"Met with 5 different roofers for an estimate, but these guys were the most thorough, very cool technology for us to see video of our roof, inside the attack view, so we could see what was needed. Kyle, our rep, was very knowledgeable and didn't try to sell us on things we didn't need, worked to make it affordable for our options. Then Justin and the crew came and did an awesome job replacing the roof in one day. Highly recommend!"

"Long Roofing went above and beyond when installing our roof and gutter. The job turned out more difficult than we thought it would be but Long Roofing made me feel comfortable and reassured that they would fix everything. Everyone involved from the salesperson to customer service listened to our needs and treated me with respect. The roof looks amazing. I don't want to get into price, but even though you may get someone less expensive, using Log Roofing was well worth a little extra cost"

"Tar Star Roofing (Anthony) responded in one day, inspected my roof and provided a quote the next day. The crew started work a couple days later, very professional, experienced and courteous. They completed the job on time and to my complete satisfaction. Communications from Anthony were constant, including recommendations on additional repairs as damage was found, photo documentation and expert advice. I highly recommend Tar Star Roofing for any roofing needs."

"The crew at James & Whitney co were extremely friendly, courteous and went out of their way to make sure that we were happy with our new roof. The job was done fast and is of wonderful quality. Beyond that, this is a company that truly stands behind their work, as they have reached out to me several times in the past few months to ask how the roof is holding up. I truly couldn’t recommend James & Whitney highly enough to anyone who needs work done on their roof."

"Excellent! Derek and his crew were very professional and courteous. They arrived on schedule and took great care to ensure our bushes, deck and stairs were protected from any falling materials from the roof during the job. In the middle of the job, we received some rain that day and the crew made sure to cover any exposed area on the roof at the time. We would definitely recommend them to others."

Roofing questions, answered by experts

Gaps between tiles are necessary to help with weatherproofing, allow for thermal expansion, and increase wind resistance. In general, a small gap no larger than 3 millimeters wide will encourage proper drainage and limit cracking. Beyond that, tiles should overlap a minimum of 3 inches, except at the eaves where they should extend to the center of the gutter.

There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.

Many roofers remove satellite dishes as part of their services, especially during roof repairs or replacements. However, they typically won’t reconnect or reinstall the dish. If you no longer need the dish, roofers can dispose of it, but for reuse, you may need a satellite technician to handle reinstallation.

Gable roof construction can last for 100 years or more without needing structural repairs, although the lifespan depends on your climate. Since gable roofs are great at shedding rain and snow, the actual roofing material on top will last for between 20 and 100 years or more, depending on the material you choose. If you’re unsure that your gable roof is up to par, have a roof inspector take a look.

It’s always a good idea to have a lawyer review any legally binding contract before signing, including roofing contracts. Most contracts have straightforward language that’s easy to understand, but getting advice from an attorney before signing could save you from being locked into a contract you don’t want to move forward with. Having a lawyer review your contract can also help protect you if your roofing professional defaults on their side of the agreement.
