Your roof protects everything beneath it, however even small issues can escalate quickly in Canterbury’s wind, rain and occasional hail. If you are seeing any of the red flags below, don’t wait. Early intervention is almost always cheaper than major remedial work later.
Water travels. A minor roof defect can become large ceiling damage, saturated insulation, mould growth, swollen joinery and even compromised framing. The sooner we isolate and fix the cause, the more you will save.
Leaks and water stains
Brown rings on ceilings, damp patches on walls, a musty odour, or water appearing after rain are all classic symptoms of a roofing problem. Even a slow drip can travel along framing and insulation before it shows up indoors. New Zealand’s Building Code sets expectations for keeping water out if moisture is getting in, something’s wrong and it won’t fix itself. Don’t risk it and avoid climbing on the roof. Photograph any interior staining and call Huston Cross for a targeted inspection so we can trace the entry point and stop it at the source.
Sagging or dips in the roofline
A visible dip, ripple or “soft” area often indicates prolonged moisture, compromised framing, or failed underlay. This is a structural and safety concern, especially after heavy rain events and requires prompt professional attention. Don’t wait and book a roof assessment. We’ll check the roof structure, sheet fixings and support members, then propose safe, compliant repairs.
Missing, loose or corroded roofing
High winds can lift fixings, loosen laps and dislodge cappings. Rust on long‑run steel, cracked tiles, or missing ridge flashings create obvious entry points for water. If the damage is localised, we can replace short sheets, refix and reseal flashings, and match profiles. If corrosion is widespread, we will discuss whether re‑roofing offers better long‑term value.
Moss, lichen and mould
Organic growth traps moisture, accelerates corrosion on metal roofs and degrades tile surfaces. Left unchecked, it also blocks gutters and overflows into eaves and even wall cavities. Schedule a professional clean and treatment. We’ll clear gutters and downpipes, then apply appropriate roof‑safe treatments to deter regrowth.
Unexplained energy bill spikes and drafts
Poorly performing roofs often can increase running costs: rooms that are too hot in summer, too cold in winter, or power bills trending up. That can point to either roof insulation issues or inadequate ventilation or potentially air gaps at penetrations and flashings. Get in touch and we will identify problems, recommend improvements, and seal or replace components to restore performance.
