Correct and sufficient flashing is extremely important when when making a roof water tight. We use a step flashing system where every shingle against a wall or chimney will have protection. Many roofers today use a one piece system which has proven to be insufficient. Just like all of our flashing, we use a thick gauge, pre-finished black aluminum product which is shipped to us pre-cut and pre-bent.
Where
brick walls intersect roof lines, counterflashing is needed. After
step-flashing is installed, an independent cap or counterflashing is attached
to the brick wall. With step-flashing attached to the roof and counterflashing
attached to the brick, both systems remain intact during any house shifting.
The counterflashing is hemmed into the mortar joints to prohibit any water
from intruding.
Many roofers use a thin grade, un-finished aluminum product to cut costs.
Like our step flashing, our counterflashing is a thick grade, pre-finished
black aluminum product. These areas must have quality products and proper
installation to be effective.
With our system,
roof jacks are nailed under the tabs and the 2x4's are held in place
on hooks. (See photos below) When the roof is complete,
the roof jacks are removed leaving your roof with no
penetrations through the face of the shingles.
