Why can't your electric utility fix a storm-damaged weatherhead on your roof?
If high winds rip the electrical pipe and cap off your siding, the power company cannot touch it. Here is how the legal demarcation line works.
When I reviewed residential storm repair guidelines after severe summer squalls ripped through Midwest communities, one homeowner frustration appeared constantly: utility crews restoring the street's main power lines while leaving a house disconnected because of a bent metal pipe on the roof. Homeowners understandably wonder why a utility lineworker cannot simply straighten the pipe and hook the wires back up. What we find when examining electrical codes is a strict legal and safety boundary known as the point of attachment.
The electrical connection to your house is divided into two distinct ownership zones. The utility company owns and maintains the overhead wires leading from the pole transformer to your property, known as the service drop, as well as the glass digital meter itself. However, every piece of hardware permanently attached to your home's exterior walls or roof framing is private property, owned solely by the homeowner. When we trace the path of electricity from the sky into a home, that physical boundary determines who can legally turn a wrench.
The Anatomy of Customer-Owned Service Equipment
Understanding what belongs to the house clarifies why utility lineworkers are legally prohibited from repairing it. The customer-owned assembly consists of four critical parts:
- The Weatherhead (Service Head): The curved, hood-shaped cap at the top of the vertical conduit that points downward, allowing insulated wires to enter while keeping rain and snow out.
- The Service Mast (Riser Conduit): The rigid galvanized steel pipe running vertically down the roof or siding that protects the incoming wires from physical damage and bears structural tension.
- The Meter Base (Socket Box): The rectangular metal enclosure mounted on the exterior wall that securely houses the utility's glass electric meter.
- The Service Entrance Cable: The heavy conductors inside the conduit that carry 240-volt electrical power from the weatherhead through the meter base into your main breaker panel.
Why Utility Lineworkers Cannot Make Private Repairs
Utility workers are trained and certified to maintain grid-scale distribution assets, but municipal building codes and the National Electrical Code (NFPA 70) require private home electrical repairs to be executed by licensed electricians. If a tree branch pulls a service mast loose, the underlying wooden rafters, exterior fascia, or siding anchors may be structurally compromised. Utility lineworkers cannot take on the liability of repairing private building carpentry or internal conduit.
Connecting live high-voltage power to a cracked weatherhead or damaged meter socket creates severe fire and arc-flash hazards. If water enters the mast pipe, moisture can seep directly into the main breaker panel in the basement, risking catastrophic short circuits and destroying home electronics.
The Step-by-Step Restoration Route
If a storm damages your service mast or meter enclosure, following a clear sequence gets power restored smoothly:
- Call a Licensed Electrician: Hire an insured electrician to inspect the damage, replace broken conduit, and anchor a new weatherhead firmly to the building framing.
- Obtain Local Inspection if Required: In many municipalities, the city building inspector must sign off on the new mast installation to certify compliance with local building safety codes.
- Notify Your Utility Company: Once repairs are certified, call your electric utility provider to report that your customer-owned equipment is fully repaired and ready for safe reconnection.
The Joyful Ingenuity of the Weatherhead Drip Loop
There is a wonderful, enduring elegance in the mechanical design of the weatherhead. For over a century, electrical engineers have relied on the simple geometry of a downward curve combined with an intentional sag in the wire called a drip loop. Gravity forces rainwater to slide down the insulation to the bottom of the loop and harmlessly drip onto the ground, never climbing upward into the pipe. As I watched technical diagrams of this setup, the sheer simplicity of using gravity rather than complex gaskets felt deeply satisfying. When an electrician bolts a fresh, gleaming mast into place and the utility crew finally clips the service drop to your anchor hook, that quiet click of reconnection brings unmatched household relief.
