What we do

Roofing services in Goulburn

From full roof replacements to fascia and guttering, every job is done by the same family team — and every one comes with a free, no-obligation quote.

Roofing

New Roofing
Full roof installation for new builds and extensions. We work with your builder to deliver a watertight Colorbond roof that handles Goulburn's frost, hail and summer heat from day one.

Re-Roofing
A complete roof replacement over your existing home. If your roof is leaking, rusting or past its best, we strip it back and rebuild it properly — flashings, insulation and all.

Tile to Colorbond Replacements
Ageing tiles crack, slip and let water in. We remove the old tile roof entirely and replace it with lightweight Colorbond steel — stronger in hail, better sealed, and decades of life ahead of it.

Iron to Colorbond Replacements
Old iron roofs rust out at the fastener holes and laps long before they look finished. We upgrade tired iron to modern Colorbond, made for harsh Australian conditions.

Fascia

New Fascia Installation
Straight, cleanly finished fascia to carry your gutters and frame the roofline. Installed to suit new builds, extensions and re-roofs.
Get a quote
Fascia Replacements
Rotting or sagging fascia lets gutters pull away and water get into the eaves. We replace it with durable metal fascia that won't rot, warp or need repainting.

Guttering

New Gutter Installation
New guttering sized and pitched to actually move water — no pooling, no overflow into the eaves during a Goulburn downpour.

Gutter Replacements
Rusted, leaking gutters send water down behind the gutter line and into your walls. We replace them with quality Colorbond guttering, matched to your roof.
