Bedding is the mortar bed the ridge and hip caps sit on; pointing is the flexible compound finished over the top. Over time the bedding cracks and the pointing perishes, the caps loosen and water gets under them. We lift the failed caps, lay a fresh mortar bed and re-point in a flexible compound that moves with the roof. It’s the most common roof repair in Bassendean, and the core of any restoration. Free inspection, written quote, 10-year workmanship warranty.
Bedding and pointing in Bassendean: the short version
Ridge and hip caps are held by a mortar bed and sealed with pointing. Both have a life, and when they go the caps rock loose and let water in at the very top of the roof. Re-bedding and re-pointing sets them solid again and seals the ridge line — a targeted fix, not a whole-roof job. We do the same work through nearby Eden Hill; more on our bedding and pointing service page.
Why Bassendean roofs behave the way they do
Bassendean is the type-site for the Bassendean Dune System, the oldest and most leached dune system on the Swan Coastal Plain and that geology carries a specific, uncommon inspection flag. The Bassendean sands include documented low-sulfur, potentially-acidic (acid sulfate) soils. Where those soils are disturbed or dewatered, by excavation, drainage or a dropping water table, they can turn acidic, which corrodes concrete footings and steel and affects drainage. That is the pattern. Near the river and in the low, wet parts of the suburb, that is a genuine consideration that simply does not arise on the limestone-and-sand suburbs of the coast. Bassendean is also a genuinely old riverside suburb, once known as West Guildford, settled from 1829, so it has heritage cottages and character precincts like the Old Perth Road area. On the oldest stock that means timber-frame and asbestos-era checks and in the character areas, some constraint on what can be altered. There is also a long history of railway rolling-stock industry here (from 1951), so parts of the suburb carry an industrial context. Being a river suburb rather than a coastal one, salt-driven delignification is a low priority in Bassendean. The distinctive local concern is underfoot: the old, leached Bassendean sands and, in the low and disturbed areas, the acid sulfate soil risk to footings and drainage.What that means for bedding and pointing in Bassendean
Around the river suburbs the ridge line ages on a steady schedule, and perished pointing is simply the most common thing we find on an older Bassendean tiled roof. It rarely fails dramatically — it just quietly lets water in until a ceiling stain appears.
We re-bed and re-point the whole ridge and hips so the fix is uniform rather than patching one cap and leaving the next to go a month later.
It’s the same ridge work we carry out through Lockridge and Kiara, and knowing the early warning signs saves you a stained ceiling.
Bassendean roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Mortar crumbs in the gutter | Bedding and pointing at end of life | Re-bed and flexible re-point |
| A ridge cap visibly rocking or slipped | Bedding cracked, cap loose | Lift, re-bed, re-point |
| Cracked lines along the ridge pointing | Rigid pointing perished | Flexible re-point |
| Ceiling stain near a ridge or hip | Water tracking under a loose cap | Re-bed the caps, trace the leak |

Roof Restoration in Bassendean
Learn moreA lot of Bassendean's older homes are ready for a restoration — faded colour, crumbling pointing, a roof that's dragging the whole house down. Where the tiles are sound it's a good-value job: treat the moss the river damp encourages, clean, re-bed and re-point the ridges, and re-coat to seal and refresh the surface. It brings the colour and the character back on an established home for a fraction of what replacing it would cost.

Roof Repairs in Bassendean
Learn moreBassendean's an established riverside suburb with a lot of older character housing, and its roofs show the years — perished pointing, cracked tiles, and tired flashings around the Swan-side blocks. Most of our repairs here are that steady work: match the tile so the fix blends in, re-point the ridge in a flexible compound that won't crack out again, and trace the leak back to where the water really gets in rather than sealing the stain inside.

Roof Cleaning in Bassendean
Learn moreDown by the Swan the air stays damp, and Bassendean's roofs grow moss and lichen readily on their shaded sides, on top of the usual weathering. We treat the growth so it dies at the root instead of greening back after the next rain, then clean the surface to an even colour at a pressure the tile can take. On many of these older homes a proper treat-and-clean is genuinely all the roof needs.

Roof Replacement in Bassendean
Learn moreOnce a Bassendean roof is genuinely spent, replacement is the honest answer, and it's the moment to fix everything at once. With the tiles off we can see and sort the old framing and sarking, put proper flashings and valleys in, and choose a material — tile or Colorbond — that suits an established riverside home. Done once, done right, it takes the house decades forward instead of buying another year.

