"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"

"I knew from the start I wanted a metal roof and that I wanted the Permalock product for its quality and durability, and that it looked like the shingle roof we had. The lifetime guarantee and product sold me. The roofers were great, and every night the place was cleaned up, very efficient company."

"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

Yes, shingles should overhang the drip edge, typically between 1/2-inch and 3/4-inch. An overhang shorter than 1/2-inch can allow wind-driven rain to get under the shingles and damage the roof deck or fascia. Conversely, an overhang longer than 3/4-inch increases the risk of shingles getting caught by strong winds, which can lead to roof uplift. Always check your local building code for exact overhang requirements in your area.

Mansard roofs are still popular in Paris, where they originated, and throughout France. In the United States, you can find mansard roofs on some older buildings in Manhattan. The architecture also appears on some Victorian and Colonial-style homes. There are pockets of homes with mansard roofs in New York City and Los Angeles, where they were once more popular than they are today.

Yes, chimney flashing is an important element in the complex system that is your roof. Chimneys (and anything else that goes through your roof) provide a great opportunity for water damage. Good flashing prevents a lot of potential damage. 

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.

Your chimney needs a structurally sound chimney cap, protective lining, damper, chimney flashing, and brick and mortar to prevent water from goind down your chimney. A pro can help you identify where the issue is so that you can stop water from coming down the smoke shaft, through your damper, and into your home.
