Low-slope commercial roofing, also known as flat roofing, is a popular choice for many commercial buildings due to its cost-effectiveness and practical design. In this blog post, we’ll look at ten facts about low-slope commercial roofing that every business owner should know.
1. Low-Slope Commercial Roofing
Low-slope commercial roofing, refers to roofs with a slope of less than 3:12. This means for every 12 horizontal inches, the roof rises less than 3 inches. These roofs are commonly used in commercial buildings due to their practicality and cost-efficiency.
2. Common Materials Used
There are several materials typically used for low-slope commercial roofing:
- Built-Up Roofing (BUR): Consists of multiple layers of bitumen and reinforcing fabrics.
- Modified Bitumen: A variation of BUR with added polymers for enhanced performance.
- Single-Ply Membranes: These include TPO, PVC, and EPDM, which are known for their durability and flexibility.
3. How Are Low Slope Roofs Installed?
Low-slope roofs can be installed using various methods, such as:
- Fully Adhered: Membranes are glued to the substrate.
- Mechanically Attached: Membranes are fastened with screws and plates.
- Ballasted: Membranes are held in place with gravel or pavers.
4. Advantages of Low-Slope Roofing
There are numerous benefits to low-slope commercial roofing:
- Cost-Effective: Lower material and installation costs compared to steep-slope roofs.
- Energy Efficiency: Often designed to reflect more sunlight and reduce cooling costs.
- Easy Maintenance: Easier to inspect and maintain due to the flat surface.
5. Potential Drawbacks
While low-slope roofing has many advantages, it also has some potential issues:
- Water Ponding: Improper drainage can lead to water accumulation.
- Leaks: More susceptible to leaks if not properly installed and maintained.
- Limited Lifespan: Depending on the material, it may have a shorter lifespan compared to steep-slope roofs.
6. Importance of Proper Drainage
Effective drainage systems are important for low-slope commercial roofing. This includes:
- Scuppers: Openings in the roof edge that allow water to drain off.
- Drains: Located in the roof surface to channel water away.
- Gutters and Downspouts: Direct water flows away from the building’s foundation.
7. How are Low-Slope Roofs Maintained?
Commercial roofing maintenance is essential to extend the life of a low-slope roof. Regular inspections and upkeep can prevent minor issues from becoming major problems. Basic maintenance tasks include:
- Debris Removal: Ensuring the roof surface is free of leaves and other debris.
- Inspecting Seams and Flashings: Checking for cracks or gaps.
- Checking Drainage Systems: Ensuring drains and gutters are clear and functional.
8. Energy Efficiency and Insulation
Low-slope commercial roofs can be highly energy-efficient with the right insulation and reflective coatings. These roofs often use:
- Polyisocyanurate (Polyiso): A popular insulation material with a high R-value.
- Reflective Coatings: Cool roofing materials that reflect more sunlight and absorb less heat.
9. Common Repair Techniques
When issues arise, several repair techniques can be used for low-slope roofing:
- Patching: Applying a patch to the affected area.
- Re-Sealing: Reapplying sealant to seams and flashings.
- Replacement of Damaged Sections: Removing and replacing damaged sections of the roofing material.
