Materials used for roofing aren’t cheap, especially if you are installing a large and complex roof. Material and style are just part of the quotation, professional labour often accounts for 50% to 60% of the total roofing cost.

The average cost of your labour varies depending on your choice of material. Wood shakes, tiles, and slate tends to be more expensive to replace than asphalt shingles. Additionally, the cost of labour is also affected by the shape and pitch of the roof.

Roofs with very deep pitches and complex shapes often require more materials and longer working hours to remodel hence pushing up the average cost of labour.


Other than labour, roofing materials, and roof types, correct timing can also have an impact on the total cost of your roof installation.

Most professional roofers are often busy in the late summer and autumn. Scheduling your roof installation or repairs in spring or late winter can attract lower prices or off-season discounts.



The cost of roofing materials and the roofer’s requirements usually vary in different regions. Some may require protective roofing materials from strong wind, extreme heat or cold while other regions may not require additional protective material, which means your total cost may be lower or higher than the standard national average cost.

How to prevent roof damage

Roofs are bound to deteriorate with time, but the bulk of roof damage is caused by external factors such as wind, debris, rain, excessive moisture, inadequate attic insulation, ice dams, snow, and many more.

While some of this damage may not be preventable; for example, extreme weather. It can damage your roof even if you take all the necessary precautions.

However, there are general ways in which you can prevent the unnecessary damages to your roof such as;

  • Install attic ventilation and insulation to help cool the roof and prevent ice dams respectively.
  • Regularly clean your gutter to remove any debris.
  • Cut down or trim dead tree limp surrounding your house to avoid collisions when they fall off.
  • Timely remove the moss, ice, and snow from your roof.
  • Replace or repair any damaged parts on your roof to prevent water from infiltrating and damaging the surrounding areas.
