Re-Roofing and Roof Replacement, Macarthur

There is a point where you stop repairing a roof and start replacing it. Across the Campbelltown estates, a lot of houses reached that point in the same handful of years — because they were built in the same handful of years.

Full re-roofing in tile or Colorbond, across Campbelltown, Camden and the Macarthur growth corridor. Free inspection, written quote, nothing to sign on the day. (02) 4601 5100.

When another repair stops making sense

Replacement is a big call and it should be argued for, not assumed. These are the things that tip a roof over the line:

• Tiles crack underfoot. Concrete tile gets brittle with age. If walking the roof on the proper line breaks tiles, every future repair creates new damage.
• Leaks keep appearing somewhere new. One recurring leak is a fault. Three unrelated leaks in two years is a roof.
• Soft battens. Timber that has been damp for years will not hold a fixing, and no amount of pointing fixes that.
• Nothing left to coat. Tiles worn back past their surface layer will keep absorbing water no matter what goes on top.
• Widespread hail fracture. Hairline cracks across a whole roof plane, rather than a few tiles, are not individually repairable.

If none of that describes your roof, you probably want roof restoration instead, and we will say so.

Tile for tile, or tile to Colorbond

Both are legitimate. The choice depends on the house and the street.

Staying with tile keeps the look of the original estate, which matters on a street where every other roof is the same profile, and matters more in the Camden and Queen Street heritage areas where roof form is assessed. Modern concrete tiles are a better product than their 1970s ancestors.

Going to metal is the more common swap out here. Colorbond steel sheds water fast at low pitch, carries nothing that can be cracked by hail, has no pointing to perish in the heat, and weighs far less than concrete. It also lets you run anticon blanket or thicker insulation over the frame during the install, which is worth real money in a Macarthur February.

What changes when you switch material

Swapping tile for sheet is not just a different covering, and anyone who tells you otherwise has not done many.

• Battens get reset. Tile battens and sheet battens sit at different spacings. The new layout follows the sheet manufacturer's span tables, not the old tile spacing.
• Pitch has to suit the profile. Each profile has a minimum pitch. A low-pitch skillion over an alfresco needs a different sheet to a 22-degree main roof.
• Valleys, flashings and barges all get replaced, not reused. Old galvanised valleys are usually the oldest failing part of the roof anyway.
• Insulation and sarking go in while the frame is open. This is the one chance to do it properly, and it is cheap at that moment.
• Gutter capacity gets reviewed. A faster-shedding roof puts water into the gutters more sharply than tile did.

How a re-roof actually runs

1. Inspection and measure. Roof area, pitch, hips, valleys, penetrations, access, frame condition, and anything that looks like asbestos.
2. Written quote with material, colour, inclusions and exclusions itemised. Residential work over $5,000 has a written contract under NSW law; over $20,000 the home building compensation certificate is attached to it.
3. Strip, section by section. The roof is never left open overnight and work stops ahead of a storm front.
4. Frame check and repair. Soft battens and damaged timber are replaced while visible.
5. Sarking or anticon, then new covering, laid with new fixings, valleys, flashings and ridge detail.
6. Clean-up, including a magnetic sweep of the ground, and a written workmanship warranty.

Approvals and the heritage question

Most straightforward re-roofing on a house is exempt development in New South Wales — minor building alterations like repairing or replacing roof cladding sit outside the development application process, provided nothing structural changes and the work is like-for-like in character.

The exceptions matter locally:

• Heritage items and conservation areas. Campbelltown City Council assesses work in the Queen Street Heritage Conservation Area against heritage controls, and Camden Council does the same through the Camden town centre conservation area. A material or profile change on one of those buildings is a planning conversation first, a roofing job second.
• Changing the roof form, adding a dormer or raising a parapet, is a different matter again and is not exempt.

If your house is in Camden or Elderslie or the older blocks near Queen Street, raise it at the inspection and we will tell you straight whether it needs council involvement.

What drives the price

Roof area and pitch first, then complexity: a simple gable roof over a 1980s four-bedroom in Eschol Park is a very different job to a cut-and-fill two-storey at Mount Annan with six valleys and a parapet. Access on the block, scaffolding or edge protection on steeper sites rising toward the Scenic Hills, the material and colour you choose, frame repairs found once the roof is open, and asbestos removal if bonded sheeting is present.

You will get one written number with the lines showing, after someone has been on the roof. Call (02) 4601 5100 or use the quote form, and if a restoration would serve you better we will tell you that instead.
