Hi there, my name is Darby Mitchells. I am here to talk to you about eavestrough, or gutter, installations. The roof on your home features a number of components that direct rainwater to the edges. From there, the eavestrough allow water to run straight to the downspouts. The downspouts direct water to a drain that keeps the moisture away from the house. In addition to protecting your roofing materials from damage, gutters make it comfortable to walk under your roofline during heavy downpours. Without eavestrough, a heavy stream of water would pour over the edges of your roof at all times. I will discuss the benefits of installing and maintaining gutters on my site. I will also share information about gutter materials and installation techniques. Thanks for coming to my website.
If your roof is old and it is time to replace it, you can either tear off the shingles off the roof or install the new shingles on the old ones. The first option looks easy and relatively cheap, but it does have its dangers. Here are some of the complications you may face for layering shingles:
You Risk Covering Damaged Roof Sheathing
If your roof is damaged to the point where you need to replace the shingles, then there are high chances that other parts of the roof are also damaged. There are some roof damages that you can't just know about by looking at the shingles.
Tearing off the old shingles will give you the chance to evaluate the condition of the deck and determine whether it also needs a replacement or repair. If you just place the new shingles over the old ones, you risk covering the damages, which may lead to premature damage to the roof.
You Risk Overloading the Roof
This is probably one of the riskiest things about layering shingles. Many houses aren't designed to handle more than one layer of shingles. If you are laying new shingles over old ones, you may be giving your roof too much weight to handle. It may not collapse immediately, but its durability will be affected and it may collapse if further weight is added to it; for example when snow accumulates on the roof.
Shingles Are Designed For Flat Surfaces
Another thing you should know is that shingles are designed to be used on flat surfaces. The shingles risk of damage, such as cracking, increases if they are used on uneven surfaces. Unfortunately, this is what is likely to happen if you are layering shingles. This is because the old shingles are likely to be curled after spending a lot of time on the roof and being exposed to different weather elements.
You Risk Voiding Your Warranty
Due to the above issues or more, there is a high chance that the new installation of shingles may not be perfect. If that happens, and it leads to premature damage of the shingles, it may void the manufacturer's warranty. This is because the manufacturer will argue, and rightly so, that the damage is as a result of your negligence.
Therefore, this is a decision you shouldn't take lightly because it will affect the integrity and durability of your roof going forward. In fact, you should listen to your roofing contractors advise keenly before layering shingles on your roof. Visit a site like http://www.allamericanroofing.com for more help.Share
