If your roof looks like it needs replacement but it's during the rainy season and you're concerned about water damage, or if you don't want to invest in having the old roof removed and hauled away just so it can take up space in a landfill for approximately the rest of forever, you may wish to consider having another layer installed over the top of your current roof. This process of leaving your original roof in place and simply installing another system over the top is called re-covering. Here are three signs that re-covering is what your roof needs.

1. The damage isn't localized

Localized damage is an ideal candidate for patching-type repairs that involve just the affected portion. In a situation where your roof is leaking because a branch fell on it during a storm and compromised its watertightness in a couple of places, you probably just need repairs. But if the roof has begun to fail in a variety of places, whether from age or from severe damage, you may need more thorough measures.

2. You're considering increased insulation

If your building has a deficit of insulation (for example, if only the minimum amount of insulation was installed with the last roof and you'd prefer more) or even if you're just wanting to make the building more eco-friendly by increasing insulation and thus reducing heat loss, re-covering can help. It allows the current roof to remain in place under the new roof, where it's able to act as an added layer of insulation without costing any extra money for installation. The caveat is that if the current insulation is wet and/or there are problems with the roof deck (such as rot from water damage), you shouldn't leave it in place; mold and mildew problems could develop.

3. Your roof hasn't already been re-covered

Generally speaking, it's not a good idea to just keep building up more and more layers of roof. So after one re-covering, you should plan on having a total replacement next time the roof fails. Of course, you can slow the progress of deterioration by using roof coatings (especially cool roof coatings, which minimize heat damage to the roof) and staying on top of maintenance. But in general, it's best to consider re-covering only if the roof hasn't been re-covered already.

These are three signs that re-covering is right for your commercial roof right now. If your roof doesn't meet these criteria, you may be looking at simple repairs or potentially an entire roof replacement. For more information, contact a business such as Kerrigan Roofing & Restoration.
