I'm new to DIY doctor and know very little about roofing, so please bear with me.
I have recently been up in my loft and noticed that the material in between the roof tiles (it's clay-like, might be mortar?) is crumbling and coming down, leaving gaps for water to come in.
I spoke to one roofing company, who said they would have to strip the roof off in order to repair it and put felt up.
Is this true? I have very little money and that sounds very expensive!!
Thanks for your help, sorry for being a newbie at the roofing stuff!
