    What's fallen off my roof and what do I need to repair it?

    A chunk of render (?) fell off the side of the roof on my single storey extension last week. See attached pics. How should I approach fixing this? It looks like I should be able to just trowel something back on after maybe brushing loose material away. I'm trying to avoid buying a sack of...

    Hi , The boxed in support beam in my kitchen had water coming in. The hole in pic was made to see where exactly the water was coming from (photo attached).
