Yes, you can add a sunroof to almost any car, provided the roof is flat enough and lacks structural bracing that cannot be moved. Most installations involve cutting the sheet metal, installing a reinforced frame, and fitting a glass panel with weather-sealed gaskets. While possible for most sedans and SUVs, the process requires professional tools to ensure the car remains leak-free and safe.
Adding a sunroof is a major modification that changes your car’s look and feel. Whether you want a simple manual pop-up or a powered aftermarket panoramic sunroof, understanding the technical side is key. At Texas Reliable Auto Glass, we see many drivers wanting that open-air feeling, but it is important to know how it affects your car’s structure and value before you cut it.
What Does It Mean to Add a Sunroof to a Car?
Adding a sunroof means installing an aftermarket unit into a vehicle that did not come with one from the factory. It is not the same as a factory-fitted sunroof, which is built during manufacturing and is part of the car’s original design.
Here is how the process actually works:
A technician traces a template on your roof to mark the exact cut zone. Then a power tool cuts through the sheet metal, following that template precisely. The headliner, which is the fabric ceiling inside your car, is trimmed and modified to fit the new opening. A metal frame is dropped into the hole and bonded to your roof. The glass panel is then fitted into that frame and sealed with weatherstripping. Finally, drainage tubes are routed from each corner of the frame down through your door pillars to carry rainwater safely out of the vehicle.
That drainage system is the most important part of the whole job. Skipping it or routing it wrong is the number one cause of water damage after aftermarket sunroof installs. A clean installation should leave zero gaps between the seal and the metal.
Pro Tip: Always ask your installer how they route the drain tubes before work begins. If they cannot explain it clearly, find another shop.
Is It Safe to Add a Sunroof to a Car?
This is what most drivers ask first. Your car’s roof is part of its safety cage. It keeps the cabin intact during a rollover. Cutting into it sounds risky, and it can be if done by the wrong hands.
Here is the reality though. A professional installation is safe. Certified technicians avoid cutting the main structural beams of your vehicle, called the A-pillar and B-pillar. These are the steel bones that hold your roof together. As long as those stay untouched, your car’s crash protection does not change in any meaningful way.
The glass itself is also engineered for safety. Every sunroof uses tempered or laminated glass. This means it breaks into small, blunt pieces rather than sharp shards. It works on the same principle as your windshield.
Warning: A cheap or uncertified shop may cut into a support beam to save time. This weakens your roof and puts you at real risk in a crash. Always choose a shop with verifiable experience and documented installs.
One more thing worth knowing. Some modern vehicles have sensors, wiring, or rollover protection systems built into the roof structure. Tell your installer this before any cutting starts. Those components need careful handling.
Understanding Different Types of Sunroofs
Not all sunroofs work the same way. Each type comes with different costs, installation time, and impact on your car’s headroom. Here is a breakdown of every option available.
Pop-Up Sunroof
This is the simplest and most affordable type. The glass tilts up at the rear to let air in. On some models, you can remove the panel entirely on sunny days. It does not slide back into the roof. This works well for small cars or drivers on a tight budget.
Spoiler Sunroof
A spoiler sunroof tilts and then slides back over the top of the roof rather than inside it. This design preserves interior headroom. It is one of the most popular choices for aftermarket sunroof installs because it is less invasive than inbuilt models.
Inbuilt Sliding Sunroof
This is the type that looks factory-installed. The glass slides between the metal roof and the headliner. When fully open, it disappears inside the ceiling. This takes more labor and costs more, but the finished result looks completely clean and professional.
Aftermarket Panoramic Sunroof
An aftermarket panoramic sunroof covers a large portion of the roof with glass. It makes the cabin feel open and bright. These are complex to install because they require more cutting, more sealing, and often structural reinforcement. They are the most expensive option, but also the most dramatic upgrade you can make to your car’s interior feel.
A common question is whether a panoramic sunroof opens. Most aftermarket panoramic units have at least one panel that tilts or slides. Some are fixed glass only. Confirm this detail with your installer before you commit to a unit.
Folding Fabric Sunroof
Folding sunroofs use canvas or vinyl instead of glass. The material folds back when open. These are lighter and cheaper than glass options and suit classic or vintage cars well. They cost less but do not last as long and offer lower weather resistance than solid glass panels.
