So a person need a fresh roof and will be trying to decide whether or not necessarily to try plus put some money aside by having the new roof installed over a preexisting layer of roofing. This technique is definitely quite common inside many areas and many roofing contractors avoid see any difficulty with this particular method and even have no problem attempting to sell homeowners on the lay-over or go-over as this specific technique is called. They are incorrect. 5 Top Factors A Lay-Over Or Go-Over Is A Awful Idea When Re-Roofing 1. ) Regions that have or perhaps had leaks aren't always be resolved appropriately There is a good chance that your aged roof had many problem areas including achievable leak spots, regardless of whether you noticed these people delete word. Without getting off the old roof and properly identifying these types of trouble spots and determining where the leak seemed to be coming from and planing a trip to it is usually impossible to share just what areas of your current roof may want some special interest. 2. ) Virtually any rotted wood underneath the existing roofing will only get worse There can be places that have rotted wood hiding underneath the old roofing. These types of rotted areas should be identified and substituted before a new roof is set up. Obviously if your own roofing contractor is usually only doing the lay-over roofing unit installation then these rotted areas will continue to be covered up plus only get worse as being the years go on. Also the particular nails working the shingles in regions with rotted real wood cannot properly carry out their job and even you have a far higher risk associated with shingles blowing off of in those regions. 3. ) Eaves, rakes and valleys need special remedy It is a big one particular. The eaves, rakes and valleys involving your house need special attention when your home's roof is being set up. This is specially important in chillier climates like Ma, where our company is positioned. In the winter season time the eaves of your house are under attack by Mother Nature, be it through ice cubes dams, snow develop up, or just typically the constant freezing in addition to thawing that takes place through the entire winter time of year. When a fresh roof is effectively installed the roofing contractor needs in order to put new lightweight aluminum drip-edge around the entire perimeter regarding your roof. Next they need to be able to apply a 3 foot wide segment of ice as well as water barrier round the perimeter as okay as in virtually any valleys on your roof. Then they will can begin to install the new roofing. Without tearing away from the original roofing there is not any way to properly install the new drip-edge or snow & water barrier. On the lay-over kind of roofing mount, the roofing contractor is relying on typically the existing products for the home's roof to be able to still be back up to par and be able to handle the winter season conditions. All too often the old products fall brief whether it absolutely was because they have outlived their lifetime, had been sub-par to start with, or perhaps they were never there to begin along with (all to generally the latter is the case with ice cubes & water barrier). 4. ) Added roofing weight is not a good for aged rafters One associated with the more clear difficulty with a lay-over re-roof is the added weight of the extra level of shingles. Of all newer homes this is not an issue, even so many older real estate have rafters that are considered small by today's framing standards. Not necessarily uncommon to see 2�6 rafter systems on many of these kinds of houses. Now throughout most situations a new 2�6 rafter is definitely undersized to begin with and also you definitely don't wish to be including the weight of any new roofing level on top associated with an old roofing layer to these kinds of already undersized rafter systems. With modern roofs using 2�10, 2�12, engineered trusses, and so forth the pounds isn't always as much of a good issue. 5. ) Shorter roof living expectancy Most dependable roofing contractors agree that a lay-over roof will decrease the new roof's lifetime can be 25%. This fact by yourself means that any money you might possess saved by using a lay-over, as opposed in order to a tear-off plus new roof install, was only a new short term financial savings. In addition, you now have two layers of roofing that will should be removed the next time your roof is done which will also add a lot more cost to typically the job Tear-Off After that Re-Roof Is usually Superior Well, I just presented you 5 great reasons to rip out of your old roofing then install your own new roof.
