Roof valleys take the most water on your whole roof — that is why we line every one with ice and water shield.
On this North Charleston, SC roof replacement, Charleston Roofs and Windows is installing a self-sealing ice and water barrier down the valley before the shingles go on. In the Lowcountry driving rain, valleys channel water from two roof planes into one spot — this membrane seals around every nail and stops wind-driven rain from backing up underneath.
It is the detail you never see once the roof is finished, and the one that keeps a valley leak from ever starting.
