"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"

Roofing questions, answered by experts

Properly installed chimney flashing can last anywhere from 15 to 50 years. However, flashing generally only needs to be replaced when it is damaged, corroded, or no longer creates a watertight seal. Several factors influence its longevity, including the material type, quality of installation, and local climate. For example, copper flashing tends to last longer than galvanized steel. Large storms and extreme weather can also damage flashing, potentially requiring earlier replacement. To ensure its longevity, it is recommended to have your chimney and roof inspected annually. A professional can assess the flashing's condition and recommend any necessary repairs.

DIY is possible for minor repairs. Professional services ensure proper sealing and alignment for larger issues.

While the terms are often used interchangeably, wood shakes and wood shingles have notable differences, primarily in their manufacturing and appearance. Wood shingles are machine-cut on both sides, resulting in a smooth, thin, and uniform product. In contrast, wood shakes are typically hand-split or sawed on only one side, giving them a more textured, natural, and rustic appearance. Due to these manufacturing differences, shakes are generally thicker, heavier, and less uniform than shingles. They are also more expensive. Homeowners seeking a more rustic aesthetic often choose shakes, while those preferring a more uniform look may opt for shingles. Both are installed in an overlapping pattern to create a durable, weather-resistant roof.

The best material to sheath a roof will depend on your budget and if you require the strength of more robust materials. For most homes, the added strength is unnecessary, and oriented strand board, or OSB, makes sense. It’s inexpensive and robust enough for most roof types. Another popular but slightly more expensive option is plywood.

The length of time you can leave a leaking roof before it causes damage will vary greatly depending on a variety of factors. The best approach when it comes to roof leaks is to play it safe and fix it as soon as possible, whether you take the DIY route or hire a roofing professional to inspect, diagnose, and repair the problem.
