The roof is a building structure that can too often be perceived as an afterthought. Think about it; the roof is the building’s first protective layer against such adverse weather as rain, wind and snow.
In fact, you might not start paying serious attention to your roof until it starts leaking. However, educating yourself about this roof could assist you in preventing problems before they even develop. Here are 5 major roofing myths that you should be especially careful to heed.
- You can add a new layer of shingles on top of an existing layer
You might have read many building codes saying that this practice is acceptable. However, going ahead with it could leave you with the roofing equivalent of a melon that, while looking healthy from the outside, could turn out to taste rotten once you bite into it.
Beneath the shingles is wood sheathing that could rot due to age or leaks. It is best to inspect this layer after the old shingles have been removed, the Chicago Tribune advises.
- You only need to replace flashing during a new roof’s installation
What is flashing? It refers to the metal material that has been put in place to take water from roof openings including pipes, vents and chimneys. It is not always easy to predict when flashing will fail; therefore, you should have it looked at every six months.
If you carry out this inspection, then look for flashing pieces that are cracked or broken; you could also watch out for caulking or sealant that has dried. Use binoculars to let yourself look closely.
- You could improve your roof’s performance by adding attic insulation
If your attic is already sufficiently insulated, then adding, even more, insulation to it could block ventilation openings on the eaves and soffits; as a result, moisture might be trapped. That, in turn, could lead to mold developing on sheathing of the attic interior.
- Gutters are not part of the roofing system
You could easily believe this until you stop to consider that roofs are routinely designed in such a way that they deposit water from the surface. In fact, they are meant to help draw water from the building as a whole; the roofs serve for only the initial part of a longer process.
The gutters help wrap up that process, as water is prevented from running down outside walls. Instead, it is moved away from the building’s foundation.
- Green roofing is a new, experimental form of roofing
You might have put little thought to having what Forbes would call a green roof. That roof could alternatively be called a living or vegetated roof and is where plants would grow on top of the building.
While you might believe such roofs to be a relatively recent trend, Forbes cites one example of a green roof that was installed in Germany over 70 years ago. Good foundations for green roofs today could be provided by roofers in Newcastle upon Tyne and elsewhere.
