Bay 101 Roofing, Inc., Alviso CA. This is our second home Bay 101 Roofing has re-roofed. Both homes were estimated by Dave Imhof, he goes over every detail for the estimate and answers all our questions and concerns. The first was a rental home, 3000 square feet, with lots of dry rot, a leaking flat top family room addition and a gabled second story roof. There were many roof repairs they had to do before the actual roof was put on. The flat roof was very challenging and Jose came up with a solution that is still working, no leaks. Jose is truly a problem solver. The end project was a complete new roof, new gutters, down spouts. I highly recommend working with Jose, owner, and Dave Imhof, estimator. For the second home, our own residence, we did not even get a second estimate. We just left it up to Dave and Jose. This home is 3800 square feet with a detached garage. The house has many gables, valleys, high peaks. From our rental property experience we knew Bay 101 could do this job. They removed the old wood shingles and replaced with GAF 50 year Glenwood shingles. They added O’Hagen vents for proper ventilation in the two separate attics and installed two new quieter roof ventilation fans. Everyday the crew cleaned up completely, including the two attics, put everything into their own dumpster. They have their own conveyer belt truck to lift materials to the top of first and second stories of house. The roof inspector came while they were working and he told us he is impressed seeing them work and the equipment they have. There was one little problem in the attic and I called Lorena and she had them out to fix it in two hours. They also added O’Hagen vents to the detached garage and the garage is cool even in this hot weather. We highly recommend Bay 101 Roofing Co and Jose, Dave, Lorena and crew.

Review by in San Jose, CA
Five stars all around. Jose and his crew did an excellent job. Kept me informed all way, and went above and beyond to make sure I was satisfied with the final result. This is a quality company and should not be overlooked when considering a roofing contractor.

timely estimate, prompt temporary fixing of roof, started roof early and complete on time, cleaning after as if they were never there for 2 days. They have own dump truck, auto conveyer to move all material onto roof, auto gutter/spout cut to exact length; crew were on time, diligent, no slacking when boss is not present.

Bay 101 Roofing was punctual, well prepared with documentation pertaining to the company, copy of liability insurance, diamond certified award and referrals. Michael Hunt took the time to explain available options and review areas of current and potential problems.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
