Asheville Roofers Inspects an older Dimensional Shingle Roof

This area is missing a shingle due to delamination. Delamination is the process in which one shingle comes apart and breaks into 2 pieces. The top section and the bottom section

More areas of delamination this is due to the high nailed nails.
Here are a few pictures of the nails being too high

Rusting nails are also signs of water under the shingles, and this is due to the missing shingle just above this area. 

The small holes in the ridge cap are due to the crack in the ridge cap shingles.

Lots of nail pops on hips and through the roof.

Here is another area with missing/delaminated shingles. They used metal or flashing to temporarily fix this issue.

This pipe boot is not installed correctly and they didn’t even mail it down leaving the bottom popping up about 2 inches.

Same thing as the other side. Not nailed down and it needs a rubber cover over it as well

More delamination 

This section of the roof took the most time and was very very difficult due to the steepness of the roof, how brittle the shingles were and the fact that the granules would wipe right off the shingles from just the smallest amount of pressure. We originally only had to replace one or two shingles in this spot but the shingles kept breaking on us so we just kept replacing them. When we finished this area it was a major success so we were very happy with the outcome!

Also very tough to repair due to the brittleness of the shingles. We only put a few nails in the far right side away from the valley and glued the left side of the shingles that were closest to the valley to keep from putting holes right there.  We did however find that the roof had nails way too close to the valley some nails were almost in the valley. This will cause future leaks. So we did caulk under the shingles where we found nails.

I was originally going to just put caulk over the top of this but decided to put the tip of the caulk gun in the main hole and pumped it inside the hole until it started coming out. This basically filled up the entire hole and crack. Then went over the top with more sealant. Plus we sealed the top of the exposed nails as well

As you can see in the pictures there were a lot of nail pops in this section of roof. The nails were hammered back in place and then we sealed up the holes.

This was one of the simple fixes we just slid a piece of flashing underneath both shingles and used sealant to seal up the crack

While replacing the shingle we noticed that the transition metal was warping and buckling so we decided to cut the metal vertically so it could overlap itself and lay down flat. we then sealed that cut and installed a new shingle over the metal.

On this side we replaced a delaminating shing just like we did on the opposite side of the dormer and except the transition metal was fine on this side and didn’t need to be cut.

We sealed underneath the right and left side of the pipe boot, nailed it down, sealed over top of the nail heads and slipped a new rubber sleeve on top

Like the title says just small random nail pops, cracked shingles, and other miscellaneous stuff

We sealed under the pipe boot on both the left and right side, nailed it down, sealed the heads of the nails, and put a new rubber sleeve over top.
