Roof Ventilation

Flat Roof:
If your flat roof has moisture or blistering, we can eliminate that problem by adding new roof ventilation. 
If your flat roof has insulation and its soft when your walking on the roof, you might need some roof ventilation added to your roof. 

Sloped Roof:
Most sloped roofs have an electrical fan that is plugged in your attic and you dont even realize its running and using electricity.
A more economical way of Roof Ventilation is adding a couple of turbines to your roof. The roof turbines spin and cause a draft ventilation at an upwards motion to remove most of the heat that is contained in your roof attic space. This way your roof can breath and you will notice your garage is cooler but most of all it will cut down on your air conditioner running harder and save on the electricity.


Why Vent Through the Roof?

Make your Dryer last longer & work less and cut down on the electric bill!!!

For dryer efficiency and safety, the shortest and straightest ducting route is always best. Every turn increases friction loss (unless you use non-restrictive elbows). Air velocity reduction from friction loss promotes lint build up and makes the dryer work harder to completely dry each load. Length of run also reduces efficiency. The longer the run, the more friction loss is created which is why building code restricts total run length. Often, going straight up through the roof is the shortest route.

Some contractors, builder and vent cleaning technicians have been reluctant the vent the dryers exhaust run through the roof. For some, the more “popular” option is to vent through the side of the house. This document will address any concerns and confirm that venting through the roof is allowable. In some cases, roof top venting is the most efficient and safest solution.

While elbows and length-of-run are important factors for efficiency and safety, the exhaust termination is often the biggest restriction point. The Dryer Jack, in fact, was born of extensive testing of the Dryer box and Dryer-ell and how they improve airflow. In real-world tests, inefficient roof terminations would often all but negate the improved efficiency of eliminating restrictive elbows. While it sometimes made sense to vent through the roof, every roof vent that had previously been used was inefficient (often to a dangerous degree). In order to take advantage of the shortest route, a better termination was required.

Dryer Jacks are the first roof vents designed to meet the more stringent venting requirements of dryer exhaust systems. Unlike the vents shown above-left, the Dryer Jack affects airflow by less than .01 water column inches of pressure.

Considering that back pressure higher than .6 WCI is generally recognized as inefficient, you can see that venting through the roof with non-dryer specific vents is immediately problematic. The less back pressure is created by the roof vent, the more efficiently the system performs.

The new Dryer Jack is the most efficient. The position and curvature of the damper, combined with hood size and collar placement, optimize airflow to such a degree that laboratory tests confirm nearly zero reduction in airflow. Terminating the shorter duct run with a Dryer Jack helps venting through the roof deliver on the promise this shorter route offers.

At less than 5 1/2" above the roof plane, it is also low-profile for minimal visibility. For medium snowfall zones and / or higher profile roof tiles, select the larger model 486 which is as efficient but taller.

Airflow Efficiency: Zero airflow restriction is achieved thanks to the combination of a unique curved damper, larger vent opening, and collar placement. Allowing the dryer to perform at peak efficiency helps reduce lint buildup (and the resulting fire hazard), and it keeps dryer times low which reduces wear and tear and saves energy.

Maintenance Access: Dryer exhaust systems need to be cleaned—from beginning to end—regularly. Dryer Jacks include special design features for ready access that is easy on cleaning tools. The ability to clean vents from both ends can be a major advantage for longer runs, and it is helpful for a thorough cleaning.

Elements Protection: To protect against dangerous lint build up at the termination, all building code disallows screens that would, otherwise, protect against pest intrusion. Special attention to the shape, position and how the damper rests inside the hood when closed, delivers intrusion prevention without the use of screens.

The closure also protects against weather. Water tight collars extend above the nailing flange to prevent water intrusion in the exhaust duct.

Quality Construction: Tough as nails construction, built right here in the US, ensures a very long duty life. The tightly engineered housing, flange, damper and collar are all constructed of 28 gauge galvanized steel.

Dryer Jack hood features balance aesthetic objectives with application requirements. Rounded flange corners simplify handling, and built-in nail holes help speed installation.

Performance Matters: Typical roof terminations have been proven to restrict airflow to a dangerous level when it comes to venting dryers. Poorly designed roof vents are more than just an eye sore; they are rarely duct cleaning accessible or pest resistant.

Dryer Jacks deliver advanced performance for improved safety, efficiency and duty life.

Dry Jacks are manufactured right here in the USA and come in Black & Brown Powder Coated or Mill Finish.
