You can see the old hip roof of the small back porch roof before this addition/remodel. No roof overhang. The gutter should be under a drip, independant of the rubber roof. |
This is the obvious ponding problem. Look how flat the 3-tab roof shingles look on the eave of the main house (in front of the dormer). (click the photo for more detail). This is the real leak if you ask me, water does not go through rubber |
Here is the old porch hip roof from another angle. This hip should be removed so we have a true flat roof with a deliberate pitch. (The a/c units are just sitting there, completely disconnected) |
Broken insulation board tells of irregular support from the sheathing below. 1x10" sheathing boards flex between rafters. Since this roof is flat and walkable 3/4" T&G would prevent this from ever happening. |
Looking parrallel to the back of the main house apart. Nice inside corner, lol. Look at that turn bar, egads! |
The following shots are the views from the roof deck facing NE and panning east back to the main house and then continuing around to the west which is the driveway side. What a deck this could be! |
If that old hip roof was gone, the head height would improve for a door to replace one of the windows in this back dormer, giving better access to the roof top. More means of egress is always good. |
Lots of ponding. The result of irregular roof framing. Sistering existing rafters with new 2x6's to two stretched mason lines that are set to give to 2" pitch over 20' will give a true flat roof with no ponding and good drainage. |
