DIY Build roof at side of house.

Hi all. I am considering building a roof from my existing house to a boundery wall, i.e the area you usually bring the lawn mower down to acess back garden, its just wasted space. I have already build on the opposite side of house a sloping perpex roof, its quiet tidy and does not leak. My issue is I want to use this roof as a possible storage/workshop so I want it dry and warm. What is the best design, sloping or flat. I have thought about the roof and guttering, but need more infor from soem one who has done this. I am thinking of placing the guittering on the wall itself and trying to maybe place a plastic membrane so I dont get any moisture creeping under it...any advise would be appreciated.

Well that was a lead balloon lol, its okay, I will work it out. Google is king!!

I've been wanting to do the same job at my place dude, let me know what you find if you can as I really want to do this for the same reasons as yourself!

If the boundary wall is shared with a neighbour, that means your gutter will be on his side of the wall, which they probably won't like. Best to have a chat with the neighbour before you go ahead.

A sloping roof is best, yes. You'll need flashing on the house side of the roof, might want to get a good roofer to do this part. (Best of luck with finding a good roofer, by the way)

Hi Thank you lads. I have built a fine Timber frame complete with wall plate on boundary wall with neighbour (good point, Extopia, ask neighbour and I did). It was quiet an enjoyable build as its all timber looks neat and Perspex is easy enough to fit. The Guttering again was handy to do, when you have the other wall plate mounted on the boundary wall, you simply attach to the side of it the guttering hooks/supports (put some Perspex on roof to make sure the water spill be level). I did the whole 25 m's for approx 250 Euro. Local wood, local Perspex. Elbow grease free. Now I want to build on a side with no neighbour only a road, this time I wasn't to use its an office/play area so need some dampness/leak issues taken into consideration. Thanks for the advice.

Kohhal, yep man what you need to know, I have found no probs with building a safe secure, attractive (for want of a word) perspex roof with wood truss system, as long as you have a plan, measuring tape & saw you will be fine. Oh and plenty of savy.
