"I am a senior with a background in construction.  After reviewing many contractors and speaking with some of them, I immediately knew I hit the jackpot when I spoke to Danny.
 
1.  He knew exactly what I needed and wanted done when I first spoke to him.  This entailed the replacement, repair, and installation of the items listed above with attention to quality in materials, prevention of future problems, a fair price, and a commitment to starting and showing up once the job was initiated.  Danny exceeded every expectation in these regards!
2.  I silently knew in advance manufacturers, quality and cost of exterior doors (including the french door), storm doors, door locks and deadbolts, leak-proof door sills for 6 inch exterior walls and a leak-proof barrier on the bottom of the door frames.  Without knowing of my preferences, Danny suggested the identical manufacturers and materials I had in mind.  At this juncture, we met and I hired Danny to perform the work.
3.  I am beyond pleased with the outcome of Danny's effort on this project.  As an example of his integrity, he asked me to trust him in the design and installation of an exterior octagonal window in a bathroom.  My wife and I were literally blown away with a handcrafted symmetrical waterproof tunnel and inside wall frame he created - more akin to an artistic piece than a window.
4. Inside work was always minimally invasive using tarps and soft shoes rather than work boots.  Outside and inside cleanup at the end of each work day was respectfully performed leaving no mess.
I would recommend Danny to anyone requiring any kind of interior or exterior installation, modification, or repair as I have seen firsthand examples of his experience, skills, and personal and business ethics.  In fact, Danny is presently working on costs to replace our roof."

FAQs for natural slate roofing installation and replacement projects in Woodside, DE

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.
