"We have a historic home and there was additional care required to replace siding beneath the roofing material at the eaves. The team at Jordan roof completed the entire job in only 4 days, they fixed up our dormer which had shingles that had deteriorated, and repainted some of the shingles. Our home looks better than ever! Great responsiveness, fair pricing, and high quality work."

"Highly recommended! Adam Tweedy and his team repaired our 'cool roof' and three patio decks in just two days. The crew was efficient, careful with our furniture, and the installation was impressive. The roof passed the water test, proving its quality. An added bonus: they didn’t need to remove our solar panels, saving us time and money. For a reliable, water-tight roof at a reasonable price, call Reign Roofing!"

"We are giving Hoyt Roofing a 5 Star rating, because of the excellent job they did on the installation of our new roof. The whole process only took four days and the workers went over and above to keep us informed of the progress and maintaining a clean work area. We were impressed from the initial meeting where we discussed and deciding on the terms and conditions to completion of the job. They were not pushy or try to upsell their products. We highly recommend this company to anyone who needs a new roof."

"Green Ladder Roofing recently completed a traditional tile roof on my home, and I am beyond impressed with their craftsmanship and attention to detail. From the start, their team provided a thorough consultation, explaining the process and materials involved in traditional tile roofing. The crew was punctual, courteous, and highly skilled. They worked diligently to ensure every tile was perfectly placed, resulting in a beautiful and durable roof that complements the style of my home. Their expertise in traditional tile roofing techniques is evident in the quality of their work. I highly recommend Green Ladder Roofing to anyone seeking a traditional tile roof. Their commitment to excellence and customer satisfaction is truly commendable. Thank you for restoring the beauty and integrity of my home!"

"I can’t thank Jonathan and the team at Roofing Angels enough for the amazing job they did on our full roof replacement. This was a huge investment for us, and we wanted to make sure we hired the right company. After getting multiple quotes, we went with Roofing Angels because of their professionalism, competitive pricing, and outstanding customer service—and we’re so glad we did! Jonathan was incredibly helpful and responsive throughout the entire project. He kept us informed on the progress, answered all our questions, and ensured everything stayed within budget. The crew worked diligently and completed the job in a timely manner. They were also polite, respectful, and left the site spotless when they were done. Our new roof looks fantastic, and we have peace of mind knowing it was installed with top-notch craftsmanship. If you need a new roof, don’t hesitate—Roofing Angels is the company to call."

Roofing questions, answered by experts

The most common defect in a flat roof is leaking. Flat roofs have minimal slope, so water pools more readily on a flat roof than on a sloped roof, and the risk of the waterproof membrane failing increases with exposure. Tears and punctures from foot traffic and blown debris are other common problems, especially with single-ply roofing membranes like TPO and EPDM roofs.

Roof vents are an essential part of a roof, as they promote energy efficiency by keeping warm, humid air at bay. The roofing material, especially asphalt shingles, will not last as long as it should (about half of its manufacture life) if the attic is not ventilated. Also, going without ventilation means having a warm attic that demands more from your air conditioning system (and your wallet, once the bills come). Ridge vents and roof vents also prevent a host of other icky moisture-related problems like rot, mold, and mildew.

Yes, many contractors offer warranties for their work. Confirm terms before hiring.

Roofing felt is the most common type of roof underlayment, likely because it has been around the longest. It’s called roofing felt because it is often made of felt soaked in asphalt. Depending on the type of roofing a home has, roofing felt comes in different thicknesses. 

If properly installed and maintained, roofing felt should last between 10 and 25 years. 

Roll roofs don’t last as long as traditional roofs, like those made of asphalt shingles. A roll roof typically lasts between five and 15 years, whereas a shingled roof will last between 20 and 50  years. Modified bitumen roofs are similar in look to rolled roofing but have a 12 to 15 year warranty.
