Valley Guards — Steel Proofing for Roof Valleys
Where a roof valley forms part of an identified access route, The Possum Man can install steel Valley Guard as part of a possum or rodent proofing solution.

Why Roof Valleys May Need Proofing
Roof valleys are one of the areas we assess when investigating how possums or rodents may be accessing a property. Where a valley forms part of an identified or potential access route, steel Valley Guard may be recommended as part of the proofing solution.
Tiled roof valleys
On suitable tiled roofs, Valley Guard can be fitted where a roof valley is identified as a relevant area requiring proofing.
Metal roof valleys
Valley Guard can also be fitted to suitable metal-roof valley areas where proofing is required.
Why we use steel
The Possum Man uses steel mesh because the system is intended for possum and rodent proofing. Plastic and aluminium guards can be damaged or shredded by animals, which is why we use steel for this application.
Assessment before proofing
We first assess whether the roof valley is relevant to the access problem before recommending Valley Guard.
What Is a Valley Guard?
A Valley Guard is a physical barrier fitted along a roof-valley line where that valley forms part of an identified possum or rodent access route. The Possum Man uses purpose-designed steel mesh, fitted to the roof profile, to help restrict that route.
Rigid steel mesh barrier
Heavy-duty steel mesh fitted along the valley line where that valley forms part of the identified access route.
Steel for animal proofing
The Possum Man uses steel mesh for this application because Valley Guard is being installed primarily for possum and rodent proofing.
Tiled & metal roof valleys
Valley Guard can be fitted to suitable tiled and metal roof valleys where the area requires proofing.
Valley Guards are property-specific. Whether they are appropriate depends on whether a roof valley forms part of the identified access route and on safe access at the property.
Valley Guards Are One Part of Proofing
A Valley Guard addresses access at a particular part of the roof. It does not replace the need to identify and address other entry points or access routes. Possum and rodent proofing considers the property as a whole so that the relevant access and entry issues can be addressed rather than relying on one measure in isolation.
Valley guarding or other proofing?
Where a roof valley forms part of the access route, a Valley Guard may be considered. Where entry occurs elsewhere, other proofing measures may be more appropriate. In some situations more than one access route may need to be addressed.
Tree & vegetation access
Nearby trees and branches can provide climbing access towards roof valleys and gutters, which may call for trimming or a Tree Guard.
Roof & gutter access
Where possums reach valley lines or gutter edges, access-control measures such as Valley Guards or Gutter Guards may be considered.
Other access routes
Nearby structures, overhead cables and building features may also provide access and require separate assessment.
If an animal is already in the roof
Restricting a valley access route does not by itself remove an animal already occupying the roof. Removal and proofing need to be considered together.
How Valley Guard Assessment & Installation Works
Valley Guard installations are property-specific. Here is what to expect from initial contact through to assessment, quotation and installation.
- Step 1
Listen
We start by understanding what you've been experiencing and where the activity is occurring.
- Step 2
Interpret
We consider the pattern of activity and what those observations may indicate before jumping to a conclusion.
- Step 3
Investigate
Where an inspection is required, we examine the relevant roof and valley areas for physical evidence, access opportunities and contributing factors.
- Step 4
Correlate
We compare what you've reported with what we find during the inspection so the evidence is considered together rather than in isolation.
- Step 5
Diagnose
We identify whether the valley forms part of the access route and determine the appropriate proofing solution.
- Step 6
Resolve
If Valley Guard work is suitable, we explain the recommended approach, provide a quote and, where approved, carry out the installation.
Valley Guards Are Quoted After Inspection
Valley Guard installations are quoted after inspection because the appropriate solution depends on the roof type, valley condition and access at the property.
- Step 1
Inspection — $279 + GST
Your inspection allows us to assess the relevant roof valleys and determine whether a Valley Guard is appropriate. If Valley Guard work is recommended, the installation is quoted following the inspection.
- Step 2
Valley Guard — Quoted after inspection
Where suitable, purpose-designed steel Valley Guard work is priced specifically for your property following the on-site assessment.
- Step 3
Pricing & access conditions
Standard inspection/call-out fee applies. Some Greater Sydney locations may have different pricing due to travel or operational requirements. Where this applies, we will let you know before proceeding. See our Pricing & Terms for full details.
A Valley Guard addresses a relevant roof-valley access route as part of an overall possum or rodent proofing plan. It does not replace removal or proofing where these are required, and the property must still be assessed for other access routes. Leaf and debris reduction is a secondary benefit, not the primary purpose.
