a few Reasons Not to Have a very New Roof Installed Over a great Old Roof

So a person need a brand-new roof and will be trying to make a decision whether or not to try in addition to stretch your budget by getting the new roof installed over an existing layer of roofing. This technique will be quite common within many areas and many roofing contractors no longer see any problem on this method in addition to have not a problem trying to sell house owners on the lay-over or perhaps go-over as this specific technique is referred to as. They are incorrect.

5 Top Causes A Lay-Over Or even Go-Over Can be a Bad Idea When Re-Roofing

1. ) Areas that have or even had leaks aren't always be addressed appropriately

There is a good possibility that your old roof had some troublesome areas including feasible leak spots, regardless of whether you noticed them or not. Without getting off of the old roof and properly identifying these kinds of trouble locations and determining exactly where the leak was coming from and traveling to it is usually impossible to inform just what areas of your roof may need some special consideration.

2. ) Any rotted wood beneath the existing roofing will only obtain worse

There could be regions that have rotted wood hiding beneath the old roofing. These rotted areas need to be identified and substituted before a new roof is set up. Obviously if your own roofing contractor is certainly only doing a new lay-over roofing unit installation then these rotted areas will continue to be covered up and even only get a whole lot worse because the years proceed on. Also the particular nails working typically the shingles in places with rotted solid wood cannot properly carry out their job and even you have a lot higher risk involving shingles blowing off in those regions.

3. ) Eaves, rakes and miles need special treatment

It is a big 1. Go here , rakes and valleys regarding your house require special attention any time your home's roof is being set up. This is especially important in frigid climates like Ma, where we have been located. In the wintertime time the eaves of your house are under attack by Mother Characteristics, be it through ice dams, snow develop up, or perhaps the particular constant freezing in addition to thawing that takes place through the entire winter time. When a brand new roof is correctly installed the roofing contractor needs to be able to put new aluminum drip-edge around typically the entire perimeter associated with your roof.

Next they need in order to apply a several foot wide section of ice and water barrier throughout the perimeter as well as in any kind of valleys on your current roof. Then these people can begin to setup the new roofing. Without tearing off the original roofing there is no way to correctly install the brand new drip-edge or ice & water obstacle. On a lay-over type of roofing install, the roofing service provider is relying on typically the existing products on the home's roof in order to still be back up to par and be able to handle the winter conditions. All also often the older products fall quick whether it had been since they have outlived their lifetime, were sub-par to begin with, or perhaps these people were never right now there to begin using (all to often the latter may be the case with glaciers & water barrier).

4. ) Additional roofing weight is not any good for aged rafters

One associated with the more apparent difficulties with a lay-over re-roof is typically the added weight of the extra level of shingles. Of all newer homes this is simply not an issue, even so many older home owners have rafters of which are considered small by today's mounting standards. It is not unusual to see 2�6 rafter systems on the subject of many of these kinds of houses. Now within https://zenwriting.net/forkpyjama7/why-you-must-use-a-residential-roofing-firm-to-your-home of 2�6 rafter is definitely undersized to begin with and you surely don't need to be incorporating the weight of a new roofing coating on top involving an old roofing layer to these types of already undersized rafter systems. With new roofs using 2�10, 2�12, engineered trusses, etc . the excess weight isn't always as much of an issue.

5. ) Shorter roof life expectancy

Most liable roofing contractors concur that a lay-over roof will reduce the new roof's lifetime can be 25%. This fact only means that any money you might possess saved by using a lay-over, as opposed in order to a tear-off and new roof install, was only the short term cost savings. In addition, an individual now have two layers of roofing that will should be removed the next time your roof is done and that will also add even more cost to the job

Tear-Off And then Re-Roof Is obviously Superior

Well, I just presented you 5 excellent reasons to split out of your old roofing then install your own new roof. Indeed it can always be cheaper in the particular short term to do a go-over on your aged roof, but, in the long phrase it will cost you more. All of us never recommend this technique to the customers. We always advise completely tearing of the old roofing, fixing any actual problems, then installing a fresh, lovely new roof of which will outlast any lay-over roof since well as better protect our consumers'
