Flat roofs are quickly becoming a more modern and efficient roofing choice for New England homes. While pitched roofs are more traditional, flat roofs offer a unique design and functional advantages. However, installing a new flat roof on your home requires the careful preparation and skilled craftsmanship that only a reliable roofing contractor can provide.
The experts at Dynamic Roofing Technologies have been installing, repairing, and maintaining flat roofs across New England for many years. We’re here to explain the benefits of a flat roof system for your home and what you can expect from the installation process.
Why Choose a Flat Roof for Your Home
Despite the name, flat roofs aren’t perfectly flat. Like other roofs, they require runoff and drainage for rain and snow. Those requirements mean flat roofs have a pitch, or vertical change in height, of 1-10 degrees, and never greater than 15 degrees. That’s enough to keep water from stagnating, while to all appearances the roof looks flat.
Flat roofs offer several benefits for homeowners:
- Modern aesthetic appeal: New homes, especially, look even sleeker and more modern with the clean lines of a flat roof.
- Efficient use of space: Many homeowners use their flat roofs as additional home space for things like solar panels, gardens, or HVAC units.
- Ease of maintenance and access: Flat roofs are just easier to walk on, making it safer for you to inspect or maintain your roof. (Or enjoy that rooftop garden!)
- Cost: Flat roofs require less material than traditional pitched roofs, often resulting in a lower upfront installation cost. And because they’re more accessible than pitched roofs, they’re cheaper to maintain or repair.
- Energy efficient: Pitched roofs necessarily create an open space between the bottom layer of the roof and the home, which may trap hot air in summer and cold air in winter. Flat roofs, on the other hand, are built with insulation that completely covers the top of your home to help reduce heating and cooling costs.
Preparing for Flat Roof Installation
Once you’ve decided that a flat roof is right for you, here’s what to expect before the installation process.
Roof Inspection and Assessment
Your roofing contractor will inspect the existing roof to assess its structure, drainage, and damage. This helps them determine whether you need a full roof replacement or an overlay on the existing roof.
Material Selection and Planning
Next, you and your roofer will discuss the best materials for your flat roof system based on your budget and your home’s needs.
Options include:
- EPDM: Flexible rubber material is glued to the roof substrate and adjacent areas. An EPDM roof can last 20 years or more with minimal maintenance.
- TPO (Thermoplastic Polyolefin): Flexible and ideal for variable New England climates. The material is heat-welded with reflective and Energy Star properties.
- Modified bitumen: Energy-efficient and reflective. Comes in 3’ wide rolls with self-adhering systems, so it’s easy to handle and apply without torches.
Scheduling and Preparation
Other pre-installation considerations include:
- Clearing your outdoor spaces and moving any vehicles from the immediate area.
- Preparing for noise and limited access to certain areas for a period of time.
- Reviewing timelines and weather considerations with your roof contractor.
The Flat Roof Installation Process
On the scheduled day, your professional roofer will typically follow these steps to get your flat roof installed with efficiency and expertise:
- Removing the old roofing system: Your roofing contractor will first safely remove old materials and inspect the decking for rot or other structural issues that must be addressed before a new roof can be installed.
- Repairing and preparing the roof deck: The roof base must be clean, dry, and level for proper adhesion.
- Installing insulation layers: These add thermal efficiency and help prevent leaks.
- Applying the roofing membrane: The chosen material is rolled out and sealed using adhesive (for bitumen) or heat-welding techniques (for EPDM or TPO).
- Sealing edges and flashing: This important step helps prevent water intrusion around vents, chimneys, and parapet walls.
- Final inspection: A good contractor will perform a final inspection once the process is done to check for proper sealing, slope, and drainage.
What to Expect After Installation
Once the initial flat roof installation is done, your roofer will typically perform the following:
- Cleanup and disposal: A quality contractor should remove debris and restore your property to its original condition.
- Final walkthrough: We recommend that you review the finished work with your contractor and ask questions about maintenance.
- Warranty information: Make sure you understand both the material and workmanship warranties for peace of mind.
- Initial settling period: Minor surface changes may occur as the roof adjusts to temperature and moisture levels. Discuss with your contractor what is considered normal and when you should call a professional.
Maintaining Your New Flat Roof
Your new flat roof should give you decades of optimal performance. Proper maintenance is key to a long lifespan.
- Schedule annual professional inspections.
- Keep drains and gutters clear of leaves and debris.
- Address ponding water or minor damage immediately.
- Avoid unnecessary foot traffic on the roof
