Why Choose Us for Flashing Repair in Como?
A lot of Como homes have had additions over the years, and that's where flashing gets tricky. The old mortar cracks, water tracks in around the new extension, and suddenly there's a ceiling stain. Flashing is the metal that seals where the roof meets a wall or vent, and failures usually run $400 to $950. We replace the corroded metal and re-bed it with flexible mortar that moves with the house instead of cracking like old sand cement. We'll check your valleys at the same time, because Como's leaf runoff does real damage there.
Flashing failures at wall junctions are common in Como, especially on homes that have been added to over the years. The crumpled original brickwork plus new extensions create complex junctions where water finds its way in. River humidity and freeze-thaw cycles age flexible sealants fast. We typically find failed flashing during leak investigations, it's rarely the first thing homeowners think to check, but it's often the culprit.

Local Como Expertise
Como stretches along the southern bank of the Canning River just 6km from Perth CBD, making it one of Perth's most accessible riverside suburbs. Subdivided as the Como Estate in 1905, the area's housing tells the story of decades of riverside growth - Federation and interwar character homes from the 1920s and 1930s, solid brick-and-tile homes from the 1950s-1970s, and pockets of 1990s infill development where original homes were subdivided. Towering river red gums, swamp paperbarks, and mature jacarandas form a dense canopy across the suburb, creating beautiful but challenging conditions for roofs. At Roof Restorers Perth, we've restored hundreds of roofs across Como, Manning, and Salter Point with 15+ years of team experience, with particular expertise in the older terracotta and concrete tile systems that define this riverside suburb.
The result: Restored roofs engineered to handle Como's high humidity, heavy leaf load, and diverse housing ages - protected by Dulux Acratex coatings with 15-year manufacturer warranty.

Benefits of Flashing Repair for Como Properties
Seals the most common leak point
Flashing is the metal that seals the joins where the roof meets a chimney, wall, valley or vent. It's where most tiled roofs leak, and on tile it's where we fix more leaks than anywhere else.
Repaired properly, not bodged
If the flashing's just lifted or the seal's perished, we strip it back and reseal it. If it's rusted or was never installed right, we patch and re-secure the join so it sheds water again. Either way it's done to last, not bodged with a tube of silicone.
Stops the leak at the source
Sealing the flashing fixes where the water's actually getting in, so the ceiling stain stops spreading. Flashing sits outside our leak warranty, so we'll tell you honestly what we can and can't stand behind before we start.
Fully insured
We carry $10M public liability and work safely across tile, metal and flat roofs throughout the Perth metro.
Our Flashing Repair Process in Como
- 1
Find the failed flashing
We inspect the chimneys, walls, valleys, vents and penetrations and identify which flashing has lifted, perished or rusted.
Why it matters: Flashing failures are easy to miss from the ground.
- 2
Strip the old seal
We remove the failed flashing or perished sealant back to a clean, sound surface.
Why it matters: New sealant won't bond over old, cracked material.
- 3
Reseal and re-secure
We reseal sound flashing and patch or re-secure it where it's lifted or rusted, lapped and fixed so water sheds away from the join.
Why it matters: Correctly lapped flashing sends water out, not in.
- 4
Check the surrounding roof
While we're at the join we check the nearby tiles, pointing and valleys, since flashing leaks often sit alongside other wear.
Why it matters: Where one thing's failed, the next is usually close.
Flashing Repair in Como - FAQs

How do I know if my roof flashing needs repair in Como? ▾
Look for water stains on interior walls near the roof, especially after winter rain or heavy storms. Flashing failure at wall junctions is common in Como's homes with additions. If you see cracked sealant or rust on metal flashings, get it checked, river humidity accelerates corrosion.
Are flashing repairs expensive in Como? ▾
Flashing repair at a single junction typically runs $400 to $950. Complex renovated homes with multiple additions may need several junctions repaired. The key is catching it early, leaks traced to failed flashing are cheaper to fix than the ceiling damage they cause if ignored.
How much does roof flashing repair cost in Perth? ▾
A reseal of sound flashing is a small job. Patching and re-securing rusted or badly installed flashing costs more, especially around a chimney. We find what's failed first, then give you a price before any work starts. Call 08 6388 4492.
Can you fix chimney flashing? ▾
Yes. Chimney flashing is one of the most common leak points on a roof. We reseal or patch the flashing around the chimney so water sheds away from it instead of tracking down inside.
My roof leaks where it meets a wall. Is that flashing? ▾
Almost certainly. The join where a roof meets a wall is sealed with flashing, and it's a classic leak spot when that flashing lifts or perishes. We reseal or patch it so the join sheds water properly again.
Do you replace valley flashing? ▾
Yes. Rusted-through valleys are a major leak source on older Perth roofs. We repair the valley iron where it's still serviceable, and there's a dedicated valley replacement service if the whole valley's gone.
Do you repair flashing on a metal roof? ▾
For metal and Colorbond roofs we specialise in cleaning and repainting rather than leak work - our leak repair and leak warranty cover tiled roofs. If you've got a leak on a metal roof we'll tell you straight rather than take the job on.
Is flashing work covered by your warranty? ▾
No. Our 12-month workmanship guarantee covers repointing, rebedding, tile replacement and leak repairs on tiled roofs. Flashing, flues, whirlybirds and other roof penetrations sit outside it, and so do metal roofs. We'll set out exactly what's covered before you commit.
Will silicone fix my flashing leak? ▾
A smear of silicone might hold for a few months, but it's not a repair. Failed flashing needs the old seal stripped and the join resealed or patched properly. That's what actually lasts.
