Labor
Labor is a significant part of any home improvement project that can impact price based on various factors. Firstly, labor costs vary from region to region - local costs may be more or less depending on where you live. Additionally, if your project takes place in extreme weather conditions such as severe cold or heat, it's reasonable to expect higher labor costs. Similarly, specific climates may require roofing materials that can endure the rigors of heat, cold, and heavy storms and this may also affect labor time and cost.
Materials
Materials are one area where you may be able to control costs. Asphalt shingles are an affordable and excellent-quality option for most homeowners. They look great and protect the home without breaking the bank. They typically cost less compared to high-end alternatives like tile, slate, or metal. Of course, some more expensive materials may have a longer lifespan or you may prefer them aesthetically, but either way, there are plenty of options to fit most budgets.
Scope of project
Typically, price is calculated per square foot and depends on the unique characteristics of your house. In general, the more square footage your home has, the higher your cost will be, with steeper roof pitches resulting in more square footage on the roof. Additionally, the complexity of the roof, its pitch, and the ease of access for workers are all factors that can increase the final cost.
