Installed between the roof’s deck and asphalt shingles, the underlayment provides an additional layer of protection not just for your roof but also for your entire abode. 4U Roofing, one of the top roofing contractors in the local area, explains the many reasons why it is an important component of roofing systems.
Effective Water Repellent
The underlayment is installed flat on the roof deck or sheathing so water drains off the roof and doesn’t leak into your home. It is possible that wind-driven rain can get trapped underneath the shingles and with the waterproof material providing an extra layer of protection, your deck and your home’s interior are less likely to suffer the damaging effects of moisture damage.
Additional Weather Protection
The roof’s asphalt shingles are indeed the primary line of defense against the elements. However, roofers make sure the underlayment is installed first before the shingles so the roof can have a backup layer in the event a storm hits your area. If some shingles get blown off the roof, the underlayment protects the wood deck against rainwater until the missing shingles are replaced.
Sometimes, roofers may notice that the roof deck or sheathing doesn’t lay perfectly flat. So, during the roof replacement, they install a layer of the protective membrane to create a uniform surface upon which they install the asphalt shingles. By covering the top of the uneven wood, the pros prevent what is known as the “picture framing” effect, which is the appearance of a visible outline of deck panels as a result of irregularities in the roof deck’s thickness.
