Replacing flat roof with pitched roof

[steveb1964]

Our flat roof on the garage has had it so I would like to replace it with a pitched roof as we plan to knock into the garage in the future to extend kitchen etc.

The garage is attached to the house but the garage wall is only a single skim brick wall with 3 pillars.

My question is will a single skim brick wall be strong enough to take the weight of a tiled pitched roof?

Would I need to get a structual engineer to have a look?

Thanks

I doubt its strong enough IMO.

I doubt its strong enough IMO.

would a builder be able to make the decision if they had a look or would we need a structural engineer?

As this work is notifiable and subject to Building Regs Approval you could do a lot worse than phoning Building Control. They may be happy to pop out for a quick visit. If you talk it right, you could dig a hole beforehand and get him to peer inside and take a look at the foundations. Its only what an SE would need to do anyway. Unless you get a good builder who has good knowledge of local houses and is familiar with the type of foundations likely to have been built he should advise you to do the same.

 

[roofers]

A pitched roof is a roof for which one or more roof surfaces is pitched more than 10 degrees
[1] and alternately a roof with two slopes that meet at a central ridge.
[2] Some definitions are even more general, including any roof with a sloping surface or surfaces.
[3]The term roof pitch (in roof construction) refers to the angle of a roof from the horizontal. The word pitch can also be used as a verb, i.e old roof framers refer to having to "pitch a roof."

A variant of the pitched roof is the lean-to roof, a roof structure where the roof leans to one side of the house. Rafters are connected to the highest wall which are declined to a lower wall. The rafters are often connected into the wall individually or even supported on a wall plate bedded within the wall. This type of roof can have no joist at all or have a tie or have a joist with a strut to give more strength.
