Many homeowners believe that a modern home looks better with a flat roof than a sloped roof. A flat roof can provide several aesthetic benefits for modern homes. Among the pros and cons of a flat roof for a modern home design are the clean lines and straight edges that it delivers to improve curb appeal.

When it comes to choosing the best roof color for a blue exterior, you have plenty of options. For a classic neutral look, go with a light gray, dark gray, or black roof. Blend gray tones if you want a more eye-catching look for your roof, or go for a different splash of color with a green or even red. Take inspiration from your neighbors if you want your house to fit in on the block.

Building code allows 24-inch on-center spacing for roof trusses. However, you can install them on 12- or 16-inch centers to handle large loads or other exceptional circumstances. In cases such as covering a wide span or supporting alternative roofing materials, where a structural engineer needs to evaluate or create a design for your trusses, the plans will indicate the spacing. 

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.
