Over 95% of roofers use highly pressured staple guns for speed. The biggest problem with this method is that thin wire staples applied under high pressure can easily press through the shingle (especially on a hot summer day when shingles are soft.) that means shingles can come loose and detach from the roof, leading to roof leaks.
Integrity Home Pros Standards
We use only coil nail guns with round head nails. The large round nail head holds the shingle more secure than a staple. Plus, fastening a nail into stronger laminated plywood sheeting will last longer and won't pull through the shingle. We install using a 6-nail pattern - 50% more than industry standards - which gives a higher wind-performance rating.
