The bottom of this valley was so rotted that by the time all the bad wood was removed there wasn’t much left. Two trusses were repaired along with some decking, fascia and soffit. The entire repair area was then covered with 30 lb. felt and tin-capped to Code. Next, 3” x 3” galvanized drip-edge flashings were nailed every 4 inches at the perimeter. Prior to the valley metal install Tarco PS200 self-adhering tile underlayment was installed from the bottom eave up through the valley area.
Then 18” galv. valley metal was set in roof cement at the nail line and nailed down. Then all metal flashings are coated with fast-drying asphalt primer for good adhesion of the underlayment which was then installed over the entire area, leaving a 4” cut down the middle of the valley for the tile install.
It’s time to put the tile back – right? Wrong!! It’s time for a tin-cap and in-progress inspection. Welcome to Miami-Dade County! Pictures of the tin caps are OK but the inspectors want to see it before the tile is put back. This makes it impossible to do a job like this in one day and drives up prices.
Having passed inspection we returned and put back the tile. These were 10 year old Altusa Clay roof tile – discontinued, hard to find and expensive. New Altusas cost about $1.25 each but Altusa doesn’t maintain a consistent profile from year to year, so they won’t fit. You’ve got to take a sample from the job and shop the tile salvage yards and when you find them, they are $4.00 each! So, we install the tile with Tile Bond adhesive, mortar the valley and trim and we’re done – right? No!! Time for final inspection . . .
