- They are communicative professionals who do excellent work.
- Russ was super responsive getting estimates and during the bidding process.
- The crew was also great. They did excellent work and took good care of our landscaping around the house.
- Their communication is top notch, their work was excellent, and the price was very fair.
- I was impressed with their responsiveness and quality.
- My only disappointment was the size of the truck they used for haul away - it was small and they had to take it frequently.

My partner and I have made NSC our go-to any time we need work done on our house. They are communicative professionals who do excellent work. We always solicit bids and they are always competitive. So far, we've done three projects with them and will definitely be calling again next time we need something! Big thanks to Russ, Tony, and the rest of the team!

Russ was super responsive getting estimates and during the bidding process. Competitively priced (wasn't my first priority though), masterful weather forecasting in navigating the crummy weather this spring and his team did fantastic work.
I had three layers of composite shingles stacked on one another. Apparently 3-4 tons of material EACH. To get it all done and the roof sealed in the one dry day we had in a week, they hit it with an army of people but by doing so, were able to finish the job at a time when others would not have been working. Working from home that day may not have been the best idea (I have new respect for people living through a shelling now...) but they got the job done, well, and you'd almost not known they were there after they left.

I contracted North Star Construction to replace an eight foot front window, and five smaller basement windows. From start to finish I was impressed with their responsiveness and quality.
In particular, I'd like to call out their reaction to a complication that arose in the installation of the basement windows. The original windows were single paned and were embedded into the concrete. That is, the concrete was poured onto the window frames. This meant that removal could compromise the structure of the house. Where a lesser company would have shrugged and continued installation regardless of the consequences, North Star stopped work and notified me of the issue. As a result, we were able to call in a structural engineer and work out a solution that didn't compromise the structure of the house and didn't significantly raise costs.
I have a fence that needs replacing soon, and North Star will be the first company I go to for that project.

The average roof replacement cost for a residential home typically ranges from $7,000 to $15,000, depending on factors such as roof size, chosen materials, roof pitch, and labor rates in your area. Premium materials or complex designs may increase the price.
The cost to replace the roof of a commercial building typically ranges from $5 to $12 per square foot, depending on several factors such as roof size, material, labor rates, building type, and local code requirements.
Several factors influence roof repair cost, including the extent of the damage, roof accessibility, material type, labor costs, and whether it’s a general repair or an emergency fix. Minor repairs can start around $150–$400, while major repairs may exceed $1,500.
Roof leak repair cost generally ranges from $300 to $800, depending on the size and location of the leak, the materials required, and labor intensity. Complex leaks involving structural repairs or interior damage will cost more.
Flat roof repair cost for commercial properties usually ranges from $500 to $3,000, depending on the roofing material (TPO, EPDM, PVC), the extent of the damage, and roof accessibility.
Mobile home roof replacement cost typically ranges from $3,000 to $8,000, making it generally more affordable than traditional home roof replacements, due to smaller size and simpler structure.
It's not necessary to stay home during roof replacement. Roofing work is noisy and can cause vibrations inside the house, which might be uncomfortable. Most homeowners choose to leave during major parts of the project, but our team ensures safety and keeps you updated, whether you're home or not.
The timeline for a roof replacement typically ranges from one to three days, depending on the size and complexity of the roof, weather conditions, and material type. Larger or more intricate roofs may take a bit longer, but we always aim for efficient, timely completion.
To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.
Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.
When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.
Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
