1. Double-Wall Leak Protection
A steel tank is a single wall of metal between your heating oil and your basement floor. When it corrodes through, oil hits the ground. A Roth tank has two walls. The galvanized steel outer shell holds 110% of the inner tank's capacity. Even in a worst-case scenario, no oil leaves the tank. Your floor, your soil, and Long Island's groundwater stay protected.
2. 30-Year Manufacturer Warranty
Roth backs every tank with a 30-year limited warranty covering manufacturing defects. Steel tanks typically carry a 1-year to 10-year warranty and most manufacturers will not cover internal corrosion, which is the primary way steel tanks fail. The Roth warranty reflects the confidence the manufacturer has in the product's durability.
3. $2 Million Environmental Insurance
Every Roth tank includes 10 years of environmental coverage: up to $2 million for cleanup costs and $2 million for third-party property damage per occurrence. An oil spill from a steel tank can cost $10,000 to $100,000 or more to remediate, and standard homeowner policies exclude oil contamination under the pollution exclusion clause. Roth's included insurance fills that gap completely.
4. Zero Corrosion Risk
Steel tanks corrode from the inside out. Condensation forms on the interior walls, mixes with sulfur in the oil, and creates acidic water that eats through the steel. Microbial growth (sludge) accelerates the process. Pitting can begin within 5 years. The Roth HDPE inner tank is completely immune to rust, corrosion, pitting, and microbial attack. It will never degrade from contact with heating oil or moisture.
5. Built-In Leak Detection
An optical sensor sits in the space between the inner and outer walls. If oil ever enters that interstitial space, the sensor triggers an alarm. You know about a problem immediately, not weeks or months later when oil has already soaked into your concrete floor or seeped into the soil beneath your home. Steel tanks have no leak detection of any kind.
6. Lighter and Easier to Install
A Roth 275-gallon tank weighs approximately 140 pounds empty, compared to roughly 250 pounds for a steel 275. The lighter weight makes it easier to carry down basement stairs, maneuver through tight doorways, and position in spaces with low ceilings. Roth also offers low-profile models for basements where a standard-height tank will not fit.
The Real Cost of a Steel Tank Leak
What happens when a single-wall steel tank fails on Long Island.
When a steel oil tank develops a pinhole leak, the oil drips onto your basement floor and seeps into the concrete. If the leak goes undetected for days or weeks, the oil can migrate through cracks in the slab and contaminate the soil underneath your home. On Long Island, where the water table is shallow and the sole-source aquifer supplies drinking water for millions of people, soil contamination from heating oil is treated as a serious environmental event.
Here is what a steel tank leak can cost:
- Soil testing and environmental assessment: $2,000 to $5,000
- Excavation and removal of contaminated soil: $10,000 to $50,000
- Groundwater monitoring wells: $3,000 to $8,000 per well
- Ongoing groundwater monitoring (required for years): $2,000 to $5,000 per year
- Full remediation of a serious spill: $50,000 to $100,000+
- Loss of property value during and after remediation
- Potential liability to neighbors if contamination spreads
Your homeowner's insurance will not cover any of it. The standard pollution exclusion clause in residential policies specifically excludes heating oil contamination. You would pay every dollar out of pocket.
A Roth tank eliminates this risk entirely. The double-wall design means oil never reaches your floor. And even if something completely unexpected were to happen, the included $2 million environmental insurance policy has you covered.
Protecting Long Island's Drinking Water
Long Island's drinking water comes from a sole-source aquifer, a single underground water supply with no backup. Nassau and Suffolk Counties rely entirely on this aquifer for residential, commercial, and agricultural water. The EPA designated it a sole-source aquifer in 1978, meaning there is no alternative supply if it becomes contaminated.
Every leaking oil tank on Long Island is a direct threat to this shared water source. Oil that enters the soil eventually reaches the water table. Once groundwater is contaminated, cleanup is extremely difficult and expensive, and the effects can last for decades.
Roth double-wall tanks are the single most effective way for homeowners to prevent oil contamination. The secondary containment shell catches any leak before oil can escape, and the built-in alarm detects a problem before it becomes an emergency. That is why environmental officials, insurance companies, and oil delivery companies across Long Island recommend or require double-wall tanks.
