It's safe to say that a roof is one of the most important structural components of a house. Over the course of years, a roof will deteriorate or become damaged due to wind, hail or other environmental factors. Many homeowners may wonder whether their roof needs to be replaced or repaired. Sometimes, a roof is still in good shape except for a spot or two. Let's go over some of the most common reasons to repair an asphalt roof without removing the the existing one.
Lifted, broken or missing shingles due to heavy weather is one reason to get a repair. This is to prevent water from seeping underneath. In this case, the professional roofer would nail a new shingle into place where the shingle was missing or damaged. It is usually more cost effective to replace a spot or two on a roof than to remove and install an entire roof. Roof flashing which is usually made of galvanized steel may need to repaired due to improper installation or cheap material. This causes the flashing to break or curl up which lets water seep through. Flashing is installed in places where the roof meets a vertical surface such as a chimney, walls, or dormers and are also installed to surround skylights and vents.
Roof leaks in general usually require a repair. There are a number of reasons including the ones just mentioned that cause a leaky roof. An over flooded gutter can cause the roof plywood to rot. Rotted plywood allows water to leak through. Some roofs are not ventilated properly, so the humidity will also lead to the rotting of plywood and fascia board. If you see damaged parts of your roof or have a leak, the first thing you should do is contact a professional roofer to inspect the roof and determine if your roof needs to be replaced or repaired. Sometimes a simple repair can extend the longevity of your roof and save you money.
