Hi, have an Edwardian semi detached and water occasionally comes through from the valley adjoining the two houses (not shared). It appears that the valley has previously been patched with plastic flashing. Not great. The valley is over 30' long. I'd like to renew this and the options appear to be lead (expensive), a fibreglass gutter lining or something like the Gutterline system. Any thoughts? The pitched roof is relatively new so I'd like to minimise any disruption to it. I have some pics if if only I could work out how to add them.
Many thanks.
Many thanks.
