TL;DR Avoid this company.
I had my roof replaced two years ago by SmartRoof.
A couple of days ago, I asked another roof company to check my roof due to the damage caused by the bomb cyclone. All the plywoods under my 2-years old roof are growing molds!! I have to replace all the plywoods, thus the 2-years old roof, again because of that.
I deeply regret using the Smart Roofing two years ago.

We had a tree crash through the roof, they came through when I needed someone on short notice. These guys were excellent, prompt and very easy to work with! Highly recommend them

We had our original 25 year old roof and gutters replaced by SMART Roofing. The crew worked their tails off and finished the roof install in just two days. They cleaned up all of the material each day and kept their work area very tidy. Everyone I interacted with was polite and professional and Thiago kept us informed throughout the entire process. The price was very competitive and I feel that we got every penny's worth.

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.
