"Excellent communication from the first meeting to look at the roof, through establishing the contract, scheduling, and completing the work. There was unexpected additional action required at the end of the project and, Rene, the Superintendent, followed up and had that completed ASAP. I also want to comment that the roof replacement was done on my parents' home in S.Calif. I live in the Seattle area. I had hoped to be there during the roof replacement but the timing was such that I could not be. Rene was accessible to me by phone or email if I had questions or was working through details on behalf of my parents. He always responded in a timely manner. Rene also went above and beyond by taking pictures of each stage of the project, emailing them to me with updates. My parents asked me to be on point so much of the communication came to me, yet Rene also kept my parents' updated. Jordan Roofing is professional, timely, and clean up was thorough. Excellent customer service and high quality work. Even the city roof inspector commented that Jordan Roofing Company does excellent work. I highly recommend Jordan Roofing Company."

"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."

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.

"I only hired his company to place a plastic tarp over my roof for temporary protection. Overpriced, but needed for emergency before the rain."

Roofing questions, answered by experts

You shouldn’t put a new roof underlayment over an old one for a few reasons. Old felt must be removed in order to assess the condition of your roof decking, such as rotting wood or other structural issues. Also, if your roofer doesn't install a fresh layer of felt as is required by shingle manufacturers, your warranty may be voided. Finally, old underlayment removal is often included in the cost of roof repair or replacement, so there's no real benefit to leaving it on before installing a new layer.

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

While you technically can add a roof over shakes or shingles, it’s not a good idea. Roofing over existing roofing creates a moisture barrier underneath the new roof and since the trapped material is wood, you can expect a moisture problem. While you could get away with installing a new roof over asphalt or steel, wooden roofs should be removed, new underlayment installed, and the new roof installed over that. Also, the extra weight would add strain to your roof structure.

Walking on any roofing material is dangerous, so you should avoid it if you can, but if the need arises, you should know that you can walk on a concrete tile roof without damaging it. Try to step on the bottom portions of the tile that are supported by the lower layer, and distribute your weight evenly across both feet and hands, if possible.

Most shed roofs can last between 15 and 30 years, although some roofing materials like slate and clay tile can last for 50 to 100 years.  Choosing durable, waterproof roofing materials that can stand up to weather and the elements will help your shed roof last for years to come. Besides the noticeable signs that your shed roof needs to be replaced, it might also be worth replacing if it’s near the end of its life span.
