Asphalts are roof of choice by people in non-tropical areas. This is due to their reaction with chemicals. Asphalt roofs are not as reliable as other roofs but their simple structure is easy to build and mass-produce. While other roofs are optimized to keep out rain despite the cost, asphalt roofs are more affordable. This type is chosen by those with limited funds when building a house.Asphalt roofs have a darker, cooler color than most roofs. Its color varies from one tile to another, but unlike tiled roofs, asphalts have distinct pattern and structure. It has a rugged surface due to its, well, asphalt content. Of course it can be very attractive in numbers. It also looks good in houses with backyards and gardens. Not much else. Today, we see them in places with cold climates. Hot climate will ruin their structure. That being said, it is not that advisable in places with tropical and sub-tropical climate.
Maintenance is different from usual tiled roofs. Asphalt roof is manageable and easy to repair, but being made of inexpensive material, its durability only allows it to last up to thirty years at most. As mentioned, it won’t last in hot, humid climate as the asphalt will morph and could very much ruin the foundation of a roof. This is a roof of choice for cold places. So if you are residing in the Sydney area, which have hot and cold weather, then asphalt roof might not be the most appropriate for your house.
