In general, shingles and underlayment mainly protect a structure's roof deck. This roof sheathing consists of smooth plywood panels that are attached to the building's rafters. When properly installed by Bergen County roofing professionals, this plywood can remain protected for several decades. However, minor damages over the years can contribute to decking decline. Because of this, contractors often use tearoff projects to survey the decking's condition and evaluate if a new roof needs to be installed.
Typically, each contractor has a slightly different installation strategy for each project. For example, workers may remove shingles and underlayment in sections or strip the entire surface all at once. Contractors consider both strategies and compare them to local conditions. If weather patterns are volatile, sectional removal is the best option to protect the entire project from extensive moisture damage. With smaller areas exposed, contractors can easily tarp the sections in rainy situations.
Regardless of material removal strategies, contractors must inspect all roof decking surfaces. Because roof edges are the most vulnerable to moisture damage, roofers will normally inspect the roof's edge first and work their way toward the rooftop's midpoint. During the inspection, roofers will also look for damage from pests such as termites. Roof replacement projects are perfect times to replace and repair decking because contractors can see all flaws once the roofing material is removed.

As a secondary inspection measure, contractors will also pull rogue nails out of decking. Professionals pay careful attention to the wood and its interaction with removed nails because areas deemed as quality wood could actually be saturated with water. Nails that are very easy to remove could indicate wood saturation, which needs to be addressed quickly.
Ideally, contractors want to preserve roof decking with additional accessories during the tearoff process. Drip edge accessories, for instance, are metal pieces that line roof eaves. Contractors simply nail these items to new or inspected decking to reduce future moisture damage issues. Roofers can even suggest ice and water barriers for the roof deck before installing traditional felt. In the end, all properly installed accessories protect decking from weathering elements through the years.
As contractors install a new roof, homeowners should be actively observing all progress from a safe distance. The homeowner should make sure that contractors are not revealing the substrate and immediately covering it with new materials because the decking needs to be thoroughly inspected before any materials are added. If decking isn't supportive, all connected materials will quickly fail and allow moisture into the home.
