Your building's roof is a critical structural, safety, and aesthetic component. Many small roofing issues may initially appear to be little more than cosmetic problems, but they can quickly cause significant amounts of damage. Water infiltration tends to be particularly insidious, as seemingly small amounts of damage often hide much deeper roofing problems.
While the best approach is always to maintain and repair your roof to maximize its lifespan, replacement is sometimes unavoidable. Below you'll find three ways that water can damage your roof severely enough to require replacement.
1. Consistent Leakage
If you notice leaks early, you can often locate the problem's source and conduct spot repairs. Unfortunately, leaks do not always make themselves apparent. Especially in large commercial structures, it is typical for small leaks to drip into unoccupied or infrequently-used utility areas. When these leaks go unnoticed for long enough, they can lead to severe water damage issues.
Since many commercial buildings use flat membrane roofs, leaks can also cause the roof to fail much more quickly. Once water infiltrates below the waterproof membrane, it can begin to damage the underlying roof decking. This moisture can cause significant structural damage that will eventually force you to replace your entire roof.
Ponding is a significantly less subtle problem than interior leaks. Flat commercial roofing still uses a small grade to slope the roof towards drains or gutters, allowing water to flow from the roofing surface. Drainage problems or issues with the pitch of the roof can compromise this design, however. When this happens, water tends to pool in large puddles or "ponds."
Ponding on a commercial roof isn't always a fatal problem, but significant ponding often means that a full roof replacement is in your near future. When left alone, roofing ponds can give water a chance to infiltrate into small gaps, leading to interior damage or further issues with the roof membrane. If you have multiple ponds forming on your roof, it's probably time to consider a replacement.
3. Poor Drainage
Poor drainage tends to be an issue with the original design or installation of your roof. If water cannot adequately drain from the surface, it may lead to ponding, leaks, or water finding its way into areas that lack full waterproofing. Drainage issues can lead to numerous expensive repairs, especially if you treat the symptoms without discovering the underlying cause.
If you have identified one or more severe drainage issues on your roof, then replacement may be the most cost-effective option. An experienced commercial roofing contractor can install a new roof with proper drainage design, saving you a significant amount of money on repairs and maintenance over the long term.
