You've probably heard horror stories about shingles that fail just a few years after installation and the fight homeowners have had to go through to get compensation from the manufacturer. However, if your new shingles are starting to show signs of wear, it might not be the manufacturer's fault. These situations are known to cause premature failure all on their own.
Even if your roof is nearly new and installed perfectly, it can still fail if the roof structure is failing. Sagging joists can cause water to pool in low areas, and that excess moisture is seriously bad for your shingles. This is a tough situation as repairing the joist without pulling up your entire roof is a tricky situation. In some cases, you might just have to get additional repairs to that section of roof until it is time to replace the entire section.
One option you may have, depending on the structure of your home, is to add a jock to the sagging rafters to hold them in place until they can be repaired. Whether or not this will work for you depends greatly on whether or not you can get direct access to the rafters and whether or not there is somewhere you can place the jack on the lower level that can bear the additional load. While this is a job you can do yourself, you might want to get a contractor involved to ensure you don't end up doing additional structural damage to your home.
There is going to be a common theme with all these issues, and that is moisture staying on your roof too long and essentially causing your shingles to rot. Sagging joists are one way to may a low spot for water to pool, but you still need the water to evaporate. While having good tree coverage of your roof can save you money by reducing the amount of heat your home absorbs in the summer, too much coverage can lead to issues by way of shingles that are never able to dry properly.
In some ways, trees can be a double threat as the debris can quickly start to collect on the roof if you don't keep up on your maintenance, giving mold and mildew an even easier foothold on your roof. Fortunately, you don't need to cut down all your trees to solve this problem. Thinning the canopy a bit so your roof gets some sunlight, even if it is only in early morning or late evening will allow your roof to dry properly without loosing the benefits of the shade. Cleaning your gutters regularly and doing semi-annual visual inspections of the roof will ensure you are aware if leaf litter becomes a danger.
Poor Attic Airflow
Your roof has two sides, and most people only think of the one that faces the outside. After all, the surface of the shingles is the only part that gets wet, so that's the only part that needs to dry, right? Unfortunately, this isn't quite true. Getting too much water under the shingles is a serious issue, but even a healthy roof will get a little moisture underneath that top layer. That moisture needs to dry as well to avoid rotting not only your shingles but also the support structure of your roof.
This means having good attic ventilation. It might be tempting to try and seal this area off in order to try and save on HVAC costs, but you really need to let air move through the space to keep your roof happy and healthy.
Sometimes, the reason your roof is failing is more concrete. Age, weather, or debris all can cause your roof to fail. However, if you are having trouble and these items aren't a factor, check the things listed in this article to see if they could be the cause.

I spent weeks researching metal and shingle roofing to try to figure out what would be the best material to use on my home. I weighed the costs, the length of life, the amount of maintenance required and how well each type would hold up to high winds and strong storms. After compiling all of the information that I needed to make an educated decision about the roofing for my home, I created a blog. This blog is meant to help other homeowners decide which roofing material would be best for their homes now and many years into the future.
