Overhead Electrical Service Mast Repair & Replacement
Repair and replacement of overhead service masts, weatherheads and roof penetrations so the utility's drop stays anchored and dry.
The pipe holding your service drop
On homes with overhead service, the mast is the rigid pipe running through the eave or roof that carries your service conductors down to the meter and takes the mechanical pull of the utility's overhead drop. Front Range weather is hard on them: wind loading, ice on the drop line, hail on the weatherhead and decades of sun on the roof boot.
A mast that has shifted is not cosmetic. Once it leans, the drop pulls at a bad angle, the roof penetration opens up, and water starts tracking down the pipe into the meter housing and sometimes into the panel itself. Most of the corroded meter sockets we replace started as a mast problem.
- A mast that visibly leans or has pulled away from the wall
- A cracked, missing or sun-rotted weatherhead
- Water staining below the roof penetration or inside the meter can
- A service drop hanging lower than it should over a driveway or yard
- Storm or tree damage that moved the pipe
What the repair involves
Depending on the damage we either re-set and re-brace the existing mast or replace the pipe, weatherhead, roof boot and straps outright. Where clearance rules have changed since the house was built, or the drop hangs too low over a driveway, we correct the height at the same time so the utility will re-attach without a fight.
The utility disconnects the drop, we do the work, the inspector signs off, and the utility re-attaches. We schedule all of it, including the roof detail that keeps the next twenty winters out of your service.
- Rigid conduit, weatherhead, straps and roof flashing replaced as a set
- Attachment point and guying corrected for real-world wind load
- Clearances over driveways, walkways and roofs brought current
- Conductors inspected and replaced where insulation has failed
Mast, meter and panel usually travel together
Because the mast, meter housing and panel are one continuous system, we look at all three at the estimate. Often the honest answer is that the mast alone is the job. Sometimes the mast is the visible symptom of a service that has been quietly taking on water for years, and we will show you photographs rather than ask you to take our word for it.

Pricing
What moves the price on this job
We quote after seeing the equipment, because these details change the number more than anything else.
- Mast height, pipe size and roof pitch
- Whether the service conductors are reusable
- Roof material and the flashing detail required
- Whether the meter housing is being replaced at the same time
- Permit and utility fees in your jurisdiction

Prequalifying takes about a minute and uses a soft credit check, so seeing your options does not affect your credit score.
FAQ
Common questions
Is a leaning mast an emergency?
If conductors are damaged, arcing, or the drop is low enough to touch, treat it as urgent and call the utility first for safety. If it is leaning but intact, it is a scheduled repair, and it should not wait a season.
Does the utility repair the mast?
No. The utility owns the drop and the meter; the mast, weatherhead and housing belong to the home. They will disconnect and re-attach, and we do the work in between.
Can the mast be repaired instead of replaced?
Sometimes. If the pipe is straight and the corrosion is limited to the weatherhead and flashing, re-bracing and re-heading it is a real option. We quote the honest lesser fix when it exists.
Will you fix the roof leak too?
We seal and flash the electrical penetration properly as part of the job. Broader roof damage around it is a roofer's work, and we will point it out with photos.
Do I need a permit for mast work?
Yes, service work is permitted and inspected in every jurisdiction we work in. The fees are in your written quote.
