Your best first step is to get it inspected by a reputable roofing company to find out if a partial or full roof replacement is required. If the last time you reroofed your home was 20 years ago, it’s definitely time to have your roof inspected and take a look at what else is on the market today. In addition to some of the more traditional shingles (asphalt, slate, shakes), there are also highly attractive metal roofs that give the appearance of other materials, and architectural shingles that are head and shoulders above traditional asphalt in terms of looks and performance. If you currently have asphalt shingles on your roof, you may have choice in how you proceed with the new shingles, depending on what’s already up there. You can have up to two layers of asphalt shingles on your roof. Layering one layer on top of the other is a good way to save some money on installation costs. Unfortunately, you can only do this once, and it shingles adhere better directly to the roof than to another layer of shingles, so if you live in an area with high winds, you may be better off stripping. Before you let the roofers up onto your roof, you should understand what the process is going to entail. Make sure you find out if they’re stripping or layering, whether or not there will be a height difference if you are only partially reroofing, and that they are taking care to flash and trim the appropriate areas.
Replacing a roof is a major investment; don’t leave anything up to chance. Stay as informed as possible and weigh each of your decisions carefully before making any choices. In the end, your new roof should last you at least 20 to 30 years, so make sure you’re happy with the results in the end. For information checkout this online article>>
