"We contracted Home Genius to complete our windows, Hardie siding, and gutters, and the entire experience was excellent from start to finish. Install Manager Dylen, Project Manager Dakota, Sales Representative Zach, and Crew Chief Dennis all played a key role in making this a smooth and successful project. The team was punctual, professional, and highly organized throughout the process. The crew worked efficiently while still paying close attention to detail, and it was clear they had a lot of experience working together. They took the time to answer our questions, kept us informed along the way, and made sure everything met our expectations. The quality of the workmanship really shows, especially with the siding and window installation, and the cleanup afterward was just as impressive—our property was left in great condition. Overall, we are extremely satisfied with the results and would absolutely recommend Home Genius to anyone looking for reliable, high-quality exterior work."

"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."

"They came and looked at our roof but unfortunately they do not understand what an estimate means. The customer is expecting to pay a certain price for certain repairs. Nothing more, nothing less. This company likes to include open ended clauses in the contract which would allow them to charge more as they see fit when they get the job and the competition with other providers is over. This is just unacceptable. Nobody hires a company without a clear budget unless they want trouble."

"It was time to replace my roof and I requested several estimates from roofing companies. I selected Marshall Roofing Siding and Windows. It was not the cheapest estimate but the estimate assessment by Mr. Chris Butler, of Marshall Roofing, was the most thorough. Mr. Butler inspected the roof, went into the attic (and found a bathroom vent venting into the attic instead of outside), went into my screened in porch to determine what kind of nails to use so that they would not come through the tongue and groove ceiling and he noticed some old satellite dishes that could be removed. Marshall roofing updated the proposal several times with all of my concerns and additions. This is great customer service! When it came to choosing a shingle color, we struggled to find the right color. Mr. Butler kindly offered to bring out additional shingle samples to us on a Friday afternoon. Again, above and beyond customer service. Mr. Butler also worked with us to find and install an attic fan specifically designed to be quiet when running. The job started promptly on time and was finished in two days. Mr. Butler came out as the job was wrapping up and when the crew finished packing up, on his own, he did a second magnetic sweep around my house to find any nails that may have been missed during the magnetic sweep performed by the crew. Again, great customer service! We are very happy with the workmanship and customer service that we received from Marshall Roofing and would highly recommend their services!!"

FAQs for natural slate roofing installation and replacement projects in Manassas, VA

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.
