It’s easy to assume that you don’t have to worry about damage because your roof is in good shape. But every type of building has its vulnerabilities – even the most solid buildings eventually deteriorate from climate change and nearby vegetation.

No matter how excellent of a job your contractor did, with commercial roofs being so exposed, you can’t afford any negligence when maintaining their structural integrity! Here are some causes behind your commercial roof’s destruction:


High winds from storms can destroy your business’s exterior. Roofs may buckle under pressure while they try their best to hold back nature’s fury before eventually giving way completely. During the winter, moisture gets locked in and then freezes. This expansion can cause quite a bit of damage to shingles and the roof below.

Hailstorms are the worst. They’ll break up your shingles and tear them right off, even with just one hit! And if you’re unlucky enough to experience hurricane season? Well, don’t bet on it – those things will eat away at any roof until there’s nothing left but siding or gutters.

Improper Installation

Roof repairs are often needed because of improper installation. Your original roofing contractor may have used poor, or no roof sealants at all didn’t fasten their work correctly or worse. Due to this, moisture can get through, which leads to leaks in your building’s structure and contributes to deterioration.

One common reason people need roofs fixed is when an improper installation. It might seem like taking shortcuts for faster turnaround times would be helpful, but that often comes without fully considering how things will turn out.

Standing Water

Standing water on your roof can be due to clogged gutters or poor design. In some cases, it is a result of not considering how steep each building’s slope might be. However, this should only occur if you don’t address the issue immediately! Contact an excellent commercial roofing contractor in Allentown, PA, and get it fixed as soon as possible.

If left untreated for too long-standing water will cause damage which may lead in turn toward leaks – if you notice a leak, be sure to get it fixed today before any more bad things happen (like mold growth)!

Penetration and Leak Issues

New penetrations can be made on your commercial roof, even during maintenance checks. Unfortunately, these scrapes and cuts can cause leaks, voiding the warranty and expensive repair bills down the line!

Keep an eye out when any major repairs are being carried out to do minor damage from unexpected sources. For example, rainwater seeps into cracks that aren’t appropriately sealed due to incorrect installation.
