So you need 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 material. This procedure is very regular in numerous territories and many material contractual workers don’t perceive any issue with this strategy and have no issue attempting to sell mortgage holders 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 generally be tended to appropriately
There is a decent possibility that your old rooftop had some issue territories including conceivable break spots, regardless of whether you saw them or not. Without detaching the old rooftop and appropriately distinguishing these kinds of issue spots and figuring out where the hole was coming from and venturing out to it is difficult to determine what zones of your rooftop may require some extraordinary consideration.
2.) Any decayed wood under the current material will just deteriorate
There could be territories that have spoiled wood covering up under the old material. These decayed regions should be recognized and supplanted before another rooftop is introduced. Clearly on the off chance that your material temporary worker is just doing a lay-over material establishment, at that point these spoiled zones will stay concealed and just deteriorate as the years go on. Likewise the nails holding down the shingles in territories with decayed wood can’t appropriately carry out their responsibility and you have an a lot higher danger of shingles brushing off in those regions.
3.) Eaves, rakes and valleys need exceptional 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 atmospheres like Massachusetts, where we are found. In the winter 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 solidifying and defrosting that happens all through the winter season. At the point when another rooftop is appropriately introduced the material temporary worker needs to put new aluminum trickle edge around the whole edge of your rooftop.
Next they have to apply a 3 foot wide area of ice and water obstruction around the edge just as in any valleys on your rooftop. At that point they can start to introduce the new material. Without detaching the first material there is no real way to appropriately introduce the new trickle edge or ice and water boundary. On a lay-over kind of material introduce, the material temporary worker is relying on the current items on the home’s rooftop to in any case be satisfactory and have the option to deal with the winter conditions. Very frequently the old items miss the mark whether it was on the grounds that they have outlasted their lifetime, were trashy in any case, or perhaps they were never there in the first place (all to regularly the last is the situation with ice and water hindrance).
4.) Extra material weight is a whole lot of nothing 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 more up to date homes this isn’t an issue, anyway numerous more seasoned homes have rafters that are viewed as undersized by the present surrounding norms. It isn’t extraordinary to see 2×6 beam frameworks on a large number of these houses. Presently by and large a 2×6 beam is undersized in any case and you surely would prefer not to include the heaviness of another material layer over an old material layer to these effectively undersized crossbeam frameworks. With more current rooftops utilizing 2×10, 2×12, built supports, and so on the weight isn’t generally as quite a bit of an issue.
5.) Shorter rooftop future
Most mindful material contractual workers concur that a lay-over rooftop will diminish the new rooftop’s lifetime by about 25%. This reality alone implies that any cash you may have spared by doing a lay-over, rather than a detach and new rooftop introduce, was just a transient investment funds. What’s more, you currently have 2 layers of material that should be evacuated whenever your rooftop is done and that will likewise add more cost to the activity
