As the elements, be they sun, rain, wind, or hail, pound on your roof, they damage its coating over time. As this happens, it may begin to leak, exposing other parts of the house, or building, to damage. Depending on its extent, such damage can be costly to repair. 

This potential cost is the reason why most contractors prefer preventing such damage, rather than doing repairs. The elastomeric roof coating sprayer is one of the most effective ways of ensuring damage prevention when it comes to your roof, and its efficiency has made it a popular option for Canadians. In fact, it belongs in the sector with the highest growth rate in the roof refurbishment market.

Based on its status among consumers, there are plenty of opportunities for the elastomeric roof coating sprayer to grow within its industry - however, you’ll also need the best airless paint sprayer for roof coatings. Read on to find reliable models, and what size spray tip for elastomeric sprayers to use. 

Why Use an Airless Paint Sprayer for Roof Coating?

When it comes to coating a roof, airless sprayers are the most efficient option. These devices use a hydraulic or air powered pump, which releases the coating at a high-pressure flow rate. Generally, the minimum pressure for roof sprayers is 3000 psi, and the flow rate is 3-4 gallons each minute. 

This high flow rate, along with the pressure value, help ensure uniform application. With most roof paints, spray tips of sizes 521, 523, and 525 are best.

Deciding to use an elastomeric roof coating sprayer is the easy part; the challenge comes with determining which model to use. Some of the best options available include:
