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

So you need another rooftop and are making an effort not to attempt to set aside some cash by having the new rooftop introduced over a current layer of material. This strategy is very regular in numerous regions and many material contractual workers don’t perceive any issue with this strategy and have no issue attempting to sell property holders on a lay-over or go-over as this system 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 breaks can’t generally be tended to appropriately

There is a decent shot that your old rooftop had some issue zones including conceivable hole spots, regardless of whether you saw them or not. Without removing the old rooftop and appropriately recognizing these kinds of inconvenience spots and figuring out where the hole was coming from and venturing out to it is difficult to determine what territories of your rooftop may require some exceptional consideration.

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

There could be regions that have decayed wood covering up under the old material. These spoiled regions should be recognized and supplanted before another rooftop is introduced. Clearly whether your material contractual worker is just completing a lay-over material establishment then these spoiled territories will stay concealed and just deteriorate as the years go on. Likewise the nails holding down the shingles in regions with spoiled wood can’t appropriately carry out their responsibility and you have an a lot higher danger of shingles brushing off in those territories.

3.) Eaves, rakes and valleys need unique treatment

This is a major one. The overhang, rakes and valleys of your home need uncommon 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 overhang 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 contractual worker needs to put new aluminum trickle edge around the whole edge of your rooftop.

Without detaching the first material there is no real way to appropriately introduce the new trickle edge or ice and water obstruction. On a lay-over kind of material introduce, the material contractual worker is depending on the current items on the home’s rooftop to at present 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 shoddy in the first place, or perhaps they were never there in any case (all to regularly the last is the situation with ice and water obstruction).

4.) Extra material weight is a whole lot of nothing for old rafters

One of the more evident issues with a lay-over re-rooftop is the additional load of the additional layer of shingles. On most more current homes this isn’t an issue, anyway numerous more seasoned homes have rafters that are viewed as undersized by the present confining measures. 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 the first place and you absolutely 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 brackets, and so forth the weight isn’t generally as a lot of an issue.

5.) Shorter rooftop future

Most dependable 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 completing a lay-over, instead of a detach and new rooftop introduce, was just a transient investment funds.
