"I want to have my roof inspected for a potential repair or replacement. Robert responded fast and provided honest review by telling me that my roof is coming to the end of the expected life but didn't push me to replace or repair right away. Additionaly he found cracks on my chimney that I was not expecting initially. I am happy to hire him to get the chimney fixed and potentially saved a lot of money for a fix down the road. I will highly like to hire Robert again for roof replacement."

"American Home replaced my roof and siding, porch windows and some add-on exterior lighting. One of the reasons I chose AHR was not just due to the best price, they came in line with other estimates I received, but because they included things with their final price that similar companies had as add-ons at an extra cost such as the dumpster and gutter system. I did not know what to expect as this was the first time I've had these things replaced. My rep John was awesome, he was professional, friendly and accommodating, and was able to work with me on the spot vs. "I have to check back to the owners" which I got from other companies. John was readily available by phone, text, and in person. He walked me through all the steps, timelines, and the whole process. After the crew finished, he took my list of 'nit-pick' things and made sure they were addressed. Overall I am satisfied with the job, In fact, we recommended them to our neighbors who hired them to do their siding this Spring."

"Signed a contract to replace half the roof for $5000 after assurance of no hidden cost and nominal cost for replacing some plywood. Due to rough weather the job was performed 3 weeks after signing. The roofer did not cover the roof with tarp and also spoke to Allstate who denied all my claims for damages. I was billed $1600 in addition to $5000. I have paid the $5000 but I deem the extra billing excessive. I was not informed of the cost for approval. I am willing to come to terms with the contractor and would like Angie’s list to review and work out a compromise. It also points to the level of service offered by the two contractors referred by your company. One bid for $2500 and precision roofing came in at $5000. I signed with Precision because of their assurances as an established company with a fixed cost. It has turned out not to be the case."

FAQs for natural slate roofing installation and replacement projects in Mahwah, NJ

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.
