This guide will discuss different types of roofing materials and their advantages and disadvantages so you can make an informed decision about your garage.

Types of Roofing Materials for Sloped Roof Garages

Galvanised Steel Roofing Sheets

Galvanized steel roofing sheets are popular for sloped roof garages due to their durability and long lifespan. They are corrosion-resistant, making them highly resistant to rusting or weather damage. This helps the roof to last up to 30 years. Galvanized steel roofing can also be painted or coated with various colors or finishes, allowing you to customize the look of your roof.

Installation is relatively straightforward, and many homeowners take on this job themselves. Steel roofs are also lightweight, making them easy to handle and transport.

On the downside, Galvanized steel roofs are noisy without a sound-dampening material. So that is an additional cost if you want less noise in your garage.

Fire Cement Roofing Sheets

Fire Cement Roofing Sheets are ideal for homeowners living in areas with high levels of salty sea air and humidity. This roofing material is made from dust, debris, and fire-resistant materials, which helps protect your home from the elements. It is also UV resistant and stands up to extremely hot temperatures.

The corrugated style of the fire cement roofing sheets allows quick water drainage and offers superior protection from high winds. They are easy to install and require little maintenance. Fire cement roofing sheets also come in various colors, so you can find one that best suits the exterior of your home. However, the cost per square foot is higher than other roofing materials.

Bitumen Roofing Sheets

Bitumen roof sheets are one of the oldest roofing materials. They can last for many years and provide reliable protection against the elements. Their seams are sealed with heat, creating an extra layer of waterproofing that ensures your roof is secure from leaks.

Installing bitumen roof sheets includes flaming to melt the sheets onto the roof, forming a strong and reliable bond that will not come loose for several years. This process creates a seal around each sheet, preventing water from entering your garage and causing damage.

The textured surface protects against UV rays and other weather conditions. Depending on the application, they can be adapted to various areas of the house and come in corrugated or flat sheets that look like shingles.

Since installing these sheets is dangerous, you should hire professional roofers, which will add up to the cost of bitumen roofing sheets.

EPDM Rubber Roofing Sheets

EPDM (ethylene propylene diene monomer) rubber roofing is an increasingly popular choice for sloped roof garages because of its affordability and durability. The material is made from synthetic rubber and can be applied in either large sheets or smaller strips. The rubber finish provides a smooth, shiny surface that looks better than most roofing materials. It is highly resistant to weather damage, including rain, snow, sleet, hail, and ultraviolet rays.

It is also flexible enough to withstand expansion and contraction due to temperature changes, making it a great choice for areas with extreme weather conditions. With proper maintenance, EPDM rubber roofing can last up to 50 years, so you won’t have to worry about replacing your roof too often.

Usual EPDM roofs problem arise when the bonding agent breaks due to weather conditions. Installing them is also difficult as they need perfect weather for proper installation.

Weighing each roofing material’s properties against each other to see what fits your needs and budget is the best way to know which is best for your garage.

Galvanized steel may be the most affordable option, while EPDM rubber is the most durable. Fire cement offers superior protection in areas with salty sea air, while bitumen is a classic look that has stood the test of time. Whichever you choose, make sure it meets your needs and fits into your budget.

You can also reduce costs by considering the angle at which the roof should be installed. If your area experiences less rain and snow, installing the roof at a lower angle will do the job, requiring less material. You can calculate the difference in a slope using the rate of change calculator to know how much cost you can save.
