If you like the look of wood, tile, or slate roofs but need something lighter, less expensive, or lower in maintenance, consider plastic roofing materials. Plastic roofs are made from different blends of polypropylene, along with other synthetic materials. They are a distinct subtype of composite roofing materials and tend to be lightweight, durable, and easy to install. They come in many styles, from individual shingles to large panels that can mimic the look of a tile roof.
All these variations create a range in the total costs. The national average cost to cover a roof in plastic roofing materials is $8,000 to $12,000, with most people paying around $10,000 for a 2,000 sq.ft. plastic composite shingle roof with a slate style. This project’s low cost is $6,000 for an installed 2,0000 sq.ft. plastic shingle roof made of tile-look panels. The high cost is $14,000 for an installed 2,000 sq.ft. plastic composite shingle roof in a wood shake style on a complex roof with a high pitch, dormers, and multiple protrusions.
Plastic roofs come in many styles and qualities. Plastic roofing panels tend to cost the least to purchase and install. Polymer slate 1 and cedar-look shingles 2 containing recycled materials and ones formulated for extra durability tend to cost the most. There is also a range of mid-cost materials in several colors and styles. Below are the average costs to shingle a 2,000 sq.ft. roof broken down by the quality levels.
Plastic Shingle Roof Costs
|Plastic Shingle Roof Cost (Material Only)||$5,000 - $5,500||$7,000 - $10,000||$10,000 - $13,500|
|Plastic Shingle Roof Installation Cost (Labor Only)||$1,000 - $1,500||$1,000 - $2,000||$2,000 - $2,500|
|Total Costs||$6,000 - $7,000||$8,000 - $12,000||$12,000 - $16,000|
|Plastic Shingle Roof Cost per Sq.Ft.||$3.00 - $3.50||$4.00 - $6.00||$6.00 - $8.00|
Plastic roof shingles are generally lightweight, low-maintenance, and highly durable. The individual shingles can look very similar to slate or cedar shingles while being flame-retardant, lightweight, and durable. They hold up well to high winds, hail, and inclement weather, and because they are plastic, they also do well in wet areas. Most have a 50-year warranty, although the best-quality shingles may have limited lifetime warranties. Lower-quality plastic roofing materials tend to be larger sheets, so they install very quickly, but they may not look as nice as individual shingles.
While many higher-end materials can and do contain recycled material, the materials are difficult to recycle at the end of their lifespan. So, these cannot be considered sustainable or eco-friendly materials.
The average lifespan of plastic roofing shingles is 50 years, but some have limited lifetime warranties, meaning they may last even longer.
The average cost of a 2,000 sq.ft. plastic roof is $8,000 to $12,000, with $10,000 being the most common cost.
Yes, plastic roofing materials are highly durable and can be walked on without damaging the roof.
