Mascot Rooftop Transformation — Trex Transcend Composite Decking
A rooftop rental in Mascot, a tired timber structure sitting directly over the tenant’s living room, and a landlord who needed a deck that would stop costing money. I rebuilt the whole space in Trex Transcend composite — the decking I recommend for every rental property I touch — and finished it with an EzGlaze pergola spanning 7.2 metres and a solid privacy screen blocking the neighbour’s pool view. Manually hauling 7.2m EzGlaze sheets up to a rooftop is a physical struggle most builders avoid; it’s the kind of high-stakes logistics I specialize in.
This page tells the story of the build and explains why Trex Transcend is the decking I trust on rental properties across Sydney.
Trex Transcend is my first choice for rentals because its bulletproof capping eliminates the 18-month timber oiling cycle that landlords find impossible to maintain.
| Feature | Specification |
|---|---|
| Material | Trex Transcend (Gravel Path) |
| Capping | High-performance three-sided shell — built for rental wear |
| Sub-structure | H3 treated pine, sealed cuts and joist protection throughout |
| Pergola | EzGlaze polycarbonate roof, 7.2m clear spans |
| Balustrade | White handrails with stainless steel cables |
| Privacy | Integrated solid screen wall blocking neighbour pool sightline |
| Location | Mascot — rooftop installation over occupied living room |
Trex Transcend is my first pick for rentals. The capping is nearly bulletproof, which matters when tenants and turnover are part of the equation.
Mascot was a rooftop build. Every piece of timber, every 7.2-metre roof sheet, every bundle of Trex — all of it hauled up by hand. I hit 37 degrees on that Colorbond roof one day and I left some skin on it when I went down on a knee.
What the landlord ends up with is a maintenance-free asset. No oiling every eighteen months. No splinters. No call-outs from a tenant about a rotted board. That is the whole point.

What the landlord was dealing with
The existing deck was old timber, fixed directly to the rooftop above a tenanted living room. Boards lifting, frame compromised, no fall protection on the perimeter I would sign my name to. For a rental, that combination is an unsafe timber liability sitting one Saturday accident away from a serious claim.
The brief was simple. Strip it back to the colorbond, prove the waterproofing held, rebuild it as a low-maintenance asset, and add a roof and screen so the tenant actually used the space.
Stage 1: Before
Stage 2: Strip it back
Demolition on a rooftop is its own job. Nothing comes down with a machine, every off-cut leaves by hand, and the slab below has to be protected the whole way.
Stage 3: H3 framing on the rooftop
I use H3 treated pine for this build, no water pooling on the roof below and plenty of height and ventilation. Every cut sealed, joist tape over every bearer and joist, packers where the slab needs them.
Stage 4: Trex goes down, screen goes up
Trex Transcend in Gravel Path. Picture-framed perimeter, hidden fixings, every board checked before the next one went in. Balustrade and privacy screen closed out the same stage.
With the deck, balustrade and privacy screen complete, the build moved upward.
Stage 5: EzGlaze pergola with 7.2m spans
The deck went in first. The pergola came afterwards to give them a weatherproof zone — EzGlaze polycarbonate roof, 7.2-metre clear spans, no joins mid-span.
A rooftop the landlord stops worrying about
The old deck was a maintenance problem and a liability question. What replaced it is a Trex Transcend rooftop, a fall-compliant balustrade, a privacy screen the neighbour appreciates as much as the tenant does, and a pergola that makes the space usable year-round.
For a rental owner, the numbers add up. No annual oiling. No board replacement five years in. No tenant complaint about splinters or movement. The decking carries Trex’s warranty and the rest of the build carries mine.
Why I specify Trex Transcend on every rental I touch
Trex Transcend is the product I reach for when a deck has to perform without an owner standing over it. It is built for the use case rental decking actually sees — high traffic, varying tenants, deferred reporting on minor damage, and the same “it should just work” expectation landlords carry across every fixture in the property.
The capping is what makes it work. Transcend uses a high-performance three-sided protective shell. That shell resists fading, staining, scratching, and the kind of damage a rental sees in its first twelve months — dropped barbecues, dragged furniture, planters left sitting for two seasons. Timber takes that damage and shows it. Transcend takes it and does not.
The warranty does the talking. Trex Transcend is covered by a manufacturer-backed limited residential fade and stain warranty — Trex currently ranges this coverage from 25 to 50 years depending on product line and purchase date, so I confirm the exact term in writing at quote stage. For a landlord, that converts to a depreciable asset with a predictable service life — not a recurring maintenance line item.
Total cost is lower over the life of the deck. A hardwood deck on a rental needs oiling roughly every eighteen months, board replacements as the years stack up, and a fall-compliance review every time the surface lifts. Trex Transcend removes all three. The upfront cost is higher than a treated-pine-and-merbau build. The 10-year cost is lower, and the 15-year cost is significantly lower.
It suits rooftops in particular. Composite does not move the way timber does in heat, and on a Mascot rooftop hitting 37 degrees in summer that matters. The board profile sits flatter for longer, fixings stay put, and the picture-frame perimeter detail stays tight.
