You can’t assume that your roof is the same age as your building and it is a good idea to know the exact age. For the most part, a well taken care of roof can last decades providing harsh weather does not cause serious damage. Whether your roof is old or new, it is good practice to start looking after it regularly. Any damage you may find needs to be addressed right away otherwise it can damage the structural integrity of your home. Get to know your roofing material so that you can prepare yourself for how long it will last and learn the best ways to care for the roof you have.
It’s all about the materials
The majority of homes have asphalt or composite shingles which can last up to 20 years. Premium brands can even last as long as 50 years. Fiber cement roofing will last close to 25 years and architectural asphalt and cedar shake lasts about 30 years. For really long lasting roofs, you want metal which can last between 40 and 80 years. And lasting even longer, with a range between 80 and 100 years is slate and tile.
Weather can damage anything
Even the most durable of materials like metal and slate can be damaged by harsh weather. Exposure to certain conditions can gradually wear away anything. Harsh winds can puch shingles up across their edges or pull them off completely. Missing shingles allow those nearby to become more vulnerable to the elements. Strong winds can cause suction and pull materials from the surface depending on the airflow of your home. It can also cause other objects such as trees to come down on the roof, loosening or cracking them.
Hail is the number one cause of damage in terms of weather because it is the equivalent of stones being thrown at your building. The ice balls can dent metal, crack tiles and wear away asphalt shingles. Even though most materials can stand up to small hailstones, it is recommended that you check your roof after any storm.
Most roofing and endure snow and ice but heavy conditions can lead to cracking. When the snow melts, it can seep into the cracks and refreeze once underneath. This expansion causes shingles to shift to shift out of place and can weaken tiles. The sn can even case wear over time because the string UV rays can break down materials with constant exposure.
When it’s time for repairs
It is a good idea to regularly check your roof for signs of aging or damage. Check to see if the shingles have curled at the edges or buckled and look for any cracks or missing pieces. If you have an asphalt roof, damage can be detected if you notice granules in the gutter. Slate and tiles can end up with punctures and when weakened will show surface flaking.
Look for damaged flashing around your chimney, vents and low valleys because rust and dents can allow water to seep through. You also want to check for mold or fungus growth. Wood shake is vulnerable in wetter climates because over time it absorbs water so it can grow mold quickly or start to split. Be sure you check the roof from the inside too by checking the attic for leaks. Use a flashlight to find any stains or wet spots.
If you discover any damage, there is no need to panic because you may not need to replace the whole roof. You need to get the damage looked at right away and assessed by a professional so you can evaluate the repair options. We will thoroughly evaluate your roof and provide a fair estimate of what needs to be done. The most important thing to remember is that regular maintenance and inspection is the key to a long life for your roof.
