Posted on Susan PhillipsTrustindex verifies that the original source of the review is Google. J.J. Landerman Roofing recently replaced a small portion of our roof which was low pitch and had rolled roofing. I cannot say enough about how happy I am with this company. Jenn gave us a fair estimate, was very responsive, provided pictures of the job as it was being done and cleaned up well. We highly recommend this company for all your roofing needs!Posted on Howard GoldickTrustindex verifies that the original source of the review is Google. The J.J.Landerman Company installed a new rubber roof on my house 13 years ago. This was necessary because I had had the roof repaired twice in the previos 5 years. The Landerman rubber roof gave me no trouble for the last 13 years. Unfortunately a leak developed last week. I called Landerman and two men came to my house. They inspected the roof, found two small holes, and repaired them, all in less than 1 hour. I recommend the Landerman company to anyone needing replacement or repair of a roof.Posted on Marco VernaTrustindex verifies that the original source of the review is Google. We have worked with J.J.

Jenn & Team did awesome work and left the work site cleaner than they found it.Posted on Charlie DanceTrustindex verifies that the original source of the review is Google. Working with JJ Landerman has been an absolute pleasure. Jenn from the company had been my contact through the whole project of getting my roof replaced. She was on it every step of the way, from getting the installers out the day after I called to get an estimate, to sending the roof to an outside source to ensure the installation would be done correctly. The scheduling was tough due to the unforeseen weather problems, with the non stop rain, extremely cold weather but Jenn was on top of it throughout it all. Now that the job is completed, I could not be happier. On top of having a new roof, they had the clean up done before I even noticed, dumpster removed and all. I really appreciate such a easy process from JJ Landerman and Jenn. Thank you!!!Posted on Meghan KoenigTrustindex verifies that the original source of the review is Google. JJ Landerman - Jen and her roofers were skilled, timely and considerate. From the quote to the finished product, we could not have asked for a better experience. Jen gave us a quick and competitive quote. The roofers were on time, did a great job, and took their time to clean up after they finished. We highly recommend JJ Landerman Roofing to anyone who needs roofing services.Posted on Alicia RoncariTrustindex verifies that the original source of the review is Google. I had an excellent experience with this roofing company from start to finish. Jenn was great to work with; she was knowledgeable, responsive and kept me informed. The team was professional, punctual and incredibly thorough in their assessment of my roofs condition. I would highly recommend J.J. Landerman to anyone in need of roofing services!Posted on Brad WaitsmanTrustindex verifies that the original source of the review is Google. I had a great experience with J.J. Landerman roofing. I had a leak on my roof which is not new and called a few places to take a look and get quotes. J.J. Landerman roofing was very honest and said I only needed a repair and not a replacement. Other companies said they wouldn’t try to fix it since they were concerned the shingles would break. I mentioned to these other companies that I had a company (J.J. Landerman roofing) that was very comfortable with just fixing it and they still wouldn’t entertain it. When I mentioned this to J.J. Landerman roofing they could have easily said they agreed with the assessment however they stuck to their own opinion and made me feel very comfortable with just the fix. This saved me a lot of money and their price to repair my roof was very reasonable. Jennifer at J.J. Landerman roofing was very easy to work with and kept me in the loop throughout the process. I highly recommend J.J. Landerman roofing!Posted on Jeanette GoyzuetaTrustindex verifies that the original source of the review is Google. Had a great experience with Jenn! She was always responsive and friendly. The work started and ended within the specified timeframe and looks great. The only downside was that some of my plants were crushed but I was given a credit to cover it. Overall, I would definitely recommend using them for your roof.Posted on mike SmithTrustindex verifies that the original source of the review is Google. My experience has been wonderful. From estimate to work execution, everything was completed on committed time. The work was done exceptionally well at a competative price. They even ran a magnet over my driveway and lawn to be sure all stray nails were picked up. They left my driveway and yard cleaner than they found it. At the final settlement, the invoice was exactly as we agreed. No surprises. Would i recommend? Yes, and i already have.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

Slope & Profile:
Materials & Membranes:
Installation & Equipment:
Design Considerations:
Building Types & Uses: Commercial like Offices, retail, schools—roofs carry moderate loads (HVAC, foot traffic) and emphasize energy efficiency and aesthetics. Industrial like Warehouses, factories, plants—roofs must withstand heavy machinery loads, chemical exposure, extreme temperatures, and large expanses.
Materials & Durability: Commercial can include shingles, metal panels, and single‑ply membranes. Industrial typically relies on extra‑durable single‑ply (TPO, PVC, EPDM) or heavy‑duty asphalt systems (BUR, modified bitumen) with thicker reinforcements.
Scale & Complexity: Industrial roofs cover far larger areas (often 20,000 + ft²), requiring more extensive planning, longer installation times, and higher maintenance costs.
Most roofing systems fall into one of three broad shape categories:
Gable Roof – Two sloping sides that meet at a ridge, forming a triangular “A‑frame.”
Hip Roof – All sides slope down toward the walls, with no vertical ends.
Flat Roof – Very low pitch (often < 2°), typical of commercial and modern residential designs.
Single‑ply membranes are factory‑manufactured sheets that are laid in one layer over insulation. The three chemical classes are:
Thermoset (EPDM) – Synthetic rubber, durable and UV‑resistant.
Thermoplastic (TPO) – Heat‐weldable polyolefin membrane, highly reflective.
Thermoplastic (PVC) – Weldable vinyl membrane, chemical‑ and fire‑resistant.
