We’re all bound to make mistakes – whether making a simple arts and crafts project or repairing something complex like a car engine.

However, some mistakes can be costly, especially considering the scope of work, cost, and direct implications on people and material. For instance, many people are prone to making mistakes when installing or repairing commercial roofs.

You may fail to work with industrial roofing experts or choose low-quality materials. Worse still, a lack of consultancy and expertise may lead to poor roofing designs, costing you money and time.

But, when working with experts, you can access best-of-breed products for your commercial roof design and installation at a fraction of the cost.

Here are common mistakes to avoid when considering a new commercial roof design.

  1. Dealing with water

The first and foremost consideration is dealing with water. As a general rule, most manufacturers want 80% of water off the roof within 48 hours of a rain event. To make this happen, there are a few solutions:

  1. Consider installing tapered insulation. This will help create a slight pitch toward roof drains / gutters / scupper boxes.
  2. Increase the size of your drain sumps.
  3. Cut water reliefs into your existing roof system
  4. Install additional drains, if it is possible to install new plumbing inside your building.
  5. Add new scuppers and/or gutters to the edge of your roof system.
  1. Wind load

The wind load is one of the most critical roof design considerations. All commercial roofs must withstand winds or uplifts to a certain degree. The degree to which your roof must stand up to wind is largely based on how tall your building is, how close to the water it is, how many obstructions are in the way, and so on.

Based on these conditions, a determination is made in regards to how many fasteners need to be installed, what is the best installation method (Adhered, mechanically attached or rhinobond) and what enhancements may be needed in the field, perimeter and corner of the roof system.

  1. Durability

Any commercial roof must be durable. Commercial roofs must withstand strong wind and drain any stagnant waters. The roof’s durability eliminates costly repairs associated with pools and hailstorms.

The commercial roof needs to stand for decades without being damaged by sunlight, debris, animals, heat, and heavy or harsh weather conditions.
