4 Big Reasons NOT to Skip a Secondary Water Barrier

In cold parts of the country, secondary water barrier material is sold as “ice and water shield,” because temperatures in those areas drop enough for ice to form on roofs. Tampa almost never has to struggle with freezing temperatures, according to The Tampa Bay Times, so why would area homeowners need a product to protect against ice? For four reasons, the secondary water barrier Florida homeowners request on their homes can also help your home.

Prevent Leaks

Secondary water barrier, unlike felt paper, seals completely around nail penetrations. This self-adhesive underlayment protection rolls out flat and provides just enough thickness and elasticity to re-form around each nail. Water can easily leak through the nail holes piercing felt paper, but cannot get through the secondary water barrier.

Protect Valleys, Rake Edges and Eaves

The most leak-prone spots on your roof are the valleys, rake edges and eaves of your roof. Water can drive up under shingles, pool in valleys, and slip sideways along ridges and hips. Secondary water barrier on a Florida home prolongs your roof’s structural integrity.

Hurricane Winds

The alternative to secondary water barrier Florida homeowners can choose — felt paper — is not self-adhesive. It comes up when the shingles atop it come up, as in hurricane-force wind uplift.

The adhesive on secondary water barrier on Florida roofs is so strong, it does not lift up with high winds. In fact, when roofers need to replace a shingle roof equipped with secondary water barrier, they sometimes have to replace the plywood sheathing, since the barrier peels up the wood ply during removal. The material is that tough.

Last Defense

Either at installation or after a major storm, entire sections of your roof may be exposed to the elements. If the sheathing has a smooth, unbroken layer of water-repellent secondary water barrier on it, even without tiles, slate or shingles, your home is protected. It is a last defense against water damage.

Roofs with secondary water barrier may require venting so moisture does not become trapped in the sheathing, and care must be taken when removing the backing paper and smoothing the product down.
