# John V. Roy

## The honest read

John V. Roy is an electrical contractor listed in Rockland, and the BuildZoom profile for the business names Cristiano Da Silva as its owner.

What BuildZoom carries is a permit trail and a licence block. The permits are a pair from 2013 — one building, one electrical — for a kitchen and bathroom remodel at a house on James Avenue in Nahant, alongside one sample project and a BZ Score of 90. The licence block lists several Massachusetts numbers tied to the name: an electrical business licence #8400, plumber and master plumber numbers, and a sheet metal licence #4922.

For electrical work at a house, the useful first call is a direct one: ask which licence the person doing your job holds, and for a recent job like yours you can look at.

**Strengths:**
- Permitted remodel work — 2013 building and electrical permits in Nahant
- BuildZoom score 90 — on the Rockland electrician profile

**Where sources disagree:**
- BuildZoom lists the business under the name John V. Roy while naming Cristiano Da Silva as its owner.
