Recycled Timber and Roof Sheeting build a Verandah
Recycled roof sheeting came from the old roof, removed from existing flat has a shiny, clean underside which is the side most visible in this situation.
The idea to create a wood channel to slide the recycled roof sheets into, drew warnings from some professionals:-
“Secure the roof sheeting from howling winds…so we did 😊”
It slopes down from left to right, secured by 100mm screws into ‘4×2’ [100x50mm] wood frame of the Sustainable Co-Housing tiny home’s new living room.
The recycled bottom timber of the 3mm channel is a 90x50mm solid 3 metre timber. The top timber is off-cuts which have been slit down the length of huge recycled timbers used as window lintels.
The slight slope will ensure swift exit of rain.
Long batten screw holes through the ancient hard jarrah were pre-drilled, with small piece of roof sheet to measure off on the long 2.15 metre sheet so that holes would line up.
Sheets are not full length so that roofing can be removed easily at the end of summer, to be replaced with clear alsynite for winter sunlight 😊 The three 1/3 length sheets snugly slide into the channel, with tek head screws at each end. The little white ‘eave’ made from re-used old roof flashing is replaced in this picture. It was released at the tek screws at base of cream Colourbond barge board in the earlier picture to make space for the drill.
Shown right are 65mm screws holding each valley of the sheets on cross struts spaced at one metre intervals, which are seen clearly on next photo.
Solid ‘4×3’ recycled jarrah pillars [100x75mm] bolted onto 100mm stirrups set in concrete that was poured into a metal box made from left over Colorbond old-roof flashing.
We get to look at the shiny ‘new-look’ bottom side of the old roof sheets which were sheltered for all those years. The sheets were used to make safe walkways on the old roof, collect the mortar from to raise parapet and side brickwork 7 courses above the original flat roof height, before being brought down for reuse.
Why throw anything away? Recycled materials save money and the environment 🙂
Ground slope underneath drops 400mm over the 3 metre ramp from a 3.2 metre flat section at the far top outside double glass doorway and adjourning full-length window.
Top of pillar rebated to cradle the rebated ‘4×2’ long horizontal beams.
Close up in next photo which shows how the turned-up ridge prevents heavy rain flooding up the slope.
No overhang as another pergola will come toward us from the original flat in the future.
Roof sheets are joined with metal screws as shown in the next photo😊
Overlap of 150mm to ensure no back-flow in heavy rain. Some silicon used to ensure no leakage – even in the big storm on 17 May 😊
The darker green-grey Colorbond is reused old-roof side flashing now creating a small eave to protect water running behind wood channel, and later protecting rendered strawbale walls extending above verandah roof.
The little leftover gutter from the main house catches all the rain too.
The outside pillars line up with double doorposts, and adjacent same-width full-length window,
and
it lets in the May sunshine as shown in the bottom photo 😊
Who says you can’t build with recycled materials? 😊
