Price to erect double garage roof?

Postby Meccarroll » Sun Sep 17, 2017 6:56 am

Hi all just out of interest I was wondering if anyone on here knew how much the going rate is to erect a double garage roof (pitched roof over a double garage)?

Also an estimate of how long it should take to erect including all facias and bargeboards.

Just so you know I've already put this roof up but may have others to do. The price was fixed.

The size of the roof 5.7m wide by 7m long (length is gable end side).
Rafters spaced every 600mm (0.6m)
Pitch approximately 30 deg.
Two gable ends with wood ladders made on site for overhanging barge boards (ladders not pre made).
Facia and Barge boards in plastic with soffit all around the building including the gables.
Bracing as usual, node points, diagonals in roof and on ceiling joist.

I'll let you know what the price was set at by the builder after I've had a bit of input.

Cheers Mark

The roof is truss type not a cut roof.

Last one I did a few years ago which was gable ended both ends with Sussex Barn hips at each end took 2 of us around 6 days.This was for a traditional cut n pitch roof with collars,purlins,strutts etc. The barge boards,fascias, soffits etc and general fannying around probably took another day.

What are "node" points?.

A couple of chippies who do roofs all day long could have done it quicker but I had to scratch my head a bit... :roll:

Did a single garage week before last, it was built against the house so 5 sets of spars onto a ridgeboard coming away from the house, then two hip rafters and jack spar, all cripplings , fascias and soffits (pvc).
6x2 ceiling joists, 1x9 ridge board, 5x2 spars, 2x9 hips and dragon ties, 1x6 binders.
2 men started at 08.30, on way home finished at 15.45.
The job was for a builder I sub to regularly and we did it on daywork so not sure of his price. I would have been looking for about £600 had I been putting in a price.

The roof you did Leveler, would be quite different to construct to th truss roof I have just done quite a bit more work and skill involved in your roof so can't draw a fair comparison but thank you for the reply. The node points as I understand are the intersections between the roof members in the truss. Points where the members are gang nailed together.

About £1200 if your lucky, 2 men 3 days but most likley you had to do it in 2 days so £800 but I dont do house bashing so I am just guessing really.

The price for the roof was £507

This is for a house builder and scaffold is erected and a digger is available to lift materials onto the scaffold but thats it.

Time wise, I had a labourer for four hours on the first morning to help lift the trusses on the wall plate and I took just over three days to complete the roof in total.

I think the price was tight at £507. The scaffold I worked from was not at the right height (too low meaning I had to use a hop up and move it around to work from) nor was the roof decked out inside the garage (would have given a working platform internally) , had both of these been done I could have saved nearly a day in time.

I think to work on builders pricing strategy, everything need to be in place (materials, scaffolding, weather) as prices are cut to the bone (very tight).

Thank you for the replies.

Regards Mark
