So a person need a brand-new roof and are trying to make a decision whether or not really to try in addition to put some money aside by possessing the new roof installed over a current layer of roofing. This technique will be quite common inside many areas and a lot of roofing contractors no longer see any difficulty with this method and even have no problem striving to sell homeowners over a lay-over or perhaps go-over as this particular technique is named. They are incorrect.
5 Top Causes A Lay-Over Or Go-Over Is actually a Bad Idea When Re-Roofing
1. ) Regions that have or perhaps had leaks cannot always be tackled appropriately
There is definitely a good possibility that your ancient roof had several problem areas including possible leak spots, whether or not you noticed these people or not. Without getting off of the old roof and properly determining these kind of trouble spots and determining where the leak has been coming from and even planing a trip to it will be impossible to share with precisely what areas of your own roof may require some special attention.
2. ) Any rotted wood under the existing roofing will only get worse
There could be regions that have rotted wood hiding beneath the old roofing. These kinds of rotted areas have to be identified and replaced before a brand new roof is installed. Obviously if your current roofing contractor is only doing the lay-over roofing set up then these rotted areas will continue to be covered up plus only get even worse as the years proceed on. Also the nails holding down typically the shingles in regions with rotted real wood cannot properly do their job plus you have a much higher risk involving shingles blowing off in those areas.
3. ) Eaves, rakes and valleys need special therapy
This can be a big a single. The eaves, rakes and valleys involving your house will need special attention if your home's roof is being mounted. This is specifically important in colder climates like Ma, where our company is positioned. In the wintertime time the eaves of your property are under strike by Mother Characteristics, whether it be through snow dams, snow build up, or just typically the constant freezing and thawing that takes place throughout the winter time of year. When a fresh roof is appropriately installed the roofing contractor needs to put new aluminum drip-edge around the particular entire perimeter associated with your roof.
Subsequent they need to apply a three or more foot wide section of ice and water barrier around the perimeter as okay as in any kind of valleys on the roof. Then roofing business near me can begin to install the new roofing. Without tearing away from the original roofing there is no way to effectively install the new drip-edge or ice cubes & water barrier. Over a lay-over type of roofing mount, the roofing contractor is relying on typically the existing products around the home's roof to still be up to par and also handle the winter season conditions. All also often the aged products fall brief whether it had been since they have outlived their lifetime, have been sub-par to begin with, or possibly these people were never right now there to begin using (all to often the latter will be the case with ice & water barrier).
4. ) Additional roofing weight is no good for older rafters
One of the more clear problems with a lay-over re-roof is the particular added weight associated with the extra layer of shingles. Of all newer homes this is not an issue, however many older real estate have rafters of which are considered undersized by today's framing standards. It is not unheard of to see 2�6 rafter systems in many of these kinds of houses. Now throughout most situations the 2�6 rafter is usually undersized to get started with so you surely don't need to be putting the weight of a new roofing coating on top associated with an old roofing layer to these kinds of already undersized rafter systems. With more recent roofs using 2�10, 2�12, engineered trusses, and so forth the weight isn't always while much of the issue.
5. ) Shorter roof life expectancy
Most responsible roofing contractors consent that a lay-over roof will decrease the new roof's lifetime by about 25%. This fact only means that any money you might have got saved by doing a lay-over, as opposed in order to a tear-off in addition to new roof mount, was only some sort of short term cost savings.
