Cost Factors

Factors That Affect Your Cost Estimate

Accurate construction cost estimates take into account multiple factors. Depending on the type of product, factors such as construction type, manufacturer location and materials used can make a significant difference in the final estimate. Building types and the changing cost of construction materials can also generally affect price.


Skylight size, shape, and glazing options all factor into the final price estimate. Other factors include the type of structure (single story office building vs. high rise building), and building construction.

Wall Systems

Product sizes, choice of materials (metal, stone, wood, etc.), type of panel or system, and other factors significantly affect the cost of construction products in this category.

Roof Recovering

Estimates for materials to repair or refurbish a roof depend on the size of the roof and type of materials being used. Availability of specific membranes depend upon supply chain and product manufacturing.

Roofing Systems

Average cost estimates for roofing vary widely according to the type of roofing (metal, low slope, etc.), square foot cost, and if other components or materials are required to complete the commercial project.

"I have known about Walco and they have worked with me for over 30 years. I have always considered them the go-to company when I needed information or help with any of their products. I’ve received same or next day in person delivery of product data, samples, technical information and if that was not available, advice on other or similar products that might solve my problem, not to mention contact data for manufacturer’s reps. It’s always where I start."
