Not all roofs are created equally, and neither are the roofers. Since a roof is your home or commercial buildings first line of defence against the elements, our bet is that you’re going to want to have it built right. And as it turns out, everyone needs (and deserves) a roof that can keep them and their assets safe. Unfortunately, because roofing contractors are so in-demand, many people market themselves as professional roofers when they lack the qualifications and experience to do so. While there are many great roofing companies to choose from, not all roofing contractors are reliable nor reputable. To ensure your roofing in Burnaby is carried out with quality craftsmanship and precision, here are some ways you can identify poor roofing work:

Mismatched Roofing Shingles

For a quick visual assessment, take a look at the shingles laid on a roof. While many roofing contractors use multiple suppliers, some will choose to mix different products into one job. This creates a messy, structurally unsound roof. When speaking with roofing companies, select one that prioritizes consistency and uses reputable suppliers.

Incorrect Use of Roofing Nails

While there are various types of roofing nails, it is highly recommended to use Hot Dipped Galvanized roofing nails to help protect against rust corrosion. Certain asphalt shingle products and the roof pitch will determine how many nails are required to be installed per shingle. If the manufacturer specifications are not followed, warranties can be voided, insurance coverage can be obsolete, and many more issues can potentially ensue. It doesn’t hurt to ask your contractor to show you what the manufacturer recommends. This is a little test to see how knowledgeable your contractor is.

Improper Shingle Overhang

While the best overhang varies roof to roof, shingles should typically be placed with a 4 to 10cm overhang. Anything less causes inefficient water drainage, and anything more increases the risk of the shingles lifting and blowing away during storms. Only roofing companies that can assess the best level of overhang and abide by the material’s manufacturing guidelines should be installing shingles on your roof.

Lack of Attic Ventilation

An underqualified roofing contractor may neglect your attic. A roofing system is made up of several subsystems, the attic being a highly important one. When an attic is not properly ventilated, moisture and heat can cause premature wear and tear on your roofing system. Not to mention it puts your entire building structure at risk. From damaged insulation and wood rot to wall staining and increased energy bills, work with roofing companies that know the importance of attic ventilation. Make sure to review this before hiring a roofing contractor!

Incorrect Underlayment Installation

Underlayment is the layer of your roof that acts as an insurance policy for your decking against water damage. It comes in a variety of materials, the most popular being asphaltic peel and stick membrane, and/or synthetic to provide either a water-resistant or fully waterproof barrier. Depending on the climate in your area, your roofing contractor should choose the underlayment that will best suit your roof. Hint: Canadian weather typically calls for a waterproof underlay at the bottom 3ft of your roof and in the valleys to protect against ice and water damming.

Poor Roof Slope Assessment

Different roofs come with different slopes. And you need roofing materials that are compatible with the angles of your roofing structure. If this step is incorrectly assessed, your roof becomes much more susceptible to leaks.

Sagging Gutters

Gutters are an integral part of your roof’s drainage system. An improperly installed gutter can cause water to overflow and damage your roof. Furthermore, if a gutter isn’t set at the right pitch, the water will remain stagnant instead of flowing towards the downspouts. If they are placed too low, water can flow backwards towards your roofing system. Lastly, if the gutters sag, the weight from the water and debris can force the gutter to be pulled from the fascia. This could expose the roofs outer edges, creating an entry point for water, insects, and critters.

Not Accounting for Ice Dams

The thaw and refreeze process that happens in the winter can lead to water settling under the edges of your roof. To combat this, there are a couple precautionary measures your professional roofer can take. One, there needs to be the correct amount of insulation. Two, your roofer could potentially add an extra layer of underlayment (typically an asphaltic peel and stick membrane).
