Browse Forums Outdoor Living 1 May 02, 2015 12:31 am Hello DIYers! I would like to build a verandah similar to this: It will be attached to the fascia at the back of my house. I'm building it using timber frame and zinc aluminium roof sheets. I initially wanted to do a flat verandah but I really like the look of a gable in the middle, similar to the picture. There are two things I'm concerned about though: Since I'm using a timber frame, how would I cover the triangle opening on the gable closest to the house? Would I need to use some form of roof sheet as well, and cap it all around the perimeter of the triangular shape? I'm just really concerned that it will leak underneath into the door area. Would I need a box gutter in between the verandah and the existing house? Or would I just need to lay the roofing sheets below the roof tiles of the existing house, so that any rain runoff will fall on the verandah roof and into its eave guttering. Please any feedback would be greatly appreciated. Thank you so much. Kind regards, Noah. Re: Flat/Gable Verandah roofing and guttering 2May 11, 2015 9:20 pm Hi Noah, Realistically you could install some kind of metal sheet/roof sheet or you can use any other cladding. A good option might be framing out a 35-45mm (triangle) wall and cladding it in cement sheet/blue board or something similar. That way you could clad the inside with cement sheet as well to get a nice flat painted finish on the inside as well. (I've always thought a window/Perspex would be good to let more light in but cleaning may be an issue). A box gutter is probably a little over the top but if your concerned I would look at getting the lower roofs to fall to new gutters on the sides not to the existing gutter/roof. That way there is no additional roof load to the existing gutter. With a low pitch roof sheet it won't affect your ceiling height either. It can work really well. Re: Flat/Gable Verandah roofing and guttering 3May 29, 2015 12:50 pm The way I would do it is to not have a gable at the back at all meaning no box gutter. Just continue your ridge rafter all the way back to where it meets the existing roof. That way you end up with a valley gutter on both sides however you will need to trim the existing roof sheeting to suit. If you were going down this route though, I'd employ a carpenter to do the framing.

I wanted to make sure there was no heat trapped against the house, and leaving it open seemed to make sense. The other alternative I was thinking was if the ridge didn't overhang the roof I was going to install louvred planks to still allow the breeze through and hopefully block out the rain. Ours was a west facing patio between three walls so ventilation was important, to me anyway. Re: Flat/Gable Verandah roofing and guttering 5Sep 03, 2015 8:23 pm Rear infill options are usually: - Polycarb sheeting horizontally in Corro - Twinwall Polycarb - FC sheeting The first 2 are the best due to light transmission with the CGI polycarb being the cheapest In terms of construction: Adjustable Rafter Strengthening brackets to attach a header beam to then build the gable off. Box gutter at the back is the best option so you do not have a leak point along the length. Look at the installation instructions from someone like Stratco for their Steel versions and that will give you an idea for building it out of timber. Yes, get a builder, make sure he is experienced and a registered building practitioner 5 8988 I would say both styles you have pictured are steel. The lower chord of the first pic would be a massive lump if made using timber considering the size of the rafters. If… 1 6183 2 9479 |
