Walnut Creek, United States - October 7, 2022 /Apollo Roofing Company/
Roofs are important to shield a building from exposure to natural elements that cause damage. So, to serve this purpose, roofs must be in good condition and regularly maintained and repaired. But sometimes, a roof replacement may be the only option because of age or irreparable damage.

The roof replacement cost depends on several factors. It is important to note that a roof replacement not only maintains a shield for the home but can also help save money in the long run by reducing energy bills and the need for repair. A roof replacement also increases a home's curb appeal and overall market value. The roof replacement cost must be seen in this light also as a kind of investment for the future.

Factors That Influence Roof Replacement Cost
1. Roof Size
The roof replacement costs depend on the size of the roof. The material required (shingles, plywood, underlayment) increases as the surface area of the roof increases. Though it differs from that of the roof, the square footage of a home can be used initially for rough estimates; it does not include garage space, interior walls, and basements. The initial square footage of a roof can be calculated by multiplying the length by the width (in feet) of all flat planes and calculating their sum, including walkways, garages, overhangs, front entryways, eaves, and overhangs.
2. Roof Slope
The slope of a roof may be steep, low, or a combination of both. Roof slope is the ratio indicating how many inches the roof rises for every 12 inches of horizontal length it runs. The steeper a roof, the costlier the roof replacement is. This is usually because steep roofs need more safety measures for the roofers working on them. The roof slope is also a contributing factor to the square footage of the roof. A roofing contractor will usually have slope factor charts that help calculate the square footage of the roof considering the slope.
3. Waste Factor
This additional amount must be added to account for the material lost around flashings and penetrations and for the material that overlaps in the roof valleys. Usually, roofers add around 10%-15% of the total area of the roof in square feet to account for material wasted. The waste factor calculation also depends on the roof style or roofing material used.
4. Roofing Squares
A roofing square is the area of the roof that is equal to 100 square feet. The total roof area divided by 100 gives the number of roofing squares needed for a project. The roofing square is the unit of measurement for the material used to cover the roof.
5. Roofing Materials
They have an obvious implication on the roof replacement cost. For instance, architectural shingles may not cost the same as traditional three-tab shingles. When shingles are replaced, the decking, vents, flashing, and underlayment may also need to be replaced. These also are of various price points based on the material, warranty, design, and other aspects. Choosing a roofing material may have to be based on geographical location and local building or neighborhood rules.
6. Roof Design and Shape
The style or design of the existing roof influences the roof replacement cost. The more complex the construction of the existing roof, the higher the replacement cost will be.
7. Condition of the Roof
The condition of the existing roof impacts the roof replacement. The more damaged a roof is, the more it will cost to replace it. When the roof’s underlying structure is also damaged, more labor and materials will be needed. Water damage may have affected the upper floors or attic when the roof is damaged. The total roof replacement of a badly damaged roof will be more expensive.
8. Location
The geographical area where the roof replacement is done also affects the cost. The roofing materials and labor costs will vary in different places. Some places like California may have material and installation specifications that have to be complied with to meet the requirements of the state or building or local energy codes.
9. Local Permits and Inspection
Local authorities may need to provide a permit for a roof installation or replacement. There can also be inspections done during the project. There are fees and costs incurred for this that must be included when estimating roof replacement costs.
10. Roofing Contractor Rates
The roofer will usually have a per-square-foot price quote that they provide initially, inclusive of materials needed and labor. The contractor may charge an additional amount for the removal and disposal of the old roofing materials, while the customer can check if there is an extended warranty that must be purchased separately.
