If you’re living in colder climates then the constant freezing and thawing might affect your roof. You can prevent this by sealing your clay tiles in winters.


What factors affect how long shingle roofs last? 


There are several factors that can drastically affect the lifespans of your roof shingles. Some of those factors are listed below. 

  • Materials used-

    Each kind of shingles have its own set of characteristics and drawbacks which determine its durability and sturdiness. If your roofing materials are of the best quality and are appropriately suited to the kind of weather conditions that your house has to withstand, then your roof shingles will automatically last longer.


  • Quality of workmanship-

    A poor quality of installation workmanship can shorten the lifespan of your roof. If the roofing procedure isn’t done by skilled craftsmen and workers, then the chance of severe roof damage due to improper installation increases several folds.


  • Ventilation-

    Poor ventilation can cause your roof shingles to weaken. This is an important factor, especially in the case of Asphalt roof shingles. Proper ventilation allows built-up heat and moisture to escape without causing any harm to the shingles.


  • Insulation-

    If your roof is poorly insulated, then it will be harder to regulate indoor temperatures. You would need additional appliances such as air coolers to regulate the temperature inside your house and this would in turn increase your energy bills.


  • Exposure to Sun-

    Too much exposure to sunlight can prove to be very harmful. Prolonged hours of exposure to the scorching sun can lead to cracks and degradation of your roof. UV radiations can fasten the process of roof degradation, and thus it is advisable to install roofs that can handle sun rays well.

Signs that your roof needs a replacement: 

If you have an Asphalt roof then, cracked shingles, formation of mineral granules, and curling are signs that your roof needs a replacement. With a Metal Roof, the appearance of widespread rust or discoloration, mold, or water staining should be your cue to get a new roof. For Wood shingles, pest damage, rotting or splitting shingles, and for Slate tile roof, water damage in the attic and cracked shingles are the signs of roof replacement, respectively. If your roof needs repairs after every 2/3 years, then it is more cost-effective for you to invest in a new roof rather than repairing a damaged roof over and over again. 

The most important step to ensure that your roof lasts a long time is to schedule regular maintenance and inspection done by professional contractors. If you can identify the problems early on, then it would be easier to perform repairs and also extend the lifespan of your roof.
