Should I insulate my loft between the ceiling joists or the roof rafters? Or both?

Hi, we are currently renovating our house (bought 3 years ago )and building a extension to our kitchen (build notice/permitted development). Part of this involves replacing the current grp roof ( which has failed and leaks ). We are semi detached and our flat roof backs on to our neighbours flat roof on the party wall. Their roof is currently 6 inches higher than ours and the joint laps over our roof . We spoke to our neighbours yesterday and informed them of our intention to replace and raise our roof level to give us a little more head room in the new kitchen. They have said that we cannot do this as they a have a lifetime guarantee on their roof and that is if we alter the overlap it will invalidate their guarantee. Is this true? Also do they have the right to refuse permission? Finally as we are intending to raise the roof, would this come under the scope of a third party wall notice? Thanks in advance

What does it cost to repoint a chimney stack please about 6ft tall on a bungalow

Want to replace the flat roof on a double garage (measuring 5m by 5.5m ) with fiberglass material (CURE IT). I will also require the roof boards replace. What will it cost?

Hi, We have a leak coming through to our living room ceiling from the flat roof/terrace above. The terrace is currently covered with felt and water pools. We have had a number of trades come around to quote to resurface the terrace, most have said they wouldn't replace it with anything else other than fibre glass which we can't afford. One company has suggested removing the felt, adding a bitumen layer, PVA and then self-levelling compound with a 10mm drop/slop so the water drains off. Around the edge of the terrace they will install edge panels with waterproof sealant. Does this sound like a suitable fix as I'm nervous about paying the money to find its not fit for purpose at a later date. Many thanks Nic

Is it good practice to fit step and cover flashing to go over plain profile tiles (Terreal clay) rather than use traditional method using soakers and flashing not showing over tile?

I live mid terrace my neighbours have had a new roof. The tiles are different to ours. When the scaffolding came down there is a uneven gap from ridge to gutter. My side has nothing to keep the tiles lifting and I’m worried about rain and the wind. What can I do

How much it would be to remove one chimney stack that's not in use, install new lead flashing around shared chimney and concrete the flaunching? This installation is on a shared chimney stack. Additionally, how much would it cost to re-render where there is evidence of some cracks? Many thanks.

Hi, I'm currently having a new roof and porch put on, but am unsure about the finishing steps at the interface of the tiles and rendered wall. The roof interfaces with two timber dormer cheeks, and one masonry dormer cheek, all of which will be rendered once the roof is completed. Currently, aluminium soakers have been installed under the tiles, finishing against the wall/cheeks. My question is: 1) should a flashing now be installed on the wall/cheeks, overlapping/protecting the soakers, with the render then bought down to slightly overlap the flashing and the edge finished with a bell bead. Or 2) Should the render bead be installed directly overlapping the soaker, and not bother with the flashing? Have looked online but can't seem to find a definitive answer. I'm a bit concerned that without a flashing there's a risk of issues in the future which will then mean having to hack the render off! Thanks for any replies.

Hi. We recently got a small extension roof insulated with 100mm insulation boards and plasterboards on top. The guy doing the work said we could heighten the ceiling, by removing the collars that tied the two rafter sides together. He said that cause it was a small roof, that there’s not much weight and we don’t live in a climate that has much snow etc so that it would be fine. Job is less than 5 months old and the cracks have started appearing in the ceiling running along several lines. Just wondering were we fooled and if he knew what he was talking about or will our ceiling eventually collapse?
