The time it takes to install a new roof in Wilmington NC depends on the size of the home or business building. Smaller homes that measure less than 1,200 square feet can usually be completed in one day, while larger homes of at least 4,000 square feet may take a couple of days. The complexity of the roof is also a factor; a simple and direct roof will take less time than one with smaller roofs, dormers, etc. When it comes to permissions, there is a general guidance table (PDF) that provides information on what is required for each project.
This may involve the installation of various roofing materials, such as constructed, modified (SBS) or single-layer roofs on conical insulation systems for roofs with low slopes, as well as asphalt shingle systems or metal panels on steep slopes. These materials can have different lifespans; constructed roofs can last up to 25 years, while metal roofs can last more than 40 years if properly installed and maintained. Slate, tile, and green roofs may need additional support due to their weight. Tile roofs can save thousands of dollars on energy bills compared to other types of roofs. Metal roofs take longer to install than asphalt shingles.
Flat roofs are most often used in commercial buildings, warehouses, and large retail outlets where a large roof extension is required. If the roof has significant damage from a roof leak, water damage, mold growth, or natural wear and tear from age, then it's time to replace the entire roof. This will require tearing off the old roof and installing the new one. When hiring a commercial roofing company for repair or replacement, make sure they are experienced and knowledgeable. The average commercial roofing system can last between 10 and 60 years depending on the type of material used, the quality of installation, and the level of maintenance.
TPO roofs are a type of single-layer roof that has characteristics such as high resistance to UV radiation, durability against chemical agents, and resistance to fire, mold and mildew. The size of the roof is the most important factor in determining how long it will take to install a new roof. Metal roofs are arguably the most durable option and can take anywhere from a few weeks to a month for replacement and installation. This depends on several factors such as the type of new roofing material you want to install, existing conditions and penetrations, the size and surface of the roof, the delivery time of the material, and the number of roofing technicians working on the project. It is important to note that synthetic rubber used for residential and commercial properties has been used effectively in the roofing industry for more than 50 years.
