Hi Chaps, My Granny (89 Years Old) has a garage with a flat roof which is leaking. I had a look at it yesterday and its knackerd. The roof rises and falls along the length and water is pooling in the low spots and its leaking in. At some point in the past its been covered with some sort of tar and had grey gravel spread on it. Its the black tar thats breaking up and letting water in i think. She has had a few quotes but quite rightly all the tradesmen want to re roof it and the lowest quote was £2000 plus VAT. She quite simply doesnt have the money to pay this. She also refused to let me pay for it but has agreed for me to try and fix it !! Now my plan is thus. Sweep off all the old gravel then screw sheets of 12 mm weather proof ply over the whole of the existing roof packing, up where the low spots are. I will then use some sort of bitumen to cover the boards and also glue down sheets of new roofing felt and nail it down with clout nails. Couple of questions. Firstly will this work and last at least a few years? Second what can i use to glue the felt down, i was thinking some sort of bitumen / gloopy black stuff ? Third will shed roofing felt be sufficient or will i need something a bit more heavy duty ? I dont have a big blow torch etc so any fix must be done without pro tools. Also i dont want the joints in the felt to let water in so someway of sealing them will be required. So what do you reckon guys ? Is this doable ? I know ,and she knows, that this isnt a long term fix but as she said to me today ''I wont be here in the long term so what do i care'' Comments welcome Cheers Alex
