Housing Age Profile

The year 1986 marks a critical threshold in residential plumbing safety: that's when the federal government banned lead solder from new construction, closing a major pathway for lead entering household drinking water via pipe joints. Roanoke's median build year of 1947 signals that most of the city's housing was built under the newer standard. The distribution above tells the full story - the post-1986 majority lowers aggregate risk, but the pre-1986 share still deserves scrutiny from anyone living in or purchasing an older home.

Pre-1986 (Lead Paint Risk)

Most homes in Roanoke were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Roanoke: Lead Risk & Vulnerable Populations

mg/L Avg Lead (Limit: 0.015)

Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.

Lead risk in Roanoke appears low overall, but individual homes may differ. Testing is the only way to confirm your water's lead content.

Roanoke: Flood History & Water Damage Risk

A moderate NFIP record for Roanoke - 1532 insurance claims paired with 0% of ZIP codes in FEMA flood zones - points to a flood history where water-quality pathways have likely been periodically relevant.

Est. Claims/Year

Roanoke has a moderate flood history with 1,532 FEMA claims. Flood events can contaminate drinking water and overwhelm treatment systems.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure.

Residents in flood-prone areas should consider flood insurance even outside FEMA zones - over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
