Sheet Metal Work - Should It Look Like This?
The new one was better... but nice?Noramasen said:
A downright deplorable job. If one is completely without professional pride or knowledge, they would leave an execution like this. There are many points of critique, but the most important errors that absolutely shouldn't be present, and which must be pointed out to the company, are:
Furthermore, it's hard to tell what type of black flashing it is despite the description, but regardless of how exposed the situation is, it doesn't look good. Feel free to take a picture from a bit further away, and it may become clearer, allowing for alternative solution suggestions.
- The so-called plaster edge where the execution is completely wrong. A proper plaster edge should consist of a "shelf" that is overbent at about 110º (with fold) so that if the plaster later comes apart, the water will run from the chimney and not into it. And there should NOT be any joint there as the plaster does not adhere to it.
- Left a fold without a binding which can seriously injure someone. And this binding should occur under the plaster edge.
- All sides should meet at their corners, otherwise, there will be different heights on the sides when the plaster is applied.
- If applying plaster to the chimney, for heaven's sake, there should not be any visible screws of mounting type, but hidden attachments with clips.
- And the same goes for the seam type of cuts in corners. It should be of a curved type.
Kind regards/Masen
Noramasen; I've "heard" that if you put together 2 sheets, they should be folded 3 times. Do you know anything about that?

Joking aside! Now I think you can be satisfied. It looks good. And you've placed the ridge tape correctly.

Not many right!J Joakim88 said:Had a tinsmith here at home today. We're getting various things done on the roof and he started with the lower flashing on the chimney. The chimney will be plastered later so this should be a flashing with a "putskant".
Since he also started on the dormer, I assume he considers himself done with the lower flashing.
I admit I've never seen a lower flashing up close, but I must admit I was disappointed when I saw what was installed on our chimney when I came home. Is it supposed to look like this? (the picture with black metal is on the flashing above the dormer window)
Take a look at www.teknikhandboken.se
There is professional information about metal as well as detailed pictures of execution for respective building parts taken from AMA hus.

What do you think about the new fitting that I uploaded pictures of then?
Looks good, the upcoming trim/finishing edge will be all the more important. I assume they will fold the trim together with the end of the top fitting and then finish with a plaster edge.. Try to figure out how thick the plaster will be, as the edge on the flashing should be the same. See picture and arrowJ Joakim88 said:
There are many standards for chimney sweeping that our municipality has become very strict about since they changed inspectors:F fribygg said:
- The ladder must hang on step irons.
- Steps on the roof must go straight up to the chimney. No diagonal or horizontal part may occur.
- Step(s) on the chimney must be permanently mounted. It must have a ladder. You must be able to attach a harness/safety line at the very top.
- There must be a platform at the top where the chimney sweep can stand.
If you don't fix this on your old house, chimney sweeping will not be approved for professionals. A neighbor has instead taken a chimney sweep course, but I'm skeptical if it's enough as he still can't get the chimney installation itself approved.
I wouldn't be able to comply with this as I have a dormer that prevents the ladder from going straight up to the chimney.elpaco said:

It became so much with this that we hired a sheet metal workshop for this task. After much argument between municipality, company, and ladder manufacturer, it was finally approved. It became some kind of example for type approval and we got it for free (13’ with platform). It looks roughly like in the picture but a bit uglier. However, we placed the platform so that it is not visible from the street. The roof ladder hooks, however, we had to have on the front due to the above reason.
- The ladder must be hung on ladder hooks.
- Ladder on the roof must go straight up to the chimney. Skewing over the roof or any horizontal part is not allowed
- Ladder(s) on the chimney must be permanently mounted. It must have a leader. One should be able to attach a harness/safety line at the top.
- There must be a platform at the top where the chimney sweep can stand.
If you don't fix this on your old house, sweeping won't be approved for professional operators. A neighbor has instead taken a chimney sweeping course but I am skeptical if it is enough since he still doesn't get the chimney installation approved.
How do you solve this if the chimney sweep isn't allowed to move sideways on the roof?
Or do you need to build a platform with railings then?
As the builder, you are responsible for ensuring compliance with current roof safety regulations during extensive roof renovations. See bbr chapter 8 Check out https://www.taksakerhet.se/ They have good guidance on what "applies" for small houses.M mattoys said:

Sooting from below? Self-cleaning?M mattoys said:
I don't know the rules by heart, only what was emphatically conveyed to me. For example, I want a small narrow "gangway" horizontally on the backside. But it wasn't approved. So some contraption of the kind you mention is probably needed if the inspector is strict. UNLESS you can pull the rungs from the other side of the roof. That's how we've done it since there is a patio roof made of channel plastic on the backside.M mattoys said:
