Hi all,
Inspired by Tricky Dicky's question about extensions, does anyone know of an online resource for calculating the cost of a new roof based on square metre-age, choice of tiles or slates, sarking yes/no and so on?
I could certainly use one! thanks, cd.
I have some 2008 estimate figures here for a 3 bed semi, that suggest entry level is about £5K with cheap tiles, rising to £11K for more expensive materials.
Yes why is scaffold so expensive though? Brian
We had a hipped roof re-slated 4 years back on a 3 bed semi, the total came to about £3000 of which £600 was the cost of scaffolding. The only mat erial costs were breathable under felt, roof laths and a handful of replace ment slates. Took 2 guys the best part of a week to strip and replace.

Don't overlook the cost of scaffolding and/or removal of rubbish/old roof.
Terrace house with a right angle ridge section over the bay windows and an extra 4 tile width sub-roof at the back of the property in SE Essex = just under £5k.
It would have been more if I had chosen better quality tiles - but the ones I've got will outlive me by a few decades or more.
Scaffolding 4 men for a _long_ day to erect, 3 men for a day to dismantle
2 men (1 skilled , the other more of a labourer) to strip old slates and battens and to replace with membrane, battens, tiles and lead flashing in around 4 days. Quite a lot of lead flashing - at roof level against fire wall to one adjoining property, in the valleys of the ridge section, the full width of the property for the sub-roof and around 2 off chimney stacks. Hidden gutters installed between my house and the other adjoining property. (Terrace housing with properties build 30 years apart hence different adjoining style of roofing.)
Not so simple in my case, Phil, with the roof comprising two irregular pyramid shapes, one slightly smaller than the other with an area of flat roof in between! I should also have stated this is NOT going to be a DIY job (I know my limits!) so I'm trying to ascertain roughly what it would cost to get a roofing firm in to do it.
Nearly 3 weeks in my case.
But part of the job was "install 75mm celotex between rafters and foam in the lower 1/2m" which slowed them down. Plus dormer vertical faces (plain tiles).
And we discovered the dormer flat roof needed redecking refelting too.
And this is a fully hipped roof with a very complicated set of flashing plus 4 leaded bays.
I suspect you could get it down to a few days for a simple gable ended hipped roof with no chimney (hell even I could do that).
But many houses, especially ones with conversions can get very complicated.
