When it comes to maintaining, installing, or repairing your roof, a roof jack is one of the most essential tools and components involved.
Whether you’re a homeowner attempting DIY fixes or a professional roofer from a reputable company like 605 Roofing and Contracting, understanding what a roof jack is, how it works, and which type you need is critical for safety and success.
What is a Roof Jack?
A roof jack is a temporary or permanent roofing accessory used primarily for two purposes:
-
Ventilation – Allowing air, gas, or moisture to escape from inside a structure.
-
Safety/Support – Providing a secure bracket for staging planks during roofing work.
These versatile components serve both residential and commercial roofing needs. At 605 Roofing and Contracting, we always integrate high-quality roof jacks into our roofing systems to ensure safety, performance, and longevity.
Types of Roof Jacks and Their Applications
1. Vent Pipe Roof Jacks
These are designed to fit over plumbing vent pipes, ensuring water doesn’t leak into the roof while allowing gases to escape.
2. Adjustable Roof Jacks
Primarily used to support planks or walk boards during roof installation or repair. They are adjustable based on the roof’s pitch.
3. Roofing Jack Flashing
A type of flashing system designed to seal the penetration area of the roof where a vent or pipe goes through. It prevents leaks and structural damage.
4. Electric/Mechanical Roof Jacks
Used to vent hot air from kitchen hoods, dryers, or HVAC systems to prevent moisture and heat build-up.
Why Roof Jacks Are Critical in Roofing Projects
Roof jacks play an important role in:
-
Preventing roof leaks
-
Maintaining attic ventilation
-
Enhancing roof safety for workers
-
Prolonging the life of the roofing material
At 605 Roofing and Contracting, we use premium-grade roof jacks on every project to meet building code requirements and maximize the roof’s performance.
Key Features of a High-Quality Roof Jack
-
Durability: Made of galvanized steel, aluminum, or rubber to withstand the elements.
-
UV Resistance: Especially in vent jacks with rubber gaskets.
-
Slope Compatibility: Adjustable to various roof pitches.
-
Easy Installation: Designed for quick integration into roofing systems.
-
Weatherproof Seals: Prevents rain and snow from seeping in.
Common Roof Jack Sizes and How to Choose One
When selecting a roof jack, size matters. Common diameters include:
-
1.5 inches
-
2 inches
-
3 inches
-
4 inches
-
6 inches
The size must match the diameter of the pipe it covers or the pitch of the roof for proper fitment. Our specialists at 605 Roofing and Contracting assess the proper sizing on-site to ensure seamless compatibility.
How to Install a Roof Jack Step-by-Step
Step 1: Prep the Area
Remove any shingles around the vent pipe and clean the surface.
Step 2: Position the Roof Jack
Slide the base of the roof jack under the shingles above the pipe and over the pipe itself.
Step 3: Secure It
Nail it down with galvanized roofing nails and seal around it with roofing cement.
Step 4: Replace Shingles
Lay shingles over the top portion of the flashing for a tight fit.
Note: Always consult a licensed roofing company like 605 Roofing and Contracting for proper installation if you’re unsure.