Sunroof Type Comparison
Type | Cost Range | Install Time | Headroom Loss | Best For |
Pop-Up | $800–$1,200 | 4–6 hrs | Minimal | Budget buyers |
Spoiler | $1,000–$2,000 | 6–8 hrs | Very Low | Compact cars |
Inbuilt Sliding | $1,500–$3,000 | 8–12 hrs | 1–2 inches | OEM-style look |
Panoramic | $3,000–$5,000 | 2–4 days | 2–3 inches | Luxury feel |
Folding Fabric | $700–$1,500 | 4–6 hrs | Minimal | Classic/vintage |
Sunroof vs Moonroof | What’s the Difference?
People use these two words like they mean the same thing. They do not.
A sunroof is a solid or glass panel that opens, tilts, or can be fully removed. Early sunroofs were often metal panels that you would pop out and store in the trunk.
A moonroof is always made of tinted or clear glass. It slides open or tilts but always has a built-in interior shade. When the glass is closed, you can still see the sky by pulling back that shade. Most modern vehicles sold today actually have moonroofs, not sunroofs.
For aftermarket installation, the terms are often used together. When most people ask can you add a sunroof to a car, they usually want a sliding glass panel with an interior shade. That is technically a moonroof, but any good installer will understand exactly what you mean.
Quick Fact: Moonroofs became the standard after Ford popularized the tinted glass design in 1973. Today, over 40% of new vehicles come with one from the factory.

Cost Analysis: Breaking Down the Prices for Each Sunroof Type
Cost depends on three things: the type of sunroof you choose, your car’s roof shape, and the shop’s labor rate. Here is what you should expect to pay.
Pop-Up Sunroof: $800–$1,200 This price includes parts and labor. Installation takes 4 to 6 hours. The low cost comes from the simple mechanism. There are no motors, no hidden tracks, and no major headliner modification needed.
Spoiler Sunroof: $1,000–$2,000 The sliding mechanism adds cost over a pop-up. An electric model adds $300 to $500 to that range. Labor runs 6 to 8 hours. Manual crank versions keep the price lower.
Inbuilt Sliding Sunroof: $1,500–$3,000 This type requires full headliner work and a hidden track system. Premium UV-coated glass adds to material costs. Labor runs 8 to 12 hours. The higher cost reflects the cleaner finish.
Aftermarket Panoramic Sunroof: $3,000–$5,000 Panoramic sunroof installation is a full-day or multi-day job. Structural reinforcement may be needed depending on your vehicle. Multiple glass panels require precise alignment. A 2-year parts and labor warranty from a certified shop is worth every dollar here.
Folding Fabric Sunroof: $700–$1,500 Fabric models cost less than glass. Installation time is similar to a pop-up. The lower price point makes these popular for budget builds and older vehicles.
Other factors that affect your final cost:
Curved roofs cost more to modify than flat ones. Luxury vehicles need specialized fitting kits. UV-coated or tinted glass adds $100 to $300. Auto-closing sensors or rain detectors add $150 to $400. Extended warranty coverage adds $100 to $300 but protects against leaks and motor failure down the road.
Does a sunroof add value to a car? It can. Buyers who specifically want one will pay more for a vehicle that has it. The key is professional installation backed by receipts and warranty documentation. That is what actually holds resale value. A poorly installed sunroof does the opposite.
Signs of a Bad Sunroof Installation
This section is missing from most guides, but it is one of the most useful things to know. Here is how to spot poor workmanship before you drive away from the shop:
Water drips inside the car during a hose test. Any good shop will do this test before handing back your keys. The glass sits unevenly in the frame. Any visible gap between the glass and the seal is a red flag. Wind noise at highway speeds that was not there before means the seal is not flush with the roof. The headliner has wrinkles or bubbles near the opening, which signals rushed interior work. The drain tubes are not explained or visible. Ask to see exactly where they exit the vehicle. Rattling when you hit bumps means the frame is not fully secured.
If you notice any of these issues, do not accept the vehicle. A professional installer will fix them before you pay. Anyone who tells you these things are normal is wrong.
Factors to Consider Before Adding a Sunroof To a Car
Vehicle Age and Condition
Older cars may not justify the investment. If your car is worth $5,000 and the install costs $2,000, think it through carefully. Also, rust around the roof complicates installation significantly. Fix any rust or body damage before any sunroof work begins.
