TPO Roofing Cost Factors
The causes of a rise in overall TPO costs differ. You might occasionally pay more to get the best materials and labor for your TPO roof.
However, knowing the information below in advance, you may be able to avoid excessive expenditure for a job.
How Thick Is the Insulation?
As standard insulation, several contractors will use a half-inch fiberboard. Board made of fiber has extremely little insulation value. It will cost you a hefty fortune to have insulation for a flat roof.
Insulation made of PolyISO rigid foam measuring one-inch thick costs $45–$50 per 100 square feet. Therefore, if you require an 18 R-value, three inches of ISO will be necessary, costing between $135 and $150 for every 100 square feet.
Due to the high cost of the ISO board, there is sadly no solution to lower this expense.
Curbs and Penetrations
Roof penetration delays installation and necessitates more materials and flashing. The contractor must make up for increased material costs and lost productivity.
Simple pipe flashings are less expensive and easy to handle. You should expect a $50 price tag for each pipe flashing.
You could expect to pay between $180 and $250 for drains. These are necessary on most flat roofs but need an expensive assembly.
Presence of an Old Roof
The old roof must be removed before installing the new TPO membrane. You will spend between $0.75 and $3.00 per square foot to have the old material removed, depending on its type and how many layers there are.
Among river rock ballast, BUR, gravel and tar ballast, and rubber, the last is the easiest to dispose of.
Plywood Replacement
Sometimes you discover rotten or damaged plywood boards under the old covering. You will have to change the old roof before fixing a new one. Each 4 x 8 piece of plywood will cost between $75 and $90.
The Thickness of the TPO Membrane and Color
Depending on the thickness of the TPO membrane you choose, your overall cost will vary significantly. This includes 45 inches (budget), 60 inches (mid-range), and 80 inches (premium).
Improved UV protection, better longevity, and improved puncture resistance are all benefits of using a thicker TPO roofing material which is more expensive.
Any color other than white will cost extra. The choices are also very constrained. Furthermore, the usual hues that don’t cost more are white, grey, and tan.
Labor
TPO roofing is expensive because it is a special flat roof material. As a result, it requires tools, installation expertise, and training.
Due to the lack of professionals for this work, installation costs are kept high. Since most installations are for commercial use, this is particularly true in the home sector. As a result, those who do usually charge more than standard roofers.
Commercial professionals frequently employ highly compensated non-union or union personnel. To cut expenses, residential contractors often use less-skilled workers.
Location
Local contractor labor costs can differ significantly.
You might anticipate paying more for the same installation if you reside in a high-income city than if you reside in a tiny town.
Getting an estimate from a local TPO roofing contractor is far better than the prices you find online. Don’t be shocked when you see this.
