TPO Roofing Cost Factors
Diverse factors contribute to an increase in total TPO expenses. For your TPO roof, you might occasionally pay more to acquire the best supplies and labor.
However, by being aware of the facts below beforehand, you might be able to prevent incurring unnecessary costs for a job.
How Thick Is the Insulation?
Many contractors will use half-inch fiberboard as standard insulation. Fiberboard has incredibly low insulating value. Insulation for a flat roof will set you back a pretty penny.
One-inch thick PolyISO rigid foam insulation costs between $45 and $50 per 100 square feet. Therefore, three inches of ISO will be required if you need an 18 R-value, costing between $135 and $150 for every 100 square feet.
Sadly, there is no way to reduce this fee due to the high cost of the ISO board.
Curbs and Penetrations
Roof penetration causes installation delays and calls for more flashing and materials. Increased material costs and decreased productivity must be made up for by the contractor.
Simple pipe flashings are more manageable and less expensive. The cost for each pipe flashing should be $50.
For drains, you may anticipate paying between $180 and $250. The majority of flat roofs require them, although they require an expensive setup.
Presence of an Old Roof
Before putting in the new TPO membrane, the old roof needs to be taken off. Depending on the type and number of layers of the old material, you will pay between $0.75 and $3.00 per square foot to have it removed.
Rubber is the simplest to get rid of as compared to river rock ballast, BUR, gravel and tar ballast, and other materials.
Under the outdated covering, you may occasionally find rotted or broken plywood boards. Before you can install a new roof, you must first replace the old one. Plywood measuring 4 x 8 will cost between $75 and $90 per piece.
The Thickness of the TPO Membrane and Color
Your overall cost will differ greatly depending on the TPO membrane thickness you select. 45 inches, 60 inches, and 80 inches are all included in this (premium).
Using a thicker, more expensive TPO roofing material has advantages such as enhanced UV protection, increased durability, and enhanced puncture resistance.
Any color other white will incur an additional fee. The options are likewise very limited. White, grey, and tan are other common colors that aren’t more expensive.
Because TPO roofing is a unique flat roof material, it is pricey. It therefore needs tools, installation knowledge, and training.
The absence of professionals to perform this work keeps installation costs high. This is particularly true in the home sector because the majority of installations are for business usage. These who do typically charge more than typical roofers.
Highly compensated non-union or union employees are regularly used by commercial professionals. Residential contractors frequently employ less-skilled individuals to reduce costs.
Labor prices for contractors locally can vary greatly.
If you live in a high-income city rather than a small hamlet, you might expect to pay more for the same installation.
It is always preferable to get an estimate from a nearby TPO roofing contractor than to pay the pricing you see online. When you see this, don’t be astonished.
