5 Reasons Not to Have a New Roof Installed Over an Old Roof

So you really want another rooftop and are doing whatever it takes not to attempt to set aside some cash by having the new rooftop introduced over a current layer of roofing. This procedure is very normal in numerous spaces and many roofing contractors don’t see any issue with this strategy and have no issue attempting to sell homeowners on a lay-over or go-over as this method is called. They are incorrect.

5 Top Reasons A Lay-Over Or Go-Over Is A Bad Idea When Re-Roofing

1.) Areas that have or had spills can’t forever be tended to appropriately

There is a decent possibility that your old rooftop had some pain points including conceivable hole spots, whether or not you saw them. Without removing the old rooftop and appropriately distinguishing these kinds of pain points and figuring out where the hole was coming from and making a trip to it is difficult to determine what spaces of your rooftop might require some unique consideration.

2.) Any spoiled wood under the current roofing will just deteriorate

There could be regions that have spoiled wood stowing away under the old roofing. These decayed regions should be distinguished and supplanted before another rooftop is introduced. Clearly assuming your roofing contractor is just doing a lay-over roofing establishment then these spoiled regions will stay concealed and just deteriorate as the years continue. Additionally the nails holding down the shingles in regions with spoiled wood can’t as expected do their job and you have a lot higher danger of shingles brushing off in those spaces.

3.) Eaves, rakes and valleys need extraordinary treatment

This is a major one. The overhang, rakes and valleys of your home need unique consideration when your home’s rooftop is being introduced. This is particularly significant in colder environments like Massachusetts, where we are found. In the colder time of year time the roof of your home are enduring an onslaught by Mother Nature, regardless of whether it is through ice dams, snow develop, or simply the steady freezing and defrosting that happens all through the colder time of year season. At the point when another rooftop is appropriately introduced the roofing contractor needs to put new aluminum trickle edge around the whole edge of your rooftop.

Next they need to apply a 3 foot wide segment of ice and water obstruction around the border just as in any valleys on your rooftop. Then, at that point, they can start to introduce the new roofing. Without detaching the first roofing it is basically impossible to appropriately introduce the new trickle edge or ice and water boundary. On a lay-over sort of roofing introduce, the roofing contractor is relying on the current items on the home’s rooftop to in any case be adequate and have the option to deal with the colder time of year conditions. All around very regularly the old items miss the mark whether it was on the grounds that they have outlasted their lifetime, were shoddy in any case, or perhaps they were never there in the first place (all to frequently the last option is the situation with ice and water hindrance).

4.) Extra roofing weight is nothing but bad for old rafters

One of the more clear issues with a lay-over re-rooftop is the additional load of the additional layer of shingles. On most fresher homes this isn’t an issue, but numerous more established homes have rafters that are viewed as small by the present outlining guidelines. It isn’t exceptional to see 2×6 crossbeam frameworks on a significant number of these houses. Presently much of the time a 2×6 crossbeam is small in any case and you absolutely don’t have any desire to add the heaviness of another roofing layer on top of an old roofing layer to these generally modest beam frameworks. With more up to date rooftops utilizing 2×10, 2×12, designed brackets, and so on the weight isn’t dependably as a lot of an issue.

5.) Shorter rooftop future

Most mindful roofing contractors concur that a lay-over rooftop will diminish the new rooftop’s lifetime by around 25%. This reality alone implies that any cash you may have saved by doing a lay-over, instead of a detach and new rooftop introduce, was just a transient investment funds. What’s more, you presently have 2 layers of roofing that should be taken out whenever your rooftop is done and that will likewise add more expense for the job
