Moisture-Proof Your Attic & Cut Energy Costs With Legacy Metal Roofs Hi-Flow Ridge Vents.

Some Ridge Vents Actually REVERSE Airflow In Your Attic,
Causing Moisture, Mold & Sweltering Temperatures.

Our Special High-Flow Ridge Vents Keep Your Attic Dry
& Your Home A Comfortable Temperature Year-Round.

Ventilation is one of the most important components of residential roofing in the Savannah, Hilton Head Island, and Beaufort areas. Yet it’s also one of the most misunderstood elements of roofing—even by roofing companies themselves!

We’ll explain.

Some companies use passive ridge vents on their customers’ homes. The design of passive ridge vents doesn’t allow for negative suction, which is essential for moving air out of the vent. What these passive ridge vents do is actually allow air move back through the attic and push the moisture—which is trying to get out—into your insulation.

To prove this, we put our Hi-Flow Ridge Vent up against the #1 selling roof vent on the market. We piped air and steam into a sample roof and placed both ridge vents on it.

Here is an image of the competitor’s ridge vent…

Passive Ridge Vent

Looks fine, right? But watch what happens to the airflow when this ridge vent is installed…

Air flows through the soffits, not the ridge vent!

The design of the ridge vents actually blocks air and moisture from escaping through the vent. The air gets trapped until it finally pushes through your attic walls and soffits. But, of course, not before creating high temperatures and ripe conditions for mold.

Now here’s what happens immediately after we switch the competitor’s ridge vent with our own…

Our Hi-Flow Ridge Vent

When we install our Hi-Flow Ridge Vent, the airflow instantly starts to travel where it should: the actual ridge vent.

This is what a ridge vent is supposed to do!

The design of our Hi-Flow Ridge Vent creates negative pressure, which draws air from the attic and through the vent. The increased airflow created by the Hi-Flow Ridge Vent prevents moisture absorption in your attic insulation.

Why Proper Attic Ventilation Is So Important

The Department Of Energy states that a home’s energy efficiency is reduced by 2.5% for every 1% of moisture in the attic. Some homes have as much as 10% moisture in their attics, which means 25% worse energy efficiency (and bigger energy bills).

A Legacy Metal Roofs Hi-Flow Ridge Vent can cut moisture levels in your attic up to 10%, thereby increasing your insulation’s R-Value by 25%. You’ll experience lower energy bills, more comfortable temperatures in your home, and longer performance from your attic insulation.

Note: Certain styles of home may not allow for a Hi-Flow Ridge Vent. In these cases, we suggest the following options:

  • Eave Edge Vents: For homes that don’t have soffit venting
  • Peak Vents: For California Contemporary homes
  • Wall Vents: For shed roofs coming off a wall


If you have one of these styles of home, we can still help. Get in touch, and we can explore your options.
