The principal, common, and auxiliary rafters are the most frequently used types of rafters. Principal rafters are large and typically appear toward the edges of the roof. Common rafters are smaller than principal rafters. Some people may use a mix of common and principal rafters. The auxiliary rafter is not common, but it provides extra reinforcement for a principal rafter on a large building.

The cost to install a drip edge on an existing roof runs about $1 to $3 per linear foot, which comes out to between $150 and $1,000, with an average cost of $575. These are just averages; the total project price can vary depending on the type of drip edge chosen and whether you hire a professional for the installation. Factors like roof size, complexity, and labor rates also play a role in determining the final cost.

The type of roof and roofing materials that are best for your mobile home depends primarily on its shape and slope. Rubber materials, such as EPDM and TPO, are best for flat, low-sloped, or bowed mobile home roofs. Asphalt shingles or metal roofing are best for mobile homes with sloped rooflines.

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.
