If you would rather add to the house than leave the street, the roof is the part that decides whether it looks like it belongs. Get it wrong and the addition announces itself from the kerb forever.
Pitch, overhang, ridge height, gutter line and profile. Those five things are why some extensions vanish into the house and others look bolted on. It is not the paint colour and it is not the brickwork.
So the roof over an extension gets set against the roof you already own, not off a standard detail out of a folder. And the joint where the new roof meets the old one is the part that leaks when it is done cheaply, which makes that joint the whole job.
The frame goes up and gets set to the existing pitch. The new roof is tied into the old one and flashed at every junction. Gutters and downpipes are run so the extra roof area has somewhere to drain, which is the bit that gets forgotten until the first proper downpour. Then the finish: sheeting or tiles chosen against what is already on the house.
Anything structural, and anything that changes the footprint of the house, is a council conversation. Have it early. We will tell you what we can see from the roofing side, and we will not quote around an approval that has not been sorted.
None of these cost much to get right at the start. Every one of them costs a fortune to fix afterwards.
A degree or two out reads as wrong from the street even when nobody can put their finger on why. It gets measured off the existing roof rather than assumed off a plan.
New fascia sitting above or below the old line is one of the most visible tells there is, and it is the hardest to disguise once the sheeting is on.
Where the new roof meets the old is the joint that leaks. Silicone is not a flashing and it never has been, no matter how neatly it goes on.
Extra roof area means extra water. If the downpipes and the stormwater were never sized for it, the first heavy autumn downpour will let you know about it.
We would rather raise all four at the quote than come back in two winters to undo them.
We are not going to invent one. Span, pitch, material, how it ties into the existing roof and what the frame has to carry move the number far enough that a published range would mislead you. Yours gets quoted in writing and itemised, after somebody has been out and measured it.
What we can publish are the ranges for the roof you already have. A full restoration on a three to four bedroom home is $4,000 to $9,000. A high pressure roof clean is $800 to $2,000. A full replacement in Perth commonly starts around $20,000. All of it is broken down in the cost guide.
Full roof restorations carry a 15-year written guarantee, signed on the quote. Exactly what it covers is set out in plain words on our guarantee page.
Plenty of extensions sit next to an existing roof that could do with attention at the same time. One trip, one quote.
"Mati and Ryan did a fantastic job and I can't believe how wonderful my roof looks! Tiles replaced, ridge capping repaired, painted and sealed, plus extra jobs done at the last minute!"
"Awesome job. Great at communications and really looks after his clients. Rare to find people who will do their job and provide proper support these days. Killi is definitely one of them."
"Mati and his team did a great job on my roof. He was so busy but promised he would have it done by Christmas and he did. So happy with his work. Would highly recommend this company."
Yes. Roof extension work sits alongside restorations, repairs, re-roofing, gutters, cleaning and painting. Tell us what you are adding on the job sheet and we will come and look at how it has to tie into the roof you already have.
That is the job. Pitch, profile, overhang and gutter line all get set against your existing roof so the addition reads as part of the house rather than an afterthought. Where an exact material match is no longer made, we show you the closest option before anything is ordered.
Usually, and it depends on your local council and on what you are building. Sort that out early rather than after the quote. We will tell you what we can see from the roofing side, but the approval itself sits between you and your council.
We work right across the Perth metro, north and south of the river. These suburbs have a page of their own: Baldivis, Canning Vale, Joondalup, Midland, South Perth, Wanneroo, Applecross, Ascot. If yours is not listed we almost certainly still get there, so ask and we will tell you straight away.
Bring the plans if you have them and the rough idea if you do not. We come out, look at how it has to meet the existing roof, and quote it in writing.
