What is the concerte that is on the outside edges below the roof tiles called or what is its term?
When fitting new facia's should this concrete that is about 4 inces in depth going under the tile be removed and replaced with new stuff(its 35 years old) ??
Do you use 3-1 mortar or put sealant stuff in it?
If you replace it is it best to protect by putting those plastic covers you can get over it having replaced it?
