small roof extension (for recently built garage) which meets the existing roof on 2 planes. On one plane a new valley is formed while the other plane is simply a continuation of the existing roof line. It is a hipped roof and new roof is hipped also. Tiles have been parted/removed on one plane...

...example of the gutter/valley setup i'm attempting to describe/create: [/img]

.

this is very good advice, many thanks. ironic really that my approach to this job has been governed by roof carpentry and forming, just had an 'ok' over the fone from the roofer/lead man that he'll come for a day to dress it when ready. the carpenter mentioned code 4 lead, which i'm familiar...

thanks, any can you point me to a site that sells this rubber product in kit form? also seen some glass fibre kits that look promising, couple of rolls of material and a a tin or hardner/contact adhesive - anyone had experience of this product for a gutter/valley of this type? cheers.

thanks for the detailed advice, looking at the job the max sole width might well be greater than 500mm, but this might be due to the fall i've anticipated, which is 1:40 - you mention 1:80, is that fall considered suitable for this type of gutter/valley by the BCOs? tbh, reducing the fall to...

thanks - do i still need to form the valley with ply first?

recently had a small extension built with roof carcassing, the roof is hipped and sits parallel to another small hipped roof. i need to form something like a 'box gutter' to drain surface water away but obviously there is no fall at the moment. (roof carpenter told me it needs a 'box gutter'...

??? i called 3 guys on the gas safe register who live in my local area, he was the only one who turned up to view the job. anyway, how am i to know if someone is a 'good installer' - i can only see the work once it has been completed! has the guy made a mistake with my system? (the rads...

Hi, Guy installed full system to my bungalow last week, combi and 10 rads. nice tidy job, 22mm flow and return running around the loft, teeing off down walls to rads in 10mm pipe (chased in). all done in barrier pipe. Been up there today and can't see any bleed/air vents anywhere - going to...

distance from mixer to location for oversite is about 6 feet! how many bags of ballast and cement would I need to mix 1.8 cubed? or is it more economical to buy sand and gravel individually, rather than ballast?

thanks for the advice folks, i really wanted to do away with having 100mm of oversite as the foundation crete was pumped in at considerable cost, due to tricky site access. to have mr.concrete return with pump for a poxy 1.8m cubed of oversite would make me cry! will speak nicely to the bco...

i have the opportunity to choose either of the above systems for a small 1 room ground floor extension (18 sqm) - was all set to go with timber, but the bricklayer is trying to sell me beam and block. He says one of the advantages is that no oversite concrete will be required with b&b, just a...

..the builder tells me 100mm cavity is now standard. However, I've seen some plans lodged with my local authority that specifiy 85mm cavity. Meanwhile last time I extended 75mm cavity was used! The inner skin will be aircrete type lightweight blockwork, does the combination of inner skin...

many thanks for the tips! for some reason the skip hire contact estimated 6 cubic metres of clay soil will equate to 20 tonnes in weight, meaning 3 eight yard skips would be required. however, judging from responses this is a bit excessive, and use of mechanical devices to compact the...

this is where i excavate the trench and dump the spoil in a heap on, say, my driveway and the grab lorry comes along to scoop it away? is this more cost effective than skips for getting spoil offsite? Been qouted 100+ vat per 8yd skip.

I have a trench to dig for extension foundations, have called two skiphire outfits and received conflicting advice re muckaway: One firm stated 3 8yd skips necessary, the other between 8 and 10 8yd skips! Where they differed mostly was in how much the waste would weigh and how much it...

drain cctv was ok, water meter reading not budged for 2 weeks while away over xmas period. rules out 2 possible causes of damp! i have been made aware (by a local tree surgeon) that the neighbourhood has a high water table, which peaks in february. There are known to be underground springs...

yes this is the worst case scenario, which tbh i am prepared for. will research costs re getting a floor core sample analysed. assuming the floors are replaced, how are the internal walls treated? is a chemical compound injected into the base of internal walls once the slab and infill...
