SIMI VALLEY ROOF REPAIRS / INSTALLATION REQUIREMENTS
What You Need to Know for Your Next Roofing Project in Simi Valley
When you start a new residential or commercial roofing project in Simi Valley, understanding the local permit requirements can save you significant time and money.
The 100-Square-Foot Rule: In the City of Simi Valley, a building permit is typically not required for roof repairs or replacements involving less than 100 square feet of material within any 12-month period. This is a major advantage for our customers, as it allows GreatWay Roofing to address minor leaks and maintenance issues immediately without the delays or costs of the city permit process.
Permits & Inspections: For larger projects exceeding 100 square feet, a permit from Building & Safety is required. This process ensures your safety through two key inspections:
- Roof Deck (Nailing) Inspection: Performed after the old material is removed to verify the deck integrity and nailing pattern.
- Final Inspection: Completed after the new roof is installed to ensure full code compliance.
While the city follows California’s Building Code, many Simi Valley neighborhoods have specific HOA restrictions regarding material types and colors. We recommend checking with your HOA or contacting Simi Valley Building & Safety at (805) 583-6723 before finalizing your material choice.
Why Your Simi Valley Roofing Contractor Matters
By law, California roofing contractors must provide specific protections for the property owner. When reviewing your GreatWay contract, you will find:
- Verified Licensing: Our standing with the California Contractors State License Board (CSLB).
- Full Insurance Coverage: Proof of General Liability and Workers’ Compensation.
- Consumer Protections: Required notices, including the “Notice to Owner” and “Checklist for Homeowners.”
- Clear Project Terms: A specific scope of work with estimated start and completion dates.
- Fair Payment Terms: We strictly follow the law—deposits never exceed 10% or $1,000.
- Comprehensive Warranties: Detailed information on both Workmanship and Material warranties, including specifics—vital for the Simi Valley climate.
- Local Accountability: A physical business address (not a P.O. Box) and a list of local Simi Valley references.

REVIEWS
WHAT OUR CLIENTS ARE SAYING
Tim and Brandon sent updates at every step including pictures of their work in real time.
We are very pleased and have contracted them for another property.
Highly recommend.
The price was great (as much as it can be for a roof, no small purchase), and the crew was really fantastic. They were professional and got the work done quickly. They had to put sheathing on my roof, since it’s old and didn’t have any underneath (!), and the whole project still only took 4 days.
For me, the best thing was that the crew cleaned up every day. The yard was clear, and there were no nails or debris hanging around. It’s a little thing that was really nice to see— it was really nice to go outside in the afternoon and not worry about stepping on anything/ having that peace to move around in the middle of a project.
I’d recommend this company to anyone.
This company is a class act and I am so pleased to have picked GreatWay Roofing who kept me informed thru email and sent photos as the project was moving ahead.
Great customer service, knowledgeable courteous workers and a satisfied customer says it all
