Roof Maintenance Checklist for Waikato Homes

Safety first — stay on the ground

Before the checklist, the golden rule: most roof maintenance can be done, or at least monitored, from ground level, and that's where we'd rather you stayed. Roofs are slippery, roof edges are unforgiving, and ladders account for a lot of nasty home accidents.

You can check a surprising amount with your feet on the grass and a decent pair of eyes (binoculars help). For anything that means actually getting onto the roof — or onto a ladder in an awkward spot — that's the point to call someone who does it for a living and has the gear to do it safely.

Seasonal checks through the year

You don't need to be up there every week. A rhythm tied to the seasons keeps on top of things without it becoming a chore:

• Autumn — the big one. Clear gutters and valleys of fallen leaves before winter so the heavy rain has somewhere to go. Check nothing's blocking the downpipes.
• Before winter — do a proper once-over for anything that could let water in during the wet months: loose fixings, tired flashings, cracked tiles.
• After big storms — a quick ground-level look for lifted sheets, dislodged flashings, fallen branches and blocked gutters.
• Spring — check for moss and lichen build-up after the damp winter, and clear any debris that's accumulated.
• Summer — a good time for any work that needs dry weather and safe access, and to deal with overhanging branches.

Gutters and downpipes

If you do only one thing for your roof, keep the gutters clear. Blocked gutters and valleys are behind a huge share of roof and water problems — when water can't drain, it backs up, overflows, and gets forced in under the roofing and against the fascia.

• Clear leaves, moss and debris out of the gutters, especially in autumn and under any trees.
• Check downpipes are flowing freely and not blocked at the top or the outlet.
• Look for sagging, rusted or leaking gutter sections and joints.
• During rain, glance out to see whether water is overflowing anywhere — that tells you where a blockage or fall problem is.
• Check the valleys (the internal gutters where two roof planes meet) are clear, as these dam up easily with debris.

Moss, lichen and debris

The Waikato's damp, green climate is perfect for moss and lichen, and over time they do real harm — holding moisture against the roof, and on tile roofs even lifting and dislodging tiles. Debris does similar: anything sitting on the roof traps moisture against the surface.

• Keep an eye on shaded, south-facing and tree-covered sections where moss and lichen take hold first.
• Clear built-up leaves and debris off the roof, out of valleys and away from behind flashings.
• Deal with moss and lichen before it spreads — but don't reach for the water-blaster on a fragile or coated roof, which can do more damage than the moss.
• Cut back overhanging branches where you safely can, to reduce both debris and shade.

Flashings and fixings

Most leaks start at the detailing, not in the middle of a sheet — so flashings and fixings are where a careful eye pays off. These are things to check properly during the before-winter once-over.

• Look at the flashings around chimneys, where the roof meets walls, along the ridge and at the barge ends for lifting, splitting, corrosion or perished sealant.
• Check the seals around penetrations — vent pipes, flues, aerials and the like — haven't perished or pulled away.
• On steel and iron roofs, look for fixings that have backed out, worked loose or corroded.
• On tile roofs, scan for cracked, chipped or slipped tiles and any that have gone missing.
• Watch for any rust starting, especially in valleys, under eaves and anywhere that stays damp.

The from-the-ground inspection

Here's how to do a genuinely useful inspection without leaving the ground. Walk the full way around the house and look up at the roof from every side — the different angles reveal different problems. A pair of binoculars turns this from a vague glance into a real check.

Look along the ridge and roof planes for any sag or wave in the line. Scan the sheets or tiles for anything lifted, cracked, slipped or rusting. Check the flashings and the gutters as far as you can see them. And pop your head into the roof space (the attic or ceiling cavity) with a torch on a dry day and again after rain — daylight coming through, damp patches, water stains or a musty smell all tell you something's up before it reaches your ceilings.

When to get a pro up there

Ground-level monitoring is great for catching that something needs attention — but acting on it often means getting onto the roof, and that's the line. Call in a professional when you've spotted something that needs a closer look or a fix, when you can't tell from the ground what's going on, when the roof is steep or hard to access, or simply for a periodic proper inspection to catch what you can't see.

A professional check every so often is cheap insurance: a roofer finds the small stuff — a lifting flashing, a loose fixing, early rust — while it's still a quick fix rather than a leak and a wet ceiling.
