Ladder resting against a corrugated metal roof

Overview

Water damage to your home can be costly. Protecting it is a very simple job that can also extend the life of your roof. This guide offers some simple tips to help prepare your roof for the wet season.

Steps

1Clean the gutters

The first step to preparing your roof for the wet season is to clean the gutters. Remove all of the leaf litter from the gutters and check that the downpipes aren't blocked.

2Safety first

Safety is important when you're working on a roof. If you're standing on the roof to clean it, always start on one side and walk backwards away from where you have sprayed. That way you always walk onto a dry part of the roof. If you're working from a ladder, have someone on the ground holding it for you.

3Remove the mould and mildew

Before you start this step, disconnect any water tanks from the gutters so chemicals don't run in to your water storage. Put on safety glasses, dust mask and rubber gloves. Following the instructions on the roof cleaner, spray it onto the roof. Scrub the roof with a brush. Hose the roof cleaner off with water.

4Check your screws

If you have a tin roof, check that all of the screws are securely fixed. Replace any that are damaged. If any of the seals around the screws are worn, use silicone to reseal them.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
