Get matched with top roofers in Minneota, MN

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.

You can think of a flat roof as a green roof, as it does offer some environmentally-friendly advantages. When considering an eco-friendly flat roof, some of the green roof pros and cons include that you could place a garden with plants on the flat roof. Manufacturers may use recycled materials in the construction of the flat roof for an eco-friendly design.

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.

Verify that your roof is licensed and insured by visiting your state's contractor's licensing association. Most states have a database to double-check your contractor's name and address against the information provided. The contractor should also display both their license and insurance on their website with links to the related agencies.
