Need advice on replacing an old leaky roof

"Don't skimp on fasteners. Seen too many roofs fail early because someone went cheap on nails or screws."

Couldn't agree more—fasteners seem minor, but they really matter long-term. I recently built my first custom home and went with peel-and-stick membranes around dormers and valleys. Installation was straightforward, and so far, no leaks even after some heavy storms. A bit pricier upfront, but the peace of mind is worth it for those tricky areas.
