There are plenty of reasons why you should not put off replacing an old roof. The case of the Metrodome roof collapse in Minnesota is an extreme one, but nonetheless it could have been prevented.
Two years ago the Viking’s football stadium’s roof collapsed after a big storm subjected it to high winds and the weight of two feet of snow. This video that was recorded as it collapsed.
You might think this would be enough to cause severe damage to any roof, and you’re right. But, this roof was particularly vulnerable to serious damage because it was nearly 30 years old. According to reports, eight months prior to the collapse, the roof was inspected by the company who constructed it. The manufacturer urged stadium management to replace it, stating that it had exceeded its service life by 8 years, pointing out holes in the lining, and citing it’s condition as “fair to poor.” Furthermore, it appears the facilities commission had been aware of it’s condition for five years.
Now, it’s unlikely that you’re home or business has a roof anything like the Metrodome’s, but that doesn’t mean the need to replace it when it’s too old is any less dire. If you put off repairing or replacing your roof when it’s exceeded its expected service life, the roof could begin to deteriorate, putting you and your family in danger – especially when big storms come through. So, let’s go over some things to watch out for if your roof is reaching the end of its service life:
- If you are seeing frequent leaks in more than 1 or 2 areas
- If many of the shingles are wavy or fraying at the edges, covered in moss, or missing granules on the face of the shingle
- If the shakes are crumbling or just crunchy and you start to find them on the ground around your house
- If, when you’re in the attic, you can see light showing through the shake roof, dark spots of mold, water staining or the roof sheeting is warped or sagging
- If the siding on your home is decayed or the paint is blistering and peeling
- If your heating/cooling energy bills are excessive, which could be due to poor or lack of ventilation or air flow restriction
Leaks and missing shingles can usually be repaired without having to replace the roof completely. But, if your roof is more than 15 years old and you see one or more of these problems cropping up, it is critical to have a professional inspect it and possibly replace it to ensure your safety and comfort.
