We had Thornberg Construction repair the damage to our home after the Nov 2024 bomb cyclone. They were absolutely marvelous, very professional and so easy to deal with. Mitch and the crew showed up each day on time and worked hard through the day to get it done! They worked with the insurance and were very quick to answer any questions we had—would not use any other contractor on future projects.
Thornberg has reroofed my garage after their inspection found severe water damage in the attic. Mitchell’s professionalism put my mind at ease as he walked through all the areas of repair and helped identify the cause, which resulted in a successful insurance claim. Kevin was great during the bidding process explaining all options and providing all required information for the insurance claim. The replacement was as painless as a roof replacement could be, they were expedient and efficient. They cleaned each night and had a thorough post inspection process. They are a family owned business would highly recommend and use them again for any home remodeling or repairs, great experience!
Quality, communication, professionalism, collaboration, cost, and schedule - Thornberg delivered on it all for us during our remodel (upper story addition, new kitchen, bathroom, flooring, entryway) - going with them was perhaps the best decision we made throughout the project; absolutely zero regrets and a ton of relief.

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.
