xdrive, good evening.
images 1 and 2 from the top are failed paint finish, the applied white exterior paint has over a long time begun to break down and is now failing. From what can be seen there are no "Structural" cracks visible, that does not mean that there are cracks masked by the failing paint?
In image 3 [the bottom one] ? that is a different thing?
It appears that the [porch???] is a relatively recent addition [or replacement?]
The vertical crack between the main properties elevation and the porch is of some concern, it appears that this area my be moving or rotating away from the main elevation??
If indeed the porch has been replaced??? do you know if the porch installer introduced any corner metal posts to carry the load of the roof rather than letting the load of the roof impinge on the new porch structure itself which will not be able to carry any sort of a "Load" from the roof above?
As for repair.
1/. Paint finishes, scrape. power wash, soda blast to remove existing paint.
Note, the window in the image may??? have some wood rot??? the Putty line could do with some attention? [clear the grass out of the gutter???]
The Flashing between the wall elevation and the roof tiles looks a wee bit iffy??
2/. Porch? where to start?
Get the installed back? [is that an option]
Cannot quite see what is going on with the horizontal [beam??] directly above the new porch.is it an RSJ [Steel beam?]
The front fascia appears to have an attack of wood rot, and should have been replaced with the porch.
Some good and bad news??
Hope it assists.
Ken.
