Ensuring optimal drainage capacity for a metal roof is crucial for maintaining a comfortable living environment. No one wishes to encounter water leakage from the ceiling, which can lead to interior damage. To prevent such issues, it’s essential to redirect water away from the building’s exterior and towards designated drainage areas, such as roof drains. While roof drainage systems are effective at their core, they often receive inadequate attention. This article provides a comprehensive guide for replacing the drainage mechanism on a metal roof and installing an improved roof waterproofing system.
Metal roofs come in various colors and styles that can enhance the aesthetics of ordinary houses, regardless of their architectural design. Although metal roofs are generally pricier than asphalt shingles, they offer a lifespan at least twice as long as traditional roofing tiles. Furthermore, metal roofs provide added protection against fires and can withstand wind speeds of up to 140 miles per hour. Gutter guards can be seamlessly integrated into almost all types of metal roofing systems. However, before selecting a gutter guard, certain factors need to be considered.

Size and Placement of Gutters
Metal roofs facilitate faster drainage compared to roofs covered with porous materials like asphalt shingles. Additionally, the thickness of metal roofs can raise their surface level. Both factors may potentially overload the gutter system or cause excess runoff during heavy rain. It’s recommended to use a 5 to 6-inch gutter and position it as high as possible without compromising the necessary slope for efficient drainage. If runoff issues are already present, installing gutter guards could worsen the situation. Therefore, it’s vital to choose a guard that doesn’t obstruct water flow through the drain.
Safety Precautions for Working at Heights
Before embarking on the installation of gutter guards on a metal roof, it’s imperative to understand the proper safety protocols for working at elevated heights.
Working at heights entails inherent risks, regardless of the perceived likelihood of falling. Here are some safety precautions to observe:
- Avoid arbitrary removal and use of equipment parts.
- Ensure the ladder’s strength and stability; provide anti-skid measures.
- Implement protective measures for equipment and surfaces, especially when dealing with asbestos tile ridges.
- Have on-site safety supervision during elevated work.
- Standardize disassembly procedures to prevent dropping objects.
- Discourage casual walking and climbing; follow designated paths and escalators.
Installing Gutter Guards on a Metal Roof
Once familiar with safety guidelines and equipped with necessary tools, you can proceed with installing gutter guards. Follow the steps outlined below to ensure proper installation for an effective and secure gutter guard system.
- Clean Existing Gutter Guards
Before initiating work, if your metal roof already has gutter guards, the first step is to clean the existing drainage setup. Exercise caution during cleaning, as metal roof gutter systems often accumulate algae over time, making surfaces slippery. Wear thick gloves to protect against sharp edges and potential cuts.
- Secure Mesh in Place
After cleaning the gutters, determine the required number of mesh pieces. Leave extra mesh on both ends of the eaves, around 20-30 cm. Secure the guards using pre-drilled pilot holes provided with the kit. Use approximately 250mm self-drilling screws to fasten the decorative strip. Repeat this process until the entire gutter is covered.
- Cut Mesh and Install Saddles
Create a 40-50 mm cut in the mesh at the upper part of each roof ridge to ensure proper mesh alignment with the metal roof profile. Attach the saddles to the roof using screws. Avoid over-tightening the screws to facilitate potential replacements.
Upon completing these steps, you’ll have successfully installed new gutter guards for your metal roof. If you’re considering further enhancements to your metal roof, continue reading below.
Starting Your Metal Roof Project
For standard house renovations, you can directly approach a reputable metal roof supplier to purchase the necessary materials. Opt for businesses with solid reputations and excellent service, as metal roofs have long lifespans and reliable businesses can offer post-purchase assistance, such as honoring warranties after five years.
Metal roof suppliers often invest in metal roof machines to manufacture various types of metal roofs and expand their commercial offerings.
