Never fixed dry verge units before but having got my head around the installation instructions yesterday I can see they can also be retrofitted. On the r/h verge I nailed a tile at eaves course, fitted plastic unit over, repeated upwards until reaching the ridge. Real issue I've had is with...

Looking at the interlock on this tile (redland grovebury), it will be awkward going left to right. I'll give it a go and make a decision whether to continue or go right-left instead. I've noticed pro roofers strike out lines with the ink, but this is diy! I have made a pencil mark on battens...

...started with stacking out this morning, five in a pile located over rafters. Not much fun. The tiles are specc'd to be laid from right to left. However, where verge is on the left and a valley on the right hand side of the roof plane, do I just do left to right instead? Or should I string a...

This is my first attempt at roofing. Noticed roofers stack out tiles on a roof in a particular pattern, before fixing. Is there a standard way this stacking is done? I have large format concrete tiles. Planned to stack 4 max, and only where a rafter gives support underneath - sound ok? Also...

Cheers - Had half a sheet of 18mm ply in the garage, so attempted the inlayed boards, as per noseall's picture. Been subjected to several heavy rain showers today, meaning most of the time been spent uncovering / covering the exposed roof void, just to get / weather proof at the valleys :cry...

Great tip - cheers. Sketched out some designs and using your extended nogging idea think it's possible to work it so there isn't any 'step' due to the ply... Tile battens on site are 50x25. If 6mm ply used, cut 200mm wide strips (grp valley unit is 400mm wide). Support with 4b2 nogging on edge...

Sorry I neglected to mention the ply would be supported on noggings - noggings are specified for support under the ply in the grp dry valley installation instructions. I'm tempted with the ply over rafters option because the noggings will be much easier to cut and fix, when compared to inset...

Pretty sure regs state soakaways should be minimum 5m from a property these days, which would mean lots of trench digging for you. But as CB states, they are useless in clay soil anyway. Depends on whether you get LABC involved, if not then guess you can do as you like. I once dug a soakaway pit...

On my bungalow extension I parted existing roof tiles and fixed diminishing trusses up the rafters (what a nightmare that was). The trusses are at 600 centres, existing rafters are at 400 centres. The roof intersection new to old forms two valleys, each 7 metres long. Each roof structure has...

Ok, thanks for shedding some light. SE's calcs doc states: 'By inspection provide engineering brick padstones under both ends of beam.' This spec applies to a 203x102x23kg UB steel, span 3600mm. One end of the beam is to sit on the inner leaf of an extension (thermalites). Other end...

SE has commented on plans to give load bearing beam '100mm bearing on engineering brick'. On a previous extension job I built up three courses of engineering bricks in a section 450mm wide, into the inner leaf block work to support a beam end. BCO didn't comment, so assume that was good...

...to elaborate, I'm currently adding an extension. On external walls earmarked for render finish, if I match positioning of drip bead as per the existing building, I will need to source approx 60 facing bricks to form the course between dpc and drip bead. Unfortunately my local builders...

My 60's bungalow has a few external render 'panels', I can see the drip bead is always positioned one course above dpc. Looking at neighbouring properties, the drip bead is at least one course above dpc too - sometimes 2 or 3 courses above dpc. All of the neighbouring properties have 3 or four...

Thanks for replies. Existing roof is 22.5 degrees at best, the concrete interlocking tiles have only a two and a half inch lap. Reading tile manufacturers websites there is no way this configuration would be recommended nowadays, yet the roof covering has been in place without any issues...

Have a proposed single storey side extension and due to the span (wall plate to wall plate 10350mm) the truss company drawing shows a pitch of 15 degrees, in order to keep the roof at/below 4m height (enabling permitted development). Found a couple of products suitable for this pitch but on...

...problem must have been with my technique when fitting the bung, getting it perfectly square inside the 110mm pipe before tightening. Test has held for 2 and a half hours now. After the first 30 mins water level dropped 2cm, then stabilised. I'll give it another half hour but it looks like...

Had a specialist in to do a full refurb / re-enamel on a cast iron bath at a previous property. He spent an absolute age on preparation. He used various attachments on a grinder and different grades of wet or dry. Applied the enamel, finally painted the underside with metal oxide paint. Looked...

Cheers for the advice. Reading through previous forum posts, seems it's not uncommon for a drainage system to pass a water test and fail an air test, with the major point of failure being the air test kit itself! Therefore not convinced of the value of heading out to buy a kit that might be...

BCO inspected today and passed the underground drainage system from a regs point of view, but advised I do a water test, as they will want to do the official drain test immediately prior to occupation. 10 linear meters of pipe runs under what will be a ground bearing solid floor, and he made the...
