    Slate roof - repair or replace

    The roof looks fine! no obvious signs of nail fatigue from these pics anyway, you've had the ridges fixed? cool - nothing else to worry about here.

    grade 11 roof problem(s)

    30k reduction because of the dubious condition of the roof - therefore I would suggest you get some quotes to replace it - sounds like its about time.

    Badly extended roof

    Nightmare - was it the brickies that did this? - unfortunately no downpipe to hide the join on the roof! Very likely to leak.

    Lead valley replacement

    Sounds like you've had a pretty reasonable price at £850+vat - and using code 5 lead, all the better. Companys that are able to offer insurance backed guarantees would normally charge around £25 for this (sometimes included in the quote). It's a pretty simple thing to give the timbers a...

    Interlocking slates - Sandtoft or Redland or other?

    I think if I was you I'd be more tempted to go for a fibre cement slate - Marley/eternit boast all sorts of eco-friendly credentials for theirs. They are clean, very light, quick and can be easily detailed neatly (with baby ridges on the hips for example) and you can jump all over them...

    Interlocking slates - Sandtoft or Redland or other?

    Both Sandtoft Britlock and Redland Cambriams have had significant problems with uneven colour fade in the recent past, Cambrians being completely withdrawn from the market for a period this year - they have just been pulled off from a regeneration scheme in North Wales as the residents...

    roof gully issue

    Pitched roof valleys should not be designed to be less durable than the material on the roof slopes, they should be designed to weather for longer if possible as they take all the water. Even concrete tiles should last around 40 years, maybe more, so to put in a valley that is not expected...

    roof gully issue

    He he , thought that might get someone's back up - but all you need to do is ask any of the manufacturers of GRP valleys 'How long will these last?' some may give a 20 year guarantee if your lucky, but even if they do last 20 years, c'mon that's not good enough for pitched roofs. They're...

    roof gully issue

    The fibre-cement slip detail is the recommended method both in the Lead Sheet Manual and BS5534 Code of Practice for Slating and Tiling, we have been doing this for many years and it works well. Make sure you use lead compatible sealant for attaching the fibre cement to the lead but only use a...

    roof gully issue

    Needs to be done as described above by Hardmetal, everything else would be a waste of time. GRP Valleys - short lifespan, seems little point in these if you want the building to survive beyond 20years.

    Gully Repair

    Danger Element?? - there shouldn't be any danger element, perhaps his price does include a scaffold though?

    New roof going on - weird slates among other queries.

    For the new roof, would you consider using new Welsh Penrhyn 12x8s ? these would be the same type of slate as the original therefore more in keeping and although it would take longer, it would be cheaper than using Glendyne 20x10s per m2.

    random slates

    Very Brief History of Random Slating: All slates that were quarried before the on-set of the railways and powered mechanisation were 'random' in nature, i.e differing lengths and widths, as they used all blocks that came out of the quarry and split it into roofing slate without trimming and...

    Roof ridge mortar mix

    That mix sounds fine, though personally I wouldn't bother with dye. Just make sure you keep the mix consistent and for best results dampen the ridges first if you can.

    Method statements and risk asessments for lead

    Hello If I can work out how to attach a document you could borrow info off ours if you like, be careful to change any info specific to our company that I may have left in, and take out any stuff not relevant. We have to do these for every single job we do nowadays - I thought that was the...

    Fire break in roof

    Brick it up ? Bricks and mortar are relatively cheap - and it doesn't have to look great! - be careful not to drop a brick through your neighbour's ceiling though!

    Hello, you should always use mechanical fixings for slates, try 'Jenny Twins' these work and are not visible. [/i]

    Survey for possible purchase

    If the roof is not leaking and there are no dislodged slates, then chances are its fine. I reckon most surveyors would recommend removal off the moss at the earliest convenience as moss can dam up gutters and laps causing problems, but these issues will be evident to a competent surveyor if it...

    re-roofing dormers: lead, or felt and slates?

    In defence of lead: It will not be banned in less than 10 years. It would be the best and most traditional option for this detail. It is relatively clean and eco-friendly compared with most other alternatives (especially man-made products such as ubiflex) The lead and other natural...
