Many homeowners assume shingles are the only major cost in a roof replacement.
In reality, a roofing system is made up of many different components, and the total cost is usually far more complex than most people expect.
So what is the most expensive part of a roof?
In most cases, the most expensive portion of the project is the roofing material itself, although labor is often very close in cost depending on the type of roof system being installed.
At Excel Roofing, we often explain to homeowners that a roof replacement is much more similar to a full construction project than simply “putting shingles on a house.”
There are dozens of components involved in building a proper roofing system.
When homeowners think about roofing, they usually picture shingles.
However, shingles are only one piece of the roofing system.
A full roof replacement may include:
The list can become surprisingly extensive depending on the complexity of the roof.
One of the biggest surprises for homeowners is how quickly roofing material costs increase.
Most people initially estimate roofing material costs based only on visible shingles, but the supporting system underneath often adds substantial cost.
For example:
In construction, there is an old saying:
“It is always more material than you think.”
Roofing is no different.
In many standard asphalt roofing systems, labor and material costs are relatively comparable.
However, material costs often edge higher depending on:
Roofing labor is highly skilled and physically demanding work, but modern roofing materials themselves have also become significantly more expensive over the last several years.
The type of roofing material selected has a massive impact on overall project pricing.
Standard asphalt shingles are typically the most affordable option.
However, premium roofing systems such as:
can dramatically increase both material and labor costs.
The more specialized the roofing system becomes, the more fabrication and technical installation expertise is required.
When working with high end metal roofing systems, the work often moves beyond traditional roofing and becomes closer to custom metal fabrication.
For example, specialty roofing systems may require:
This type of work requires:
As a result, both labor and material costs rise substantially.
Two roofs with the exact same square footage can have dramatically different costs.
Factors that increase roofing costs include:
The more complicated the roof system, the more labor hours and custom materials are required.
Sometimes the most expensive part of a roof replacement is not even visible until the old roof is removed.
If damaged decking or structural problems are discovered, additional repairs may be required such as:
These repairs can significantly increase the final project cost depending on the condition of the home.
Homeowners should be cautious of roofing estimates that seem dramatically cheaper than others.
In many cases, low bids may involve:
A roof is a complete system, not just shingles nailed onto a house.
Missing critical components may reduce the lifespan of the roof or create major leak problems later.
The most expensive part of a roof is usually the material itself, although labor costs are often very close depending on the roofing system being installed.
As roofing systems become more specialized, especially with metal, tile, slate, or stone coated steel products, both material and labor costs rise significantly due to the complexity and fabrication involved.
