What It Is

Sunroofs done watertight, the first time.

Adding a sunroof to a vehicle that didn't come with one is precise work — cutting through a roof correctly, sealing it permanently against PNW rain, integrating with the headliner. We install Hollandia systems manufactured by Champion Auto Systems — the same systems used on factory installs for decades. Two main models: the inbuilt 700 IV with integrated sunshade, and the 321 power top-slider for a different install profile.

We measure twice. Cut once. After enough makes and models, removing the parts is second nature.

If your factory sunroof is leaking, sticking, or refusing to close, we also do full repair service — gaskets, motors, drainage, glass, frame work. Often a repair is significantly less than a replacement.

Common Questions

What people ask before they book.

Will it leak?
Not when installed correctly. Hollandia systems include full water drainage management — channels, drain tubes, gasket sealing. We pressure-test every install before returning the vehicle. PNW weather is the test case for everything we install — if it doesn't hold up here, we don't sell it.
How long does the install take?
Most installs: 1–2 business days. Cutting the roof, fitting the system, integrating with the headliner, sealing against water, and testing all takes time we don't compress. Repair work varies — a stuck motor might be hours; a full glass replacement could be a day.
Will it work on my vehicle?
Hollandia 700 IV fits most sedans and SUVs with adequate headliner clearance. The 321 is the alternative for vehicles where the inbuilt system doesn't fit. Tell us what you're driving and we'll confirm fit before quoting.
What about my factory sunroof — repair vs replace?
Depends on what's wrong. Common repairs: gasket failure (water leak), motor failure, broken glass, broken slide mechanism, drainage clog. Most are significantly cheaper than a full replacement. We'll diagnose and quote both repair and replacement options so you can decide.
Will the sunshade still slide manually if the motor fails?
On Hollandia 700 IV, yes — the integrated sunshade is manual. Even if the sunroof motor fails, you can still control sunshade position. The 321's external slider is power-only.
Can the glass be tinted?
Yes — sunroof glass can be tinted with our standard window tint service. Common request: match the tint level of your other windows for a cohesive look.
