Action

I reviewed the code handbook, consulted with the city building inspector, selected approved underlayment and vent types, and documented compliance in the project log before starting work.

Technical Skills

Explain the process you follow for installing a shingle roof on a steep‑slope house.
Situation

I was assigned a 12‑story residential building with a 30° pitch that required a new architectural shingle roof.

Task

My goal was to install the shingles efficiently while maintaining safety and ensuring a watertight finish.

Action

I began with a thorough safety setup (harnesses, anchor points), installed a high‑quality ice‑and‑water shield along eaves, laid a synthetic underlayment, used a starter course, applied shingles with proper nailing patterns, and added ridge caps, checking alignment at each step.

Result

The roof was completed two days ahead of schedule, passed the final inspection, and the homeowner reported no leaks after the first heavy rain.

Describe a challenging roof repair you completed and the steps you took to resolve it.
Situation

A client reported water intrusion after a recent hailstorm; inspection revealed multiple cracked slate tiles and a compromised flashing on a historic roof.

Task

I needed to repair the damage while preserving the roof’s historic appearance and keeping the homeowner informed of costs and timeline.

Action

I documented each damaged slate, sourced matching reclaimed slates, carefully removed the broken pieces, repaired the flashing using lead‑compatible methods, re‑installed the slates with copper nails, and provided the homeowner with daily progress updates and a detailed invoice.

Result

The repair restored the roof’s integrity, the homeowner praised the craftsmanship, and the roof passed a subsequent water test with zero leaks.
