Project #3572: 2003 Tiffin RV Roof Reinforced for the Road Ahead

Breathing New Life Into a 2003 Tiffin Motorhome Roof

Mark’s motorhome was built in 2003—but you wouldn’t know it by looking at the roof today.

When he decided to tackle his aging Tiffin motorhome’s roof, Mark didn’t want to settle for short-term fixes or temporary patch jobs. Instead, he turned to Crazy Seal for a seamless, long-lasting solution he could install himself. With a solid fiberglass base and an older CSL 515 sealer in place, Mark was ready for a transformation that would make his 20-year-old rig road-ready again.

And that’s exactly what he got.

After applying two full coats of the Crazy Seal system across the entire roof, Mark created a fully sealed, cohesive barrier from corner to corner. No cracks. No gaps. No leaks. Just confidence in a roof that’s ready to handle anything the weather throws at it.

From Aged to Armor – A Fiberglass Roof Reimagined

Many RV owners might wonder whether a product like Crazy Seal is necessary for a fiberglass roof. Mark’s project is proof that it absolutely can be.

By applying the Crazy Seal system over his existing fiberglass, Mark essentially added an extra layer of protection—one that moves with the roof, flexes with travel, and stands up to both time and temperature. What used to be a tired, worn surface is now a bright, reinforced barrier that looks as clean as the day the RV rolled off the lot.

Better still, it’s a DIY win.

With no special equipment or professional crew required, Mark was able to install the entire system on his own, guided by the support materials and confidence that come with Crazy Seal’s 50-year warranty.
