  1. Hello, I am looking at suggestions to help finish my loft conversation ridge tiles, from cold roof eaves to warm roof dormer. Either a rubber or a fibre glass flat roof, undecided yet. With an EPDM, I could run it over the ridge and seal it to the tiles and use a dry ridge fix for the ridge tiles and install vent tiles in the eaves. Thanks. Matt.
  2. So you mean, slope the roof back to the ridge? Doesn't permitted development mean any part of the new roof to be below the ridge height? Out of curiosity how would the roof drainage work sloping back?
  3. Hello, I am going through some detailed design of my L shaped dormer. I can make it work with a cold roof, however I have been informed that even with the best ventilation in the world cold roofs will sweat. The chap I am speaking to has been doing flat roofs for many years, it's his opinion and I am sure others have their own experience and opinions of cold roofs, any thoughts on their efficacy are more than welcome. My plan is as follows, if I lower the first floor ceiling and use 100mm deep C16/24 roof rafters and some flitch beams to break up the span in main dormer, I can just about achieve a warm roof. With 100mm PIR above 18mm OSB and 50mm beneath between the rafters. I then plan to wrap the EPDM over the ridge beam and fix it to the tiles on the eaves side to form a watertight ridge, I can then dry fix some tiles above, I could use third round tiles and half rounds at the end cut to shape and with some careful placement keep the ridge level just within permitted development rights. This arrangement would leave me a nice 2300mm head height in the main dormer and 2200 in the outrigger section. So my question is, does that ridge finish sound feasible to you, would building control have an issue with this finish? Also I have used a fall of 1:40 on the dormer and perpendicular 1:40 fall for the outrigger, which means the outrigger has to be lower in height, does anyone have a better suggestion for drainage, perhaps one where I don't lose head height in the dormer. Thanks. Matt.
  4. Hello, I am going to have a go at re-building my front garden wall. It's about 3.6m wide and about 2m on the return to the house. As I have no bricklaying experience I wanted to try it in block as this seems quicker and easier, however the design I want is proving to be tricky. I've attached pics of the looks I am after, which is basically two piers, 5cm or so proud of the 215mm block work and then rendered, please see attached pics and my designs. I've designed the block work to lock in together for extra strength rather then using ties to join piers to wall, you can't see it in the sketchup pic, but the block work bonds into the pier on course 1 and bonds from the other side. Anyone got any suggestions to improve this, how's it normally done and is there an easier way, because i want the 5cm recess at the front it's proving the hardest part and there will be some tricky(ish) concrete brick cuts to form the pier. Thanks.
