Serving the greater Springfield area of Missouri, metal roof installation is an attractive and cost-effective choice for homeowners looking to upgrade their homes. While metal roofs provide protection and last longer than other roofing materials, there are several common mistakes made during installation that you should be aware of before beginning your project. Here, we’ll explore the six most common mistakes associated with metal roof installation in Springfield, MO.

1. Not Checking the Roof Structure

Incorrect Decking Assumptions

Before installing a metal roof, it is important to check the roof structure to make sure that it is capable of bearing the roof’s load. This step will include assessing the strength and stability of the existing decking as well as checking for any air gaps that could potentially be there from improper installation. Without checking the roof structure, you could risk not only compromising the quality of the roof installation, but also your safety.

Inadequate Sleeves, Z-Flashing and J-Flashing

Another important aspect to consider when assessing the roof structure is to check the number of sleeve, Z-flashing and J-flashing pieces needed to complete the project. These act as additional forms of protection against water ingress and can help prevent potential damage to the substrate underneath. It is important to use a sufficient number of these pieces so that the roof is properly sealed against dirt, debris, and moisture.

2. Ignoring Underlayment

Choosing the Wrong Type

When installing a metal roof, it is essential to select the correct underlayment for the job. If the wrong type of underlayment is chosen, it can cause the metal to corrode or rust prematurely. The most common types of underlayments for metal roofs are self-adhering materials and felt paper. However, other types such as rubberized asphalt may be better suited for certain types of metal roofs.

Avoid Installation Pitfalls

In addition to choosing the correct type of underlayment, it is also important to avoid common installation pitfalls. For instance, it is essential to overlap each layer of underlayment by at least six inches in order to ensure that water does not seep in through the edges. Furthermore, all edges should be sealed with a caulking agent or adhesive in order to prevent water penetration.

3. Not Installing Edge Flashing

Improper Seal at the Eaves

Edge flashing is an important component of metal roof installation as it helps to ensure that the eaves of the roof are properly sealed and water-tight. Without correctly installed edge flashing, the metal panels can become loose and create gaps that allow water to penetrate the roof.

Inadequate Sealing of Perimeter Edges

In addition to the eaves, it is essential to make sure that all perimeter edges of the roof are well sealed with either metal clips or sealant. These clips and sealants form an additional layer of protection around the roof, helping to prevent any water from seeping in and causing damage.

4. Overlooking Rigid Insulation Requirements

Inadequate Thermal Resistance

Installing rigid insulation beneath metal roofs is essential in order to ensure that the roof has adequate thermal resistance. Without this additional layer of insulation, colder temperatures can potentially cause the metal roof to contract and expand, resulting in metal panels becoming loose.

Insufficient Air Gap

In order to maximize the thermal performance of the roof, it is important to make sure that an adequate air gap is maintained between the substrate and the insulation. Without an adequate air gap, heat can become trapped beneath the roofing system and reduce the efficiency of the insulation.

5. Not Ventilating Attics and Layers of the Roof

Improper Airflow

One of the key mistakes that can be made during metal roof installation is to not include ventilation for the attic and other layers of the roof. Without proper airflow, the air temperature within the attic may become too hot or too cold, potentially causing the metal roofing panels to expand or contract.

Inadequate Releasing of Moisture

In addition to regulating the temperature within the attic, proper ventilation is also important for releasing any moisture that may accumulate beneath the roof. Without adequate ventilation, the moisture can cause structural damage to the roofing system as well as promote the growth of mold and mildew.

6. Not Cleaning the Metal Roof

Poor Drainage

It is essential to clean the metal roof before, during and after installation in order to ensure proper drainage. Without regular cleaning, debris and sediment may accumulate on the roof and clog up the gutters and downspouts. This can lead not only to poor drainage but also to damage to the metal panels over time.

Increased Risk of Corrosion

Finally, it is important to make sure the entire roof is regularly cleaned in order to reduce the risk of corrosion. The buildup of dirt and debris can lead to premature corrosion of the metal panels which can cause them to become weak and susceptible to damage.
