The roof over your head is an integral part of the engineered structure and defense of your home. When it comes to the materials used for flat roofs it is imperative to make the right choice.
Whether building a new home or replacing a flat roof, this guide will help you choose the right materials. Outlined and discussed below are deciding factors and benefits that should be considered in clear, easy-to-understand language.
Understanding the Impact of Different Materials
Before we talk about the different kinds of materials for flat roofs, it's essential to understand why your choice is critical. Each roof material has different benefits, and these are the factors you want to consider:
Durability: The materials will determine how long your roof will last—some shingles and membranes last longer than others, which saves you money over time.
Energy Efficiency: Some materials can help control your property's temperature, saving you money on heating and cooling.
Maintenance Needs: Different materials require varied amounts of care. How much time and work you have to put in depends on the type of roof you choose.
Cost: Depending on your chosen materials, the upfront cost and cost over time will vary. So if you plan to move in five years, you may consider a different flat roof material than if it's your dream house that you'll live in forever
Types of Flat Roof Materials
Let's look at the most common materials for residential flat roofs, what they are made of, and the pros and cons of each one.
Built-Up Roofing (BUR)
BUR roofs comprise layers of roofing felt, asphalt, and bitumen. Here are the benefits and drawbacks of this material:
Pros:
- Proven to be very strong.
- Excellent water-proofing qualities.
- UV rays can't hurt or degrade this material.
- Insulation can be used with it to make it more energy efficient.
Cons:
- Installation can take a lot of work.
- Heavier than some other materials, which could mean your roof structure needs more engineered support.
- Since asphalt is used in this product, there are more eco-friendly choices.
Modified Bitumen Roofing
Asphalt and rubber additives or plasticizers are used to make modified bitumen roofs. Read the benefits and disadvantages of modified bitumen:
Pros:
- Solid and long-lasting.
- Good weather and UV ray resistance.
- It can be set up as a multilayer system for extra protection.
- Installing it as a DIY project is possible for savvy or handy owners.
Cons:
- Installation may get messy and requires specific tools.
- There are only a few color choices.
- If not taken care of properly, they can get holes.
Single-Ply Membrane Roofing
Single-ply membranes are usually made of one of three materials: PVC, EPDM (rubber), or TPO (thermoplastic olefin). Here are the advantages and disadvantages of a membrane roof:
Pros:
- Easy to assemble and not heavy weight on your structure.
- Most chemicals and UV rays don't affect this membrane.
- Low need for maintenance – typically cleaning it periodically.
Cons:
- Compared to other materials, it may not last as long.
- It is possible to get punctured and damaged by falling branches.
- The quality of installation dictates how long it will last.
Metal Roofing
Steel, aluminum, copper, or zinc are some metals used in the production of metal roofing systems. Read the pros and cons of a metal roofing system:
Pros:
- Incredibly long-lasting, often 50 years or more.
- A surface that reflects light and lets less heat in.
- It can't be burned, eaten by bugs, or rot.
- Good for the environment and can be recycled.
Cons:
- Costs can be higher at first than with other materials.
- Professional installation specialists are often needed.
- It can be noisy when it rains.
Green (Vegetative) Roofing
Green roofs have a layer of plants, a growing medium, and a membrane that keeps water out. Learn the benefits and issues associated with a green roof:
Pros:
- Excellent insulation, which saves money on energy–heating and cooling costs.
- Aesthetic appeal and benefits for the environment, such as better air quality.
- The roof will last longer because it will be protected from UV rays and changes in temperature.
Cons:
- Installation and maintenance are hard to do.
- Upfront costs can be high and prohibitive for some projects.
- The structure must support the weight of the green roof system.
Considerations When Choosing Your Roof
Now that you know the different options, how do you select the right residential flat roof material for your home? Here are some key distinctions and factors to consider before making your final decision:
Climate: The weather in your area is a significant factor in choosing the right material. Some materials, like metal, work well in all kinds of weather, while others might be better for certain types of weather.
Budget: Determine how much you will spend on your roof. Even though some materials cost more initially, they may save you money in the long run because they last longer and use less energy.
Longevity: Think about how long you want to live in the home. If you plan to keep it for a long time, choose a more durable material.
Maintenance: Be honest about whether you want to and can take care of your roof. Some materials, such as green roofs, need more care than others.
Energy Efficiency: If lowering your energy bills is important to you, look into materials like green roofing or metal roofing that reflect light.
Aesthetics: How your roof looks is important, especially if it can be seen from the street. Choose a material that goes with the style of your home and your tastes.
Local Regulations: Check your local building codes and rules to ensure the material you want to use meets all the requirements.
