In most cases, below 40 degrees Fahrenheit is too cold to replace a roof. The cold affects the shingles, making it more difficult to adhere them to your roof. It also becomes dangerous for contractors to get up on your roof in the cold weather, as there can be ice and slush causing surfaces to become slippery.

A roof replacement can take anywhere from one to 14 days. For most homes, a full replacement that includes tearing off old materials takes about one to two days, though the average project can last up to 12 days. The exact timeline depends on several factors, including the roof's size and complexity, the type of roofing material, the crew size, and weather conditions. Certain materials take longer to install; for example, metal roofs can take seven to 14 days because the material is more difficult to work with than asphalt shingles, wood, or tile. A re-roofing project, where new shingles are installed over old ones, can take half the time or less. It's also important to factor in the time needed to obtain necessary permits. A professional roofing contractor will typically complete the job faster than a DIY approach.

The common formula for measuring a roof is length x width equals square footage. Professional roofers measure the length and width of your roof, including dormers, and determine its pitch and rafter sizes. If a roof surface is a triangle, they’ll divide that square footage by two, then add up the square footage of each surface to get the total for the roof.

Though cedar shakes often get confused with shingles, there are a few key differences between wood shakes and wood shingles. For one, cedar shingle prices are lower, although shingles are less durable than wood shakes. Cedar shakes are thicker than shingles (shingles range from about 3/8 to 1/2 inches thick, compared to 1/2 to 3/4 inches thick for shakes). Wood shakes are handmade, while shingles are usually machine-made. Also, wood shakes work better on steeper roofs than shingles do. While the cost of cedar shingles is more budget-friendly, there are many great reasons to choose shakes.
