When it comes to the cost of replacing a roof's underlayment, there are a few fixed costs that are easy to identify. For most homeowners, cost is the primary concern when it comes to replacing their roof. The cost of installing a new roof is determined by the materials used, labor, and any additional structures that need to be added. In addition, other factors such as tree debris or the shape and style of the roof can also affect the cost of the underlayment.
Generally speaking, the underlayment doesn't have a huge impact on the overall price of a new roof. While some areas may allow for asphalt to be installed directly on the roof without an underlayment, most materials require it and building codes often stipulate its use. All roofs can benefit from having an underlayment installed. The underlayment often wears out faster than more durable roofing materials such as shingles, so it may be necessary to replace it without replacing the entire roof.
Most green roofs use a waterproof membrane covered with a plastic sheet instead of a true underlayment. The ice and water shield or ice and water protector is a specific type of underlayment that is installed on the edge of the roof. A roof inspection can help determine if it's time to replace the underlayment or if the entire roof needs to be repaired or replaced. Roof inspections are beneficial for several reasons, even before replacing the roof or underlayment.
The underlayment of a shingle roof should be replaced every 20-30 years in order to prevent leaks and keep the roof in good condition. When replacing the entire roof and installing new roofing material, the cost of installing the underlayment is usually included in the total cost. This includes removing the existing roofing material, replacing the underlayment, and reinstalling the new roofing material. Asphalt felt underlayment is heavier than synthetic underlayment and therefore has less material per roll.
