A roof tie-down is the continuous chain of connections holding the roof down to the walls and footings against wind uplift. We assess that load path against the site’s wind classification, then reinforce it with framing anchors and proper anchorage where it falls short. Any tile-to-Colorbond re-roof in Como changes the sum, because a lighter Colorbond roof raises the net uplift the tie-down must resist.
Roof tie-downs in Como: the short version
Tie-downs are structural, not cosmetic. The roof has to be held down to the walls, and the walls to the footings, in one continuous path that can resist the wind trying to lift it off. Where that path is incomplete, corroded or under-built for the exposure, it needs reinforcing — and where a roof is being re-covered, it needs reassessing. As registered builders we assess, rectify and certify that work across Como and nearby suburbs like Salter Point. Full detail on our roof tie-downs service page.
Why Como roofs behave the way they do
Como has a piece of building history that genuinely changes how its houses should be inspected. In 1948-49, more than a thousand blocks were created here and the suburb became a testing ground for experimental prefabricated. “expansible” houses, homes designed to be thrown up quickly against a desperate post-war housing shortage. The shortage was severe enough that the City allowed families to live in caravans on their own blocks while their houses went up. Identify the construction before assuming anything about it Experimental housing was built for speed, not longevity, using non-standard details. Where examples survive, or were later built onto, expect unusual wall and floor systems, junctions that were never intended to last seventy-five years and additions grafted onto a frame never designed to carry them. A conventional inspection checklist applied to a non-conventional house will miss the things that matter. Establishing what the house is actually made of comes first. Not always. The scale of that release also means a very large body of homes of near-identical vintage. Late-1940s and 1950s problems recur across whole streets, original services well past life, asbestos-era materials and roof and wet-area fabric at or beyond a second cycle. Two pieces of geography shape the rest. Canning Highway cuts the suburb in half, so properties near it carry real traffic noise and the two halves differ in character. And where Como runs down toward the Swan River, the low parcels carry a high water table and estuarine damp working at masonry.What that means for tie-downs in Como
The more sheltered river suburbs generally sit at a lower wind classification, so the load is smaller — but that’s no guarantee the tie-down is adequate. A lot of the older housing around Como predates modern connection standards, so the load path can be nominal by today’s measure even where it was sound for its day.
We assess the existing connections and complete the load path where it falls short — framing anchors, triple-grips and proper anchorage down to the footings — so the roof is tied continuously to the ground rather than relying on the weight of the tiles alone.
And whenever an older Como home is re-roofed from tile to lighter Colorbond, we reassess the tie-down, because removing that dead weight raises the net uplift the connections have to resist.
It’s the same load-path work we bring to homes through Manning and Karawara, and it’s worth understanding how the wind actually tests a Perth roof before it’s put to the test.
Como roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Recent tile-to-Colorbond re-roof | Dead weight removed, net uplift raised | Tie-down reassessment |
| Rusted straps or anchors in the roof space | Corroded load path | Renew connectors, restore anchorage |
| Truss cut for a skylight, duct or solar | Load path broken by a later alteration | Reinstate to designed capacity |
| Older home, exposed or elevated block | Connections predate current standards | Assess classification, reinforce path |
Guide only. Every roof differs, which is why we assess before quoting.

Roof Replacement in Como
Learn moreWhen a Como roof is genuinely finished, we re-roof it to suit an established riverside home — framing and sarking sorted while it's open, flashings detailed properly, and a considered choice between a traditional tile look and lighter Colorbond. The aim is a roof that fits comfortably on a Swan-side street and outlasts the one it replaces, whether it's a character house or something more recent.

Roof Carpentry in Como
Learn moreUnder Como's older foreshore homes there's framing that's absorbed years of river damp, and where a leak's been added on top the timber has often quietly gone. We repair it properly — cutting back to sound wood, matching the old framing, and stopping the water at its source above — so a lovely riverside home isn't left with rot working away beneath a roof that looks fine from the street.

Roof Inspection in Como
Learn moreA Como home — house or unit — can hide an aged roof behind a well-kept front, so a look before you buy is worth it. We check the tiles, pointing, valleys and flashings on a pitched roof, or the box gutters and membrane on a flatter one, and get into the roof space where we can, then hand you a clear photographed report so the roof isn't an unknown when you make your offer.

Storm Damage Repair in Como
Learn moreComo's big riverside trees and the flat foreshore setting make a storm a real risk — a branch down, water finding its way in fast. We move quickly to secure and seal the roof without adding harm to an older structure, then assess the full extent, which after an impact means checking the framing beneath the tiles. If a claim's involved we photograph and document everything from the first visit.

Roof Repairs in Como
Learn moreComo runs along the Swan and mixes older character homes with a good deal of unit and townhouse stock, so the roof work is varied — perished pointing and cracked tiles on the houses, plus flashing and box-gutter issues on the flatter roofs of the units. We match the tile where it's a pitched roof, sort the detailing where it's not, and always trace the leak to where the water genuinely enters rather than where it shows.

