Four Common Roofing Mistakes To Avoid




Toronto is a beautiful city filled with history and culture. With a history stretching hundreds of years, Toronto has many buildings in need of renovation or repair. It’s tempting for many homeowners to try to fix our houses all by ourselves. Watching home renovation shows on television gives us the impression that such work is easily handled and experts are simply unnecessary middlemen getting in the way of an easily fixed problem.

The reality of roof renovation; however, is that you will almost always need the help of experts like Professional Roofers in Toronto to get a professional level of quality. When it comes to something as important as your roof, mistakes are not only inevitable in a DIY job, but they could be incredibly costly in the long run, leading to significant household damage. Professional services for these issues exist for a reason, but ensure you choose a qualified, reputable roofer like Professionalroofers.com when you have your roof renovated – or you could end up in exactly the same boat. Here are just a few of the biggest mistakes to avoid when you need to repair a damaged roof.

Installing Shingles Incorrectly

A major source of headache for repairmen is caused by shingles that were installed incorrectly. Oftentimes DIY enthusiasts will place the starter shingles in the incorrect position, which allows water to invade the sheathing around the shingle cutouts. A major factor contributing to this problem is placing shingles on a low slope roof. The poor angling makes it difficult for shingles to function properly and allow water to shed off of them. Shingles are not intrinsically waterproof and will not serve their purpose if the roof’s slope is below 2:12.

Poor Nailing

One of the biggest roofing mistakes you can make is with improper nailing techniques. Shingles are generally made of fiberglass with a layer of asphalt applied to the top of the fiberglass. When you drive a nail through a shingle it literally tears the shingle and if you the drive the nail in with too much force, the shingle will become compromised. This is why it’s important to simply throw away any damaged shingles instead of reusing them – shingles are not meant to withstand extreme force.

Poor Attic Ventilation

In America, 9 out of 10 attics are not properly ventilated. This creates a major health problem for many children who are prone to catching asthma. In fact, 58% of all asthma cases are related to improperly ventilated roofs. Hot, humid roofs provide the perfect backdrop for infectious bacteria to grow rapidly and can therefore lead to other health problems as well. There are also financial issues associated with poor attic ventilation leading to higher air conditioning and heating bills and damage to shingles as well.

Use Of Asphalt Cement In Repairs

A major misconception is that because shingles are covered in a layer of asphalt, it is ideal to use asphalt to repair damaged roofs. This results in an improper mix of materials and further promotes damage to the roof. Damaged shingles should always be replaced with new shingles.
