Despite the roof being the vital part of the home, it often escapes the scrutiny of the home buyer as it is out of sight and out of mind – requiring a professional assessment. Research from our pre-purchase home assessments has shown that at least 50% of all homes assessed have some type of roof problem.
Often when homes are sold, a fresh coat of paint is used to cover long term tell-tale water stains on the interior ceilings and walls or in the case of a metal roof, a fresh coat of paint on the exterior could suggest a quick artificial makeover of a rusty roof.
The cost of repairing water damage by a leaking roof on plaster, especially lath and plaster in older homes can run into thousands of dollars and is usually discovered after people move in and experience the first heavy downpour. This damage can be caused by a simple lack of maintenance in clearing out guttering or down pipes which cause the water to back up and enter the home.
Apart from the appearance of the roof, it is also vital that inside the roof cavity is assessed for constructional soundness.
Following major storms and heavy rain, leaky roof problems can lead to dangerous situations where water can penetrate walls, roofing and insulation leading to the growth of mould and deterioration of the home. People who put off having leaks fixed could be putting themselves and their families at risk, especially if the water was likely to enter the electrical system or appliances.
- Check guttering and down pipes are clear of fallen leaves, sticks and other debris.
- If there have been storms or high winds look for broken or cracked roof tiles, loose ridge
and valley tiles allowing bird and possum entry as well as water leaks.
- Check that corrugated iron sheets are in good condition and well attached.
- Ensure valley and eaves guttering are free from holes and rust. Even small holes can
create large leaks often making extensive replacement necessary.
- Make sure flues and chimneys are safe and flashings around them are secure against water penetration
- Check inside the roof space for water stains or pinholes of light indicating holes in the
roof or flashings.
