Average Roof Lifespan
Different roof types have different lifetimes. We’ll begin by listing our average roof lifespans, based on the type of roofing material.
In normal conditions, 3-tab asphalt roof shingles should last between 15 and 20 years before they need to be replaced. Architectural asphalt shingle roofing is more resistant to the elements because of its design. They can last for up to 10 times longer than 3-tab asphalt roofing shingles.
Clay/Cement Tile Roof
Concrete/clay tile roofing is the most durable option for roofing. The tiles are not only very durable but also extremely heavy. They are installed on top of extra-sturdy roofing reinforcements, providing even greater protection for your home.
Tile roofing is very durable and can last 50 to 100 years.
Slate roofs are the most durable. It will usually last for 100 years or more.
Wooden shingles last between 25-30 years. They do require some maintenance which can reduce their life expectancy.
If leaves and moss grow on the roof, they can trap moisture, which encourages decay. If you do the right maintenance, your wood shingle roof can last 50 years.
Wood roofing can also be damaged by fire. It is therefore illegal to place wood roofing in certain areas as it could easily catch fire.
Wood shakes are more durable than shingles because they are thicker than shingles. These roofs are expected to last between 35-40 years.
Maintenance is also important. The life expectancy of a wood shake roof is determined by how well it is maintained.
Another option for resilient roofing is metal roofing. Metal roofing materials such as steel and aluminum should last for 50 years before they need to be replaced. Copper and zinc both have a 100-year lifespan.
Other factors that affect roof life span
Your roof’s lifespan is not only determined by its material. Weather and maintenance are also important factors. Certain weather conditions can cause wood shingles to crack or mold more easily. Sealant erosion can happen to even the most resilient metal roofs.
Asphalt shingles can also be easily damaged by high winds because they are extremely light. Windy areas that have a lot of foliage may also cause damage to the roof.
If this damage is not addressed quickly, it can rapidly get worse. Small cracks can allow moisture to seep under roofing materials. It expands and contracts as temperature changes change, which causes the crack to grow.
Annual roof inspections are important for extending the life of your roof regardless of its material.
Roof damage signs that can reduce the life expectancy of your roof
Untreated roof damage can quickly worsen, as stated. These common roof damage will reduce the lifespan of your roof if it isn’t fixed.
Holes and Leaks
Roof damage is evident when you can see the sun shining through holes. These signs indicate that your roof needs to be replaced soon.
Even though the cracks and holes are smaller, they will allow moisture to enter. As we have already mentioned, these cracks and holes can quickly become worse.
You should have your roof checked if you see sunlight through your ceiling, or if it rains in the attic.
Moisture and water stain/damage
Additional signs of leakage include excessive moisture and water stains/damage to the roof decking or ceiling. The moisture that is leaking into your attic can seep into the insulation. You might want to inspect this area, as well. Puddles might also be found in your attic.
A leaky ceiling is one that has yellowish or brownish stains. This is also true for walls with yellowish or brown streaks. Rainwater carrying dirt and other debris can cause this discoloration.
A leaky roof is a sign that your ceiling is sagging. If you see these signs, it is important to have your roof repaired.
Exterior Roof Damage
Roof damage can also be visible from the exterior. Cracked, missing, damaged, or otherwise damaged roof shingles are the most obvious.
You should also inspect any spots on your roof that look unusual. Roofs should have a neat, uniform appearance.
One spot that looks unusual may be a sign of a poor patch job done by an inexperienced roofer. Bad patch jobs can cause more damage than good so please call it in.
You can inspect the ground and gutters around your home if you are unable to see the roof’s exterior. You’ll find pieces of your shingles in the gutters or on the ground if they are damaged. These areas should be checked for debris that looks similar to your chimney/flashing.
This damage can expose your roof to the elements and make it vulnerable to further damage.