Structural Defect Repairs in Como
Learn moreEstablished Como roofs carry the usual structural history — spread rafters, a settled ridge, framing softened where a long leak and river damp got into the timber. When an inspection names a genuine fault, we diagnose what's really moving, work respectfully on an older home, engage an engineer where warranted, and certify the rectification, so a sale clears rather than stalling on the building report.

Signs a Como roof’s tie-down is worth checking
- The roof has been re-covered from tile to Colorbond without the tie-down being reassessed
- The home is older, or on an exposed or elevated block, and has never been checked against current standards
- A truss or rafter has been cut for a skylight, duct, air-conditioner or solar install
If any of these apply on your Como home — or on a place you’re buying in nearby Waterford — it’s worth a look. See also how to spot roof damage you can’t see from the ground.
Local conditions in Como
Como was a testing ground for EXPERIMENTAL PREFABRICATED and 'EXPANSIBLE' houses in 1948-49, homes designed for speed rather than longevity and built to non-standard details. Where any survive or were built onto, expect construction that does not follow conventional practice: unusual wall. That matters. Floor systems, joints and junctions that were never meant to last 75 years and additions grafted onto a frame never designed to carry them. Identify the construction type before assuming anything about it.
Over 1,000 blocks released in two years means a large body of homes of near-identical vintage. The same late-1940s and 1950s issues recur across whole streets: original services long past life, asbestos-era materials and roof and wet-area fabric at or beyond the end of a second cycle.
Canning Highway cuts the suburb in two, properties on or near it carry substantial traffic noise and the two halves differ in character and value.
We cover the whole of the City of South Perth. Short drives keep roof replacement affordable on smaller jobs and most of ours are smaller jobs.
Standards and certification
Tie-down work is governed by the wind and framing standards, not opinion. Wind classification is set under AS 4055, wind actions under AS/NZS 1170.2, and timber framing and its connections under AS 1684. We work to those standards by name and reference them in what we hand back.
The other thing that matters in Western Australia is who signs it off. Structural rectification and certification must be done by a registered builder — Powerdrive holds Builders Registration BC105819, so we can assess, rectify and certify the tie-down. It’s worth checking any roofer’s registration before you hire them, and where the frame itself has weakened we put that right at the same time.
A little about Como
Originally three land grants purchased by Christchurch farmer Edmund Hugh Comer in February 1891; recognised as a new suburb around 1898; established 1905; Canning Highway Divides THE Suburb; ~6.7km², ~14,786 pop The 1950s and 60s saw further development of surrounding areas by the State Housing Commission and under War Service Homes Housing shortages were such that the City Allowed People TO Live IN Caravans ON Their Properties While Their Houses Were Being Built None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Como.
What the work involves
- Assess the wind classification. We establish the site’s wind classification under AS 4055, and on exposed sites work to the wind actions in AS/NZS 1170.2, so the tie-down is designed to the load the roof actually sees — which matters most heading into storm season.
- Trace the whole load path. Roof to walls to footings, in one continuous chain. We find where it’s incomplete, corroded or under-built — the concealed connectors that a quick look never checks.
- Reinforce to standard. Framing anchors, triple-grips and chemical masonry anchors installed to AS 1684, completing the anchorage down to the footings.
- Reassess on every re-roof. A tile-to-Colorbond conversion removes dead weight and raises the net uplift, so we reassess and upgrade the tie-down as core to any re-roof, never an optional extra.
- Certify the work. As registered builders (BC105819) we can certify the structural work — which a general contractor can’t — and it pairs naturally with a documented roof inspection.
Common questions about roof tie-downs in Como
What is a roof tie-down and why does it matter?
A tie-down is the continuous chain of connections that holds the roof down to the walls and the walls to the footings, resisting the wind trying to lift the roof off. In Perth’s wind region it’s a genuine structural requirement, and where the path is incomplete or corroded the roof relies on far less than it should.
Does converting my tile roof to Colorbond affect the tie-down?
Yes — this is the big one. Lightweight Colorbond removes the dead weight that helped hold a tile roof down, which raises the net wind uplift the tie-down has to resist. Any Como re-roof should trigger a tie-down reassessment, and one that skips it can leave the roof less secure than before.
Do I need a registered builder for tie-down work?
In Western Australia structural rectification and certification must be carried out by a registered builder. Powerdrive holds Builders Registration BC105819, so we can assess, rectify and certify the work — it’s worth checking registration before hiring any roofer.
How do you work out how strong the tie-down needs to be?
We establish the site’s wind classification under AS 4055, and on exposed sites work to the wind actions in AS/NZS 1170.2, so the tie-down is designed to the load the roof actually sees — which is especially worth doing before storm season.
Do you work throughout Como and nearby?
Yes — across Como and neighbouring suburbs including Salter Point and Manning. Ring 0421 768 842 and tell us your street. If a tie-down assessment isn’t what your roof needs, we’ll say so rather than quoting anyway.
