The entire process was extremely easy and straight forward. There was no mess to clean up. The process took less than a business day from start to finish. I would highly recommend this company.

Kelvin and his entire crew were so respectful, efficient and professional! They went above and beyond by helping us clear out the attic and get rid of stuff! They also made sure that any nail pops were fixed and the new attic space looks so clean. Even today I think the house is warmer and the furnace isn’t working as hard as before. Their cost was very reasonable too.

Kelvin and the team were super responsive and great to work with. They removed all the old sheathing and insulation from under our finished deck, sprayed, and resealed everything in just a day.

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.

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.
