A good roof should last many decades, but it requires regular maintenance and proper insulation. Flat roofs require more maintenance due to their heavy weight and large areas that need covering with materials. The video “What Are the Best Material for a Flat Roof?” shows the various materials you can use for your flat roof.
Flat roofs are incredibly durable and maintenance-free. They can consist of nearly any material, but the most common choice is concrete coated with a breathable membrane such as asphalt shingles. These materials have advantages: asphalt shingles are inexpensive and easy to apply, but they need regular maintenance to maintain their durability and breathability.
Concrete flat roofs, on the other hand, require no maintenance but are more expensive than asphalt shingles. Concrete is a more durable material, withstanding damages better than shingles. It can be applied in two ways: casting concrete directly onto the roof or using an underlayment of plywood before pouring concrete onto the roof. Both methods require heating and cooling to apply correctly, and both are relatively expensive, but they are still more cost-effective than asphalt shingles in most cases. The choice between concrete and asphalt often relies on aesthetic preferences.
