James N. | Pasadena, CA
“Thanks for all the hard and diligent work your crew did on our roof. I know it was a monstrous feat for your workers as they wrestled with the extreme pitch of the structure.

An Uncommonly Valuable Guarantee


If your new roof starts leaking during the next rainfall, simply give us a call and we will come fix it. No hidden fees or uncomfortable conversations.

What makes this so uncommonly valuable is that our workmanship guarantee lasts up to 10 full years and if you decide to sell your house we will still honor our guarantee (it’s transferrable).

Other roofers have complicated “fine print” guarantees that aren’t worth the paper they are written on because many of them won’t be around 10 years from now! For the last 85+ years we have consistently delivered exceptional quality and we proudly stand behind our workmanship.

Are you looking to save some money?

You might be wondering “could I just get a few repairs instead of replacing my entire roof?”

We answer this question all the time and pride ourselves on providing honest advice so you can weigh your options.

Click the button below and one of our roofing specialists will get in touch with you right away and go through your options so you can decide if you should repair or re-roof.
