8 Most Common Roof Issues We Come Across

As specialist waterproofing contractors, we’ve seen our fair share of roofing nightmares, from small roof leaks to bad installations, and major damage from external forces. In most cases, these roof problems demand immediate attention to avoid costly replacements down the line. To help you out, we’ve listed some of the most common reasons to call a waterproofing repair service​​

Roof Leaks

By far the most common roof problem faced by homeowners and businesses alike is leaking roofs. It’s often around the rainy season that leaks are identified, and the buckets come out. Roof leaks happen for a number of reasons, but whatever the cause, it’s important to call in a waterproofing contractor as soon as possible to inspect, repair and waterproof your roof as soon as possible to prevent further damage.

Clogged Gutters

When’s the last time you cleaned out your gutters? Months of debris build up can easily block up your roof gutters, causing any rain water to flow over, and resulting in broken gutters, rotting fascia boards, mould, roof rot as well as damage to the inner walls and windows.

Poor or Non-existent Maintenance

When caught early, most roof problems are relatively easy to fix. Neglecting basic roof maintenance checks and repairs, however, could eventually lead to roof damage of some kind which will only get worse the longer it’s left untended.

Tree Damage

Tree limbs that are close to your building or that overhang onto your roof can pose a huge problem if not regularly trimmed back or removed altogether. From branches scratching and wearing down the top layer, to falling branches – trees can definitely cause a lot of damage to your roof.

Incorrect Installation

Choosing fly-by-night waterproofing contractors can cost you more money in the long run. Waterproofing that has not been applied properly remains one of the most common reasons for future damage and complications down the line.

Shrinkage & Blistering

Over time, the roof membrane under tiles or shingles can shrink, causing a host of other issues such as cracking, blistering, ridging, splitting, surface erosion and other shrink-related damage that will need to be repaired​

Pooling Water

If you have a flat roof, pooling water is a sure sign of a drainage problem which can have costly consequences, including major roof leaks, roof material deterioration and a sagging roof. If you spot ponds of water on your roof that doesn’t drain for 48 hours, it’s time to call in the professionals.


Your roof has direct exposure to the elements 24/7, 365 which in itself causes a certain degree of deterioration to your roof over time. Regularly inspecting your roof for damage caused by hail, wildlife, wind and other environmental variables will ensure that you can fix the problem before it gets worse.

Whenever we’re talking about roof damage, we always advise our customers to err on the side of caution. Repairing and waterproofing roofs is not only tricky, but it can also be extremely dangerous. This is why we recommend that you call a professional waterproofing contractor like Connoisseur Roofs to get the job done right.
