Flat roofs are a familiar choice for both commercial and residential buildings due to their visual appeal, cost-effectiveness, and the functioning space they offer. Here’s a specified overview of the types of Flat Roofing in Birmingham and how roofing contractors deal with them:
Types of Flat Roofs
Built-Up Roofing (BUR)
Composition:
BUR systems are composed of multiple layers of bitumen (asphalt or tar) alternated with reinforcing fabrics. These layers are then topped with a layer of aggregate, such as gravel.
Advantages:
Highly durable and resistant to heavy foot traffic, weather, and UV radiation.
Applications:
Usually used in commercial buildings but is also appropriate for residential use.
Modified Bitumen Roofing
Composition:
This type of roofing involves a single-ply rolled roof like BUR but with polymer-modified bitumen for added flexibility and durability.
Advantages:
Challenging to severe weather circumstances and easier to install and repair compared to BUR.
Applications:
Used in both commercial and residential properties.
EPDM (Ethylene Propylene Diene Monomer)
Composition:
A single-ply rubber roofing membrane.
Advantages:
Highly durable, flexible, resistant to UV rays, and can last up to 50 years.
Applications:
Broadly used in both commercial and residential constructions due to its sturdiness and comfort of installation.
PVC (Polyvinyl Chloride)
Composition:
A single-ply roofing membrane created from polyvinyl chloride.
Advantages:
Resistant to chemicals, fire, and punctures. It also offers energy efficiency due to its reflective surface.
Applications:
Popular in commercial buildings but also used in residential properties.
TPO (Thermoplastic Olefin)
Composition:
A single-ply membrane made from a mixture of polypropylene and ethylene-propylene rubber.
Advantages:
Heat-welded seams provide strong, durable, and reflective surfaces for energy efficiency.
Applications:
Increasingly popular for both commercial and residential buildings due to its cost-effectiveness and energy efficiency.
Green Roofs
Composition:
Layers of waterproofing, drainage, soil, and vegetation.
Advantages:
Environmentally friendly, improves air quality, provides insulation, and reduces the urban heat island effect.
Applications:
Used in both commercial and residential buildings, especially in urban areas.
How Roofing Contractors Deal with Flat Roofs
Initial Assessment and Inspection
Site Evaluation:
Contractors start by thoroughly inspecting the existing roof structure to assess its condition and identify any underlying issues.
Moisture Detection:
Using infrared scans and other technologies to detect moisture and leaks.
Load-Bearing Capacity:
Checking the roof’s load-bearing capacity is especially important for green roofs or when heavy equipment is to be installed.
Material Selection and Planning
Material Choice:
Contractors recommend the best roofing material based on the building type, climate, budget, and specific needs.
Custom Design:
Developing a custom design plan that includes drainage systems, insulation, and any additional features like skylights or HVAC systems.
Installation Process
Surface Preparation:
This involves removing the old roofing material, cleaning the surface, and ensuring it is smooth and debris-free.
Layer Installation:
For BUR and modified bitumen roofs, apply multiple layers of bitumen and reinforcing fabrics. For single-ply membranes like EPDM, PVC, and TPO, squash the material and protect it with glues or mechanical clasps.
Seam Sealing:
Ensuring all seams are properly sealed, particularly with single-ply membranes, which are often heat-welded.
Flashings and Edges:
Installing flashings and ensuring all roof edges and penetrations (vents, chimneys) are properly sealed to prevent leaks.
Quality Control and Testing
Inspection:
Performing a detailed inspection to ensure the roof is installed correctly and meets all specifications.
Leak Testing:
Conducting water tests to check for any potential leaks.
Wind Uplift Testing:
Ensuring the roof can withstand strong winds is particularly important for commercial buildings.
Maintenance and Repair
Regular Inspections:
Planning regular check-ups to classify and address any problems before they turn into major troubles.
Cleaning:
Keeping the roof spotless of debris, leaves, and other supplies that can origin water pooling and destruction.
Repairs:
Promptly addressing any repairs needed, such as fixing punctures in single-ply membranes or reapplying bitumen in BUR systems.
Resurfacing:
For BUR roofs, periodically add new layers of bitumen and aggregate to maintain durability.
Upgrades and Retrofitting
Energy Efficiency Upgrades:
Adding reflective coatings or installing green roofs to improve energy efficiency.
Structural Upgrades:
Improving the structural reliability of the roof to sustain extra equipment or features.
