Underlayment is the layer nobody sees and the one that keeps the house dry while the roof is open. Once the old material is off and the deck has been repaired, the field is dried in before anything else happens, working from the eave upward so each course laps over the one below it and water can only run outward. Laps are set to the material's own overlap, not eyeballed. It carries around penetrations and up wall lines, where it is later locked in by formed metal. The finish material goes over the top of a surface that would already shed water on its own. That order is the difference between a roof and a covering.

Roofing in Simi Valley is estimated after an inspection, never before one. The onsite visit is free and produces a detailed scope of work and a remodeling consultation, covering the roof system, the underlayment, the flashing schedule and where water leaves the building. That document is what a price is built against. Permits belonging to the work are prepared and submitted by MyCali Builders. The company is licensed and insured, carries CSLB #1072368, and has been in business since 2020. Financing is available, and the completed roof is covered by a warranty of 5 years.

I recently hired My Cali Builders for a backyard remodel and couldn't be happier. Danny and his team were professional, punctual, and easy to communicate with. They really paid attention to the details and brought my vision to life. The quality of the work exceeded my expectations from start to finish. Everything was done cleanly and on schedule, which I really appreciated. Danny made the whole process smooth and stress-free. The backyard now looks amazing and feels like a completely new space. I would definitely recommend them to anyone looking for reliable contractors.

I began my Yelp search for a company to perform structural repairs and ultimately chose 5 companies, scheduling each of them for a representative to visit and discuss my needs. I chose My Cali Builders based upon Danny's (owner) review of the work and how he defined the scope of the work. The other representatives vacillated on the scope of the work and attached various caveats. My Cali Builders also gave me the best bid. So I hired them and boy, am I glad I did. Work was performed quickly, efficiently and the finish work was excellent. Every task I initially discussed with Danny was completed. Danny's crew including Francisco and Jaime, were top notch and pleasant. Each day, refuse and trash were removed. Every day, Danny either visited or texted to advise on progress and to insure the work was progressing as discussed and to ask if I was satisfied and happy. I can't convey in words how much I appreciated My Cali Builders. Look no further, they are the best I've ever encountered.

Danny Raz is a man of action; the work was done promptly and even finished ahead of schedule. The workers were polite, respectful, of cleaned up well after the job.

FAQs

Roofing in Simi Valley - common questions

Answers to the most common questions about this service in your area.

Yes. We have completed multiple Roofing projects in Simi Valley. Call (310) 220-0903 to schedule a free onsite visit, or compare public feedback on the customer reviews page.

Duration is set at the estimate, once the roof size and the system are known, and it is written into the scope rather than promised beforehand. The stages themselves are fixed: strip to the deck, repair sheathing, dry the field in with underlayment, form the flashing, lay the finish material, finish the drainage, then clean the site and walk it.

Permits are required for full roof replacements in most cities. We pull the permit and schedule the required inspection before work closes out. You can also step back to the main Simi Valley page to compare related local services.

Roofing is not quoted from a rate sheet in Simi Valley. Roof area, pitch, the number of layers coming off, how much sheathing turns out to be soft, the flashing schedule and the finish system all set the number, and none of them can be judged from a photograph. The onsite visit and the estimate are free, and the figure is calculated from the written scope of work.
