"They helped a lot with getting through insurance hassles and pushing to get the entire roof repair covered. Once everything got approved there were a couple scheduling conflicts on both sides. They did accommodate us on timing to not conflict with a toddlers nap schedule. There were a few small items left unfinished that took some time to get completed, but they did come out and address everything."

"We were extremely satisfied by all three phases completed by Kastle Construction. The roof was done first by Randy and his crew, they did a fantastic job. The windows and siding were installed by Brett and Allison and the finish project exceeded expectations. We commend all of them for being hard workers and paying close attention to detail and craftsmanship. We would highly recommend them."

"It was TERRIBLE.....From the moment I came home from work and saw the shoddy workmanship, I ctctd.a person by the name
of Matt.  They didn't look right at garage levvel...Matt gave me the runaround, which I am finding out is all that he does...That is
tell suckers like myself that they couldn;t do anything....Fast forward to last summer when I had my roof re-roofed and I
asked contractor what is sticking out from under shingles?  He said that was the old hangers for gutters He took about   10 
minutes to remove them......
         I have left calls with a Mike Lacina, who I believe is the son...He did return calls.Also, I did get them out here on  2 seperate
occassions, to bend back the "cover" on the highest part of roof,which is 2nd floor of house...
   Also google "scam informer" and u will see well written article from another displeased customer
     they only care about selling product and are very difficult to get warranty work...My last conversation was with Matt, who was
very stand-offish.....I asked him what was his capacity with Lacina...He said I don't have to tell you....He is the PRESIDENT"

FAQs for natural slate roofing installation and replacement projects in Medford, MN

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.
