  1. So is the weight of the slabs causing something to flex or separate and thus it leaks? Are the boards/roof under the slabs firm enough to take the weight of the slabs without flexing? I've had some problems with both flat roofs and paving and had many conversations with roofers and patio layers. I think they say that paving could always be kept two courses of bricks below your DPC as rain droplets can bounce that far and thus breach the DPC. I'm assuming your upstands are in place of a DPC, so they should be higher especially around the bottom of door where there's a chance for water to get in. Is the paving sloping away from the house and towards the drains so that water doesn't pool against the house?
  2. A Henry is pretty good. Lots of suction and pretty cheap. You can get them as Warehouse Deals from Amazon if you don't mind the odd scratch or torn packaging. I use mine for vacuming up after DIY jobs like wallpaper stripping, sanding, etc.
  3. It seems to do a good job at sucking all the moss and dust out of the gutters after a moss clearing job. It probably saves a lot of time if you were doing it professionally.
  4. Roofer came back today and I got him to remove every tile, clean them up properly and refit them tighter than they were before. Also got him to replace mismatching tile with one that matches. Cost him £4.80 for the correct tile. Not sure why he couldn't fit the correct tile the first time round.
  5. You should never use a pressure washer on a roof.
  6. Do you think they're Redland Universal Angle ridge or are they hip tiles? The roof does have a Redland dry verge system fitted, so maybe Redlands make sense? How do you fix this job?
  7. True. It's being marketed as a tool property maintenance companies could use to offer roof cleaning services that don't involve them getting up on the roof.
  8. That's what I thought. They had a man using the claw end of a hammer taking the mortar off but I think he has chipped bits off the tiles and it was probably him that broke the tile. It's a mid-1980s four bed bungalow so access is very easy. Do they still make concrete tiles like those or can you get them from reclamation yards? Thanks
  9. Promised he'd be back on Monday. No show. Not responding to emails. I'm tempted to report him to trading standards.
  10. Those are exactly my thoughts and this guy has hundreds of positive reviews on checkatrade and is trading standards trusted trader approved. I think I've been had. Fortunately, I haven't paid yet and won't be until he fixes it but redoing the whole ridge with the correct tiles correctly spaced, so he'll have to lift the fabric on the roof tiles too and put new stuff on as the screw holes will now be in the wrong place. He told me it was normal to see daylight through the gaps between the ridge tiles. I started smelling something....
  11. It's a metal head that is shaped to the profile of your roof tiles. It comes with something like 10 different profile blades. You screw it to a pole like they use for window washing brushes and run it up and down and across the roof from the ground or a ladder to remove the moss. Removing the moss is ok. It's getting all the moss down to you so you can take it off that takes the time. It cost around £200 for head and all the profiles, which is expensive for what it is. Definitely use a carbon pole not a aluminium one as the weight of the pole will be a problem when you have it fully extended to reach the tiles up by the ridge tiles.
  12. I bought Smartseal Moss Clear. It gets ok reviews on Amazon. I used a Skyscraper on a pole to clear the moss then sprayed the roof with Moss Clear.
  13. We've just had a dry ridge system fitted to our house as the suggestion of a roof contractor who was doing some other work on the house. I'm no roofing expert, but to me it appears that he hasn't fitted it correctly as he has: 1. Left some mortar at the end of some of the tiles so the dry ridge system doesn't grip the tile and instead grips the old mortar 2. They managed to break one of the old ridge tiles and without telling me decided to install a half a new ridge as they said they can't get new ridge tiles of our design now. On this tile they have big gaps at the end of each tile so you can see the black plastic fitting and the plastic clamps that are supposed to hold the tile in place are barely touching the tile, so I am concerned the tile may blow off or we may get rain or snow into the roof space. Photos attached. 1. Does what he's done look correct? 2. Are these big concrete ridge tiles suitable for use with a dry ridge system? 3. How much should it cost to get a dry ridge system fitted? Thanks in advance.
