PVC Roof
PVC Roof has been a roofing material in the US for over thirty years. This type of material is a sheathing or membrane material which should only be used on flat or low sloped roofs. The material has a good life span and comes in a variety of color options to enhance the property.
PVC Roof to The Basics
A PVC roof is installed using heat welding. A membrane or sheet of PVC is used and covers an entire roof with ease. The advantage is that there are no joints or seams, reducing the risk of leaks. Each sheet is made of glass fibers and polyester which are woven together. When it comes to installation, the process is an easy one. Each strip is placed and then they are heat welded to each other, this forms one membrane which covers the entire roof. The strips come in 10 and 12 inch strips, which are durable and puncture resistant.
PVC Roof Costs
Low to Middle Range - $3 to $4.50 per square foot. With installation and materials, a homeowner can expect to pay in the region of $300 - $450 per square.
Middle to High End Range - $4.50 to $6 per square foot. Once installation and materials are factored into consideration, the cost can be in the region of $450 and $600 per square.
The Benefits of A PVC Roof
Reflective
A PVC roof is known for its heat reflection. This roofing material can offer up to eighty percent solar reflectivity, it effectively reflects the UV rays into the environment. This means that PVC roofs tend to help keep the interior of the property cooler during the summer, reducing the cost of air conditioning.
Reduced Risk of Leaks
PVC roof membranes use a heat welding process to attach the membranes or sheets together, covering an entire roof. Without joints and seams the risk of leaks is dramatically reduced.
Any Size Roof
PVC roofs are normally put together on-site, this means that they can be applied to any size roof with ease. Because the installation process is an easy one, this can be a cost effective roofing solution for larger properties.
Repair
Repairing a PVC roof is a quick and easy process. Any damaged areas can be quickly removed by a contractor and the new piece of PVC is just welded into place.
Disadvantages
Shrinking
The main downside to a PVC roof is that the material does tend to shrink over the years. This can result in repairs being required as the shrinking puts unnecessary strain on the joints and seams.
Cold Climates
The National Roofing Contractors Association doesn't recommend a PVC roof for colder climates; the material can break in very cold temperatures, so it's always advisable to discuss this roofing option with a professional contractor before making a decision.
