How long your new roof will last is something that depends not only on the quality of the roof that you install, but also the experience and workmanship of the residential roofing contractor who installs it. It is, therefore, important for you to hire a qualified roofer who will not make rookie and costly mistakes. In this post, we discuss some of the most common roofing mistakes whose avoidance helps you get the maximum out of our new roof.
1. Improper Slope
If the materials you choose do not match the slope of the roof, it may lead to water penetration. For example, if one is installing wood, asphalt or tile shingles & shakes, it is recommended to have a minimum slope of four units rise per twelve units of run.
2. Ventilation Problems
At the time of laying down shingles, it is necessary to allow ceilings or attics to vent. Failing to do so can lead to build up of moisture leading to the premature weakening of the shingle material.
3. Layers of Shingles
Many municipalities require old asphalt to be removed before installing the new one. Not adhering to this rule is illegal. Whether your municipality allows it or not, it is highly recommended that old shingles be removed before new ones are installed as the additional weight harms your roof structure and walls. Removing old shingles also allows your residential roofing contractor to inspect, and if need be, repair fragile areas.
4. Improper use of Nails
If nailed incorrectly, or insufficiently, shingles can slip down causing injury to bystanders. A minimum of four nails per shingle is what we recommend. If the roof has a steep gradient then the minimum number of nails used should be even more, preferably six. Make sure that the nails aren’t driven into or above the self-sealing strip.
5. Failing to Plan for Ice Dams.
For those who live in cold climates, it is common to experience ice dams that form along the roofline. If the roof isn’t insulated enough, these ice dams force water down the shingles. To prevent this, it is necessary to install an under layer in the roof to act as an additional layer and protect against the melting ice water.
Conclusion
Most roofing mistakes result from inexperienced do-it-yourselfers who have little or no prior roofing experience. The same is true for inexperienced or first-time roofing contractors touting cheap services. You must, therefore, check the roofing contractor’s experience, and if possible, check with their past and current clients about the quality of the contractor’s services.
