Replacing a roof can be a big investment since it will take a lot of time, money, manpower, and planning.

Temperature and Climate

There are certain roofing materials like asphalt shingles that are sensitive to certain weather conditions and temperatures.

The best time to install your new roof is during summer when the sky is clear and there are no interruptions from rain, snow, strong winds, and even hailstorms. 

Procuring Materials

It’s best to first have the right materials for the roof replacement before making any final decisions. One advantage of having your new roofing materials stored closely is that you can keep it in warmer temperatures which is ideal for roof installation during colder seasons. 

Estimated Time to Replace a Roof 

There’s really no definite time on how long a roof replacement will last since each roof has a unique area and each one is different from each other. Moreover, the climate has to be taken into account since heavy rain and storms could considerably delay operations. 

However, let’s assume that we’re replacing a roof of a 1,700 square feet roof, which is the average area of a roof in the United States. If there’s clear weather throughout the whole installation process and there’s no other factor that could impede operations, then this is the average time for each of the roofing materials.

  • Natural slate 6 – 7
  • Asphalt shingles 1 – 2
  • Steel sheets 3 – 4
  • Concrete tile 8 – 9
  • Flat roof 2 – 3
  • Synthetic slate 3 – 5
  • Wood shakes 3 – 4

At the end of the day, homeowners should expect their roof replacement to be finished in a week on average. Of course, homeowners will also have to keep in account the area of your roof, the materials that’s been installed and if the weather in the area is cooperating.
