"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"

"They did a great job repairing my mom's roof from a tree falling on it. They also resealed her cracked asphalt driveway the same day and they did a great job on that too! Their prices were reasonable. I would recommend them to a friend."

"Excellent team and communication for our roof project. We needed someone to repair our roof that has shingles thats been needing repair and they were able to deliver and spring into action within a day ! It was perfect as the rains were coming and the damage to our roof would have gotten worse. From the time I first communicated they were able to arrive and give us an estimate and work with our insurance company (which was not easy) in the same day. Highly recommend this company ! Thank you"

"I'm a return customer. They did our replacement windows a few years ago, and they just replaced our asphalt roofing shingles. They did a wonderful job. I was amazed and impressed with how quickly, and how well, they completed the job. I love my new roof."

Roofing questions, answered by experts

A square of shingles covers 100 square feet and usually ranges from 150 to 240 pounds. It all depends on the material and type of shingle.

Roofers most often use nails to fasten roofing shingles and other roofing materials. Nails have more holding power than staples and offer better weather resistance and longevity. However, it is possible to use staples instead of nails when installing a roof. Staples are less expensive, but not as high-quality.

There are several pros and cons of flat roofs. One disadvantage of flat roofs is that you lose potential attic space because it's flat. Flat roofs tend to pool water and because they lack an angle, any leak in the roof—usually due to a bad seal—has the potential to let in a lot of water. They don’t work well in climates with snow. Flat roofs are also structurally weaker than sloped roofs.

The easiest type of roof to build is a shed-style or lean-to roof, which features a single sloping plane from one side of the building to the other. Unlike a gable roof with two sides meeting in the middle, a shed roof's single slope makes the construction process more straightforward. The rafters are typically single pieces of wood that span the distance, often without the need for additional supports.

Technically speaking, yes, verbal agreements and “handshake deals” can be legally binding contracts that will hold up in court, but the suing party will need to be able to prove that the parties entered into the contract. Even though verbal and handshake deals can be binding, it’s risky to rely on these types of agreements for anything, including roofing projects. Always aim to get your contract in writing, and make sure it includes all terms and that you don’t agree to additional terms that don’t appear in the contract.
