replacing flashing

[pennelldj]

Hi Guys
Aany alternatives to lead flashing? maybe something more playable? finding it very difficult to get the lead to sit in the chase... any suggestions?

hit it with a hammer?

bend it first? (with a hammer)

as breezer says, form the lead into its desired shape before offering it up into its final location.

using a lead dresser, you can form a 90 degree lip by dressing 15-20mm of the lead over a long piece of wood. you can form the roof pitch bend by placing the same piece of wood onto the lead and bend the flashing piece towards you, until you have roughly the desired pitch.

offer it into place, lead wedge it, then finally tap it into shape with the dresser.

Would it be easier if I cut the lead into smaller sections? if so how do i cut them and what size would be accepable

Have driven miles to find lead wedges but no one stocks them, know any places online?

Am worrying that i wont get it finished this weekend so what measures can i use to temp wwaterproof it

lead wedges are made from off cuts of lead. you cut off a strip of lead, say, 20mm wide then roll it in a flattened roll. once you have the joint thickness, snip it off and hammer it into place with a bolster chisel. make the wedge so that its snug enough to require hammering in.

be careful if the lead is being chased under a window sill, don't use wedges in this case or it is likely to lift a plastic sill. leadmate cartridge style sealant will work better in this situation.

And do the lead work when it's a hot/warm day, easy to dress it. but having said that we do live in the UK keep it indoors ( next to a rad with a hot water bottle )

Thanks for the tips, one last thing what can i use to cut the lead? is there something i can buy form b&q (the only place open on a sunday now)

A stanley knife/ tin snips, but an stanley knife would be best.

just get a straight edge then run the knife down it a few times then bend it back and forwards until it breaks off.

Thanks Markie - ill give it another go tomorrow in the sun hopefully - the roof is about 3meteres in length and the original leading is in two long lengths - is there anything wrong with cutting them in to more managable shorter strips?

Not tomorrow it wont be

Damn! forgot about it being easter sunday! typical

just remember, do not knock in a wedge at the very end of a run as this will prevent you fitting the overlapping next piece. always keep the wedge 200mm or so in from the end of a section.
