Protect your investment with a documented commercial inspection and maintenance program. We provide the regular oversight needed for properties, including on Tapo Canyon and Madera Street, and surrounding business parks. Our programs focus on clearing drainage systems and checking for wind-related membrane lift, ensuring your facility is prepared for both high heat and heavy rains. Regular maintenance helps ensure that any necessary work stays within the 100-square-foot permit-free threshold, avoiding the cost and time associated with full city permits for minor upkeep.
Commercial Project Tip: While many minor repairs under 100 square feet do not require a permit in Simi Valley, a full commercial re-roofing project involves a multi-stage inspection process with the city. We handle the entire permitting and inspection workflow to ensure your building meets current safety and Title 24 energy codes. You can view the full

Maintenance to Protect Your Warranty
Ongoing maintenance is not just a recommendation; it is a critical requirement to keep both workmanship and manufacturer warranties valid. Without documented professional oversight, many manufacturers may deny claims related to material failure.
-
Preventative Sealing of Critical Points: We don’t just look for leaks; we actively reseal pipes, vents, and other penetrations as part of our preventative process to stop water before it enters the building.
-
Scheduled Oversight & Strategic Planning: Depending on the age and material of your roof, we advise professional inspections every one to two years. This allows for a “maintenance as needed” approach, preventing the compounding damage caused by long-term exposure to Simi Valley’s UV and wind.
-
Documented Inspection Reports: Our maintenance program includes a detailed report and cleaning. This documentation is vital for property managers to prove due diligence to insurance carriers and owners, ensuring minor issues never evolve into expensive emergency repairs or total roof failures.
-
Long-Term Cost Mitigation: By identifying and addressing small repairs—often those that fall under the 100-square-foot permit-free threshold—we extend the service life of your roof by years, delaying the massive capital expenditure of a full re-roof.

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
