"Two years ago, our HOA experienced a hailstorm that destroyed most of the roofs in our corner of our HOA. It was a time when our part of Colorado was experiencing a lot of severe weather. Getting in touch with an insurance adjuster not to mention a roofer was near impossible. So we resorted to our circle of family and friends, and they recommended NIWOT ROOFING. One call later we had their roofer getting past our insurance company's backlog and they scheduled an inspection of our roof, with both our roofer and our insurance adjuster on our roof together. Both were in agreement that our roof needed to be replaced. After that the Niwot Roofer agent took care of all the paperwork and in no time, we had a contract and a scheduled date to replace our roof. They even managed to do it when my wife and I were on vacation in Hawaii. They did the job in ONE day and even kept us informed by sending us drone pictures of every step of the replacement, so we knew what was going on in real time. W"

"Chris at Five Sons Roofing was fantastic! Straightforward and had our best interests in mind. We were originally looking to fix a leak in our flat roof over our back patio, but after inspecting the roof, Chris recommended a full roof replacement. After approval, Chris took us through the project with great communication and efficient work. He and his crew were done in one day, and the new roof looks fantastic. I will recommend Five Sons to anyone who needs roofing done!"

"I was the victim of a local criminal contractor, who installed a roof on my house that was garbage, that failed county inspection, that needed to be replaced. This criminal (ira Siegel @ Colorado Storm Solutions) refused to make it right. My only recourse was to take to social media to warn others about this lowlife. Brian Barnes of Colorado Native came across one of my postings and reached out to assist. Within days, Brian came to the house to inspect the roof. Brian then reached out to roofing shingle manufacturers to seek donated materials to lower the costs, as well as donating crew time to make this possible. I have never experienced such a reaction from a business previously, a local contractor with a true sense of community to right a wrong. I could not recommend any business, or service, more than I could recommend Colorado Native. And the previous contractor, well, he lost his licensing privileges in the Larimer County as a result. If you have an interior or exterior project and are seeking a contractor you can trust, Colorado Native is the contractor- quality work, integrity, and a sense of community."

"A metal roof was installed as part of the construction of a new residence. The metal roof included incorrect materials that were installed improperly. Ready Roofer was able to replace the roof with their superior Euroshield hail-proof product in a timely way. I appreciated the level of supervision and quality that went into the replacement roof. I would strongly recommend Ready Roofer for projects in Northern Colorado."

"After purchasing our new home and enduring an especially cold and snowy winter, we noticed that water was collecting in our gutters and seeping into the drywall. This turned out to be the result of an improperly installed roof edge that would not allow snow and water to be pushed away from the house. We contacted Virtuous Roofing and asked if they could send someone over to review. They responded almost immediately and had a crew inspecting our roof the next day. The boss, Edgar, personally reached out to confirm the arrival of his crew. He even delivered the materials to fix the roof himself! Edgar took the time to show how his crew had replaced the roof under the guidance of the previous owner. The next day, the crew was back and quickly installed the new roof edge. They were very easy to communicate with, and under Edgar's guidance, I feel like we are in good hands should anything else come up with our roof and gutters!"

"Went great! Greg got his crew there fast and got the tear off and new roof on quick. His crew cleaned up all roof stuff from around the house. He worked well with inspectors. No issues, he even came back to touch up paint on a roof vent."

FAQs for natural slate roofing installation and replacement projects in Milliken, CO

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.
