What to Do if Screws in Metal Roof Came Loose - ACR1

FLOYD MASON • Dec 27, 2022

If you notice that screws have become loose in your commercial metal roof, it is important to take action immediately. Loose screws can cause major damage if left unchecked. Immediately contact a professional contractor to diagnose the issue and help repair any problems with the screws or panels of your metal roof.

Reasons Metal Screws Come Loose

When a metal roof is installed, correctly applied screws are essential for the stability of the entire structure. If these screws become loose, it can lead to a variety of issues. The screws in a metal roof can become loose for a number of reasons, including:

Thermal Expansion/Contraction: As the temperature changes, metal expands and contracts. This can cause screws in a metal roof to become loose over time.

Poor Installation: If the screws were improperly installed, it could lead to them becoming loose quicker than normal.

Weather Damage: Severe weather conditions such as high winds and storms can place a lot of stress on screw fasteners, leading to loosening over time.

Deterioration or Corrosion: Poorly treated or aged materials are prone to corrosion which weakens the integrity of the screws in your metal roof.

Gasket Deterioration: If the rubber gaskets in your metal roof are not replaced, they can deteriorate over time and cause screws to become loose.

Compression due to Loading: If too much weight is placed on the roof, it can cause screws to become loose. Instances of heavy snowfall or ice can cause the roof material to sink, exposing the screws. Once it melts and the weight is lifted, the material will spring back, which can strain the screws and cause them to loosen.

How Do I Repair Loose Screws?

Replacing these loose screws with caulk is the first alternative to remedy this issue, but the best way to repair loose screws is to contact a professional commercial roofing contractor. They will inspect the roof for any damaged metal components or other parts of your roof and can also advise you on the best approach for repairing the loose screws. It’s important to choose a reputable contractor who has experience in metal roofing and understands how to properly install and maintain such roofs.

When hiring a contractor, be sure to ask about their knowledge of metal roofing and specifically what type of material they plan to use for the repair job. If possible, get references from previous customers so you can verify the quality of their work. Additionally, make sure that the contractor is licensed and insured in your state before beginning any repairs on your commercial property.

Common Reasons for Leaks in Metal Roofs

Leakage in metal roofs generally occurs when there are gaps between two adjacent panels or when proper sealing techniques have not been used during installation. Poorly installed flashing can also cause water intrusion by providing pathways through which water can penetrate into underlying layers of material. In addition, condensation may form within enclosed spaces caused by changes in temperature, which then leads to moisture buildup that creates leaks over time.

Lastly, poor maintenance practices, such as leaving debris on the roof, can contribute to leaks by blocking drainage channels which prevents water runoff from exiting properly.

How do Flat Roofs Drain?

13 Feb, 2024

Flat roofs can be a great choice for buildings due to their affordability and durability. However, if not done correctly, flat roofs are prone to water damage. Proper drainage is essential for the longevity of a flat roof, and selecting the correct drainage system is critical. Here we will discuss three common flat roof drainage systems - gutters, interior drains, and scuppers - as well as their pros and cons. Gutters Gutters are the most common form of flat roof drainage because they are low-cost and efficient when it comes to redirecting water off the roof. Gutters should be installed at a certain angle (approximately 1/4” per foot) to ensure proper water drainage. Gutters also need to be maintained over the years, as debris and leaves from storms or rain water can clog them up and create standing water. Pros: Low-cost installation and maintenance Easy to install Can direct water away from the foundation of the building Cons: Prone to clogging Requires periodic maintenance and cleaning Overflow from rain storms can cause damage to surrounding areas Interior Drains Interior drains are often seen as the higher-cost alternative to gutters. They are installed directly into the flat roof’s membrane and include a network of pipes that drain water off the roof into a downspout. Pros: Low maintenance More reliable than gutters in terms of preventing roofing damage Can be adjusted to fit any size of flat roof Cons: Expensive installation and maintenance costs compared to gutters May require frequent adjustments depending on the environment surrounding the building Can be difficult to install if the roof does not have the right slope Scuppers Scuppers are metal or plastic openings that allow water to drain off flat roofs. They generally come in square or rectangular shapes and are installed along the perimeter of a roof. The size and shape of scuppers should be adjusted accordingly in order to prevent water from overflowing onto the sides of a building. Pros: Easy and cost-effective installation Low maintenance costs compared to gutters or interior drains Can be adjusted to fit any size of flat roof Cons: Prone to clogging due to debris and leaves Overflow from rainstorms can cause damage to surrounding areas Can be difficult to install correctly if the roof does not have the right slope When it comes to selecting the best drainage system for your flat roof, there are a few things to consider. Gutters, interior drains, and scuppers all offer their own advantages and disadvantages. It is important to select the right drainage system for your needs in order to ensure the longevity of your roof and protect it from water damage.
