Yes I see where you're coming from but the tiles at the low end will be to low. I haven't got a laser level, the water level is more accurate than the laser level anyway. Cheers.

Hi, No I haven't done the string line yet as it pouring with rain, I assume the string line has to be set level? From my measurements the rafters are 20mm out over 6 meters then 6-7mm out over the other 3 meters. The blockwork, wall plate and ridge board are all level give or take a couple...

I'm going to, but I want to be sure about what I'm talking about before I do, so I don't get fobbed off. He's obviously mucked up & in my experience people don't like to admit this. I can't see him taking the roof down & starting again can you? so I'm trying to find out if there is an...

Hi, the roof is a low pitch to start with (Tiles at about 17 degrees) so at the end where the rafters are low this is going to cause the tiles to be at a much lower pitch. Edit.... Just had a better look while dodging the rain showers, the rafters aren't all at the same height above the...

Hold on there... what's that all about? All I'm saying is that even if the walls weren't parallel there must be a way to get the rafters all at the same level, I'm not questioning woody's experience I'm just wanting to understand this. Cheers.

I think the birdsmoth cuts have been done wrong, some deeper than others hence the height difference. Even if the walls weren't parallel (extension out of square) I would have thought that you should be able to get the rafter heights the same? Cheers.

Hi, Do you mean with the string line set level or just following the rafters? The 26mm measurement was taken plumb above the outside brickwork, I used a water level to measure this. Cheers.

Hi, Sorry, the one detail I left out was to mention that it is a pitched roof. Thanks.

Hi, I have just noticed today that the rafters at one end of my lean to extension roof are 26mm lower than at the other end, the roof is 9 meters in length. Let me explain... I had the roof timbers on my ground floor extension fitted by a joiner about a month ago, the joiner was...

Hi, Yeah but if you look at the wessex tile it is only raised at the interlocking bit, so you have a large flat area, the comb spikes will be totally folded over along the flat part and the spikes of the comb will probably hold the tile up a little so it would probably be best to cut the spikes...

Hi, Thanks for the reply. Have decided to go for the 96mm headlap which I'm sure will be fine, I have the Eaves protectors (felt support trays) so will be using those along with maybe some comb filler. I'm not sure if the comb filler is the best choice for the Wessex tiles as they have a...

Hi, I've worked out the gauge of the tiles and I can either go with 8 rows of tiles which will give an approx headlap of 96mm, or I could have 9 rows which will give a 132mm headlap. Can anyone see a problem with using a 132mm headlap? The bigger headlap looks like it will work out better...

@ tomsully67 So did you sort the roof in the end ?...it would be nice to know. If nothing more, just so there is an end to the thread that could help others, Cheers.

The building inspector told us that the wall between the garage & utility room (classed as a habitable area) could be a stud wall with 75mm kingspan or similar inside the wall (between the studs) & 25mm covering the habitable side. This is to eliminate any cold spots from the studs. The...

Thanks for that :)

Hidden brackets? never heard of them, do you have a link to them as I can't find anything about them? Cheers.

Yes any ordinary portland cement should be roughly the same colour but not all are, Mastercrete in my experience produces a light mortar. In a lot of cases it doesn't matter if the mortar is a shade lighter / darker, but if you're trying to match a mortar the cement chosen could make a World...

Whilst I agree that roofs will weather down quickly and that the colour of the sand will play a big part in the finished colour of the mortar the cement should not be overlooked, not all cements are the same & some produce a much lighter finish than others. I've just been through the "Cement...

Beware of light coloured cements like Mastercrete, depending on the sand used you could end up with very light mortar which stands out like a sore thumb on a roof. Cheers

Hi, The tiles being used are Marley Wessex, unfortunately there is no tile & a half is available, good thinking though :wink: http://www.marleyeternit.co.uk/Roofing/Concrete-Tiles/Wessex-Interlocking-Tile.aspx Cheers.
