ZOMBIE ROOF EXAMPLES: A FIELD GUIDE
A 'zombie roofer' isn't necessarily a bad person; they are a symptom of a broken system where crews are often uninformed about proper techniques and local codes. This gallery contains real-world intel of common, costly mistakes our operatives find in the field. Use this guide to learn what to watch out for.
Exhibit A: Mismatched Underlayment
The roofing crew ran into an issue and, instead of getting the correct materials, they used generic felt from their van. There is no manufacturer warranty for shingles unless you also use the same brand for your felt. This crew planned to void the warranty from the start.
Exhibit B: Roofing Over Old Felt
This crew was about to install new felt directly over the old, torn layer. This violates building codes and, more importantly, prevents a proper inspection of the wood decking for rot or damage. These aren't bad guys, just zombies—doing without knowing.