Headroom
Inbuilt and panoramic sunroofs reduce interior height by 1 to 3 inches. Tall drivers need to account for this. Spoiler sunroofs preserve the most headroom since the glass slides over the roof rather than inside the ceiling.
Texas Heat and Its Impact on Seals
This is something most guides skip entirely, but it matters for every Texas driver. In Austin, summer temperatures regularly hit 100 degrees or more. That level of heat dries out rubber weatherstripping far faster than in cooler climates.
Dried seals crack. Cracked seals leak. A sunroof that was perfectly installed in April can start letting water in by September if the seals are not maintained. Use a silicone-based lubricant on your seals every 3 to 4 months. Clean the drain tubes every 6 months to remove dust and debris before they build up into a clog.
Texas Driver Tip: Park in shade whenever possible and use a sunshade when parked outdoors. Direct sun exposure speeds up seal degradation and can warp the plastic trim around the sunroof frame over time.
Insurance
Check with your insurance provider before you modify your roof. Some policies do not cover damage related to aftermarket modifications. Others require you to notify them of any structural changes to the vehicle. A quick call before installation could save you thousands later.
Cars That Cannot Get a Sunroof Added
Some vehicles should never have an aftermarket sunroof installed. Convertibles already lack full structural roof support, so adding a sunroof makes them dangerous. T-top and targa top cars are engineered for removable panels only. Vehicles with existing moonroofs should not get a second opening. Cars with serious roof rust or prior collision damage need those problems fixed before any cutting takes place.
Electrical Compatibility
Power sunroofs need a dedicated circuit. Older vehicles may need wiring upgrades to handle the extra electrical load. Improper wiring causes shorts and can damage your car’s electronics. Ask your installer specifically how they plan to route and protect the new wiring before they start.
Warranty Status
If your car is under a manufacturer’s warranty, read the fine print. Some warranties are voided by structural modifications to the roof. Get written confirmation from your dealer before you move forward. For vehicles under third-party extended warranties, check the modification clause carefully before you commit.
Ongoing Maintenance
Clean your drain tubes every 6 months. Leaves and debris clog them and cause interior flooding. Lubricate the tracks and seals every 3 to 4 months with silicone spray. Inspect the glass and frame after any major hailstorm. If the motor slows down or starts skipping, get it checked before it stops working completely.
Final Thoughts
Adding a sunroof is one of the best upgrades you can make to a car when it is done right. You get more light, better airflow, and a cabin that feels completely different from the moment you open it. But the quality of the work matters more than anything else. A cheap install leads to wet seats, interior mold, and rust repairs that cost far more than you ever saved upfront.

FAQs
Can you add a sunroof to a car without voiding the warranty?
It depends on your warranty. Most manufacturer warranties do not cover modifications to the roof or headliner. They usually do not affect the engine or drivetrain warranty though. Always check with your dealer before making any structural change.
How long does sunroof installation take?
A basic pop-up takes 4 to 6 hours. A power inbuilt sunroof takes 8 to 12 hours. A panoramic system can take 2 to 4 days. Plan to leave your car at the shop for at least a full day.
Will an aftermarket sunroof leak?
Not if it is installed correctly. Most leaks come from poor sealing, missing drain tubes, or clogged drainage channels that were never maintained. Regular upkeep prevents nearly all water issues.
Does a sunroof add value to a car?
It can. Buyers who want a sunroof will pay more for a vehicle that has one. Professional installation with receipts and warranty paperwork is what makes that value stick.
Can I install a sunroof myself?
It is not a good idea. You only get one chance to cut the roof metal. A mistake is expensive and sometimes impossible to fully correct. The tools needed for proper sealing and drain routing are specialized. Leave this to a professional shop.
What is the difference between an aftermarket panoramic sunroof and a factory one?
Factory panoramic sunroofs are engineered into the vehicle’s structure from the start. Aftermarket versions are cut into an existing roof. Both look similar, but factory units are integrated more precisely. Aftermarket panoramic sunroof installation requires structural reinforcement to compensate for the larger opening.
What cars cannot have a sunroof added?
Convertibles, T-top cars, targa tops, and vehicles with existing moonroofs should not have an additional sunroof installed. Vehicles with significant roof rust or collision damage are also poor candidates until those problems are repaired.