Who Makes Roth Tanks
Roth Industries is a German-engineered manufacturer that has been producing double-wall oil tanks since the 1960s. The company operates manufacturing facilities in Europe and North America and has installed millions of tanks worldwide. In the United States, Roth tanks are manufactured to meet UL 2258 (Standard for Safety of Aboveground Double-Wall Tanks) and comply with NFPA 31 (Standard for the Installation of Oil-Burning Equipment).
Roth is not a rebranded product or an import sold under a different name. The company designs, manufactures, and warranties every tank under its own name. The 30-year warranty and $2 million environmental insurance policy are backed directly by Roth and its insurance partners.
Roth requires that all installations be performed by certified installers to maintain warranty coverage. Domino's Oil Tank Service has been a certified Roth installer since the company began offering double-wall tanks on Long Island, and we have installed hundreds of Roth tanks across Nassau and Suffolk Counties.

How a Roth Tank Is Built
Two walls, two materials, one purpose: protect your home from oil leaks.
Every Roth tank starts with a seamless, blow-molded inner tank made from high-density polyethylene (HDPE). This is the same material used in food-grade containers and underground water mains. HDPE does not rust, pit, corrode, or react with heating oil. There are no seams, welds, or joints that can weaken over time.
The inner tank is enclosed inside a galvanized steel outer shell. This outer wall is not just a protective cage. It is a fully sealed secondary containment vessel designed to hold 110% of the inner tank's total volume. If the inner tank were ever compromised, the outer shell would catch every drop of oil before it reached your floor.
Between the two walls sits an optical leak sensor. If oil ever enters the space between the inner and outer tanks, the sensor triggers an alarm immediately. You would know about a problem long before any oil could escape the tank.
This three-layer protection system (corrosion-proof inner tank, secondary containment outer shell, and leak detection sensor) is what makes Roth the safest residential oil tank on the market.
Roth Tank FAQ
What makes Roth tanks different from regular steel oil tanks?
Roth tanks use a double-wall design with a seamless blow-molded HDPE inner tank surrounded by a galvanized steel outer shell. The inner tank cannot rust or corrode, the outer shell holds 110% of the inner tank's volume, and a built-in optical leak sensor sits between the two walls. Steel tanks are single-wall, corrode from the inside out, and have no secondary containment or leak detection.
How long does a Roth oil tank last?
Roth tanks carry a 30-year limited manufacturer warranty, and many last well beyond that. The HDPE inner tank does not corrode, pit, or degrade from contact with heating oil. By comparison, steel tanks typically start corroding internally within 5 to 10 years and often fail within 15 to 20 years.
What does the $2 million environmental insurance cover?
Roth includes 10 years of environmental coverage: up to $2 million for cleanup costs and $2 million for third-party property damage per occurrence. This covers soil remediation, groundwater contamination, and damage to neighboring properties. Standard homeowner insurance policies exclude oil spills under the pollution exclusion clause, leaving you unprotected if a steel tank leaks.
Can a Roth tank be installed in a tight basement?
Yes. Roth tanks are lighter than steel tanks of the same capacity, making them easier to carry down stairs and maneuver through narrow doorways. Roth also makes low-profile models designed for basements with low ceilings. The 275-gallon low-height model is the most popular choice for Long Island homes with limited basement clearance.
Is a Roth tank worth the extra cost over a steel tank?
Yes. A steel tank costs less upfront, but the total cost of ownership is much higher. Steel tanks need replacement every 15 to 20 years, have no environmental insurance, and carry the risk of an oil spill that can cost $10,000 to $100,000 or more to clean up. A Roth tank lasts 30+ years, includes $2 million in cleanup insurance, and eliminates any risk of oil reaching your floor, soil, or groundwater.
Are Roth tanks approved for use on Long Island?
Yes. Roth tanks are UL 2258 listed, NFPA 31 compliant, and approved for indoor and outdoor residential use across New York State. They are the preferred tank among Long Island oil companies, insurance providers, and environmental regulators.
