What Is a Flat Roofing System?
As the name suggests, flat roofs are not flat! They have a slight slope to let water run down.
Common materials that are used for flat roofs are:
- EPDM Rubber Roofing
Long-lasting synthetic rubber roofing sheet that is applied to homes and commercial structures.
- TPO (Thermoplastic Polyolefin)
Reflective single-ply membrane that has established energy-efficiency credentials.
- PVC Roofing
Excellent chemical and moisture-resistant, strong, heat-welded membrane.
- Modified Bitumen
A roofing system that is an asphalt-based material covered by fiberglass or polyester.
- Built-Up Roofing (BUR)
A traditional system made of multiple asphalt and felt layers.
The systems all have different performance characteristics but are all designed to provide an impervious barrier over low-slope roofs.
Why Flat Roofs Are Popular in Rochester
There are a number of practical and economical advantages to using flat roofs.
Pros of Flat Roofing Systems
1. Lower Installation Costs
In general, the cost of materials and labor for a flat roof is less than for a steep-slope roof. The simpler design often results in lower upfront installation costs, making flat roofing an attractive option for budget-conscious property owners.
2. Easier Maintenance Access
Flat roofs can be accessed and maintained more easily and safely. As opposed to steep roofs, HVAC equipment, vents, and roofing elements can be located with ease by contractors, and maintenance will be easier, which can further decrease the cost of service.
3. Efficient use of space
The rooftop offered by flat roofs can be used for:
- HVAC systems
- Solar panels
- Outdoor seating areas
- Rooftop gardens
- Additional storage equipment
This is particularly useful in urban or commercial environments as space is limited.
4. Modern Architectural Appeal
Flat roofs give a neat and sophisticated look, which fits in well with modern structures. Conveyors are highly valued by many homeowners and developers for the contemporary appearance they offer for their homes and commercial buildings.
5. Faster Installation Time
Having a simpler design, flat roofs can be installed in less time compared to complex pitched roofs. The quicker it’s installed, the less labor time is needed and the less disruption for occupants, if any.
6. Energy Efficiency Potential
Some flat roofing membranes, especially reflective TPO and PVC roof membranes, can provide heat rejection in the summer months. This can help to reduce the amount of energy consumed and the cost of cooling in hot weather.
7. Suitable for Commercial Buildings
Commercial properties benefit from flat roofs as they make it easy for maintenance staff members to gain access and can be used to house large equipment on the roof. They are suitable for warehouses, offices, retail buildings, and apartment complexes.
8. Improved access to removing snow
Flat roofs enable snow removal by professionals if it becomes a problem in Rochester’s snowy winter months. This can be helpful in the management of excessive snow loads during heavy lake-effect snow events.
9. Lower Material Waste
In general, flat roofing systems generate less material waste during installation because there are large membrane sheets that cover wide areas. This can improve the installation’s environmental and economic impacts.
10. Adaptability for Additions
Flat roofs may be more easily adapted to building additions, upgrading existing rooftop equipment, and future building changes. They are simple in design and allow for flexibility in terms of changing property requirements.
Cons of Flat Roofing Systems
Although flat roofs have numerous advantages, they also have some serious disadvantages, particularly in Rochester’s climate.
1. Higher Risk of Water Pooling
Water drainage is one of the greatest Rochester flat roofing projects challenges. Drainage systems need to be designed and maintained correctly; otherwise, water may pool in low areas due to the low slope.
Standing water can cause:
- Leaks
- Membrane deterioration
- Mold growth
- Structural damage
2. More Frequent Maintenance Needs
Compared to pitched roofs, flat roofs need much more frequent checks and maintenance. All drains, seams, flashing, and membranes should be inspected on a regular basis to ensure that there are no leaks or water intrusion.
If routine maintenance is not performed, the roof could lose a lot of life.
3. Shorter lifespan than some pitched roofs
While modern flat roofing materials are expected to have a lifespan, many flat roofs will have a shorter life expectancy than premium metal or slate pitched roofs.
Typical lifespans include:
- EPDM: 20–30 years
- TPO/PVC: 20–30 years
- Modified bitumen: 15–25 years
4. Snow and Ice Challenges
Heavy snowfall can be a problem for flat roofs in Rochester. Snow does not slide off these roofs readily like steep roofs, where it does. Whereas on steep roofs, snow does slide off easily, it does not on these roofs.
This will lead to a higher risk of:
- Excessive snow loads
- Ice dam formation
- Wetted sections of the floor surface
Proper structural design and insulation are essential to handle these conditions.
5. Leak Detection Can Be Difficult
Leaks in flat roofs can flow under the roof surface and then manifest in the interior of a structure. This can make it more difficult to find and fix the leak.
Commonly, professional inspections are needed to accurately pinpoint problems.
6. Vulnerability to Punctures
Flat roof membranes can be damaged by:
- Foot traffic
- Falling branches
- Sharp debris
- Improper maintenance work
If not patched in a timely fashion, punctures can let water into the vehicle.
7. Drainage Systems Require Attention
Flat roofs depend a lot on drains, scuppers, and gutters to get rid of water. Build-up of rainwater in the drains can cause flooding and stagnation within a short period.
Cleaning is necessary regularly, particularly in the fall leaf season and after storms.
8. Potential for Higher Long-Term Maintenance Costs
Although the initial cost of installation might be less, maintenance and repairs can be costly over time. Property owners should plan to have periodic inspections and drainage maintenance, as well as membrane repairs.
9. Limited Attic Space
Typically, flat roofs offer less attic or storage space than pitched roofs. This can limit the flexibility of insulation and storage in certain homes.
10. Not Ideal for Every Home Style
Flat Roofs are ideal for contemporary and commercial designs. They can appear out of place on a traditional home or detract from the curb appeal based on neighborhood aesthetics and homeowner preferences.
Flat Roofing Performance in Rochester’s Climate
The climate of Rochester both poses opportunities and challenges for flat roofs.
Winter Considerations
In case of heavy snow and ice, the following is required:
