There are different costs to consider when the time comes to update your commercial roof. There is the upfront capital investment, as well as long-term maintenance and lifecycle costs.
An investment in a high-quality commercial roof with excellent workmanship may minimize future maintenance and repair expenses, and it may last years longer than a roof constructed with lower-grade materials and unskilled labor. On the other hand, the number of years you intend to occupy the building may also influence your thought process.
When it comes to commercial flat roofs, there is no “one-size-fits-all” solution. To maximize performance, value and longevity, it is vital to customize a roof system that works with your unique building.
Costs to Consider
To determine the overall cost of your project, a thorough commercial roofing company will consider a variety of questions before submitting a proposal.
How large and detailed is the roof?
Of course, the overall size of your roof impacts cost. The number of roof penetrations is also a factor, particularly with a single-ply membrane roof. Roof vents and other features require careful sizing and cutting of the membrane, which affects labor costs.
Does the existing roofing have to be torn off?
When the sub-structure is sound, it might be possible to install a commercial roof right over the existing one. This eliminates the cost of a tear-off and significant debris removal.
However, if your existing roof is unstable or saturated with excess moisture, a tear-off is necessary. If your building already has two roof systems in place, they will have to be torn off before work can proceed.
Local codes don’t allow a third roof to be placed over the existing two. In this case, an ERC Wind Vented Roof is the best option because they dry out wet roofs and can be installed over existing multi-layer roofs.
Are repairs to the sub-roofing necessary?
Long-term moisture intrusion may have corroded or rusted metal or rotted wood to the point that parts of the structure must be removed and replaced before a new roof installation can proceed. The cost to replace deteriorated roof decking or framing can vary.
However, if the substructure is in good shape, all that is needed is the installation of recovery board over the existing roof or cleaning the existing surface. These steps are often accomplished at a relatively low cost.
What about insulation?
To maximize energy-efficiency, a layer of Polyiso or EPS is sometimes applied before the installation of a single-ply membrane roof. The thickness of insulation impacts upfront costs, although thicker insulation may further reduce long-term energy costs.
Any additional special flashing materials and the time it takes to properly flash a roof penetration also influence cost.
What does the new roof itself cost?
A building owner will often try to strike a balance between their current budget and a desire for a long-lasting, low-maintenance roof system.
Popular single-ply roof membranes like TPO and EPDM are available at a reasonable cost, and routine roof maintenance expenses are usually minimal for many years. Light-colored membranes can reduce energy costs by reflecting more sunlight away from the structure.
What about the quality of materials?
Higher quality materials may slightly increase upfront costs while reducing long-term maintenance and repair expenses. Duro-Last’s custom-fabricated, single-ply PVC roofs are excellent. Carlisle’s TPO, EPDM and PVC roof systems are also top options.
ERC is another dependable company that has developed top-tier products, such as revolutionary wind-vented systems. These roofing systems have a reputation for saving building owners a lot of money upfront, as this roof typically costs much less than the average roof.
Are current code requirements a factor?
For both safety and longevity, a reputable commercial roofing company will always insist that the work is up to code. You may find that codes have changed since your the last roof system.
Choosing a high-quality, customized roof system installed in full compliance with local regulations provides long-term savings and peace of mind.
What about warranty costs, if any?
It is possible to mitigate long-term costs by selecting a roof system with an excellent warranty or by investing in a special extended warranty.
Pay attention to the warranties offered. Even though a properly installed commercial flat roof will often last for many years, a “standard warranty” from a non-certified roofer may last for as little as five years.
By contrast, a solid warranty reduces year-to-year budgetary surprises for years to come. Top manufacturers like Duro-Last, Carlisle and ERC support their roof systems with appropriate warranties.
Simply maintain the discipline to have semi-annual or annual roof inspections to keep your warranty in force.
