Two experiences of valleys.
In one cause it sloped teh roght way, and still leaked very badly.
On my new house I have two very fierce valleys - with big slopes - but
the issue is the people who leaded it carried the lead way up under the
tiles and thatch that abutted it. What may be an issue for uou tho is
that they only leaded it ion shor sectioons - about 2 meters, and then
overlapped it =- app[erantly long runs camn tear in cold wetaher due to
If you have a tear, or indeed an overlap, on a long FLAT run, standing
water is going to seep into the timbers.
8ft is probably on for a single length of lead, and if its been done
properly, with no joins and carried well up, its not going to hurt in
the slightest, if it has ANY joins or holes though, its asking for trubble.
