When to Replace Your Roof

When to Replace Your Roof

Eventually, each proud owner of a separate house has to choose between accurate repair and total roof replacement Calgary. Surely, it is highly important not to miss the very moment when the advantages of the complete reinstallation outweigh the benefits of small improvements.

The trick is to choose the right time when the problem can be solved with minimal wastes, decrease sequentially developing defects of the supporting structures and preserve the aesthetically acceptable decor. Thus, let us check several signs that clearly demonstrate the need for fast and proper remount.

Curling and/or Missing Sections of the Roof

Missing panels are usually replaced during routine maintenance operations. However, when their number exceeds a certain threshold it is really telling you about upcoming changes in the d├ęcor of your home.

Cracks in Roofing Elements

Note the fact that the point at issue is about a great percentage of cracks caused by prolonged deterioration. Isolated roofing panels damaged because of unlikely severe weather conditions require only partial replacement whereas the whole epidemic of cracks and splits surely demonstrate that your roof has had its day.


Moss grows on those substances that receive too much moisture content and too little sunlight. Slowly but effectively it destroys the panels causing deterioration and corrosion pits, especially on wooden and asphalt roofs. If you have spotted thick layers of moss on the roof, you should seek the advice from a qualified roof contractor with no delay. These are the signs of a serious deterioration. Unfortunately, routine repair is unlikely to solve this problem for a considerably long time.

Missing Asphalt Elements

Heavy rains continuously wash down the elements of the asphalt roofing materials. At some point, the process cannot be stopped by partial replacement. If you have no confidence in the condition of your roof, contact licensed roof contractor in order to obtain a professional estimation of its condition and check the most probable course of actions.

Prolonged Operational Lifetime

You have not changed the roof for more than several decades. A standard metal, clay or synthetic shingle (roofing panel) has an average lifespan of twenty-five years. Older roofing materials may develop serious fatigue of material.
Surely, this does not mean that every twenty-year-old roof requires complete replacement. In fact, some plastic materials can serve for more than fifty years without repair! Nonetheless, a careful house owner should keep an eye on such a construction in order to detect the initial damage.
Sagging Roof

Needless to mention that this is the point of no return. Once you see this, you should understand that you have to install a new roof before the old one becomes too dangerous and counterproductive.

It is also necessary to remember that damage to even minor elements of the roof inevitably turns into a major trouble later. Consequently, the repair costs increase following the scope of work whereas a timely conducted repair may prevent these troubles.
