Most homeowners think about replacing their roofs when they spot a leak in their ceilings. However, those leaks can result from one of various issues. Therefore, you need to review other factors as well. For example, you should look at the age of your roof.
The Average Lifespan of Most Roofs
Most roofing experts concur that a roof will last 20 to 25 years. You also have to find out if the old roof was removed and how many layers of shingles are on the house. Also, does your home receive enough ventilation? If your present roof was installed over one or more layers of shingles and is over twenty years old, you probably need to get a new roof.
Also, shingles that curl or buckle are another obvious clue that you probably need a new roof. Review the slopes of your house that receive direct sunlight: if you notice the shingles are either losing granules or are curling, it typically means that the shingles need replacement. If this is happening the roof may also be defective. Contact Kent roofers to see what can be done about the problem.
Check the Roof’s Valleys
In addition, if your roof shingles are missing or falling apart, it’s a sure sign that a new roof is required. Valleys, or the lower parts of your roof, are one of the most important areas. Rain and snow flow through the valleys and into the guttering. If the valley is compromised, your roof will be vulnerable to leaks.
You should also look at the chimney flashing. If the flashing displays tar or roof cement, it may need replacement. Look at installing a water-tight fitting, such as a metal flashing system. You also should look inside the gutters to see if they are loaded with shingle granules. Roofs lose more granules toward the ends of their lives. Darker colours on parts of a roof signal that the granules have faded or worn away.
