"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."

"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

No, you can’t use your home’s square footage. You have to calculate your roof’s square footage, and then you may have to convert your square footage measurement to correspond with how the roofing material is measured. For instance, some roofing is sold in “squares,” which equals the total square footage of the roof divided by 100. Shingles are sold in bundles that may not correspond to the number of squares you need. Metal roofing is sold as sheets, so determine the amount of square feet each panel will cover and then divide the total square footage by the coverage area.

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.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

Installing solar panels involves drilling small holes in your roof to secure the solar panel mounting brackets. These brackets hold the solar panels in place and must withstand strong weather conditions so they’re secured into your roof. However, holes and screws are sealed to prevent leaking and further damage.

Depending on the condition of your roof, you may be able to add flashing to it. If you’re looking for a way to maintain its integrity while saving some money, you should ask a roofing pro if this is an option. Keep in mind that if your roof is in poor shape, a full replacement may be necessary before flashing is installed.
