    10 signs that it’s time for a roof replacement

    There are many warning signs and symptoms that it’s time to replace your old roof. However, the best way to know for sure is to schedule a consultation with a ModEx roof replacement specialist. We’ll inspect your roof from the inside out, and give you a detailed report on the state of your roof, potential dangers, and even how much longer we expect it to keep performing and passing inspections. Use the button below to schedule a consultation, and look out for these re-roofing warning signs:

    Shingles are like puzzle pieces that come together to make up your roof. And just like a jigsaw puzzle, if the pieces of your roof start to warp or bend, your roof won’t fit together properly. That means there’s spaces for moisture to get in, and for your heat or AC to get out.

    The “grit” in your roof is actually a vital component of the shingles that’s held in place by tar, asphalt, or glue. Over the years, constant exposure to the elements makes the adhesive dries out and becomes brittle. Once that happens, the sticky substance loses its grip, and the grit wears away, leaving a bald spot. That bald spot means your roof is starting to deteriorate and you need to act fast before the damage gets worse.

    This is actually a 2-part problem. First, shingles dry out and become brittle and weak. Then, wind, rain, flying debris, and even tiny critters like squirrels start wearing away the weakened shingles. If the shingles are chalky or wet feeling, you will need a new roof soon.

    A roof is only as good as its seams, and the bigger the home, the more seams it has. The sealed areas around skylights, chimneys, attic vents, and windows can become weakened over time and start to separate, allowing moisture to enter the home and start rotting the wood and corroding metal. Re-seaming the roof is a temporary solution but you can only re-seam so many times before the damage becomes irreversible.

    Dark or light colored streaking occurs when airborne algae begins to grow on your roof shingles. Algae and other airborne lichens love moisture. In fact, they love it so much, they live in it. So that means that if you have algae living on your roof shingles, chances are it’s pretty moist up there. No bueno.

    A rolling stone gathers no moss, and neither should your roof! Moss has very strong roots that can chew through some very tough materials like concrete and tree trunks, so just imagine what it could do to a few inches of tar and plywood. Plus the moisture moss traps underneath can cause rot in your substrate. Not only is moss harmful, it’s also not the most attractive roofing material.

    Water causes moisture, moisture causes rot, rot causes more rot, and before you know it, those minor soft spots you noticed have become a major problem. Cutting out the rot and patching the area works, but softs spots are often indicators of a larger systemic issue that require decisive re-roofing solutions.

    If you go up in the attic of your home during the day and look along the roof line, do you see light leaking in? If so, that may mean that your roof is starting to pull up from the frame of your home. The more light you see, the worse the separation is. Anything more than an inch warrants an inspection from a professional roofer.

    Minnesota homeowners know all about the dangers of excessive snow on the roof. But too little snow on your roof from melting away due to  heat loss is no less dangerous. Not only do melting spots indicate problems with insulation, but the combination of warm and ice-cold surfaces on your roof can cause warping. While the excess moisture can seep inside the surface of your roof and re-freeze, causing internal structural damage. Not only that, but the runoff water from the hot spots can result in ice dams and backflow. If you’re from Minnesota, then you know ice dams are among our worst fears, like going to the Mall of America near Christmas, or the Green Bay Packers.

    You know what? You don’t have to have damage or rot or the danger of further damage to justify a new roof for your home. Sometimes, the best reason to get a new roof is that you want something that looks great. Picking out and designing a new roof for your home is like buying a new car or taking a long family vacation. It’s a major purchase, but in the long run, you’ll be glad you did it.
