Here’s what your neighbors say.
Green Ladder is the best roofing company I have ever dealt with! Their project manager Connor signed me up at a very reasonable price and followed up during the entire job, from start to finish.
Green Ladder expertly diagnosed my flat roof leak problems and offered common-sense solutions instead of pushing a full replacement. Honest crew — definitely get a bid from Green Ladder.
From the very first phone call, they made things easy. I was worried about the price, but they helped me find a financing plan that fit right into my budget. The roof looks amazing now, and I can’t stop recommending them to my friends.

Servicing Local Properties With Pride
The crew > the brand
It’s not the shingle.
It’s who nails it down.
Most roof failures come down to workmanship, not materials. Bad nailing, rushed flashing, and missing ventilation are what turn a 30-year roof into a 10-year headache. That’s why who installs your roof matters more than what brand goes on it. It’s also the one part of the job you still get to choose.
As a full-service, BBB-accredited Pasadena roofing contractor, Green Ladder Roofing handles everything from roof replacement and emergency storm-damage repair to new skylights and waterproofing — protecting homes across Pasadena and the surrounding foothill communities.
What actually causes roof failures
GAF Master Elite Contractor
A certification held by only a small percentage of roofers nationwide. It means our installs meet the manufacturer’s highest standards, are backed by stronger warranties, and are inspected for the details that decide how long a roof really lasts.
