New Roofs Shellharbour
Building or extending? The roof is far cheaper to get right on paper than on site. Send us the plans and we will tell you what is settled, what is still open and what it will cost.

New builds and major additions
Plans reviewed, interfaces sorted early, and installation staged around the rest of the build.
What to send us
You do not need everything finalised to get a useful conversation going. You do need enough for us to quote something real rather than a guess.
Roof plan and elevations
The current set, with the revision date. Working from superseded drawings is how quotes end up wrong by thousands.
Pitch and dimensions
These drive almost everything: which materials are even possible, how the valleys work, and how much water ends up where.
What is still undecided
Tell us. We will state the assumptions in the quote rather than hiding them and surprising you later.
Site and access
What is already on site, how we get materials in, and which trades are working around us and when.
Let the build decide, not the brochure
We work with both, so we have no reason to steer you. The honest answer usually comes down to pitch, structure, budget and how the roof needs to look in its street.
Low pitch pushes you toward metal, because tiles need a minimum pitch to shed water at all. Weight matters to the structure. Tile suits established streetscapes and holds up well over decades. Metal is usually cheaper on a like-for-like home and goes on faster. Our tile roofing and metal roofing pages go through what each asks of the rest of the build.
The gaps between trades
Roof work meets carpentry, masonry, plumbing and electrical, and most new-roof problems are not roofing problems at all. They are things nobody owned because they sat between two trades.
Framing and battens
Set out for the roof material actually being used. Wrong spacing found late is an expensive fix.
Wall junctions
Where the roof meets brick or cladding. Needs deciding before either trade commits, not afterwards.
Penetrations
Flues, vents, skylights and solar mounts. Far better cut in as part of the roof than through a finished one.
Drainage
Gutters, outlets and stormwater sized for the roof feeding them and connected to something that works.
Where the roof sits in the build
Roofing follows the frame and has to be done before the building can be closed up and the interior trades start. That makes it one of the pinch points in a build programme, and being late on the roof holds up everything behind it.
So we would rather be talking to you early than being called at the last minute. We will tell you honestly what lead times look like on the material you have chosen, and where the sequence has to work around other trades. On an addition, the join between new and existing roof is the detail worth resolving first.
A checklist before you compare prices
Make sure every quote covers the same roof and the same drawing revision. Check the material and finish specified, the profile, the underlay or sarking, the insulation, and how the ridges, valleys, flashings and penetrations are handled.
Then check what is excluded: gutters and downpipes, stormwater connection, scaffolding and edge protection, and who covers what if the design changes. A cheaper quote on a new build is nearly always a narrower one, and that difference lands on you later.
Quotes go stale when the design moves
Roof quotes are only as good as the drawings they were built from. If the pitch changes, a penetration is added, or the roof shape shifts during design, the quote needs updating rather than being assumed to still hold.
Send us revisions as they happen. It takes us very little time to check whether anything material has changed, and it avoids the conversation nobody enjoys, which is the one on site about who is paying for the difference.
What a new roof costs
Every roof is quoted in writing after we have looked at it. The ranges below are a guide only and cover most Shellharbour homes; size, pitch, access and the condition we find can move a job outside them either way.
New metal roof on a new build
$15,000 – $30,000
New tile roof on a new build
$20,000 – $40,000
Roof to an extension or addition
$6,000 – $18,000
Plans reviewed and quoted
Free
New-build roofing is quoted from your plans. Send the roof plan and elevations and we can be specific rather than approximate.
New roof questions
What documents do you need to quote a new roof?
Current roof plans and elevations with the revision date, the pitch and dimensions, and any material preferences you have settled on. If selections are still open, say so and we will state our assumptions in the quote rather than hide them.
What does a new roof cost?
A new metal roof on a new build typically runs $15,000 to $30,000 and a new tile roof $20,000 to $40,000. A roof over an extension or addition is usually $6,000 to $18,000. Reviewing plans and quoting is free.
When should I get a roofer involved?
Earlier than most people do. Once the roof appears on the drawings is about right, because pitch, roof shape, valleys, drainage and junctions are far cheaper to resolve on paper than on site.
Tile or metal for a new build?
Pitch usually decides it. Tiles need a minimum pitch, so low-pitch designs push you toward metal. Beyond that it is structure, budget and how you want it to look. We install both and will give you a straight comparison.
Can you work with my builder?
Yes, and it usually goes better when we can talk to them directly about sequencing and the junctions with other trades. Most new-roof problems come from gaps between trades rather than the roofing itself.
What about an addition to an existing home?
The join between new and existing roof is the detail that matters most, because it drives removal, reinstatement, flashing and drainage. We look at that first rather than treating the addition as a standalone roof.
What if the design changes after you quote?
Send us the revision. Checking whether anything material has changed takes us very little time, and it avoids an argument on site about who pays for the difference.
Do you handle gutters and stormwater too?
We quote gutters, downpipes and roof drainage as part of the job or as a clear separate item. Where they connect to stormwater is worth confirming early, because it is a common gap between trades.

Tell us about the project and send the current plans if you have them. If you are still at the sketch stage, tell us that too and we will let you know what we need to be specific.
Extending rather than building new? The join between new and existing roof is the detail worth getting right first, and we will flag it early.
