Do You Need to Worry About Your Roof Shrinking?

Do You Need to Worry About Your Roof Shrinking?

If you’re unfamiliar with this roofing problem, then you might think that it means your roof will start to shrink over the years of service it gives you.

Although roof repairs, preventative maintenance, and total replacement are perfectly normal, most homeowners are probably unaware that their roof can shrink as well. Here is some more information about what that is so you can make the best decision for the safety and integrity of your home’s exterior.

What Is it?

If you’re unfamiliar with this roofing problem, then you might think that it means your roof will start to shrink over the years of service it gives you. However, this is a misconception. Instead, it has to do with the membranes that help shield your roof in all kinds of weather. These membranes also help protect your shingles from changing temperatures and impact damage, whether from low-hanging tree branches or even hailstorms. As these protective membranes deteriorate, however, it means that cracks and leaks can start to form. On top of that, any problems or issues that already exist will only get worse.

Possible Causes

Naturally, once you have determined there is something wrong with your roof, you would want to know what could be causing it. There could be many factors affecting the structural integrity of your home’s roof, such as the presence of water damage, mold, or invasive pests. Even so, here are some of the most common causes of roof shrinkage:


  1. Poorly made or applied membrane: The membranes could be poorly made or misapplied. Without sufficient quality assurance testing, the membrane won’t last as long as others that are applied correctly and manufactured according to proper procedures.
  2. Other roofing materials: Even if the membrane itself is well-made, problems could occur once it is applied to the roof. The membranes need oil to ensure flexibility, and if the oil isn’t mixed just the right way, then this won’t happen.
  3. Roof design: The size and design of the roof could pose problems as well. Larger roofs are more prone to this issue, which means that even more of the roof will be damaged or left unprotected than with a smaller roof.
  4. Venting issues: Venting and ventilation are essential for maintaining your roof. Venting will release trapped moisture, which prevents damage to the roofing membranes. However, venting is much more common on the roofs of commercial buildings than on homes.
