By utilizing compressed air, roofers can effectively remove dirt, moss, or algae buildup from the roof surface, improving its appearance and longevity.

What should you consider when buying an air compressor for roofing?

Tank capacity

When purchasing an air compressor for roofing, consider the tank capacity. A larger tank allows for more compressed air storage, reducing the frequency of refilling and ensuring a continuous supply of air for roofing tasks.

For roofing applications, a compressor with a tank capacity of around 6 to 10 gallons is typically sufficient. This size provides a good balance between portability and continuous airflow.

Build and durability

The build quality and durability of an air compressor are crucial factors to consider. Roofing can involve demanding conditions, so choose a compressor with sturdy construction that can withstand rough handling and potential job site hazards.

Horsepower

The horsepower rating of an air compressor indicates its power output.

For roofing applications, consider a compressor with adequate horsepower to operate pneumatic tools effectively, such as nail guns or air hammers, without experiencing performance issues.

Psi

Psi (pounds per square inch) is the unit used to measure air pressure. Roofing tasks often require a certain psi range to operate pneumatic tools optimally.

Ensure that the air compressor you choose can deliver the required psi for the roofing tasks you’ll be performing.

Consider the psi requirements of your pneumatic tools as well. Most roofing tools typically operate within a range of 70 to 120 psi.

CFM

CFM (cubic feet per minute) refers to the volume of air that an air compressor can deliver.

Check the CFM requirements of the pneumatic tools you’ll be using for roofing. Different tools have varying CFM needs. Ensure that the air compressor you choose can deliver the required CFM for those tools.

It’s generally recommended to select an air compressor with a slightly higher CFM rating than the highest CFM requirement of your tools to ensure optimal performance.

Size and weight

Consider the size and weight of the air compressor, as they can impact portability and ease of use.

Roofers often need to move equipment to different locations, so opting for a compact and lightweight compressor can make transportation and maneuvering more convenient.

Noise level

The noise level of an air compressor is worth considering, especially if you’ll be working in residential areas or noise-sensitive environments.

To reduce disruptions, look for models with lower decibel (dB) ratings, which typically indicate quieter operation.

Maintenance

Evaluate the maintenance requirements of the air compressor.

Roofing projects can be demanding, and a compressor that requires frequent maintenance or has complex upkeep procedures may not be practical.

Opt for a model that is known for reliability and ease of maintenance to keep downtime to a minimum.

What size air compressor do I need for roofing?

When it comes to choosing the right size air compressor for roofing, several factors should be taken into account.

For solo contractors, a 3-gallon compressor is often considered optimal, providing suitable airflow for their roofing tasks.

However, if you’re working with a two-person crew, it is advisable to opt for a larger air compressor in the range of six to ten gallons.

This ensures a reliable and consistent air supply for both individuals during the roofing process.

On the other hand, for more extensive or large-scale roofing projects where multiple crew members will be using pneumatic tools simultaneously, it is recommended to invest in a compressor with a larger tank capacity, such as eight or thirty gallons.

Just make sure these monsters have wheels on them because they are heavy.

This allows for efficient operation and meets the increased demand for compressed air when working with a crew of more than one person.

Selecting the appropriate compressor size also involves considering the CFM and psi requirements of the specific pneumatic tools being utilized, as well as the frequency and duration of your roofing projects.

Why is tank capacity important for air compressors for roofers?

The recommended tank capacity for air compressors used by roofers can vary depending on the specific requirements of the job.

However, a common recommendation is to opt for a tank capacity of around 6 to 10 gallons for roofing applications. This size provides a good balance between portability and the ability to maintain continuous airflow.

A 6- to 10-gallon tank capacity is typically sufficient for most roofing tasks, allowing the compressor to store an adequate amount of compressed air.

This ensures that there is a consistent supply of air to power pneumatic tools such as nail guns, staple guns, and air-powered saws.

Smaller tank capacities may result in more frequent refilling, causing interruptions in work.

Conversely, larger tank capacities, such as those exceeding 10 gallons, may provide extended periods of continuous airflow but can become more cumbersome and less portable.

What type of compressor is best for roofing?

For roofing applications, a portable and versatile compressor known as a pancake compressor is often considered the best choice.
