Just seen your other post, seeing daylight in the roof area does not mean rain will drive through it, providing the roof tiles have enough overlap and the correct angle of the roof then I wouldn't worry too much. Having no roofing felts can be a good thing sometime and its give the roof a good ventilation! All the roofing felts do if you have a broken tile the rain run onto the felt via into the bottom gutter.
