Planning for a Roof Replacement

With all of the different parts of a roof and the decisions they entail, replacing a roof can be complicated and stressful. Knowing what to expect and how to prepare for it makes planning for a roof replacement much easier.

Parts of a Residential Roof

The essential parts of a residential roof are:

  • shingles
  • vents
  • weather barrier
  • ice and water shield
  • flashing
  • drip edge
  • gutter system

Every home is different: when replacing a roof, you might have to replace all of them or only two elements at most. For example, depending on the condition of the gutters and downspouts, it might be cost-effective to have them replaced at the same time as the roof.


The cost of a new roof depends on several factors including, material choice, amount of existing damage to the roof’s structure, the size of the roof, slope of the roof, and labour. It is recommended that you get at least three estimates from reputable roofing companies – this will give an idea of how to budget for your roof replacement.

Roofing Material

When replacing the roof, homeowners have two main choices when it comes to roofing shingles. They can go with what they already have or they can take the opportunity to change the look of their home by selecting a different style or color of roofing material.

Invest as much as you can in quality materials and products for three reasons. First, it will give you a feeling of security knowing that it will better protect you and your family. Second, quality materials tend to last longer. Third, when you do sell your home, it will increase its selling points if a home buyer knows that the roof has been replaced in the past 10 years and is still under warranty.

When and How Long

The best time to have the roof replaced is when the weather is most likely to cooperate. So, plan on replacing the roof during the spring, summer or fall.

The actual roof replacement takes anywhere from two to five days depending on the size of the roof, the roofing material, and the style of the roof. However, ensure that all required permits and necessary paperwork have been completed before work begins, including the contract you have with your roofing contractor.
