So a person need a fresh roof and are usually trying to determine whether or not necessarily to try in addition to put some money aside by having the new roof installed over a preexisting layer of roofing. This technique is usually quite common inside many areas and a lot of roofing contractors may see any issue with this method and have no problem trying to sell house owners over a lay-over or even go-over as this kind of technique is known as. They are inappropriate.

5 Top Causes A Lay-Over Or even Go-Over Is actually a Negative Idea When Re-Roofing

1. ) Places that have or perhaps had leaks aren't always be dealt with effectively

There is usually a good chance that your aged roof had some problem areas including achievable leak spots, whether or not you noticed these people delete word. Without getting off of the old roof and properly figuring out these kind of trouble places and determining wherever the leak was coming from and even visiting it is usually impossible to inform precisely what areas of the roof may need some special attention.

2. ) Any rotted wood below the existing roofing will only get worse

There can be places that have rotted wood hiding under the old roofing. These kinds of rotted areas have to be identified and substituted before a fresh roof is set up. Obviously if your current roofing contractor is usually only doing a new lay-over roofing installation then these rotted areas will continue to be covered up in addition to only get worse as the years get on. Also typically the nails working the particular shingles in areas with rotted solid wood cannot properly carry out their job in addition to you have a far higher risk of shingles blowing off in those areas.

3. ) Eaves, rakes and valleys need special remedy

It is a big one particular. The eaves, rakes and valleys involving your house require special attention whenever your home's roof is being installed. This is especially important in chillier climates like Massachusetts, where we have been located. In the winter time the eaves of your house are under assault by Mother Nature, unique through cool dams, snow build up, or maybe the particular constant freezing and thawing that occurs over the winter season. When a fresh roof is correctly installed the roofing contractor needs to put new aluminium drip-edge around the entire perimeter involving your roof.

Following they need to be able to apply a three or more foot wide section of ice & water barrier throughout the perimeter as okay as in any kind of valleys on your own roof. Then these people can begin to put in the new roofing. Without tearing off of the original roofing there is simply no way to effectively install the brand new drip-edge or glaciers & water barrier. On a lay-over kind of roofing install, the roofing builder is relying on the particular existing products around the home's roof to still be back up to par and be able to handle the winter season conditions. All also often the old products fall short whether it was mainly because they have outlived their lifetime, had been sub-par to start with, or perhaps they were never right now there to begin with (all to generally the latter could be the case with ice cubes & water barrier).

4. ) Additional roofing weight is no good for older trusses

One associated with the more apparent issues with a lay-over re-roof is the added weight associated with the extra level of shingles. Of all newer homes this is not an issue, even so many older homes have rafters that are considered small by today's framing standards.

With new roofs using 2�10, 2�12, engineered trusses, etc . the pounds isn't always while much of an issue.

5. ) Shorter roof living expectancy

Most accountable roofing contractors agree that a lay-over roof will lower the new roof's lifetime by about 25%. This fact on your own means that anything you might have saved by using a lay-over, as opposed to be able to a tear-off and even new roof install, was only a new short term savings. In addition, an individual now have two layers of roofing that will must be removed the up coming time your roof is done which will also add more cost to the job
