5 Factors that Influence Roof Replacement Costs

June 30, 2017

Roof replacement, though a cost-intensive home improvement commitment, delivers sizable returns in the long run, provided the job is executed by a competent roof replacement company and the investment is optimally utilized. Therefore, when you reach out to roof replacement companies for quotes, it is important to ensure you have a fair idea about the key factors that will influence the cost of the project. Read the blog post to learn about five such factors.

1. Size

Size of the roof is the biggest factor driving the cost, as roofing companies install roofing on a per square basis. The roofer takes measurement on square footage and divide the number by 100 to calculate roofing square. One roofing square equals 100 square feet. If, for instance, the roofer would work on a 4,000 square feet roof, it will break it down to 40 squares to calculate the price.

2. Pitch or Slope

Slope or pitch of the roof is another key factor that determines the cost of a roofing project, for two reasons:

1 – A steep roof that is more than 6:12 pitch is not walkable, which means it needs more safety, staging, and labor for replacement work.

2 – The type of underlayment system required for the roof is determined according to the roof pitch. A composition shingle roof, for instance, between 2:12 and 4:12 pitch requires dual layers of underlayment system; whereas, a flat roof between ½:12 and 2:12 pitch may require an underlayment that provides it Class-A fire rating.

A roof of 7:12 or greater pitch is steep and the roofer might charge extra as replacement is more difficult and insurance charges could be more in comparison to lesser-steep roof.

3. Type

The roofing type you choose not only decides the weight, durability, design, and longevity of the roof, it also plays a key role in deciding its cost. TPO, PVC, EPDM are three common roofing material types used in construction – each having its own advantages. EPDM, one of the most advised roofing systems for flat or low-slope roofs, has a high weather resistance with an average installation cost of $4.00 to $6.00 per square foot. PVC roofs are strong and durable, and some even come with lifetime warranties. TPO roofs are slowly gaining popularity as they have features of both PVC and EPDM roofs. The cost of installing a PVC or TPO roof is about $5.50 to $7.50 per square foot.

4. Addons

If you want a sustainable roofing solution, you would need to spend extra money. Roof coating, for instance, reduces energy bills and provides UV and water resistance, thereby extending the lifespan of the roofing system. Similar is the case with other roofing addons such as installing solar roof or going green. Both solar and green roofs may significantly reduce your energy bills, but do need an initial investment. Moreover, if you plan to go for a green roof, you also need to factor in the future maintenance costs when calculating the total cost of the modification.

5. Warranty

Roofs with standard roofing warranty are cheaper than those with extended or no-dollar-limit warranties backed by the manufacturer. When you choose for extended manufacturer’s warranty, you may have to pay for the additional material, and for the periodic inspections the manufacturer may demand to maintain the warranty. All in all, if you opt for a roofing system with extended warranty, know that the decision will reflect in the overall cost of the project.

Last Few Words

Roof replacement always demand a notable investment that pays off in full only if the roofing system is maintained properly. Make sure to check the condition of the roof at regular intervals, or better, hire a competent roofing company to conduct periodic inspections and address all issues as they arise.
