Product Information
Full details
The McAlpine RS4 Aluminium Roof Flashing is designed for homeowners and builders needing a reliable solution to prevent water leaks around roof penetrations. Its key benefit is providing durable, flexible, and corrosion-resistant sealing for pipes and chimneys on various roof types, offering cost savings over traditional methods. A potential caveat is its suitability limitation for roofs beyond a 45-degree pitch.

Extended Product Information
FAQs
What is the maximum roof pitch this flashing can be used on?
The McAlpine RS4 Aluminium Roof Flashing is suitable for roof pitches up to 45 degrees.
Can this flashing be used with any type of roof covering?
Yes, it is designed to be compatible with most common roof coverings, including tiles, slates, and shingles.
Is this flashing suitable for flat roofs?
Yes, it can be used on both flat and pitched roofs up to a 45-degree angle.
Do I need special tools for installation?
Standard roofing tools should suffice. The flashing is designed for easy dressing using hand manipulation. Refer to installation instructions for specific guidance.
What is the advantage over traditional lead flashing?
It offers cost savings in both materials and labor, is lighter to handle, and is corrosion-resistant for long-lasting protection without the environmental concerns associated with lead.
Is the rubber collar UV resistant?
The synthetic rubber collar provides a good seal. While designed for outdoor use, prolonged extreme UV exposure over many years may eventually affect its material properties. Periodic inspection is recommended.
What is included with the product?
The product includes the McAlpine RS4 Aluminium Roof Flashing with its integrated synthetic rubber collar. Fasteners for securing the base are typically not included and should be selected based on the roof structure and local building codes.
Troubleshooting
Minor water seepage observed after installation.
Re-inspect the seal around the pipe/chimney and the integration with the roof covering. Ensure the rubber collar is fully seated and that flashing edges are properly dressed to direct water away. Check for any fasteners that may have compromised the seal.
Flashing does not conform well to the roof profile.
Carefully manipulate the corrugations to better match the roof's undulations. For very complex profiles, additional sealing compound may be considered, though typically the flashing's design is sufficient.
Corrosion or discoloration noticed on the aluminium.
While the flashing is corrosion-resistant, extreme environmental conditions can sometimes cause surface discoloration. This is usually cosmetic and does not affect performance. Ensure no harsh chemicals have come into contact with the surface.
Pros and Cons

Setup, Compatibility & Care
Setup:
- Ensure the roof penetration area is clean and clear of debris.
- Place the flashing over the penetration, ensuring the synthetic rubber collar fits snugly around the pipe or chimney.
- For pitched roofs, position the base of the flashing to follow the roof's slope and conform to the underside of the tiles/slates above.
- Use appropriate fasteners (not included) to secure the base of the flashing to the roof structure or battens if required by local building codes or specific roof type.
- Carefully dress the flashing edges to integrate with the roof covering, ensuring water will run off the flashing and away from the penetration.
Compatibility:
- Suitable for roof pitches from 0 to 45 degrees.
- Compatible with a wide range of roof coverings including tiles, slates, and shingles.
- Ideal for use with flue pipes from condensing boilers.
- Can be used on both flat and pitched roofs.
Care:
- The flashing is designed for low maintenance. Periodically inspect for any signs of damage or debris accumulation.
- Clean with a damp cloth if necessary. Avoid abrasive cleaners that could damage the aluminium or rubber collar.
