3 Reasons Why You Should Repair Your Shed Roofing Early and Often

For many people, sheds are some of their most prized side projects that hold nostalgia aside from warmth and shelter. 

Unfortunately, however, sheds can succumb to the elements quite easily because it lacks many of the foundational facets of a traditional home.

But when the time comes to address glaring issues with your shed—i.g. sagging, leaks, etc.—it’s crucial you are well-equipped to handle the many potential problems that can come your way.

Here are some reasons to repair your shed roof to best prepare for the splintering winters of the future.


This is a problem exhibited by many sheds with wooden structures. However, sagging is also seen with plywood shed roofs, too. After this process starts, internal rot typically occurs within mere months. As a result, sagging roofs tend to imply there is a leak somewhere in the roofing.

At this point, if your shed is exhibiting these symptoms, then you will likely have to either replace the roof entirely or buy a new shed. If this problem is relative to your situation, then this could be a signal there is something aloof in terms of the wider picture which could come back to impair future repairs.


This is probably the most common repair issue with most shed roofs. And it should not go ignored. Unfortunately, many shed owners will put off this issue or ignore it entirely only to attempt a repair on their own before it’s too late. If you identify a leak in the early phase, it is good to address it immediately because one small leak can easily turn into a larger one in the near future.

For example, moisture buildup can increase the chance of mold growth in your shed; and if you spend copious amounts of time in it, then you could experience many irritating symptoms to your eyes, nose, lungs, skin and more. In addition to this, your garden tools and other machinery can be recipients of rust. Leaks coming through the roof of your shed can also decrease the overall life expectancy of your shed—in spite of how well it is built beforehand. The main reason for this is due moisture build-up which in-turn can rot the wood from the inside out. In addition, roof leaks can happen through the previously mentioned sagging roof dilemma, tears in roofing felt, or cracked shingles. And while it’s better to replace a sagging roof altogether, leaks can at least be addressed quickly, thereby curtailing future problems.

Exposed timber

As hinted at previously, moisture build-up can subsequently lead to mold and ultimately the slow deterioration of a shed’s roofing. And as with many ways a roof can be left vulnerable, exposed timber is another way moisture and air can get inside your shed which catalyzes this deterioration process.

Once moisture build-up occurs, a damp sort of mold variant can build-up in the interior, which then quickly propagates and decreases your she’d overall life expectancy. And as we have already stated, these types of deteriorative processes can cause leaks in your shed, too.

There you have it! These are the three most salient reasons to repair your shed’s roof early and often.
