We just had our house and 1-car detached garage re-roofed this week by Harlan Roofing and I would highly recommend using them for your roofing project.  We got 3 bids and they were right in the middle but checked their Yelp reviews and they were almost all good.  This company is absolutely a professional do-it-right outfit!  From the guys who actually did the roofing work to the Project Manager and Estimator and office staff we were treated with courtesy and professionalism.  They finished 1/2 day earlier than estimated and even worked with us around a rooftop HVAC unit that needed work from an HVAC company.  I strongly recommend Harlan Roofing and would use them again if we sell this house and move to another one here in Sacramento.
