YEARS OF EXPERIENCE AS ONE OF THE MOST RELIABLE ROOFING COMPANIES IN SIMI VALLEY, CA
Simi Valley’s extreme heat and seasonal winds can cause roofing materials to degrade prematurely. Our inspection and maintenance programs are designed to identify “shingle uplift” and debris buildup before they turn into major leaks. We provide thorough checks of flashings, valleys, and gutter systems, which are vital for homes near the heavily wooded areas of Big Sky and Wood Ranch. By identifying minor issues during an annual inspection, we can often address them before they develop into more serious and costly problems. For details or for questions about the GreatWay Roofing Inspection and Warranty program, please call our office at 805-523-2550.
We conduct our Simi Valley Roofing business in a manner that elevates how roofing contractors are perceived by individual homeowners and commercial clientele alike. Customer service is paramount at GreatWay Roofing Company.

Why Regular Maintenance is Vital for Your Roof’s Lifespan
Think of roof maintenance as preventative care for your largest investments. Just as you wouldn’t drive a car for 50,000 miles without an oil change, your roof requires professional oversight to withstand the Simi Valley climate.
-
Preventing Tile Failure: In Simi Valley, high winds often cause tiles to shift, break, or even fall off the roof. When a tile moves, it exposes the sensitive underlayment to the sun and rain, which leads to premature leaks and costly repairs.
-
Avoiding Composition Shingle Damage: Strong winds and intense sun exposure can cause composition shingles to lift, crack, or lose their protective granules. When shingles become loose or deteriorate, the underlayment and roof deck are exposed to moisture, increasing the risk of leaks, wood rot, and interior damage. Addressing minor issues early helps prevent widespread failure and extends the life of your roof.
-
Validating Your Warranty: Most roofing manufacturers and workmanship warranties require regular, documented inspections to remain valid. Our program provides the historical records you need to keep those protections in place.
-
Proactive Debris Management: For homes in Big Sky and Wood Ranch, debris from local trees can trap moisture and accelerate material rot. While we no longer promote gutter cleaning as a standalone service, we include debris removal from the roof and gutters as a standard part of our maintenance package.

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
