Customers say: Quick response

"MJ Roofing performed flawlessly. At the time of quotation, Jose accurately told me when construction could begin, and how long the construction would take. Jose was on the jobsite every day to oversee the work. The crew showed up on time every day. The roof was installed perfectly down to evenly spacing the screws. MJ roofing even had a maid come to my house at the end of the job to clean up the dust. I wish every contractor in Key West was as dedicated to their work as MJ roofing. I am proud of my new roof and highly recommend MJ roofing."

"My mother hired Comfort Cover Systems to replace the roof on her home in Sarasota after Hurricane Milton. While the roof replacement itself was completed, their workers caused significant damage to the lanai carport roof by walking on it, which resulted in buckling and structural issues. Instead of taking responsibility for their actions, the company has repeatedly tried to downplay the damage and shift the cost of repairs onto my mother, a senior citizen. Despite multiple follow-ups and visits from their representatives, their proposed "solution" is completely inadequate. They cut off protruding screws and offered to paint over the damage, but this does nothing to fix the underlying structural issues or the buckling they caused. To make matters worse, their response tried to blame the lanai’s condition on pre-existing wear and tear from the hurricane, even though the damage was clearly caused by their workers during installation. This attempt to avoid accountability is both insulting and unprofessional. When we informed them that we would withhold the final $12,000 payment until the damage was resolved, they responded with vague promises but no real action plan to repair the roof. They also made communication unnecessarily difficult by asking who the "decision-maker" was, despite being told multiple times that all correspondence would go through me and my mother. A reputable company would stand behind their work and resolve such issues promptly, but that has not been the case here. I strongly urge anyone considering Comfort Cover Systems Inc. to look elsewhere. If they damage your property, you can expect excuses, deflection, and an unwillingness to take responsibility. My family is now left with no choice but to escalate this matter to the Florida Department of Business and Professional Regulation and the Florida Roofing and Sheet Metal Contractors Association. Save yourself the frustration and find a company that values its customers and takes pride in doing the right thing."

"The company had repaired leaks in my 1996 barrel tile roof after the 2005 hurricane season. Other leaks occurred with the recent hurricane, so I decided to go with a metal roof. I knew that barrel tile roofs do not prevent rain infiltration onto the underlayment, allowing water flows into valleys to erode the underlayment, causing the leaks and rot. The code underlayment quoted (2 separate layers) is more robust now, but I ordered at extra cost an even more robust underlayment. The company contact was more than helpful in arranging for "custom" installation. The installation team was meticulous in doing the custom work, very professional, the company contact checked in every day, my property was cleaner when they left, the office answered all my inquiries within 24 hours, a real homeowner-friendly contractor. If I lived further inland, I have no doubt I would have been equally happy with the standard installation."

FAQs for natural slate roofing installation and replacement projects in Key West, FL

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.
