About Roger Zona
(Top Expert on this page)

Expertise
I am experienced in all types of construction: residential, industrial and commercial; single family, multi-family, mid-rise and high rise buildings (16 story) as well as remodeling, additions and tenant improvements. I can field most any question that relates to general construction. I have consulted with infrastructure (utility) contractors also and have a good general knowledge of underground utility construction for subdivisions and commercial projects.

Experience
After college, I began my career in automotive engineering. After 4 years I chose to become an apprentice Architect; 4 yrs later I opened my own architectural firm. Six years later I moved to Florida to buy & develop land and build. I became a State Certified General Contractor and operated my business for 40 years. I built all types of residential and commercial buildings including warehouses, shopping centers, high rise apartment and office buildings and developed sites for other contractors. I retired and became a consultant to the construction industry. I maintain my license and continuing education requirements, operate a small construction company and write a weekly newspaper column for the Palm Beach Post (a Cox publication) with the byline "Ask The Contractor". I am the "technical editor" for a publisher of books that relate to home maintenance.

Publications
Palm Beach Post newspaper

Education/Credentials
BS in Engineering
