Homeowners may look up at their roof to see a perfectly flush, shingled surface, but there are more layers to this protective component than just shingles. Underlayment or roofing felt is the hidden layer beneath the shingles. Although it's not usually seen unless a home is being repaired by Highland Park roofing professionals, underlayment is one of the most important roof elements that must be understood to keep a home leak free for many years.

Underlayment is a specialized coating because of its asphalt construction. Construction crews used to refer to the material as tar paper because of its asphalt component. Asphalt is a strong material that fights off leaks and saturation. If any moisture does find its way beneath the shingles, it can trickle down the underlayment to the roof's gutter system. It's essentially another barrier to deter water damage across the roof's surface.

Shingles are layered to keep water from seeping under them. This same concept applies to underlayment when it is installed. Contractors roll the material out, allowing it to overlap another section by a few inches. It's better to have too much overlap than not enough because this overlapping prevents any water from seeping into seams. If any cracks arise, some of them might be covered slightly by the overlap until contractors can fix the issue permanently.

Underlayment failure can arise if shingles are missing from the roof. After a particularly bad storm, loose shingles may fall to the ground, leaving the underlayment exposed to sunlight, wind and other weathering elements. If roofers cannot replace the missing shingles in a timely manner, the underlayment can actually break down under stressful conditions. Even the best layering cannot stop ultraviolet radiation and pounding rain from damaging underlayment to the point of cracking.

When a new roof is being installed, the underlayment process is the foundation. New materials should be rolled and layered together. Workers often wear specialized shoes to prevent damage to the materials as they're being added. Questionable roofers might tear at underlayment if they walk across the surface with inappropriate shoes.

Contractors can add different underlayment types to a roof as they shore up the structure against potential leaks. If an area is prone to icy conditions, an ice and snow shield is preferable during a new roof installation. Homeowners must work closely with contractors to create a roof design well suited to the area's weather patterns and home's overall beauty.
