It is a well-known fact that asphalt shingles are one of the most reasonably priced, durable, and ubiquitous form of roofing material that is available today in many parts of the world. Typically, asphalt shingles could be made from fibreglass or from a mixture of organic materials, like wood scraps, paper, etc. One of the biggest advantages of using asphalt shingles is that it is easy to install because they are flat and they do not need any additional roofing materials; just staples or nails to fix them to the roof frame.

However, shingles do have a tendency to warp in extreme changes in weather, which can cause the covering of the tiles to crack, causing water to accumulate beneath the tile, leading to curling of the edges. This gives the roof an unsightly appearance, which is why installing a metal roof is a much better option. The first item on the agenda is to call in a professional roofing company who have years of experience in all types of roofing materials. They would make a thorough assessment of the condition of the roof and give a quotation on how long and how much it would take and time involved.

Preparing the building site and checking the existing roof and rafters for any structural damage is of extreme importance. Based on this assessment, the repair team have the option of removing the existing roof, damaged tiles, and/or battens; they could also decide to fix a new metal roof over the existing roof. During installation, it is important to ensure that joints in the roof and walls are properly waterproofed to form a weather-resistant barrier. Simultaneously, provisions have to be made to ensure that there is no chance of debris collecting on the roof to prevent accumulated water being drained away.
