Demystifying the price of shingle roof replacement: Key factors to consider

Understand the elements that impact the cost of a re-roofing project

There are several factors that can influence the cost of re-roofing with asphalt shingles, including the challenges associated with the roof itself. These factors include the size and shape of the roof, the architectural complexity, the type of shingles used, the cost of labor, the cost of travel and the cost of removing the old roof. Let’s take a closer look at these factors.

1. The size of the shingle roof

The size of the roof is one of the most important elements in determining the cost of its replacement. A larger area will require more materials and more labor, which will increase the total cost of re-roofing. Most contractors charge by the square foot, so the larger the roof, the higher the cost.

2. Roof slopes and number of slopes

The slope and number of slopes of a roof is also an important factor to consider. A 2-sided shingle roof with a gentle slope is easier to work on and requires less labor and equipment, while a 16-sided roof with a steep slope of up to 24/12 will be more difficult and dangerous to work on, resulting in higher labor costs and the need for additional safety equipment.

3. Architectural structures

The presence of dormers, mansards, turrets, bay or bow windows, chimneys or other structures on the roof can also affect the cost of re-shingling an asphalt shingle roof. These structures can make the job more difficult and require specialized skills and tools to work around them or integrate them into the new roof.

4. The choice of materials

The type of shingles used is also an important factor in determining the cost of asphalt shingle roofing. There are different types of shingles, ranging from traditional 3-tab shingles to high-performance architectural shingles that can withstand winds of up to 210 km/hr. Premium asphalt shingles are of course more expensive, but they offer increased durability and weather resistance and a lifespan of up to 40 years. This means that you could save money in the long run by opting for premium materials. So it’s important to choose the type of shingles that best suits your budget and needs.

5. The workforce

Labor costs are another important factor in determining the cost of asphalt shingle roofing. They can vary greatly depending on where you live and the demand for roofing services in your area. It is important to compare prices from different contractors to ensure that you are getting the best possible price.

6. The distance of travel

Travel costs are also a factor to consider when re-roofing with shingles. If you live in a remote area, contractors may charge extra to cover travel costs. It is important to discuss these costs with potential contractors to avoid unpleasant surprises.

7. Removal of the old roof

When replacing a shingle roof it is essential to take into account the time needed to remove the old one. It is at this time that some surprises may appear that could not be detected at the time of the estimate and that may unfortunately generate additional costs.

Multiple layers of shingles
According to recommended standards, there should not be another layer of shingles underneath the one being replaced, especially if the roof has been re-roofed several times. However, it is possible that layers of shingles have accumulated over time, which can make it difficult to detect them when estimating costs. This can make removal of the old roof complicated and result in increased labor costs, as it is often difficult to remove the lower layers of shingles. Therefore, it is important to inform the estimator if you become aware of this problem.

The amount of debris
After the shingles are removed, especially if there were multiple layers of shingles to remove, the amount of debris generated may result in additional costs for disposal.

Damage to the structure
If the shingle roof was improperly installed or damaged, it is possible that damage was done to the structure of the house and is only visible when the roof is removed. This will obviously add to the total cost of re-roofing, as it will definitely be necessary to repair the structure before the new roof is installed.
