“Water’s sneaky, finds the tiniest gap.”
That’s the truth—water will always find a way, especially after a freeze-thaw cycle. I’ve seen plenty of cases where folks thought a bead of caulk would do the trick, but unless every seam and penetration is sealed perfectly (and stays that way), it’s just a matter of time before moisture gets in. Caulk can shrink or crack with temperature swings, too, so it’s not always a long-term fix.
Doubling up on ice and water shield over low-slope areas is a solid move. Those spots are notorious for leaks because water doesn’t run off as quickly, and snow tends to linger. I’ve inspected roofs where the only dry section was the one with extra underlayment—definitely worth the upfront cost if you’re already dealing with patch jobs every spring.
About ice dams on north-facing roofs: you’re not imagining things. North sides get less sun, so snow and ice stick around longer. That means more freeze-thaw cycles and more chances for dams to form. I’ve seen some homeowners try heat cables or extra attic insulation to help, but results vary depending on roof design and ventilation. Sometimes it’s just the nature of the beast in colder climates.
Cost-wise, yeah, it stings. But like you said, patching every year adds up—not just in money but in time and hassle. If you’re already seeing drips in the attic, it might be worth looking at a more permanent solution before things get worse. Water damage inside can get expensive fast.
One thing I’d add: check your attic ventilation while you’re up there. Poor airflow can make ice damming worse by letting heat build up under the roof deck. Sometimes a few extra vents or baffles make a surprising difference.
Hang in there—it’s frustrating, but catching these issues early is half the battle.
