Attic Odors No More: Extending a Sewer Vent Safely Through the Roof

The Problem
A homeowner in Seymour noticed an unpleasant smell in their attic. Upon investigation, they discovered a PVC vent pipe—part of their sewer stack—terminating inside the attic rather than above the roofline. This posed risks for lingering odors, moisture damage, and even pest entry.

Our Approach
A local HEP technician came out to assess the situation. After confirming that the existing pipe was easily accessible in the attic, the technician proposed a combined solution featuring Plumbing Service, Plumbing Install, and Roofing Install. The plan was to extend the vent stack through the roof, install proper flashing, and ensure a weatherproof seal.

Step-by-Step Solution

Inspection & Prep
- The technician verified the pipe material (PVC) and cleared loose insulation to create a safe workspace.
Extending the Vent Stack
- Inside the attic, the PVC pipe was lengthened by approximately ten feet using compatible fittings.
- Each joint was glued and clamped for a leak-free connection.
Creating the Roof Penetration
- A precise opening was cut through the roof decking.
- A pipe boot (flashing) was slid over the pipe, fitting snugly against the roof surface.

Sealing & Weatherproofing
- A generous bead of sealant was applied around the flashing’s edges.
- A vent cap was secured at the top of the pipe to keep out rain, debris, and small animals.
Final Check
- The HEP technician inspected the installation from both inside and outside.
- The homeowner was delighted to find the attic odor gone and the new vent assembly firmly in place.

Why Proper Venting Matters

Healthy Indoor Air: Sewer gases can carry unpleasant odors and health hazards.
Prevent Moisture Damage: Poorly vented pipes can lead to damp insulation and wood rot.
Build to Code: Most local codes require vent pipes to terminate above the roofline for safety.

Tips for Homeowners

Periodically inspect your attic for unusual smells or moisture.
If you spot a vent pipe ending below the roof, call a professional promptly.
After any roofing or plumbing work, check flashing and sealant for cracks.
Keep a photo log of completed work to track maintenance over time.
