Roof repairs, restoration and re-roofing in Parramatta

Parramatta sits at the point where Sydney's oldest housing meets its newest. Inside twenty minutes of Church Street you can stand under a Federation bungalow in Harris Park with its original Marseille terracotta, a post-war brick-and-fibro cottage in Granville, a 1970s split-level in Dundas, and a six-month-old townhouse block in Rydalmere. Every one of those roofs fails differently, and the quote should reflect that rather than a price list.

We cover the City of Parramatta suburbs and the Cumberland side of the line — Granville and Merrylands through to Guildford, Greystanes and Auburn. Call (02) 9090 4741 and tell us what you have noticed.

The four faults we see over and over

Box gutters that were never big enough

This is the signature Parramatta problem. Older homes across North Parramatta, Harris Park and Rosehill — and the thousands of rear additions bolted onto them since — drain through an internal box gutter rather than shedding off an eave. When the sole is too narrow, the outlet is undersized, or there is no working overflow, the water has nowhere to go but up and over the side, which puts it directly into the ceiling cavity.

Current practice under AS/NZS 3500.3 sets a minimum sole width of 200 mm for a house, allows about 30 mm of freeboard, and requires an independent overflow that discharges to open air. A lot of what is up there predates that thinking entirely. If your ceiling only marks in heavy rain and is dry in light drizzle, a box gutter is the first place we look.

Terracotta past its design life

The unglazed terracotta on Parramatta's Federation and inter-war homes was good for a long time, but it is porous by nature and it absorbs more water as the surface weathers. Once the tiles start drinking, they grow lichen, they get heavier, and they become brittle enough to break under a boot. The mortar bedding under the ridge and hip caps usually fails first, and water tracks straight under the capping into the roof space.

Mortar cracked by ground that will not sit still

Parramatta sits on the Cumberland Plain, where the soils weathered from Wianamatta Group shale are moderately to highly reactive clays. They swell in a wet winter and shrink back in a dry summer, and houses on them are routinely classified M or H1 under AS 2870. Small seasonal movement is enough to crack rigid mortar pointing year after year. Flexible pointing exists precisely because of ground like this.

Hail and concentrated runoff

Western Sydney takes the worst of the summer storm season, and Parramatta is regularly inside the warning area when the Bureau calls large hail across the Cumberland Plain. Hail cracks tile and dents sheet metal; the wind that comes with it lifts ridge caps and peels flashings. Then the runoff arrives all at once on a flat catchment with a river running through the middle of it, and anything undersized in the drainage shows up immediately.

What we take on

• Roof repairs — leaks traced to the actual source, slipped and cracked tiles, flashings, valleys and failed capping.
• Roof restoration — high-pressure clean, rebed and repoint the caps, replace broken tiles, seal and recoat.
• Roof replacement — full re-roofs in tile or steel when patching has stopped being economical.
• Metal and Colorbond roofing — tile-to-metal conversions, new sheet roofs, re-sheets over corrected battens.
• Gutter repair and replacement — box gutters, eaves gutters, downpipes, fascia and leaf guard.
• Storm and emergency repairs — make-safe first, documented, then repaired properly.
• Roof inspections and reports — written reports for owners, buyers and insurance claims.

Where we work

From the CBD and Harris Park out through Westmead, Northmead and Oatlands; south across the river through Rosehill, Camellia, Granville and Auburn; west along the railway through Wentworthville, Pendle Hill, Toongabbie and Girraween; and east along the river to Rydalmere, Ermington and Silverwater. The full list is on the service areas page.

How we quote

The inspection is free and there is no obligation attached to it. Someone gets up on the roof, or over it, looks in the roof space where that is possible, and photographs what is actually wrong rather than describing it vaguely. You get a written quote with the work itemised, so you can see what is a genuine defect, what is wear that can wait a season, and what is optional.

We do not quote a roof over the phone and we do not publish figures we cannot stand behind. Roof size, pitch, material, access and how far the damage has already spread are what move the number, and none of those can be guessed from a street view.

Who does the work

Work is carried out by established, licensed and insured roofing contractors working to NSW Fair Trading requirements, and every completed job carries a written workmanship warranty. In NSW, residential building work valued above $5,000 in labour and materials has to be done under licence, and work above $20,000 requires home building compensation cover — both of which are worth asking any roofer about before you sign anything.

Start with a look at the roof

Describe what you have seen — the stain, the dripping eave, the tile on the lawn, the gutter that overflows at the same corner every time — and we will tell you honestly whether it is a half-day repair or something larger.

Call (02) 9090 4741, or send the details through and we will come back to you. No pressure, no obligation.
