Chimney flashings and skylights are common sources of roof leaks if left unchecked. Our team provides thorough maintenance and sealing to ensure long-term protection—compliant with Victorian Building Authority standards.

Both chimney flashings and skylights are roof penetrations—meaning they’re vulnerable to leaks if not maintained regularly. Melbourne’s climate brings harsh sun, strong winds and driving rain, all of which can wear down sealants, lead flashings and rubber gaskets. Poorly maintained flashings around chimneys or cracked skylight seals can let water creep into your roof cavity, causing serious structural and ceiling damage. We offer proactive servicing and minor repairs, keeping your roof weather-tight and compliant with Plumbing Regulations 2018 under the Victorian Building Authority.
Over time, movement in roofing materials and exposure to UV can break down the flashing around chimneys or skylight surrounds. Signs to look for include ceiling stains near fireplaces or skylights, rust marks, visible gaps in the flashing, cracked sealants, or draughts during windy weather. If left unchecked, minor issues can lead to internal mould, timber rot and costly repairs. Our team conducts detailed inspections to assess condition, identify weaknesses, and apply targeted repairs before damage worsens.
We offer scheduled or one-off chimney and skylight maintenance to suit your property and roofing system. Our licensed plumbers will inspect all flashings and penetrations, check for rust, movement, and cracking, then reseal or reflash where required. We also clean skylight glass, clear surrounding debris, and ensure the area is sealed against water ingress. For chimney flashings, we secure apron, step and counter flashings using compliant techniques to prevent future leaks—all work is completed to VBA standards.
A little maintenance goes a long way. Servicing skylights and chimney flashings regularly helps prevent emergency repairs and costly water damage. These roof elements often go unnoticed until a storm reveals the problem. Our team identifies issues early and carries out high-quality repairs that match your roof type—metal, tile, Colorbond or slate. For properties with older chimneys or retrofitted skylights, maintenance is essential to protect against shifting materials or outdated sealants. We’ll help you stay one step ahead.

Frequently Asked Questions
We recommend a maintenance check every 2–3 years, or sooner if your home is exposed to strong winds or has an older roof. Melbourne’s seasonal changes can cause flashing movement and gasket wear over time. Regular checks help avoid costly water damage.
Most Melbourne homes use metal apron and step flashings around chimneys, often in Colorbond or lead. We match the existing material and use compliant methods that meet VBA regulations for weatherproofing and long-term protection.
