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

1. ) Areas that have or perhaps had leaks aren't always be resolved appropriately

There is usually a good probability that your ancient roof had certain problem areas including possible leak spots, regardless of whether you noticed these people or not. Without getting from the old roof and properly discovering these kinds of trouble spots and determining where the leak seemed to be coming from and even visiting it is definitely impossible to share with exactly what areas of the roof may will need some special consideration.

2. ) Any kind of rotted wood underneath the existing roofing will only get worse

There might be locations that have rotted wood hiding under the old roofing. These types of rotted areas should be identified and replaced before a brand new roof is mounted. Obviously if the roofing contractor is definitely only doing some sort of lay-over roofing assembly then these rotted areas will continue to be covered up in addition to only get even worse because the years move on. Also the particular nails working the shingles in areas with rotted wood cannot properly perform their job in addition to you have a much higher risk associated with shingles blowing away from in those regions.

3. ) Eaves, rakes and miles need special remedy

This is a big 1. The eaves, rakes and valleys regarding your house will need special attention when your home's roof is being installed. This is especially important in colder climates like Ma, where we are situated. In the wintertime time the eaves of your property are under assault by Mother Characteristics, whether it be through ice dams, snow build up, or perhaps the constant freezing and thawing that happens through the winter time. When a fresh roof is properly installed the roofing contractor needs to be able to put new light weight aluminum drip-edge around the entire perimeter associated with your roof.

Subsequent they need to be able to apply a several foot wide section of ice & water barrier throughout the perimeter as okay as in any valleys on the roof. Then these people can begin to setup the new roofing. Without tearing off the original roofing there is no way to appropriately install the fresh drip-edge or glaciers & water buffer. On a lay-over sort of roofing mount, the roofing service provider is relying on typically the existing products around the home's roof in order to still be up to par and also handle the winter conditions. All also often the old products fall quick whether it had been because they have outlived their lifetime, had been sub-par to start with, or possibly they were never right now there to begin with (all to usually the latter will be the case with snow & water barrier).

4. ) Extra roofing weight is no good for aged trusses

One regarding the more clear problems with a lay-over re-roof is typically the added weight of the extra coating of shingles. On most newer homes this may not be an issue, however many older home owners have rafters of which are considered undersized by today's framing standards. It is not necessarily rare to see 2�6 rafter systems on the subject of many of these houses. Now inside most situations a new 2�6 rafter will be undersized to start with and you also surely don't wish to be including the weight of a new roofing layer on top involving an old roofing layer to these already undersized rafter systems. With new roofs using 2�10, 2�12, engineered trusses, etc . the pounds isn't always since much of the issue.

5. ) Shorter roof living expectancy

Most liable roofing contractors consent that a lay-over roof will reduce the new roof's lifetime can be 25%. This fact only means that any cash you might include saved by doing a lay-over, as opposed in order to a tear-off in addition to new roof set up, was only a new short term personal savings. In addition, you now have a couple of layers of roofing that will must be removed the following time your roof is done which will also add a lot more cost to the job
