"I will call this “The Good, The Bad and the Ugly review” as I am breaking this review into the 3 teams that we had – 2 very good and done quickly and 1 inferior with the most time spent at our house – thus the overall 3 star grade. The Good • Roofing Team – Grade: A. Efficient, good job, found virtually no nails or roofing materials on the ground • Gutters – Grade: A. One man crew but he knew what he was doing and provided good suggestions for modifying our water flow. The Bad • Siding & Window Team – Grade: C to D. Not sure how they were trained but they didn’t seem to understand some common construction basics. A few of the many examples – o They nailed the siding on wrong and had to start over. o They almost ripped the 120V electrical outlet off the house without turning off the breaker but it was the weekend and we happened to be in the garden and saw them. o Installed the dryer vent wrong twice – once painting it shut and the next time putting on a vent with a label on it saying “not for use with clothes dryers” due to the pre-installed screen. The Ugly • Siding & Window Team – Used caulk as touch up paint on LP Smartside (or just used the siding to clean off their dirty fingers?) – leaving random “chicken pox marks” all over new siding. Garage, driveway and all 4 sides of our house were filled with equipment and garbage for the length of the project. Not the crew to have if you have children or pets – they left old saw blades and other sharp objects around the garage entrance and the house. I didn’t expect a spotless home every night but I didn’t expect to be living with this much disarray with minimal clean up each night, even after asking the supervisor to improve pickup of at least garbage and sharp objects in the garage and the common walking paths. Nor did we expect to be spending our fall cleaning caulk off the “maintenance free” siding and re-painting it and installing our outside boxes correctly. I will give the owner credit for realizing that his siding and window crew did inferior work and giving us a discount on our bill. None-the-less, I am rating the services provided based on the quality of the work done."

"Hilda was easy to work with (she really knows everything about roofing). I appreciated that she was able to get me into her schedule before the winter season. Definitely would recommend J & B Roofing and would work with them again. A+"

"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."

"Great! MN Window and Siding has done several projects over the last 10 years for us in our mid 50’s Rambler. They replaced our Sliding patio doors in the Family Room, Picture Window in the Living Room, and 2 other windows-one in the kitchen and another they enlarged the opening and installed a crank out in a bathroom remodel we had done last year. The vinyl windows/patio doors they use are from Alside and are excellent quality. After the hail storm here in Bloomington in 2013 they replaced our roof. We had many color choices to choose from and the roof was completed timely and was great quality. Jim worked with my insurance company and the project went smoothly."

"Hoffman went above and beyond to replace my roof following hail damage. State Farm initially agreed to replace a small portion. Hoffman documented and chalk marked damage. State Farm replaced entire roof! Job was completed professionally and timely. Thanks"

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