What We Fix

Leak Repairs – We find where the water’s getting in and fix it properly. Sometimes it’s obvious, sometimes it takes a bit of hunting.
Damaged Sheet Replacement – Corroded or damaged sheets get replaced with new ones that best match your existing roof.
Storm Damage Repairs – High winds and falling branches wreck roofs. We repair storm damage and get your roof sealed up again.
Rust Repairs – Small rust spots can be treated and sealed. Bigger rust problems might need sections replaced.
Flashing Repairs – Flashings around chimneys, skylights and walls are common leak spots. We repair or replace flashings that have failed.
Ridge Capping Repairs – Loose or damaged ridge capping lets water in. We re-secure or replace it properly.
Fastener Replacement – Old screws and nails work loose or rust out. We replace failed fasteners and seal the holes.
Failing Internal Spouting/Guttering – We can convert your internal spouting to timber fascia with external spouting to prevent water overflowing into your soffits and wall cavities.

Common Roof Problems

Here’s what usually goes wrong:

Leaks around penetrations – Anywhere something goes through your roof is a potential leak point. Chimneys, vents, skylights and pipes need proper flashings.
Valley leaks – Valleys channel lots of water. If they’re installed incorrectly or they’ve corroded, they leak.
Rust and corrosion – Old roofs rust. Coastal areas are worse. Catch it early and you may be able to repair it.
Wind damage – Strong winds lift sheets, break fasteners and tear flashings. Northland weather is hard on roofs.
Debris damage – Falling branches, airborne objects in storms, or just wear from overhanging trees all cause damage.
Failed sealants – Sealants around penetrations dry out and crack over time. Water finds a way in.

Warning Signs

Don’t ignore these:

Water stains on your ceilings or walls. If you can see water damage inside, your roof could be leaking.
Drips or wet patches when it rains. It’s likely you’ve got a roof leak.
Daylight visible through the roof from your ceiling space. You shouldn’t be able to see sky.
Rust spots or holes in the roofing. Small rust can be fixed. Don’t wait until it’s holes.
Loose or missing sheets after wind. Needs sorting before the next storm.
Damaged or missing flashings. Check around chimneys and where walls meet the roof.
Water pooling on the roof. Water should run off, not sit there.

Repair or Replace?

Sometimes it’s hard to know which way to go. Here’s a rough guide:

Repair makes sense when:

The leak or damage is isolated to one area
The rest of the roof is in reasonable condition
The roof is relatively young
You’re planning to replace it in a few years anyway

Replacement makes more sense when:

You’re getting multiple leaks in different spots
The roof is old and deteriorating everywhere
Rust is widespread
Repair costs are adding up to a big chunk of replacement cost

We’ll advise what makes sense for your situation.

Keep Your Roof in Shape

Regular maintenance catches problems early:

Keep gutters clear. Blocked gutters cause water to back up under the roof edge.
Trim overhanging branches. They damage roofs in wind and drop debris constantly.
Check your roof after big storms. Look for loose sheets, damaged flashings or debris.
Don’t walk on your roof unless you know what you’re doing. You can cause more damage.
Regular roof cleaning to prevent moss and lichen growth and painting will protect your roof material and improve your it’s lifespan
