Is It Just Me or Do Underlayments Never Last as Long as Promised?

"warranties are great until you actually need them."

Haha, isn't that the truth? Just went through this myself with our first home. Had a similar pitch about "premium" underlayment with some fancy warranty—sounded good at the time. But when we had a leak last winter, surprise surprise, warranty didn't cover it due to some obscure clause about slope angles or something...

Ended up getting a buddy who's handy to help me tweak the flashing and improve attic ventilation. Zero leaks since then, even after some serious downpours this spring. Like you said, getting those basics right seems way more important than any warranty fine print.

Honestly, I've started treating warranties like those extended car warranties—nice idea, but probably not worth the paper they're printed on, lol.

- Totally get your frustration—seen this happen way too often.
- Had a client last year with a similar "premium" underlayment warranty issue. Manufacturer denied coverage due to "improper attic airflow," even though ventilation met local code.
- Ended up redoing the ventilation and flashing myself, problem solved.
- Bottom line: warranties can be helpful, but proper installation and good ventilation usually matter way more than the fine print.

Couldn't agree more. Honestly, I've seen so many "premium" underlayments fail way before their warranty period that I've become pretty skeptical about the whole thing. Usually, it's not even the product itself that's the issue—it's how it's installed or the conditions it's exposed to. My advice: always double-check your attic airflow, flashing details, and make sure your installer knows their stuff. Warranty or not, that's your best bet to avoid headaches down the road...

Good points here, but now I'm wondering—how often do installers actually discuss attic ventilation and flashing details with homeowners beforehand? Seems like that's usually an afterthought until something goes wrong...

In my experience, installers rarely go into detail about attic ventilation or flashing unless the homeowner specifically asks. It's not necessarily negligence—more like a combination of assuming homeowners aren't interested in technical details and trying to streamline the sales process. But honestly, that's a mistake. Proper attic ventilation directly impacts shingle lifespan and overall roof performance, and flashing is critical for preventing leaks around chimneys, skylights, and valleys.

When I meet with homeowners, I make it a point to briefly explain why these elements matter. It doesn't have to be overly technical—just enough so they understand the basics and can make informed decisions. I've found that when people grasp why ventilation and flashing are important upfront, they're more likely to invest in quality materials and installation methods rather than cutting corners.

Unfortunately, you're right that many times these conversations only happen after something goes wrong...usually leaks or premature shingle failure. A little proactive communication could save everyone headaches down the road.
