"Clearly the best of the bunch. Very honest in accessing the roof and estimating the associated costs. While we are not going forward with reroofing at this point in time, we will be contacting Nick at Bormann Brothers when we do!"

"We spent all summer talking with siding contractors. All of them disappointed us for various reasons (costs, games, delays). We finally contacted Lakewoods Remodeling, and we are very glad we did. Their pricing was very reasonable, and they did not play games. They started when they said they would start. They finished when they said they would finish. They used high quality materials. They did high quality work. They showed concern for making everything look good (and it does). To summarize, the value they provided was excellent. We would definitely use them again, and we highly recommend them."

"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!"

"The initial work of replacing fascia, soffits and gutters was done professionally and quickly. For that they rate four stars. However, there was a repair that needed to be fixed. Repeated requests, over the past several months by email, text, and phone, have received little to no response. The repair is still not completed."

"Kerry and Adam, were great to work with. They always called back with any questions we had and were very pleasant. We had hail twice in one year August and October. Our insurance was really difficult to work with, They didn’t want to pay. They worked really hard with our insurance company sending pictures and answering any questions they had. We got a new roof and siding with their help, which looks great. They also helped my parents get a new roof which the insurance didn’t wanna pay for. They also helped a friend of mine get a new roof also siding, her insurance told her she didn’t need a new roof, but the funny thing was everyone around her needed a new roof, she was so thankful for the guys helping her out. The crews that work for them, that did our siding and roof and windows were all very pleasant and they also did a great job cleaning up."

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