30s semi with no roof lining. Looking at options for breathable membrane vs spray foam vs anything else. Pros and cons to both so far and not sure who to believe. Will probably go DIY.
Any products/services you'd recommend?
Property also has a flat roof extension c 20yrs old, therefore looking to proof it. New layer of bitumen or slop on some liquid (no leaks/tears in current felt). If roof unsafe to walk on then is it a case of laying planks across for access?
Again, any products etc?
