Roofing problems can be caused by several factors, including poor ventilation, inadequate insulation, or other structural problems. If you have a roof that is too weak it’s time to call in an expert. Hiring a contractor with years of experience will help you save money in the long run.

6 Common Roofing Mistakes

If you’re going it alone or want to evaluate a contractor’s work, here are the things to focus on.

1. Shingles Not Aligned or Joined

Shingles must fit into a line, the majority of DIY guys who build the roof get it wrong. Start by placing shingles alongside the eaves, leaving no space, as water will pervade the sheathing underneath the shingles.

2. Roof Flashing Not Properly Secured

Flashing protects the roof and the house’s walls from the penetration of water. Roof valleys tend to leak a lot due to the large volumes of runoff water they handle. To avoid problems, flashing needs to be properly secured and then sealed, especially around chimneys, vents, and valleys.

3. Mismatching Shingles

Shingles made of asphalt come in many colors. All of your home’s shingles should be the same type and hue. It will raise the curb appeal and offer a seamless look. If a company has discontinued your home’s roof shingle, that generally not a good sign.

4. Inadequate Attic Ventilation

It’s important that air doesn’t get trapped while laying attics and shingles. Over time it results in moisture, which weakens the shingle material.

During the Summer months, the roof temperature increases. Reputable roofers such as City Seamless Roofing inspect the attic might recommend adding insulation such as polyether foam. It helps ensure a steady attic temperature that results in increased shingle life span and energy efficiency.

5. Improper Roof Sloping 

It might be too late to change this now, but improper slopping can make for a less-than-ideal roof. If the slope is too little, you may have to select a stronger material for that portion of your home’s roof. Flat roofs, like you find on top of many commercial buildings, require a completely different roof solution than most residential properties.

6. Nailing the Roof Poorly.

Experts know the right type of nails to use for any job. They also know the proper number to use. Too few nails and shingles can easily come loose and cause major problems. The steeper the grade means the higher number of nails needed. If you are using any self-sealing strips in a portion of your roof, make sure not to nail through them.
