How to Prevent Roof Leaks from the Start

How to Prevent Residential Roof Leaks

North Port has never had a recorded snowfall. About the closest the area could come was the dusting of January 19, 1977. So why should south Florida homeowners worry about ice shield for their roofs? Because ice shield is also water shield, and the material is one of the key ingredients needed to prevent costly roof leak repair from the start.

Triple Protection

Fiberglass-asphalt shingles are the single most popular residential roofing material in America, but they do not prevent roof leaks alone. They are only one part of the triple protection you should insist on when having a new roof installed:

  1. Water and ice shield
  2. Flashing
  3. Shingles, metal or clay tiles

Rubberized, self-adhesive water shield is an extra layer of protection that seals around nail holes, covers the entire roof, and prevents water from moving upward by capillary action against gravity.


Strong metal flashing is a must at valleys and around chimneys. It is impervious to water, so you never have to worry about leaks between sheathing and chimney stone, for example.

Avoid costly roof leak repair later by asking your contractor what gauge flashing, and what material, will be used on your roof. You have several choices, but price is a major point:

Copper — very, very expensive, but beautiful to look at and it mellows to a lovely green
Galvanized steel — Sturdy, but eventually discolors and can stain your roof
Aluminum — Never stains, never streaks, and far more economical than copper
As for thickness, go to a big-box home improvement store. Feel the thickness of their aluminum valley flashing sold in rolls (it will probably be around 0.0092”, nine-thousandths of an inch). If your contractor offers something similar, choose another contractor. Real flashing for real homes installed by real roofers should be thick like cardboard, not like thin paper. Typical residential, aluminum flashing is 0.019”up to around 0.026, or at least twice as thick as the DIY junk.

Nailing Pattern

Your south Florida roof depends on the shingles’ ability to lie flat and let water roll down to gutters, so firm attachment is crucial. A six-nail pattern is best practice for shingles that may be subjected to high winds, as opposed to a four-nail pattern often used.
