Underlayment is used between existing shingles and a new metal roof to prevent friction and wear from the shingle granules on the underside of the metal. The underlayment also helps prevent water intrusion and allows expansion and contraction without wearing away at the roofing material.

Fall is widely considered the best time of year to replace a roof. The moderate temperatures are ideal for roofing crews to work and for new shingles to seal properly. Additionally, autumn weather is often drier, reducing the risk of weather-related delays compared to the rainier spring season.

While spring is also a viable option, the higher chance of rainfall can slow down the project. The main drawback to a fall installation is that it's the peak season for roofers, which can lead to higher prices and scheduling challenges.

To potentially save money, you could consider scheduling your roof replacement during the summer or winter off-seasons. However, both seasons have significant disadvantages. Extreme summer heat can make shingles too soft to handle, while winter's cold, snow, and ice can create dangerous working conditions and prevent shingles from sealing correctly, as they typically require temperatures above 40-45°F.

Roof vents are an essential part of a roof, as they promote energy efficiency by keeping warm, humid air at bay. The roofing material, especially asphalt shingles, will not last as long as it should (about half of its manufacture life) if the attic is not ventilated. Also, going without ventilation means having a warm attic that demands more from your air conditioning system (and your wallet, once the bills come). Ridge vents and roof vents also prevent a host of other icky moisture-related problems like rot, mold, and mildew.

If you’re choosing between a roof overlay and a tear-off, opt for a tear-off and full roof replacement instead of a roof overlay if possible. The cost savings from an overlay can easily be eclipsed by repair costs, the effects of structural damage from the additional weight, and needing to replace your roof sooner than expected. A full replacement will last longer and is less likely to need damage repaired over time.
