"This company is very shady and unethical. We selected them because of the price. It was substantially lower than other quotes received. The reason it was lower was because it wasn't accurate. With the dumpster in our yard, and the roofing materials delivered only then did they "discover" we also needed all new planking. We were prepared and budgeted for a $21,300 project. Suddenly we needed to come up with an additional $8,500 for the plywood. This was part of all the other roofer's quotes. When I voiced that I wanted to use another company they told me I signed a contract and they planned to enforce it. If I broke the contract I would have to give them 1/3. I had no choice but to cave. When I pressed on why this wasn't discovered until they started- they had no response. I was stuck and was forced to proceed (or walk away from $7,100). BEWARE!!! 6/25/2025"

"I hired this company from a list provided by Angi. I was looking for someone to repair my concrete, painted driveway. They first wanted to replace the driveway, but their price for that was $49,000. The only alternative they offered was to patch over the cracks and spalling on the existing concrete, and then repaint. That price was $8900, so I went with that option, with the understanding that they couldn't guarantee how well the patching would hold through the winter. I hired them based on their 5-star rating on the Angi list. They did an OK job with the patching, but there are two big problems with their paint job: 1) they didn't wait long enough to allow the patching to dry, so after two weeks the paint buckled over the patching, and 2) they didn't use a separate primer, so the paint didn't adhere well and peeled up in several places. I've called them several times. They keep promising to come back and fix these areas as a "courtesy", but they never show up."

"I hired Liberty Windows & Siding for a large exterior renovation project that included siding, windows, doors, gutters, and a portico. I selected Liberty largely based on representations that the work would be performed by in-house crews rather than subcontractors, and that quality workmanship was a priority. Unfortunately, the project did not meet those expectations. The initial installation resulted in widespread workmanship deficiencies, including improper siding installation, flashing issues, trim defects, and other items later documented by both an independent inspector and a manufacturer representative. As a result, Liberty had to remove and reinstall significant portions of the work. While Liberty ultimately undertook remediation, the process was prolonged, difficult to manage, and required extensive homeowner oversight. Remediation details were not consistently documented in writing, work was at times scheduled or attempted without prior coordination, and key quality-control"

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