Shingle failure is one of the most common roof problems in America. As such, many think this is a natural part of having a shingle roof. In reality it isn’t, in fact a properly installed and maintained shingle roof can last for decades without a single failure!
The reason why shingle failures occur so often comes down to one thing, someone went too cheap and cut corners. Whether those corners were in the form of cheap labor or materials the end result is the same, the homeowner pays the price both in money and headaches
Cheap Things Are Cheap For A Reason, That Goes For Roofers Too!
While mistakes happen to even the best roof contractors, installation problems are most prevalent among the roof contractors who deeply undercut their competitors on price. The “cheap” roofers, especially those that offer roofs for thousands less than the established roofers.
Material costs are largely the same no matter who the roof contractor is, so the cuts have to come from somewhere and since experienced roof installers command higher salaries, those cuts will usually come in the form of cheaper, inexperienced laborers and that’s where the problems start.
It’s all about the installation, especially the “small things”. Take fastenings for instance, if not fastened properly, shingles blow off easily. If they blow off because they weren’t fastened properly? That voids the warranty and that means you either need to track the roofer down and hope they fix it right this time or you find someone who can, and pay them out of your pocket.
Avoid this by not going with the cheapest option. Good, experienced, professional roof contractors may cost a little more but know shingles must be installed exactly to manufacture specifications otherwise the warranty will be voided.
Unfortunately there are a lot of roof contractors out there who either cut corners or are ignorant of proper installation requirements and the result is homeowners are left with a roof with voided material warranties, oftentimes without the homeowners knowledge and until it’s too late. It happens all the time, especially on roofs that have been air-gunned and not hand-nailed!
How can a poor shingle installation void a warranty?
1.Over-driven nails rip through the shingle and make it very easy for the shingle to be blown off by gusts of wind. Common when nail guns are used.
2.Under-driven nails will hold up the shingle above, preventing it from properly sealing down to the shingle below. This can let dust in which will prevent the sealant from activating, and allows wind to catch the shingle and tear it off.
3.Nails that are driven crooked into the shingle cut into the shingle on one side of the nail, while the other side holds up the shingle above. These two things combined makes for a perfect opportunity for shingles to be blown off by wind.
4. Nails that are too short. Nails must be long enough to penetrate through the shingle and all the way through the sheathing. If the roof decking is thick, nails must penetrate up to 3/4″ into the wood.
5.Too few nails. Each type of shingle requires a certain number of nails to be used per shingle, the average is 4 nails placed evenly.
6.Improper placement of fasteners – Each type of shingle also has a “nail line” where nails are required to be placed to achieve the designed performance. If the nail line is missed, then blow-offs are more likely to occur and are not covered by the manufacturer warranty.
Avoid roof problems by doing your homework and hiring only the best roof contractors with a reputation for quality, not cheapness.
