Essential Power Equipment for Commercial Roofing

Gas-Powered Equipment for Big Roofing Jobs

& the Engines that Keep them Running

Professional roofing companies rely on specialized power equipment to complete projects efficiently, safely, and with professional results. From tearing off old shingles to installing new roofing systems, having the right tools can significantly impact productivity, job quality, and overall profitability. In this guide, we’ll break down the most important types of power equipment used by roofing professionals and how each contributes to successful roofing operations. 

Demolition Equipment

Roof Cutters

Mainly used in commercial roofing, a roof cutter is a heavy-duty walk-behind machine equipped with a reliable power source and a rotating blade that efficiently cuts through multiple layers of roofing material. These specialized cutters are used to prepare large roof areas for demolition – the operator will use this piece of equipment to cut the roof into manageable sections for the next phase of tear-off.

Roof cutters come in a variety of sizes from mini-cutters to larger machines that feature water pumps and vacuums to minimize dust and debris. Similarly, select Honda engines feature a heavy duty Cyclone air cleaner specifically designed for dusty environments like roofing demo jobsites, making them ideal sources of power for roof cutting machines. Honda’s Cyclone air cleaner spins incoming air to fling off larger debris particles before passing through the paper filter, ultimately protecting the engine’s internal components for a longer life. Check out our selection of Honda engines that feature a Cyclone air cleaner.

Small roof cutters or mini-cutters commonly utilize Honda GX160 engines as a reliable source of power, while popular brands of large roof cutting machines are equipped with  Honda GX390 engines or Kohler CH740 engines.

Tear-Off Machines

Walk-behind roof tear-off machines, also sometimes referred to as roof peelers, replace manual scraping to efficiently strip and remove old roofing materials like shingles, built-up roofing layers and insulation down to the bare structural roof deck. Tear-off machines oftentimes utilize a gas-powered engine and reciprocating or vibrating action to drive a hardened steel blade between the roof deck and old materials. The wide, vibrating blade slides under asphalt, shingles and other layers and easily pops up roofing nails to expose the structural deck below. 

Honda GX390 horizontal engines and GXV390 vertical engines are commonly trusted to power walk-behind tear-off machines. Contact us to verify which engine is right for your gas-powered roof peeler!

Roof Planers / Roof Spudders

Usually powered by a gas engine, roof spudding machines efficiently and accurately strip away embedded gravel, slag and old asphalt down to the roofing membrane. A roof spudder is an essential piece of equipment for the removal built-up roofs (BURs) – these are flat or low-sloping roof systems made up of alternating layers of ply sheets and waterproof bitumen and topped off with a layer of gravel or stone.

Roof spudders, also commonly called roof planers, feature a rotating flywheel and heavy-duty, carbide-tipped teeth that rapidly strike the gravel and asphalt, removing the old removing materials without causing structural damage. Planing machines ensure an even, level surface for the proper installation of new roof systems. 

Popular gas-powered roof planer models are commonly powered by select Honda GX270 horizontal engines and GXV390 engines. If you are looking to repower your roof spudder with a reliable new engine, send us a message and one of our experts will find the right replacement for you.

Deck Preparation

Powered Roofing Buggies

Power buggies are versatile pieces of equipment made to transport heavy materials. Power buggies typically feature a gas-powered engine, heavy-duty wheels and a large dump tray for either hauling old materials away or transporting new materials on-site. Power buggies come in both walk-behind and ride-on variations and some models feature hydraulic lifts for easy dumping of extra-heavy materials. Think of them as wheel barrows on steroids – they come in handy across many lines of work including landscaping, concrete construction, home remodeling and more. 

While power buggies are not unique to the roofing industry, GATOR designed its own Deck Pony with roofing professionals in mind. Thanks to its heavy-duty, flat-free tires that evenly distribute the machine’s weight, the Deck Pony can be used on commercial flat roofing jobs without damaging the work surface. This specialized stand-on, chariot-style buggy can reach a speed of up to 6 MPH and is designed without belts, chains and sprockets to minimize mechanical issues and greatly reduce any downtime. The Deck Pony’s high-capacity dump tray can easily handle heavy loads of PVC rolls, insulation and other roofing materials and, if that’s not enough, a simple center-pin system allows for additional attachments like forklifts and trailers.

Roof Sweepers

The demolition of old built-up roofs can leave quite the mess; that’s where roof sweepers come into play. Roof sweepers are heavy-duty, gas-powered pieces of equipment made to efficiently remove dirt and debris from roof surfaces, ensuring a clean area for proper adhesion before laying down liquid coatings, membranes and new roofing systems.

Roofing sweepers typically feature large rotating steel brushes that cover wide swaths to quickly clear roofing surfaces of loose gravel, shingle fragments, insulation pieces and other demolition waste. The steel bristles also scrub and scarify the work surface, creating an ideal bonding surface for adhesives and other liquid coatings.

Powered sweepers used for roofing applications are commonly powered by (but not limited to) Honda GX160 engines and Honda GX270 engines. If you are needing to repower your roof sweeper, contact our team to find the right replacement engine to get back to work as soon as possible!

Blowers

Another way to make quick work of debris removal on roofs is by utilizing blower/vacs. Handheld and backpack blowers can easily sweep away lightweight dust, dirt and leaves, while walk-behind wheeled blowers offer a boost in power that proves necessary in clearing heavier pieces of roofing debris on post-demolition surfaces.

Application

Hot Asphalt Kettles

In built-up roofing (BUR), bitumen, more commonly called tar or asphalt, is melted down to a liquid state and spread on flat or low-sloping roof surfaces to provide a protective and strong waterproof seal. Hot asphalt kettles are large, sometimes trailer-mounted, vats that can hold hundreds of gallons of bitumen, making them ideal for commercial roofing jobs. Powerful liquid propane gas systems are responsible for rapidly melting the asphalt, while an engine-powered pump provides reliable, clog-free asphalt delivery from the vat to the working surface.

Gear reduction engines such as the Honda GX270 HA2 are ideal for large roofing tar kettles because they convert high motor speed into high torque at a slower, controlled rate. This makes gear reduction engines the best option for countering the heavy resistance of thick, sticky, high-viscosity tar through the pump without damaging your equipment.

Adhesive Sprayers

Industrial sprayer set-ups cut adhesive application time in half by spraying bonding liquids and low-rise foam evenly and quickly across large flat surfaces. Mobile roof sprayer carts consist of a generator (commonly powered by an engine), adhesive drums or canisters, hoses and spray wands. Common applications where adhesive spraying carts come in handy include membrane bonding, foam insulation attachment and flashing.

Power Sources

Generators

Generators are a versatile power source for commercial roofing crews, providing electricity for everything from jobsite lighting and battery chargers to saws, drills, pumps, sprayers and other equipment. They are particularly valuable during new construction, renovations, and projects where permanent electrical service is not yet available or where additional power is needed to support a busy jobsite. With the ability to deliver substantial electrical power without relying on a building’s utility connection, generators give contractors greater flexibility in how and where work gets done. Their combination of high output, mobility, and dependable operation makes gas-powered generators a practical solution for powering the equipment and temporary electrical needs of commercial roofing projects.
