Flat roofs, known for their numerous advantages, make them one of the most preferred and long-lasting options. Frequently seen in commercial properties and multi-unit residential buildings, flat roofing systems require simple maintenance only. The structure of flat roofs provides owners with sturdy protection and the room to utilize their roof sections in multiple ways.
However, over the years, flat roofs also develop issues like any other thing. When the time comes to replace flat roofs, several factors come into play. The moment arises for thorough research and careful consideration of a range of factors and, most importantly, cost factors. This is where guidance from the roof company will help you sail through.
If you are a property owner considering
replacing flat roof, whether due to an urgent requirement or just a sensible enhancement, then you must evaluate the price segments of flat roofs in detail. In this blog, we are going to discuss the price segments of various types of flat roofs and the factors affecting those prices.
The cost for replacing a flat roof generally ranges from $3 to $15 per square foot, resulting in a total average cost of $4000 to $20,000. However, this cost varies depending on the size of the roof and materials. Keeping that in mind, here we enlisted different types of materials with price ranges to mull over when replacing a flat roof.
This roofing is known for exhibiting remarkable resilience to harsh environmental conditions and UV radiation. Apart from being suitable for a variety of climates, bitumen roofing material is also inexpensive. The installation costs for Modified Bitumen ranges between $4 and $8 per square foot. Its overall price structure ranges from around $4,900 to $14,600.
Metal flat roofs are favored by many due to their versatility, aesthetic appeal, and longevity. An average flat metal roof replacement costs anywhere between $4000 to $16,800 on average, making it $3 to $11 per square foot, depending on the size and material of the metal roofing you choose.
Built-up roofs (BURs), commonly referred to as tar and gravel roofs, consist of between three and six layers of water-resistant sheets made from asphalt, tar, and felt. These layers are topped with a layer of rocks or gravel for added protection. A tar and gravel roof replacement costs around $4.50 - $9.50 per square foot.
Thermoplastic polyolefin (TPO) roofing, a type of synthetic material, is a popular choice for commercial buildings due to its watertight properties and durability. It is known for its capability of lasting several decades. Easy and lightweight, TPO requies minimal maintenance. When combined with materials and labor, the average cost per square foot of TPO ranges between $3 and $14.
Rubber roofing costs between $4 and $10 per square foot when installed, which amounts to $6,000 to $16,000 on average. If we're looking specifically at EPDM roofing, the material itself costs between $0.50 and $3.50 per square foot. Additionally, you'll need to account for the cost of labor for replacement, which typically runs from $3 to $7 per square foot.
With installation included, the cost of Polyvinyl Chloride (PVC) roofing ranges from $5 to $12 per square foot. Although PVC is the priciest option among rubber roof types, it offers superior durability, with an average lifespan between 20 to 30 years.
Installing a fiberglass flat roof typically costs between $3.50 and $7.50 per square foot. This type of roofing is renowned for its durability, lightweight nature, and waterproof properties. However, it may not be the best option for larger roof areas. A GRP roof has a considerable lifespan, lasting anywhere from 25 to 50 years.
Since we have taken a brief insight into the range of flat roof replacements and the costs involved. Let's dive into the components that portray a crucial role in deciding the final price to replace a flat roof. Read on to learn about those factors affecting the cost of replacing flat roof:
Roof complexity - If your roof design is complex and requires multiple penetrations or hard to reach areas, then you may have to spend a little more on labor costs. As this complexity requires additional work.
Stories:
Another factor is your house's number of floors or decks. Particularly in commercial buildings, this leads to increased expenses on labor and materials as working on higher floors involves more risk and effort.
Application Method: Different roof attachment methods have varied costs. Ballasted roofs use rocks or gravel to hold down the roofing material, mechanically fastened roofs use metal plates and screws, while adhered roofs use glue or self-adhesive. The latter typically costs more.
Region/location:
Certain materials perform better in specific climates. TPO, built-up roofs, and PVC are suitable for hot climates, while EPDM and modified bitumen are ideal for cold climates. Meanwhile, metal and concrete roofs perform well in both.
Flashing & Parapet walls:
The cost of repairing or replacing a roof flashing or parapet (a low protective wall often covered with a metal cap) and its surrounding can add to the overall expenses.
Ventilation & Roof Drains:
The installation of a roof vent aids in regulating the attic's temperature and humidity. Installation of a roof drain helps in preventing water pooling. This is another prominent factor that adds to the costing of roof replacement.
Replacing flat roof is a significant investment, so you'll want to consider the above-given factors carefully. We suggest you always get quotes from multiple contractors and ask for a detailed breakdown of costs to ensure you're getting a fair price.
