While some causes of roof damage are easy to guess – think hail and snowstorms – others are more insidious. Yet, quite often, it is the very fact that these causes go unnoticed that results in them becoming much larger problems later. So how do you know what could be damaging to your roof and what is not? Let’s start with the top three most overlooked causes of roof damage for low-slope roofs.
- Faulty installation. No matter how impact resistant, leak proof, or durable your roofing system is promised to be, no system installed incorrectly can protect your roof properly. And while a lot goes into installing a roof right, for a low-slope roof, the number one installation failure is lack of pitch. Without at least a ¼ inch pitch, water will not drain off of your roof fully, and what you are left with is water buildup – which for a roof spells disaster.
- Little to No Maintenance. While the National Roofing Contractors Association (NRCA) states that the single most important factor (after installation) in the lifespan of your roof is the amount that you maintain it, most people simply don’t do it. Yet when you don’t, debris can dam water, branches, hail, and even wildlife can damage your roof tiles which could then allow water to seep underneath them.
- Freezing and Thawing. It would be nice if a roof didn’t expand and contract. However, with rapid changes in temperature – which can be expected in any state that has a large variance between daytime highs and nighttime lows – a low slope roof will expand and contract along with temperature increases and decreases. And all this expanding and contracting puts strains on all of the seams, bonding membranes, and adjoining components of your roof. So while you can’t prevent movement in your roof, you can have your roof inspected regularly to check any seams, adhesions, and flashings that may be coming loose.
By starting with proper installation – through a licensed and reputable contractor – adhering to a strict maintenance cycle, and including inspection of any seams, adhesions, and flashings on your roof, you can not only go a long way toward preventing both hidden and obvious roof damage, but also enjoy your roof for years to come.
