Expert Residential Roof Leak and Damage Repair in Simi Valley
If your roof has been damaged by high winds or age, prompt repair is essential to prevent water intrusion. Since 1999, GreatWay Roofing has been the trusted name for homeowners throughout Simi Valley seeking honest assessments and high-quality craftsmanship.
Why Early Roof Repair is a Smart Investment
A small leak in your ceiling is often the final stage of a problem that started months ago. Our goal is to catch these issues early to save the structural integrity of your home.
-
Preventing Structural Rot: Constant moisture from even a minor leak can lead to wood rot in your rafters and decking, which significantly increases future repair costs.
-
Protecting Insulation: Once attic insulation gets wet, it loses its “R-value” (insulating power) and can quickly become a breeding ground for mold.
-
Preserving Curb Appeal: We take pride in our “invisible” repairs. Whether it is a specific tile profile or a unique shingle color, we match your existing materials to ensure your roof looks seamless.
Wildfire Preparedness: Vulcan Retrofit Vents
If you aren’t ready for a full re-roof but want to protect your home from wind-driven embers, we specialize in Vulcan retrofit dormer vents. These are specifically designed to replace your existing, vulnerable attic vents with fire-safe technology that “hardens” your home against wildfire risks without requiring a full system replacement. (Note: For those undergoing a full re-roof, we recommend the O’Hagin Fire & Ice® low-profile vents for maximum protection).
Simi Valley Expert Tip: The 100-Square-Foot Rule
In the City of Simi Valley, a building permit is typically not required for roof repairs involving less than 100 square feet of material within any 12-month period. This allows GreatWay Roofing to respond quickly to small leaks, missing shingles, or minor tile damage without the administrative delay of a city permit. For larger projects that exceed this limit, you can view the full

Common Simi Valley Roof Repairs We Handle
The Simi Valley corridor experiences intense heat and seasonal winds that can compromise even the best-installed systems.
- Valleys: Debris buildup can block drainage paths, forcing water under shingles and into weak points, resulting in leaks and long-term roof damage.
- Flashing: Damaged or deteriorated flashing allows water to penetrate vulnerable areas of the roof, leading to leaks and potential structural damage.
- Shifted & Cracked Tile Replacement: High winds and heat can cause tiles to move or break. We re-secure shifted tiles and replace cracked ones to prevent underlayment failure.
- Wind-Blown Shingle Repair: After a Santa Ana wind event, shingles can be uplifted or blown off entirely, leaving your home exposed.
- Vent Cap Stabilization: Vent caps are highly susceptible to wind damage. We ensure these critical areas are properly secured and sealed.

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
