Flat Roof Balcony Fiasco
Comments (12)Hi - been there done that! Start again! OK I can see there is enough clearance below the door to allow a decent fall to be created if its not enough already. This can be done using pressure treated timber firings which are essentially lengths of timber cut and tapered to dimensions according to a plan such as my example below (I realise your balcony is much smaller but you should get the idea). My firrings plan and cutting list shows 3 drain points with the firrings mitred to created falls toward relevant drain. Your local timber supplier should be happy to cut these and pressure treat resulting tapered timbers which would be fixed at 300 centres max and would have 20mm min marine plywood screwed on to them at 150mm centres. OSB 3 roofing 'chipboard' which can come in tongue and groove form would also work, I just prefer ply. They need to be planned out so that the fall of the timber firrings sends any water toward the drainage channel (if there isn't one then create one) or to the edge of your balcony where the rainwater gutter will collect it. Then use RESITRIX - we used this supplier, but there are plenty out there.... http://www.rubber4roofs.co.uk/shop/epdm-rubber-roofing which is a much stro nger version of EDPM rubber and can withstand foot traffic as it is reinforced with fabric making it almost like a wet suit - its a fantastic quality product believe me!. You paint on a black primer on to the ply, then peel the backing off the RESITRIX and apply. Be warned - as experienced people (but not exactly specialist roofers) we managed to do this very effectively, but found that extreme care is needed before committing as once the RESITRIX makes contact its sticks forever!! this is especially difficult at internal corners. Only peel back the backing plastic off the RESITRIX rubber a little at a time as you need to hold it up off the deck to ensure it doesn't make contact in wrong place. two pairs of hands can help!!If you have planned the falls correctly so that the water is sent to the drain, you will now have that long awaited water tight balcony! Now Google 'tiles for decks and balconies' and you will find no end of options of special porcelain or ceramic tiles with plastic adjustable feet for each corner of tile which allow you to place the feet and tiles level on top of your RESITRIX flat roof with no risk of penetration pif the rubber. Water goes between the tiles as they are not grouted, just placed on the feet. Not sure if the tiles you have will work without cracking - you could test this by standing on one which is supported only at corners. by the way RESITRIX happens to be one of a range of flat roof solution I have used including Kemper liquid rubber system (which is reinforced by a fleece like fabric which is simply rolled out onto a bed of liquid rubber then soaked on top with more rubber) Messy but effective, a similar process to GRP. Have also used one piece EDPM rubber which a very competent DIY'er can fit. A very economical and speedy solution, but not good for foot traffic - although they are starting to introduce reinforced versions. We are actually going to use slate grey plastic/wood composite decking http://www.wpc-decking.co.uk To do this we will PLACE a new set of firrings on top of the completed rubber deck but also will stick strips of RESITRIX to underside of firings for protection. now we will have a deck that can be lifted for maintenance in future if required. These firrings are the opposite of the ones used to create the falls, which brings the deck back to level of course! In reality we will actually adjust to maintain a slight fall so that, and the gaps in the deck takes water away. A long answer - I hope that it helps! Best of luck!

Comments (4)It’s quite difficult to see from the photos as the scaffolding is still up and we have mahogany windows which are very dated and I don’t want to keep. The fascias around the roof are black but I feel that the fascia is so large that black will be too huge and stark. I’m feeling in a dilemma. I hope the photos help a little....See More6m rear extension layout and roof light ideas
Comments (20)I think the above comments are all really valid regarding sloping the roof of the extension and joining the existing and new with glazing. This is a really nice way to bring some light into the middle area - adding a window here is also worthwhile if possible if you are end of terrace. The Planners may allow you to have a view out as well as light as long as it is not overlooking. Your current lantern location also doesn't align with either the dining table or island, which may look a little off balance. Also remember to consider the location of any lighting so it doesn't clash with your glazing; pendants and spotlights as these will be what give you ambience and should provide atmosphere and task lighting. We did a similar project recently, extending an existing victorian terrace to house a kitchen/diner. We actually added flat roof lights along the long wall, giving natural light and views over the kitchen workspace and dining area. Would you like a half hour interior design consultation for some friendly one-to-one advice? We have a couple of slots each week for £125+vat. The consultation includes a friendly video chat to talk through your space and discuss your project ideas and needs. I follow up the video call with digital moodboards tailored to your budget, a layout suggestion and product recommendations. I will also follow up with a phone call....See MoreAlternative to flat roof for 5m rear extension
Comments (13)I'm sorry I'm just not following. Do you mean the space between the two roofs? If so, that space doesn't need guttering. It will form a gully with a hopper at the end to collect the rain water. Also the water collected from the faux roof on the side of your neighbour will be negligible so if it runs on to his roof that is not a problem. We live on a hill and there are a number of properties on this road that have rain water collected on a neighbours roof. So whether you have a gully or not I can't work out how that will decrease your interior space....See MoreUser
