ReplacementIn general, our roofers at McDonald & Wetle\u00a0can work with you to determine whether your commercial space is in need of extensive repairs or a replacement. Often, it comes down to cost\u00a0\u2014 if the estimated cost of repairs exceeds that of a commercial roof replacement, for example, it typically makes more sense to get your roof replaced completely, either with a new roofing type or the same type.Factors Determining A Commercial Roof Replacement1. Water DamageWater is the enemy of commercial roofs, and keeping it out can often be challenging. If you’re having problems with water infiltration, it may be a sign that your roof needs extensive repairs or may need to be replaced in certain spots.Usually, a thorough assessment is needed to determine the extent of water damage to a commercial roof. Keep in mind that while the roof membrane may appear to be in good condition, the material underneath may be damaged caused by water trapped beneath the roof’s surface.2.Extensive Membrane DamageThe primary purpose of a roof membrane is to move water off the roof. Commonly used in commercial applications, they\u2019re usually made of rubber, thermoplastic, or modified asphalt. When this membrane has become severely split or experienced severe uplift thanks to strong Portland winds, it may be time for a roof replacement. Corners, seams, parapets, and other common problem areas should also be checked for damage.3.MoldIf there is mold growth on or under your roof, this is a sign it should be replaced. Mold can form when there are undetected roof leaks, and this can also cause an unpleasant smell in interior spaces.4.Missing Shingles or HolesMissing shingles provide an easy entrance for rainwater into the interior space of your business. Sometimes this can be fixed with a commercial roof repair, but in other cases, if the damage is extensive, replacement may be needed. At McDonald & Wetle, we work closely with your business to help determine the best solution for your situation.5.Lack of Roof MaintenanceIf a commercial roof isn’t maintained or inspected regularly, such as every two years, it’s possible this can lead to an eventual need for replacement.
