We Build Roofs

Their home is most people's’ greatest investment.
Your roof protects your investment... and everything that’s in it.


We build custom roofs because every customer has a custom project. No two roofs are the same. No two customers have the same preferences or the same needs.

We work with you to provide you with the proper roofing materials that suit your project, using only high-quality, high-performance products that will provide years of service in protecting your roof from all of the elements that are constantly at work to destroy it.

All of our roofing products come with long-term warrantees, and on all new roofs that we install we offer a 10 year labor guarantee, so that you know that if you have a problem Certified Roofing will be there, standing behind your roof.

Most people think about their roof only when they experience a problem.
There’s nothing unusual about that.

But your roof is a large part of the appearance of your home, and when you choose Certified Roofing as your builder you will get expert advice on colors, materials, and roofing accessories that will produce a roof that will provide years of trouble free service-- and look great too!


Certified Roofing has a reputation for building quality roofs in the South Bay area, a reputation earned over many years. We are very proud of this.

We realize that our number one obligation is to provide quality workmanship and quality product for our customers, and we take this obligation very seriously. That’s why we use the best people and the best materials when we take on any kind of job. Good products and high quality are our main concerns, and our customers agree that we provide both.
