Flat roofing in Greenville, SC can vary significantly in cost. Initial estimates frequently range from $6,800 to $12,798 for a typical replacement, but this figure can fluctuate considerably. Several factors, including materials, roof size, and the condition of your existing roof, all contribute to the final price. Asphalt roll roofing represents the most economical option, often falling within the $117.39 - $194.15 per 100 sq ft range. More premium materials like EPDM rubber, GRP fibreglass, or even metal roofing, will increase the price substantially – potentially adding several thousand dollars to the overall cost.
To illustrate, let's consider a 2,119 sq ft roof, a common size in Greenville based on average data. An asphalt roll roof replacement could cost approximately $24,500 - $39,500. An EPDM rubber roof would likely fall between $31,700 and $47,500, while a metal roof could range from $38,800 to $62,300. These figures give you a baseline for evaluating materials. It's crucial to get multiple quotes from local roofing contractors to ensure you're receiving accurate and competitive pricing. The cost of tear-off should also be considered, potentially adding an extra $500 - $1500 depending on debris removal needs.
