 Installed
Over the Top ~ Valley Flashing is installed on top of the felt
paper but does not guarantee there will never be a leak. The way the
shingles are laid over the flashing is most important. |
|
 Closed Line Valley
~ Systematic Roofing completes their valley installation by continuing the
shingles on the major roof 3' up on the minor roof. Then, overlapping the
minor roof shingles, popping a chalk line down the center of the valley
and trimming the top layer. |
