Most roofing companies use high-quality roofing materials and pay attention to details and, as a result, do quality work that lasts for decades.
While this is the case, some contractors try to cut corners to save time or money. They rush through the process ending up with a poorly done roof.
If this is the first time installing the roof, you might not be aware of whether the roof was installed correctly or not. To help you out, here is a guide on how to tell if your roof was installed correctly:
How many layers of shingles does the roof have?
A roof with three or more layers of shingles adds unnecessary weight to the house. If your house doesn’t have a strong foundation, chances are high the house will crumble soon. If the house already has two layers of shingles, reputable and experienced contractors usually remove the old shingles before installing the new ones.
So if you inspect the roof and you find more than three layers, the roof wasn’t correctly done. You will be in danger of the house crumbling on you. To protect yourself and the house, you should hire a contractor first to remove the extra layer and properly install the new shingles.
Inspect the drip edge flashing
The drip edge is the flashing material that contractors must install at the edges of the roof to prevent water damage, basement flooding, stains, and soil erosion. The drip edge also protects your home from pest infestation that often starts in the attic.
If your contractor did a good job, if your home has a shingle roof, the gables and eaves should have a drip edge.
As a homeowner, you will rarely know whether your house has a drip edge but you can look out for signs. If you have noticed your house leaking or having moisture issues, ask a qualified technician to look into it.
How does the roof look?
When you look at the roof, how does it look? Is it symmetrical? A properly installed roof should be uniform. The shingles and shakes should be evenly applied and properly aligned at all times.
If you do a visual inspection of the roof and you notice sagging roof lines, shingles of a different color, and some sections of the roof being different from the rest, your roof wasn’t correctly installed, and it’s time to hire an expert to fix it.
Look at how the nails have been nailed.
The nailing technique used by the contractor can also guide you on the quality of roofing. In a properly done roof, the nails should be positioned at the right locations. The nails also shouldn’t be rusted.
Telltale signs your roof has improper nailing include:
Overdriven nails: These are nails that have been driven too deep into the shingles. Overdriven nails tend to be sunk or buried into the roofing material, giving it a cheap, ugly look.
Nails in the wrong location: Nails will be located in the wrong place when the contractor is inexperienced or wasn’t keen when doing the work. When the roof is properly done, the nails should be 2.5 cm above the cut-out and 2.5 cm from the edges.
Rusted nails: Roofing technicians that aren’t looking to cut corners use stainless steel, galvanized steel, or any other corrosion-resistant nails, so if you do a visual inspection and notice rusted nails, chances are the roof isn’t properly installed.
How are the shingles installed?
In a properly installed roof, the shingles should be installed with precision. The shingles should have an overhang that is at least ¼ inch. The purpose of the overhang is to prevent the wood from rotting hence giving them a long life.
The shingles should also be properly aligned, which not only ensures the roof is beautiful to look at, but also free of water leaks.
Unless the roof is old or has been damaged by severe weather, a well-installed roof should not leak, so if you see any leakages, your roofing contractors Cos Cob CT didn’t do a good job. The roof also won’t have been properly installed if you see dark stains on the roof.
To prevent further damage, hire a contractor to inspect the issue and fix it.
