"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."

"Manny and his crew were phenomenal! Diagnosed our issue, quoted us and completed in just 2 days. The siding matches completely and looks fantastic. We recommend them first for any and all work on the house. We will be using them again for another roof we own!!"

Roofing questions, answered by experts

An improperly installed skylight could potentially impact your roof's warranty. This happens because roofing penetration is necessary during skylight installation. Check your warranty information to verify. In most cases, having skylights professionally installed with proof that flashing is being done to specifications can be enough to preserve your roof's warranty.

You can install solar panels on a metal roof, but it will require some additional thought and care versus a traditional asphalt shingle roof. That’s because heat dissipates off a metal roof differently than asphalt or wood, so you may need to space the panels further from the roof. However, a pro can help you with the details and provide a safe and effective installation.

The proper specifications for furring strips can vary, so you should always consult the roofing manufacturer's guidelines or your roofer. However, general recommendations are as follows:

  • Thickness: Furring strips are typically 1 to 1-1/2 inches thick, meaning standard 1-by or 2-by lumber works well. In areas with extreme winds, a thinner strip may be preferred to limit how much air can get under the roof and cause uplift. A thicker strip can add slightly more insulation but will also increase installation costs.

  • Spacing: The recommended spacing for furring strips is between 12 and 24 inches apart on center. Proper spacing is crucial for ensuring good airflow, adequate drainage, noise reduction, and better energy efficiency. The ideal spacing can depend on the roof's pitch and the specific type of metal roofing being installed.

Unfortunately, there’s no definitive answer to this question, but the wind rating of your shingles will give you a good idea of what wind speeds can damage your roof. If you’re concerned about damage, inspect your roof following windy conditions to look for signs of wind damage to your shingles. When in doubt, consider hiring a professional who fixes roofs to carry out an expert inspection. Remember that hurricanes, tropical storms, and tornadoes are likely to cause the most damage, but even severe thunderstorms can bring winds that compromise your roofing system.

The level of underlayment’s water resistance will depend on the type of underlayment. The most popular underlayment, felt, is water-resistant, but it can’t withstand long direct exposure to rain or the elements. 

Synthetic underlayment is more waterproof, but asphalt is the only fully waterproof type of underlayment.
