Why Nassau County Homeowners Choose Roth

Nassau County sits over Long Island's sole-source aquifer. Protecting your home and your community's drinking water starts with the right oil tank.

Double-Wall Leak Protection

The galvanized steel outer shell holds 110% of the inner tank's capacity. If the inner HDPE tank ever fails, the outer wall catches every drop. A built-in optical alarm alerts you immediately. No oil reaches your floor, soil, or groundwater.

30-Year Manufacturer Warranty

Every Roth tank is backed by a 30-year limited warranty covering manufacturing defects. Steel tanks typically carry a 5- to 10-year warranty and start corroding from the inside within the first decade.

$2 Million Environmental Insurance

Roth includes 10 years of environmental coverage: up to $2 million for cleanup costs and $2 million for property damage per occurrence. Standard homeowner policies exclude oil spills under the pollution exclusion clause.

Zero Corrosion Risk

The seamless blow-molded HDPE inner tank cannot rust, pit, or corrode. Steel tanks develop internal pitting within 5 to 10 years from condensation and microbial acid. The Roth inner tank is completely immune to these problems.

Nassau County Oil Tank Regulations

Residential heating oil tanks under 1,100 gallons are not regulated by New York State Petroleum Bulk Storage (PBS) rules. However, the Nassau County Department of Health has delegated authority from the state and may apply additional local requirements for oil storage tanks.

Here is what Nassau County homeowners should know:

  • Old tanks must be emptied, cleaned, and purged of all vapors before removal per NYS law
  • Underground tank removal requires the vent and fill lines to be removed or the fill line capped with concrete
  • Aboveground double-wall tanks are strongly recommended by county officials and insurers over underground and single-wall options
  • Piping should be replaced when a new tank is installed (standard practice across Nassau County)
  • The Nassau County Department of Health should be contacted for any site-specific requirements
  • Standard homeowner insurance excludes oil spill cleanup under the pollution exclusion clause

Domino's handles all permits and ensures your installation meets every applicable requirement. We have been installing tanks across Nassau County since 1981 and know the local process inside and out.
