"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."

Roofing FAQs, answered by experts

Stripping existing shingles and installing a new shingle roof takes a professional one to two days, and sometimes up to three days for larger roofs. Additional safety measures necessary for steep roofs can extend the timeframe even further, as do added measures, like replacing roof decking or reinforcing your roof structure to support heavier materials like slate or clay.

It’s possible to walk on a clay tile roof, but you run the risk of breaking or cracking the tiles if you’re not careful, so it’s best not to walk on it if you can avoid it. If you or a contractor needs roof access, be sure to distribute your weight evenly and step on the portions of tile that are also supported underneath, which depends on your tile design. Walking on any roofing material is inherently dangerous, so wear rubber-soled shoes and use safety equipment if you need to access your roof.

Some people prefer to use connectors consisting of galvanized metal to replace the birdsmouth cuts on the rafter board. Common names for these metal pieces include hurricane ties and variable-pitch connectors. Making birdsmouth cuts is more cost-effective than purchasing these connectors for each rafter. However, because making large birdsmouth cuts to accommodate extra-wide exterior walls can weaken the rafter, a connector may be the better option in some cases.

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.

Metal roofs last for between 50 and 70 years, and asphalt roofs last for between 20 and 25 years, with some lasting as long as 30 years. In most cases, you’ll get double the life or more out of a metal roof than you would from a shingle roof, which helps make the higher cost of a metal roof more manageable.
