARE hassle-free project, and I cannot recommend Augustine Roofing enough."

"Spent ~$50,000 on a new roof with them. Thought everything went well. Years later discovered that they had not sealed the cricket on the chimney well enough. Discovered water coming in and eventually rotting the wallboard, studs, etc. Had to replace entire wall. Called them about the issue, they sent a rep. He said it was the chimney's fault, it was leaking. Not so, opened the wall and ceiling and had another roofer come spray water on the chimney, nothing, no leak. Then sprayed water on the cricket, water came in. Exterior Medics would not admit any fault. Had it repaired, no leak, no problem since then. Had recommended to a friend, never gain, he also had a bad experience. DO NOT USE IF YOU WANT QUALITY WORK AND A COMPANY HAT STANDS BEHIND THEIR WORK."

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