One of the most on-demand roofing options on the construction market right now is metal roofing. If your current house roof has reached the end of its lifespan and you're planning to replace it with metal roofing, there are various factors that will impact the cost of the roof renewal.
Here's a look at some of the key variables to consider.
Roof Dimensions
The square footage – the length multiplied by the width – of your roof is one of the key things that metal roofing contractors consider when calculating the cost of your roof replacement. The larger the roof, the higher the cost, generally speaking. The measurements, often referred to as roofing squares, determine the cost of the roofing material, as well as the amount of labour required.
For easier calculations, most roofing material suppliers align the material sizing with the roofing square unit, thereby making it easier to estimate the amount of material required.
Roof Design and Pitch
Ease of access and pitch affects the ability to remove the old roof and laying the new roofing material. It does affect the cost of roof renewal, as it impacts the speed and skills required to install your roof. Steep roof designs are harder to work on and need skilled personnel, and in some cases, machinery such as cranes. The slope also determines the type of underlying system to install, which also affects the cost.
In the same vein, the roof profile affects the speed and skills required. Straight regular sections are easier to replace, while intricate designs, as well as valleys and peaks, are more challenging. Valleys require special equipment and work – this all adds to the final cost.
Roof Removal and Disposal
Before a new metal roof can be installed, the old roofing material may need to be torn off. In such scenarios, the cost of the roof removal will need to be included in the total costs of the roof replacement.
The type of roofing material and the number of layers that need to be torn off will affect the cost of the roof replacement. Roofing materials such as traditional asphalt roof shingles require more technique and time to remove than newer roofing materials such as metal roofing. Also, multiple layers require more time to remove, and this significantly increases labour costs.
The nature and weight of your old roofing material, as well as whether or not your old roofing material is recyclable, will also affect waste disposal costs associated with your roof renewal.
Metal roof replacement improves the appearance, functionality and value of your house. However, it should be well within your budget. Without an accurate cost estimate, the cost of roof renewal may escalate significantly. Ensure you get a written quote from your preferred metal roofing contractor before committing to hiring them.
