"Their bid came in much under the others we received. They installed a GAF lifetime warranty shingle. We were flexible as to when it could happen. They scheduled the work, then called a week ahead of that to come and get it done. They arrived an hour after the appointment, but were watching the radar to make sure there would be no rain. A crew of 12 showed up and were completely finished in 6 hours."
Bormann Brothers only uses one experienced crew. If you read our reviews they are all positive. If you hire us, you’re getting the same crew that did the work from the review.  You get the A-Team every time. You don’t have to worry about getting a C team like other bigger companies.
Nick and Steve Bormann started the company in 1997. They’re still at the job site every morning!

"I received excellent service from Keyprime Roofing and Remodeling. ! I received a step by step explanation of the roof replacement, by the owner of the company and in terms I could understand. The quote was provided promptly as well. The pricing was fair and I shopped around before signing on with Keyprime so I know this with certainty. The roof is just beautiful and it was installed in 1 day. All of the workers, were professional. This is a company that was a pleasure doing business with! Susan"

Customers say: Quick response

"Could not be happier. Greg and Eddie were knowledgeable and professional and courteous. Eddie handled all the liaison with my recalcitrant insurer. The workers were courteous, prompt, reliable and professional. All in all, a stress free project as soon as Chismar came on board. Looking forward to working with them on any future projects!"

"It couldn’t have gone better! The crew came tore off the old roof. After they got the old roof off a storm front came through. These guys were up on the roof with a giant tarp strapping it down makin it water tight and I never had a single leak. It’s a pity that it’s a flat roof because it’s truly a work of art and no one else can see it. I’m exceptionally pleased that they have offered to come back in the spring to make sure that everything is still OK. I only have one roof , but if I had another I wouldn’t think twice about hiring them again. They were easy to work with and really know their business."

"Forever Fortified really came through! Before the project started they visited and went through all the details thoroughly and gave us a few options to choose from and was no pressure, they also gave some recommendations for other areas of the house. The actual work itself was on time and perfectly executed, any change of plans was communicated and there were no surprises in the end. Overall highly recommend them and will use them in the future!"

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