Mono Ridges

[Andy Roberts]

My neighbours and I have knocked down our old outbuildings, we have decided to render our side and neighbours are building a new larger outbuilding out of breeze block with mono pitch roof.

The builders have used mono ridges, but they protrude well over on our side of the party wall by 3 inches.

Is this standard roof construction for a monopitch roof on a party wall? I would of thought at worst, the rafters would be cut level with the edge of the party wall, then only batten and ridge tile would stand proud to provide a drip edge.

• Would the better of option of been building up the brick course and use a wall plate for the roof?
• Is is acceptable to have monopitch ridge tiles encroaching on party wall, is there an alternative?

Looks cr*p , I cant see exactly what they have done. but I would have thought they could have adjusted the top course of tiles etc some how, then flashed in lead down over the original ridge tiles used as a coping.
TBH it would not have been more expensive as mono ridge are not cheap.. Awful!

Yeah a crap job. They have tilted the ridge, not laid the vertical edge vertical.

The minimum projection should be about 20 mm, the thickness of the tile. Sometimes a bit more if the roof is ventilated.
