ENSURING LONGEVITY AND PERFORMANCE
Maintaining your roof is essential for ensuring its longevity and optimal performance. Regardless of the type of roofing material, regular checks and appropriate care can prevent potential issues and extend the life of your roof. In this comprehensive guide, we will delve into expert advice from various sources to help you understand the key aspects of roof maintenance.
Common Roofing Materials in New Zealand
Consumer NZ points out that galvanized or coated steel is the most common roofing material in New Zealand, followed by coated metal and concrete tiles. The maintenance tasks discussed in this guide are applicable to all types of roofs, but some may be specific to certain materials. It’s crucial to consult your roof manufacturer for specific maintenance requirements tailored to your roofing type.
Annual Roof Maintenance Checks
Consumer NZ emphasizes the importance of annual maintenance checks, covering roof cladding, chimneys, and flashings. These checks involve climbing onto the roof using a ladder, ensuring safety measures are in place, and avoiding wet surfaces to prevent slipping accidents. The source advises against working on roofs with a pitch over 15 degrees without proper safety measures.
You should have your roof inspected once a year to check:
- Roof cladding, fixings, and flashings
- Chimneys and Flues
- Gutters and Downpipes
- Roof mounted equipment such as solar panels, or star link dish.
Tips for Safe Roof Access:
- Make sure someone knows you will be working on the roof
- Ensure the roof is dry before climbing.
- Follow the WorkSafe guide for working on roofs
- Use your ladder safely.
- Walk along the nail lines.
- Use a roof ladder for roofs over 15 degrees.
- Securely fix safety ropes for inaccessible roof sections.
Some New Zealand homes might still have asbestos in the roofing material. Specialist services should be used in the maintenance, restoration and replacement of any building material containing asbestos.
Addressing Specific Roof Maintenance Needs
Cladding
Consider washing the roof annually, dependant on the cladding material and environmental conditions. A regular routine of washing increases the longevity of your roof by removing contaminants such as salts and organic matter. More information can be found on the Colorsteel website. Concentrate on washing areas that don’t receive rain, such as under eaves.
Guttering
Ensure the guttering is clear of organic buildup, and check for areas of rust or disrepair. This is essential where there is rain water collection for household use. Consider dry cleaning options, such as using a brush to minimise water use.
The BRANZ Healthy Houses Report (2016) identified “Ten of the fourteen sample houses required gutter maintenance, ranging from simple clearing and cleaning through to a full gutter replacement. Effective guttering removes stormwater from the dwelling and channels it away to maintain dry conditions”
Chimney Flue, Pipe, Cowl and Fastenings
- Ensure your flue is cleaning annual prior to use in winter. Ensure the flue is connected securely and there is no corrosion in the flue pipe or cowl.
- Replace corroded or loose nails with new roofing nails or screws.
- Replace severely corroded flashings, and secure lifted or dislodged flashings
Trees:
Trees can cause a number of problems to your roof, including branches connecting with the roofing during high winds, and dropping leaves into your gutters. Trim overhanging branches to prevent damage to roofing materials, and consider a gutter guard.
Expert Advice from the New Zealand Roofing Association
The New Zealand Roofing Association emphasizes the importance of regular maintenance for roofs, wall cladding, and rainwater systems. Professionals use safety controls like edge protection, scaffolding, or cherry pickers for working at heights. The association also encourages homeowners to use their free consumer advice guide for roof restoration and maintenance.
