Why Hire Us?
Ron Williams, "The Roof Doctor" has been involved in the Roofing Industry for over 40 years, and been a Roofing Contractor in business as a Roofing Company (under the same license) for half that time doing roof repair, roof inspection, roof certification and new roofs.
WE COULD NOT CARE LESS ABOUT VOLUME.
When we get more than Ron can do, we stop accepting work.
Ron Williams personally does every single inspection and is present on every single repair job.
At Ron Williams Roof Doctor, We provide the most comprehensive roof inspection available in the area. We also offer roof certification, new roof installation including shingle roof, shake roof, tile roof and flat roof installation as well as new rain gutters.
"No one holds a candle to us when it comes to roof inspections , roof certifications or roof repair."
Our original roofing contractor license number since 1991 is: 628619
Before you hire ANYONE, you should go to the California State License Board website and check the status of their license! Some roofing contractors will go through 4 or 5 licenses, I don't see how, but they do. There are lots of high quality roofing companies out there and some bad ones as well.

When it comes to repairing your roof, NO ONE can touch Ron Williams "Roof Doctor's Roofing Company". We repair lots of Shake roofs, we recently got called out to do repairs on a shake roof that had just been "repaired" by a roofing company the previous year. When we arrived it was obvious why the repairs had failed. Below left are the "shims" the Roofing Contractor had used.
To save money and time, the roofing contractor takes regular shims and splits them
into little slivers. Then because they are so small, as soon as the shims dry a little they
shrink and fall out. To an experienced and ethical roofing contractor, these shims are a joke, and
these consumers and homeowners had been ripped off. Below right are our
minimum
width shims. These two were sold as the same thing, but as you can see it's
not even close.
If you have had a shake roof repair done, do
yourself a favor and check the size of the shims used.
Its easy, mathematically it is impossible to have 1-1/2" coverage on both
sides if the shim is less than 3" wide.

Our "competition?" Ron Williams / Roof Doctor
Our methods for tile roof repair are equally superior.
Unfortunately for consumers, roof repair work is sorely lacking in regulatory standards and consumers are left at the mercy of the roofing contractor or repair person's ethics and experience (or lack of) .
Absolutely there are lots of top notch roofing contractors in the area. We have also found that there are roofing contractors and repair personnel that represent themselves as experienced, without even being aware of basic Roofing Industry Standards and have no or very limited experience in actual roof installation. To be a provider of a roof inspection, roof certification or new roof without meaningful credentials is in my opinion unfair to consumers.
A good example would be the shims in the picture above left. They are too small to comply with minimum coverage requirements set forth by The Cedar Shake and Shingle Bureau. (See line 4 - Shakes shall be laid with a side lap of not less than 1 1/2" between joints in adjacent courses). This is a fundamental practice, and would be second nature to any experienced and ethical roofing company and all of its workers, who would be trained in the installation of shake roofing, shingle roofing and tile roofing at least.
The shims themselves are not as big as the side lap requirement.
At Ron William's Roof Doctor, we throw that size material in the trash.
Having served as a roof installer for over 20 years, a roofing technical
consultant, an expert witness, quality control manager for several large firms
and a 20+ year Roofing Contractor (I know its allot of hats but if you're in
the business this long without different areas of experience you're not
doing anything) Ron Williams is a uniquely
qualified roof inspector, and he will personally do your
inspection.
Coming from a family of roofers, with two brothers, one a Sacramento roofing contractor, one a San Jose roofer, his father, and uncle all roofing contractors, Ron has developed a broad spectrum of roofing experience. The Roof Doctor has the knowledge to diagnose those tricky problems and get the job done right the first time.
"Ron Williams at Roof Doctor is the most knowledgeable roofing
expert I have met in my twenty years of design and construction management. His
trained eye and experience were absolutely invaluable to me when I managed the
reroof of three schools during the summer of 2005. Since then I have relied on
Ron's advice for troubleshooting and managing a variety of roofing projects."
