While a new roof structure may last anywhere from twenty to thirty years before needing to be replaced, it is not maintenance-free and requires occasional repair work. There are five basic repairs which will be needed at some point no matter how well-constructed your original roof was.
The shingles that make up the outer surface of the roof bear the direct attack of weather and the damage it causes. Despite hail, rain, high winds, snow, and ice, the shingles on your roof must be rugged enough to withstand it all while maintaining their integrity over the years. Regardless of the quality of a shingle, repairs must be occasionally made to replace broken sections. Usually it works out to be less costly to replace the entire roof covering if more than one third of the shingles have been damaged.
The hardest part of fixing a leaky roof is finding the place where the water is entering. It can be difficult for even a professional contractor to hunt them down. It can also be very expensive to fix a leak. It may involve tearing out a section of the roof structure or even part of a wall. Time is critical since the situation can only get worse and the longer the leak exists the greater the possibility of further damage by rot or mold.
Even without leaks, moisture can attack your roof from within. With heat and humidity, moisture can be trapped under your roof and create conditions ripe for mold. Excess humidity can also make the wood swell and buckle at the joints. Adding ventilation points can help improve air flow and structural health to your home.
The most common area of leakage tends to center around the flashing at the chimney, vent ports, and joints between roof sections. While re-flashing your roof can be time consuming and expensive, this critical part of water protection, when done right, can then last for decades with no further problems.
The greatest damage to your gutters is caused by leaves, dirt, and other debris building up in the gutters and not being cleaned out. This material can get very heavy on it’s own. Rain will weigh it down more as it is soaked up into the detritus. The guttering can bend, warp, or even pull loose completely. A full gutter cannot direct water away from your walls as well and can expose them to more direct water flow.