Roof Carpentry in Bassendean
Learn moreUnder Bassendean's older roofs there's often decades-old framing that's absorbed river damp and the odd slow leak, and by the time it shows the timber has usually gone soft. We repair it properly — cut back to sound wood, splice or replace to match the old framing, and fix whatever let the water in above it — so the structure's honest again rather than quietly rotting under a roof that looks fine from below.

Roof Inspection in Bassendean
Learn moreWith so much established housing in Bassendean, a pre-purchase roof inspection is worth the money. We check the tiles, pointing, valleys and flashings and get into the roof space to look at the sarking and older framing, then hand you a plain written report with photos. On a character riverside home the roof is often the biggest unknown, and it's far better to know what you're taking on before you sign.

Signs a Bassendean roof needs re-pointing
- Mortar crumbs washing into the gutters
- Ridge or hip caps that look slipped, uneven or are visibly rocking
- Cracked, powdery pointing along the ridge line
If you can see any of that on your Bassendean roof — or one you’re buying in nearby Bayswater — it’s worth doing before winter. See also the signs a roof needs attention.
Local conditions in Bassendean
The type-site for the Bassendean Dunes, documented LOW-SULFUR POTENTIALLY-ACIDIC (acid sulfate) soils. Where disturbed/dewatered, acid sulfate soils corrode concrete footings and steel and affect drainage. A genuine, specific ground flag near the river/low areas.
Oldest, most leached dune sand, low fertility, low reactivity, but acid-sulfate risk in low/wet areas is the key.
Old West Guildford, heritage cottages and character precincts (Old Perth Road); timber-frame + asbestos-era on the oldest.
Long rail rolling-stock industry, some industrial land/context in parts.
River, not coast, salt/delignification low priority.
We cover the whole of the Town of Bassendean. Short drives keep roof replacement affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
The compound matters. Rigid sand-cement pointing looks fine on day one and cracks out as the roof moves — which is why we finish in a flexible pointing compound designed to flex with the tiles and hold for years. The mortar bed underneath is laid to a proper mix, not thrown in.
Re-bedding and re-pointing is also the foundation of a full roof restoration: there’s no point coating a roof over a ridge line that’s about to let go, so we always sort the capping first. It’s worth checking any roofer uses flexible pointing before you hire them.
A little about Bassendean
Railway rolling-stock construction/maintenance since Commonwealth Engineering opened a plant 1951 (later Goninan); closed/changed over time Once 'West Guildford'; Henty brothers granted 2,000 acres 1829 (Stoke Farm, mud-brick homestead); along the Swan River Gives its name to the Bassendean Dune System, the oldest, most leached dune system on the Swan Coastal Plain; documented LOW-Sulfur, Potentially-Acidic (acid sulfate) soils/sediments None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Bassendean.
What the work involves
- Lift and assess. We lift the loose or cracked caps, check the tile and batten underneath, and clear the old bed back to a sound surface.
- Fresh mortar bed. The caps are re-bedded on new mortar, set true to the ridge line so they sit solid rather than rocking.
- Flexible re-pointing. We finish with a flexible pointing compound — not rigid mortar — so it moves with the roof and doesn’t crack out again the first hot summer.
- Check the ridge over. While we’re up there we flag anything else the ridge needs, and pair it with a restoration where the whole surface is due, not just the caps.
Common questions about bedding & pointing in Bassendean
What’s the difference between bedding and pointing?
Bedding is the mortar bed the ridge caps sit on; pointing is the flexible compound finished over the top to seal them. Both wear out — when they do, the caps loosen and water gets under. We renew both.
Why does the pointing keep cracking?
Almost always because rigid sand-cement pointing was used. It can’t move with the roof, so it cracks the first hot summer. We use a flexible pointing compound that flexes instead — it’s the difference between a fix that lasts and one that fails again.
Is re-pointing worth it or should I just re-roof?
If the tiles and structure are sound, re-bedding and re-pointing is a fraction of a re-roof and buys years — read how long a Perth roof should last. If the whole roof is at end of life we’ll say so rather than pointing a roof that needs replacing.
Can you match the mortar colour?
Yes — flexible pointing comes in a range of colours, so we finish the ridge to suit the tile and the house rather than leaving a mismatched grey line down the roof.
Do you re-bed and re-point throughout Bassendean and nearby?
Yes — across Bassendean and neighbouring suburbs including Eden Hill and Lockridge. Ring 0421 768 842 and tell us your street. If the ridge doesn’t need it we’ll say so rather than quoting anyway.
