The Truth About Soldering in Metal Roofing

Hey ASM101 Crew,

Let’s talk about soldering—the so-called gold standard of metal roof sealing. 

For years, it’s been viewed as a badge of honor, a sign of true craftsmanship. But is it really the best solution in today’s industry?

In our latest deep dive, "Soldering Explained," we break down where soldering shines, where it falls short, and why some of the best in the trade are moving towards more efficient, longer-lasting techniques.

🔑 Key Takeaways:

✅ Soldering Isn’t Always King – While it’s reliable, it’s expensive, skill-intensive, and limited to certain materials like copper and galvanized steel. For pre-painted metal? Forget it—you’re voiding warranties.

✅ A Dying Art? – The trade is shifting. Modern European folding techniques and high-end sealants can create watertight, durable joints without the need for flames or solder sticks.

✅ Leveling Up Your Craft – Moving beyond soldering forces you to become a better tradesperson. Learning how to use concealed sealant applications and advanced folding means fewer callbacks and longer-lasting roofs.

🚀 What This Means for You

If you’re still relying on soldering as your go-to, it might be time to rethink your approach. New methods are faster, safer, and just as effective—if not more.
