Best Roofing Companies In Pasadena

“We had a very good experience with Green Ladder Roofing in Sierra Madre. The team was helpful, professional, and easy to work with. I would recommend them for roof repair or roof replacement.😊“

“We had a wonderful experience with Stucco Contractor Pro. Bryan was so responsive to any questions I had throughout the process and the stucco and painting teams were very professional and did beautiful work on our home. Now that the work is complete, we feel like we have a brand new home.“

“Quick responses. Outstanding pricing. Great Warranties. Top notch crews. Highly Recommend.“

“I was very impressed with the quality of work and the friendly professionalism of all the employees at Roof Repair Specialist. Eric came out and gave a thorough estimate to repair the leak on my roof including photos of my roof showing exactly what was to be done. Marvin and Fernando did an excellent job repairing our roof. They took out the old material and installed new underlayment, flashing, and shingles and also sealed and painted the dormers and up vents on the roof. They even cleaned out the gutters! They showed me photos of the completed work. They left everything cleaner than before. Very courteous and professional. Catherine in the office was very timely with her email communications and also sent photos of the work. I highly recommend Roof Repair Specialist! Wonderful job!!“

“Our new roof from J and J is gorgeous and the process was excellent. View of our house from the curb is mostly roof, and J & J guided us to a beautiful and durable total replacement for our 30+ year old roof, choosing not the cheapest, but definitely not the most expensive material: we picked Certainteed Presidential Solaris TL in Country Gray and the result is magnificent.

The communication skills from J and J were exemplary. They have a very accessible-at-all-times boss, Matt, for big strategic questions; then a supervisor, in our case, Justin, who answers more specific questions and figured out the weird tiny details of putting a roof on our eccentric 76-year-old house; then a foreman, actually on the job site, Marco, who has the how-to knowledge and directs the crew. All the workers are employees, not contractors; and they have all the insurance policies, etc. (a lot of formerly local roofers have been bought up by private equity and hollowed out - but not J and J, who are still the real thing, owned locally for decades by brothers Matt and Mike Glass.)

J and J had been doing repairs on our roof for 28 years (always a good job, at a low price) and last fall, this roof was obviously past its useful life. There were four layers on the old one, including shake at the bottom, that had to be torn off; then a new deck built; a waterproof layer; and finally, the new shingles. It was going to be a big job.

Getting a roof is like getting a tattoo — you want to do it right and do it once, because a do-over would be painful and expensive. Over the six months before the new roof we probably exchanged fifty emails with Matt Glass, a process that was extraordinarily helpful. Matt gave us guidance to drive around Glendale, Pasadena and Los Angeles and look at sample roofs in every material, in every color; it was during this run-up that we got a modern roofing education, courtesy of Matt.

We looked at cheaper, functional asphalt shingle roofs; midrange “architectural” shingles; simulated shake and simulated stone made out of concrete and rubber; and so on. We drive a Honda and a Mazda - good-looking cars that will last forever with few repairs, and we wanted to same for the roof. The overlap of durability, beauty and cost guided us to the Certainteed Presidential architectural shingles. Solaris is a “cool roof” legal requirement in the City of LA; and then we paid a little more for the TL (triple laminate) for looks and rock-solid durability.

Tips for when you get a roof replacement: 1. look at and photograph as many sample roofs as you can, that helped us pick the perfect material. 2. demolition is the noisiest, messiest part but only lasts a day or two. Though everything was covered with plastic, roof dust still gets everywhere. Bring inside anything that you can. 3. coordinate with a termite guy - they can do their best work, quickly, when the roof is off! 4. On an old house there will be some small repairs from dry rot or just old wood - just let J & J do the fixes, they did fine job.

They estimated eight days for demo, repair, deck construction, waterproof layer, four ventilation turbines and eight soffit vents, shingles, flashing, etc. and hit the mark exactly.“

“Robert installed our new roof in June 2026. We are very happy! The crew was friendly and efficient, and everything ran smoothly. I highly recommend Lansford Roofing.“

“Clean Initiate Solar installed the solar system at my house. I have an issue where the house battery doesn’t power the house when the grid power goes down, even though the house battery is charged.

The first time I called in, someone answered, and they responded with “we’ll check some diagnostics and call you back in 10 minutes.” They never called, and that was about 3 months ago. I’ve called them and left messages, and emailed, a total of about 20-30 times. They have not answered or respond since the first "we'll get back to you." I will be filing this review in as many forums I can, and with the Better Business Bureau, as a warning to other potential customers.

Update: after posting the review above several places, Clean Initiative immediately reached out, sent out a service tech, and fixed the problem. I'm going with 4/5 stars because there still appears to be no way to reach customer service without going to such drastic lengths, but now I'm happy with the solar installation.“

“SRS Building Products in Pasadena has been a reliable partner for my roofing company's supply needs, their selection of lumber, drywall, and roofing materials is very wide, and the staff are knowledgeable and helpful when you have questions. Pricing is fair and the pickup process runs smoothly. I wish they could open until later hours on saturday“

“If you’re looking for a solar company that has phenomenal customer service, an impeccable work ethic, plus very fair and competitive pricing, look no further! Emin and his crew are outstanding. Emin is extremely knowledgeable, organized and as honest as the day is long. We could not be more pleased with our experience, and would highly recommend this company to anyone considering solar!“
