"It went incredibly well. I woke up one morning to a leak in my roof. I knew the roof was going to need to be replaced at some point, but I was hoping I'd get another year out of it. The roof was in bad shape when I bought the house. I immediately started calling all of the roofing companies I could find on Google. It was early so I was leaving voicemails. Kasey from James and Whitney was the first and only one to get back to me in a timely manner. He was incredibly helpful on the phone, walking me through how to put a tarp over the impacted area. He even swung by later THAT DAY to check and make sure it was installed properly and to assess the roof. I knew it needed to be replaced so we went right into talking about estimates. The estimate was within my budget but the new roof came with a FIFTY-YEAR WARRANTY for parts and labor. You just can't beat that kind of warranty on an asphalt roof. We were scheduled within a week and I had a brand new, perfectly installed roof within a month. Kasey and his team were super respectful during the installation. When the installation had finished, Kasey inspected every inch of my property to pick up any tiny bits of trash and leave our lawn spotless. The whole process was so easy and stress-free. 10/10 would recommend!"

"Bryan did a fabulous job replacing my roof. His team did the whole job in one day. They stripped the roof in 2 hours, replaced with certain-teed shingles, and cleaned up all the old roofing. Bryan cost was the least of all 5 roof estimates. I highly recommend Bryan and his crew."

Roofing FAQs, answered by experts

You should hire a roofing professional to install a metal roof, as it’s an essential part of your home and a difficult installation. Your roof provides the most protection for your home among all of the building materials, and any mistakes made during the installation process can quickly lead to roof leaks, water damage, and significant repair costs. A roofing professional will ensure your new roof is installed properly and according to building code to minimize that risk, and they will usually back the installation and materials with a roof warranty for added peace of mind.

You can technically install a metal roof over asphalt shingles, but it isn’t a good idea. This is because you’re essentially creating a moisture barrier under the metal, which can easily—and often does—lead to significant mold damage. Removing an asphalt roof isn’t terribly expensive, and some roofing companies might cut you a serious labor and disposal discount if you add it to a new install.

Proposals, invoices, and estimates are most often used as marketing documents and are not legally binding. Contracts are legally binding documents that detail the service offering, project considerations, and signatures from all parties. If you signed a proposal for discussion purposes while requesting a quote and you decide to hire your roofer, make sure the contracting party follows through with a legally binding contract to protect both parties.

More and more insurance companies are writing torch down applications out of their liability insurance for contractors. If torch down is covered, they generally require a worker to stay on site for two hours after the last flame is extinguished.

For this reason, cold application modified bitumen—also known as “peel and stick”—is becoming more popular, and torch down is decreasing in popularity. Modified bitumen is taking its place, as it uses both hot and cold applications.

The most common slope, or roof pitch, for a shed is 4:12 or four inches of height for every horizontal foot. For areas that experience heavy snow loads, a steeper roof of 6:12 or 9:12 is best.
