There are five primary types of paint rollers to choose from: manual rollers, pad rollers, texture rollers and mini hot dog rollers. Each type has advantages and disadvantages and each is suited to specific kinds of painting projects. Just as with the cost of paint, the cost of a roller impacts the final result of the project. Some painters use a roller once and throw it away. Others invest in more expensive rollers that can be washed and reused many times. Avoid the temptation to cut costs on your project by buying the cheapest roller on the shelf
