A series of questions and answers relating to Slate Roofing
Can I put a window in a natural slate roof?
Yes! All roof windows have appropriate flashing units for all types of slates.
My lead gutter keeps leaking it has a crack in the centre which I have repaired on numerous occasions what is the best way to tackle this problem?
It sounds like the section of lead is too long and not the right thickness, it is common were thermal movement in lead causes the lead to crack this is where it has been formed incorrectly.
A new gutter should be formed from the correct code (thickness) of lead using the Lead Sheet Association regs; if the gutter is very long then expansion joints can be welded into position.
