<\/div>Is your roof ready for winter: Gutters and flashings<\/b><\/h2><\/h2><\/div>By autumn, gutters are full. Leaves, debris and summer build-up settle in over the warmer months, and water that can’t flow freely backs up, spills over and sits against your fascia boards and foundations, often for months without any obvious sign inside the house. Clear them out and check that downpipes are running freely and discharging well away from the house.<\/span><\/p>\nGutter guards<\/b><\/p>\n
If you’re dealing with significant tree coverage, gutter guards<\/b> are worth considering. They reduce how often you need to clear debris and lower the risk of major blockages, but they’re not a set-and-forget solution. Fine debris can still build up on top of and underneath the guards, so gutters should still be inspected at least once a year, even with guards in place.<\/p>\n
Flashings<\/b><\/p>\n
While you’re thinking about the roof, check your flashings<\/b>, the metal strips that seal the joins around chimneys, skylights, and where the roof meets a wall. Flashings are one of the most overlooked parts of any roof and one of the most common sources of water ingress. Over time, sealant dries out and cracks, and metal can lift slightly. Enough to let water in during heavy rain without ever showing up as an obvious leak inside.<\/b><\/p>\n
How often should you get an inspection?<\/strong><\/p>\nFor most homes, a professional inspection once a year is enough to stay on top of it. If you’re in a leafy suburb, near the coast, or somewhere that gets significant storms, every six months is worth it. After any major weather event, it’s always worth getting someone up there. A quick check can catch cracked tiles, loose ridge capping or lifting flashings before they turn into something much more expensive to fix.<\/span><\/p>\nFor a more detailed guide on gutters and spouting, including warning signs, water ingress and when to call a professional, read our guide: Guttering and Spouting: How to Spot the Warning Signs and Prevent Damage.<\/a><\/p>\n<\/div><\/i><\/div>Trades who can get it done:<\/h2><\/div><\/div>\n\n- Roofer\/gutter specialist<\/a> (roof inspection, flashing repair, resealing, gutter cleaning, gutter guards, spouting repairs)<\/li>\n

<\/div>What’s getting in through your walls: Cladding gaps<\/strong><\/h2><\/h2><\/div>On a windy day, run your hand slowly along your window and door frames. If you can feel a chill coming through, that\u2019s often a sign cold air is getting in, and where draughts get in, moisture can follow.<\/p>\n
Gaps and cracks in cladding are one of the most overlooked ways a home loses warmth and lets in damage over winter. Once moisture gets into wall cavities, it creates the conditions for mould, rot and structural damage that can cost far more to fix than the gap itself.<\/p>\n
Walk around the outside of your home and check where different materials meet. Here’s what to look for:<\/p>\n
\n- Gaps or cracking paint where different materials meet \u2014 around window and door frames, along the base of the cladding, at exterior joints and corners<\/span><\/li>\n
- Sealant that has dried out and pulled away from frames or joins<\/span><\/li>\n
- Crumbling or cracked mortar joints on brick homes \u2014 it’s easy to miss because the bricks themselves still look fine<\/span><\/li>\n<\/ul>\n
Small gaps and dried-out sealant can often be repaired with a quality exterior sealant. Anything more serious, lifted or damaged boards, cracking around joinery, or signs of a weathertightness issue, should be assessed by a professional before winter sets in.<\/p>\n<\/div>

<\/div>Where the heat goes, and how to keep more of it<\/b><\/h2><\/h2><\/div>Before you spend anything on heating, it’s worth asking how much warmth your home is actually holding onto. A significant amount of heat is lost through uninsulated ceilings and floors, which means over half of what you’re paying to heat your home can simply disappear if those areas aren’t sorted.<\/p>\n
Underfloor Insulation<\/strong><\/p>\nUnderfloor insulation<\/b> is one of the first things to check, and often one of the least visited parts of most homes. If you have a subfloor space, it’s worth having someone check that batts are still in place, haven’t sagged away from the floor, and aren’t showing signs of moisture damage. Even partial sagging can reduce insulation performance. In ceiling spaces, check for gaps around light fittings, hatches, or penetrations, because these are the spots where heat quietly escapes all winter.<\/p>\n
Draught-stopping and curtains <\/b><\/p>\n
Door draught excluders<\/b>, f<\/span>oam tape around window frames and blocking gaps at skirting boards all make a genuine difference in older homes. Curtains<\/b> are underrated. Floor-length thermal-lined curtains that cover the full window frame can make a big difference for a fraction of the cost, and they\u2019re a much easier place to start than double glazing. <\/span><\/p>\nIf double glazing is on your radar, it’s a worthwhile long-term investment, but get a glazier to assess your home first because the performance difference varies a lot depending on your existing joinery.<\/span><\/p>\nA few things are easy to overlook:<\/b><\/p>\n\n- Lay rugs on bare floors to reduce heat loss through cold floors<\/li>\n
- Use your ceiling fan on a low reverse setting to push the warm air that pools near the ceiling back down into the room<\/li>\n
- Move beds or sofas away from external walls, which are usually the coldest in the house<\/li>\n<\/ul>\n
The sign you have an insulation problem rather than a heating one is simple: some rooms stay stubbornly cold no matter what the thermostat says. <\/b><\/i>
