I have had them replace my entire roof and down spouts on my home and the work was done fast and economical with excellent results.

Very reasonable price for a storm door install (I received some outrageous quotes from other companies). Everyone was super responsive and the job was done quickly. Easy to work with and will keep this company in mind next time we have exterior projects.

First rate service all around. Had to rearrange our office meetings so the work could be done. Weather then caused a 1 day delay. Very good communication and coordination. Highly recommend

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.

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.
