Hi guys.

Was talking to our neighbour this afternoon and got onto the subject of our shared roof. We live in a 3 bed semi (as do they, joined to us.). We both notice our roof could do with replacing.

Our neighbour said we could get it all done at the same time, which will work out cheaper and easier for both of us.

Has anyone had experience getting a new roof?

Whats the kind cost would we be looking at for a standard sized 3 bed semi?

Any comments appreciated.
 
What do you mean by new roof? Is it sagging, slates missing, ridge tiles missing?

My roof is over 100 years old, and the slates are still fine - but the timbers underneath could do with some attention. If the roof was to be overhauled, I'd have a membrane put under the slates, and the timbers replaced - but the slates are fine to reuse.
 
Totally depends on specifications and scope.

Nice clay handmade tiles, Welsh slate or cheap concrete interlocking? Timber work? Verge detail? Ridge detail? How much lead work? Chimneys? Access? Hips, ridges and valleys?
 
Well all the cement is coming out of our ridge tiles, mine and my neighbours, we have numerous cracked tiles. The lining in the loft needs renewing as its got lots of rips and holes allover.

I guess the main timber framework is in decent order, but it would be for a full set of tiles and whatever wood slat things involved.

Want to take advantage of the fact that the neighbour is keen to get it done, because in the future should they move out I might not be so lucky.

and in response to Macca, I figure cement tiles (cheaper?) 2 ridges on my side, 2 on their side. Standard 3 bed semi. No hips or valleys. Chimney will need flaunching and pointing when up there too I think. Access will be a scaffold around the entirity.
 
All depends on the type of the tile you have got on the roof. If your looking at a "standard" Marley or Red Land type tile with a breathable membrane, new battens, 2 hips per property and new leadwork to the chimney and scaffold I reckon your be looking in the region of 5k-5.5k +vat per property.
 
Lots of roofs are now buggered that had slate and replaced with concrete tiles. The timbers aren't designed for them. Be warned.
 
Some good replies thanks.

I suppose I should just expect anything up to 5k.

Its a standard 1930s semi. The roof just looks pretty standard to me. if it was all coming off and being replaced with new then I guess we would to with something mid range.
 
I had the roof replaced on my last house about 5 years ago. That was a 1950s 3 bed semi and the roof was falling apart. All the mortar on the inside had dropped away, you could see daylight through the tiles, it leaked and some of the jack rafters were rotten. It cost me about £3k all in for new tiles, membrane and to have the rotten rafters replaced.
 
Get some roofers round!

Definitely take advantage of a neighbour who is up for getting it done at the same time you will save money, get a better looking finish and avoid the vertical gutter at the join which can be a nightmare!

For a straight swap assuming it's fibre cement slates then probably looking at 3-5k

You could keep patching it up tucking in slates repointing ridges etc but the costs quickly mount up we got bored of spending several hundred quid every year or two and had the whole thing done which hasn't been touched since it is such a relief not worrying about water leaks everytime it rains!

Just want to echo this.

We're going to have our roof done (timbers and all) at some point in the next few years due to this.

This is what has just happened to my next door neighbour's roof. It was caving in, so much so that even the plaster in the bedrooms over the windows was dropping off. They have just had some new beams put in last week. Scaffolding is still up.

In terms of weight slate is normally slightly heavier per square metre than concrete tiling. This is due to the increased number of slates required per square metre to form the correct headlap (natural slates do not interlock). Concrete tiles have interlocking edges and require less headlap, thus whilst they are individually heavier you need less per square metre. The heaviest roofs are usually either rosemary tiled roofs, or natural stone slates.

These are 100 year old terraced houses with slate roofs. Mine is still the original roof and apart from the odd repair due to slipped slates, everything is fine. Next door roof was replaced with concrete interlocking tiles (probably in the 70s/80s). Their roof was bowing in where the roof meets the brick wall.

Yeah this isn't right at all even though you said thus

Sorry.....to clarify, I must stress when I said normally I didn't mean all. Clearly, if you pick a particular slate with a very thin gauge then you can reduce the weight per square metre substantially. However, on "average" the difference in weight is negligible between a concrete tiled and a slated roof in most instances. To be absolutely sure though it is paramount that the specifier of any replacement roof covering undertake a thorough survey in the first instance where a proposal to change the roof covering material or unit size of a natural product is to be carried out.
