Roofing Glossary

1. Annual Clean: A recommendation for gutter cleaning to be performed once a year, typically sufficient for maintaining functionality in most properties. (Gutter Cleaning – JSJ Roofing)

2. Barge Board: A board fixed to the gable end of a roof to provide support and protect against weather damage.

3. Barge Cover: A protective metal cover made from Colorbond steel, installed over barge boards to shield them from weather damage and eliminate the need for repainting.

4. Bedding: A sand and cement mixture used to secure ridge caps or tiles onto the roof structure, providing a stable base for pointing.

5. Box Gutters: A metal rectangular gutter system installed between two roof sections or along the edge of a flat roof to collect rainwater. These gutters are recessed and often lined to prevent water leakage. (Box Gutter Replacement – JSJ Roofing)

6. Capillary Action: The movement of water through narrow spaces, such as under a flashing, due to surface tension, which can cause leaks if not properly sealed.

7. Concealed Gutter Bracket: A hidden bracket used to secure gutters, providing a cleaner aesthetic and improved water flow.

8. Downpipe Nozzle: The opening of a downpipe that connects to the gutter, designed to channel water efficiently into the downpipe.

9. Downpipe Spreader: A fitting at the end of a downpipe that distributes water across roof tiles instead of directly onto one spot, preventing erosion or overflow.

10. Dutch Gable End: A combination of a gable roof and a hip roof, where the gable is placed on top of the hip roof, adding architectural interest and additional attic space.

11. Extension Flashing: Additional flashing material added to extend coverage and ensure proper sealing under roof tiles or around penetrations.

12. External Corner Bracket: A metal fitting used to join two sections of a gutter system at an external angle (e.g., 90 degrees). It ensures the connection is watertight and securely held in place.

13. Fall Restraint Harness: Safety equipment worn by workers to prevent falls while performing tasks at height, ensuring compliance with WHS (Work Health and Safety) regulations.

14. Finial: A decorative feature or ornament placed at the apex of a roof or gable to enhance its appearance.

15. Galvanized Clip: A metal clip coated with zinc to prevent corrosion, used to secure tiles in valleys or other roof areas.

16. Gutterline: The path along the roof edge where gutters are installed to collect and direct rainwater away from the structure.

17. Internal Corner Bracket: A metal fitting used to join two sections of a gutter system at an internal angle (e.g., 90 degrees). It ensures water flows properly around the corner and prevents leaks.

18. Linear Meter (L/m): A measurement unit used to quantify the length of materials like bird spikes, flashing, or gutters required for installation.

19. Manhole Access: An interior access point, often through a ceiling hatch, used to enter a roof space when external ladder access is unavailable.

20. Nailing Strip: A strip of material added to support and secure installations like barge covers to timber or other surfaces.

21. Pointing: The application of a flexible mortar or compound over the bedding to seal and secure ridge caps, ensuring a watertight finish and accommodating slight roof movements. (Rebed And Point – JSJ Roofing)

22. Rebedding: The process of removing old bedding and applying fresh sand and cement mixture to resecure ridge caps before repointing. (Rebed And Point – JSJ Roofing)

23. Ridge Cap: A curved or angled tile placed along the ridge of a roof to seal the joint between two slopes, protecting against water entry.

24. Repointing: The process of applying fresh mortar to the joints of ridge caps or tiles to restore their seal and ensure water resistance. (Repointing – JSJ Roofing)

25. Sarking: A reflective, waterproof membrane installed under roof tiles or metal roofing to improve insulation and prevent water ingress in case of tile failure.

26. Starter Cap: The initial ridge cap or tile at the end of a roof ridge, often used as an anchor point for subsequent caps and requiring precise bedding and pointing.

27. Stop End: A fitting installed at the end of a gutter to prevent water from flowing out, ensuring it is directed to downpipes.

28. Stink Pipe: A vent pipe that releases sewer gases from a plumbing system. Proper flashing and sealing prevent water ingress. (Stinkpipe Flashings – JSJ Roofing)

29. Valley Iron: A metal channel installed along roof valleys to guide water into the gutters; can be protected with rust-resistant paint. (Valley Clips – JSJ Roofing)

30. Valley Termination: The point where a valley iron meets the gutter system, often requiring flashing to prevent water leakage. (Valley Clips – JSJ Roofing)

31. Weepholes: Small openings in ridge caps or flashing to allow trapped moisture or water to escape, preventing damage.

32. Wakaflex Flashing: A flexible, lead-free roofing flashing material used to seal around roof penetrations or along roof valleys. (Lead Flashings – JSJ Roofing)
