How To Fix A Leaking Car Roof
Seal That Car Roof Sealant!
It truly is a pain to see the weather cloud up when your car has a leak in the roof. This holds especially true during the rainy or monsoon season. If your car is relatively new and still has a warranty, it would be advised to bring the car to the dealer for proper inspection and factory-warrantied repair.
But for old cars or used cars with no warranty, then a leaking car roof should be given attention immediately. This could lead to more permanent damage such as rust, corrosion, and a foul-smelling interior. Depending on the kind of leak, it could also damage or stain the trim and interior.
When considering how to fix a leaking car roof, the process can be repaired at your own garage with the use of commercially available sealants that block the hole and offer waterproof protection. Why pay money for labor when you can do it yourself, right?
The good news is that you don’t need a degree in automotive engineering to fix a leaking car roof. However, you will need to exercise the right judgment to determine if the problem can be fixed by using sealant alone.
It is best to fully inspect the exterior of your roof and look for cracks or bubbles in the paint. In the case of severely damaged or rusted roofs, a professional garage or workshop should be consulted to solve the problem once and for all.
Repairing The Failed Seam – What You Will Need:
Step 1: Find The Leak
Park the car on level ground and try to find the cause of the leak. Remember that there could be one or more leaks present.
Use a garden hose or small bucket and pour water all over the roof. It would be best to have a friend to help you out while you remain inside the car. This will enable you to find the leak faster. Remove any contaminants and debris such as dust particles, leaves, and small branches on the gutters of the roof.
Leaks are most often present in places where water will usually accumulate. Small cracks, bubbles or rusted parts in the roof can also cause leaks. The part where the windshield meets the roof is most often prone to leaking and rust.
Was the windshield replaced? Was the car repaired (particularly the roof part) due to an accident? Is your car equipped with a sunroof or roof rack? All of these factors might cause a leaking car roof.
When the leak is found, inspect and clear the surrounding area. Wipe with a cotton rag and let the area dry.
Step 2: Apply Sealant
A commercially available roof sealant can easily be bought at the nearest hardware or specialty store (AutoZone, Napa, etc). When learning ways on how to fix a leaking car roof, remember that not all sealants are the same and may vary according to product consistency, packaging, and application. Follow the instructions that came with the product.
Apply a small amount of sealant and use an applicator pad or small piece of cardboard to evenly apply the product and cover the hole. Remember not to put too much sealant in any given area.
After applying the sealant, allow the area to dry for at least 20 to 30 minutes. Use a hair dryer to facilitate the drying process (especially during rainy or cold weather).
Step 3: Test For Leaks
Use a garden hose and test again for leaks, focusing on the part where the sealant was applied. Pat yourself on the back for a job well done if the car cabin remains dry.
Depending on the type of product used, you might either have to repaint or refinish the roof to restore the original appearance. However, this is not a problem if you used a clear-type sealant.
