You require a brand-new roofing and are attempting to determine whether or not to try and conserve some money by having the new roof installed over an existing layer of roofing. This strategy is fairly common in many areas and also numerous roofing contractors do not see any type of issue with this approach as well as have no problem attempting to market home owners on a lay-over or go-over as this technique is called. They are incorrect.
5 Top Reasons A Lay-Over Or Go-Over Is A Negative Idea When Re-Roofing
1.) Locations that have or had leaks can’t constantly be dealt with properly
There is a great chance that your old roof covering had some problem locations including possible leakage spots, whether you observed them or not. Without detaching the old roof as well as appropriately determining these sorts of problem areas as well as determining where the leakage was originating from as well as traveling to it is impossible to tell exactly what areas of your roof covering might need some unique interest.
2.) Any type of decayed timber under the existing roofing will just get worse
These rotted areas require to be determined and changed prior to a new roofing is installed. Certainly if your roofing professional is only doing a lay-over roofing installment then these decomposed areas will stay covered up and also just get even worse as the years go on.
3.) Eaves, rakes as well as valleys demand unique treatment
This is a big one. The eaves, rakes as well as valleys of your home requirement unique interest when your home’s roof covering is being installed. This is specifically important in chillier environments like Massachusetts, where we lie. In the winter time the eaves of your house are under fire by Nature, whether it is via ice dams, snow build up, or just the constant cold and thawing that occurs throughout the winter. When a brand-new roofing is appropriately mounted the roofing contractor should put brand-new aluminum drip-edge around the whole perimeter of your roofing system.
Next they need to use a 3 foot wide section of ice & water obstacle around the border in addition to in any type of valleys on your roof. Then they can begin to install the new roofing. Without detaching the original roofing there is no way to effectively install the new drip-edge or ice & water obstacle. On a lay-over type of roofing mount, the roofing specialist is trusting the existing items on the residence’s roofing system to still depend on par and have the ability to take care of the winter months problems. All frequently the old products fall short whether it was due to the fact that they have outlived their lifetime, were crappy to begin with, or perhaps they were never ever there to start with (all to usually the latter holds true with ice & water barrier).
4.) Additional roofing weight is no great for old rafters
Currently in the majority of scenarios a 2 × 6 rafter is undersized to begin with as well as you definitely don’t want to be adding the weight of a brand-new roofing layer on top of an old roofing layer to these already undersized rafter systems. With newer roofing systems utilizing 2 × 10, 2 × 12, engineered trusses, and so on the weight isn’t always as much of a concern.
5.) Shorter roofing life expectancy
A lot of liable roofer agree that a lay-over roofing system will lower the new roof covering’s life time by regarding 25%. This truth alone implies that any type of cash you may have saved by doing a lay-over, in contrast to a tear-off and also brand-new roof set up, was just a short-term financial savings.
