your five Reasons Not in order to Possess a New Roof Installed Over an Old Roof

So an individual need a fresh roof and are trying to decide whether or certainly not to try and stretch your budget by having the new roof installed over an existing layer of roofing. This technique will be quite common inside many areas and a lot of roofing contractors no longer see any problem with this particular method plus have no problem seeking to sell property owners on a lay-over or perhaps go-over as this particular technique is named. They are wrong.

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

1. ) Regions that have or had leaks still cannot always be addressed appropriately

There is usually a good probability that your good old roof had several troublesome areas including probable leak spots, no matter if you noticed these people or not. Without getting off of the old roof and properly identifying these types of trouble spots and determining in which the leak had been coming from and even traveling to it is impossible to inform what areas of your current roof may require some special interest.

2. ) Virtually any rotted wood beneath the existing roofing will only get worse

There may be regions that have rotted wood hiding within the old roofing. These kinds of rotted areas need to be identified and changed before a new roof is installed. Obviously if the roofing contractor is definitely only doing some sort of lay-over roofing set up then these rotted areas will continue to be covered up and only get even worse as the years move on. Also typically the nails working the particular shingles in regions with rotted real wood cannot properly carry out their job and you have a much higher risk of shingles blowing away from in those places.

3. ) Eaves, rakes and valleys need special treatment

This is a big one particular. The eaves, rakes and valleys regarding your house need special attention if your home's roof is being set up.

In the winter season time the eaves of your house are under attack by Mother Nature, whether it be through snow dams, snow create up, or perhaps the constant freezing and thawing that happens throughout the winter time. When a fresh roof is effectively installed the roofing contractor needs to be able to put new lightweight aluminum drip-edge around typically the entire perimeter regarding your roof.

Subsequent they need to apply a 3 foot wide area of ice and water barrier throughout the perimeter as okay as in virtually any valleys on your current roof. Then they can begin to put in the new roofing. Without tearing off the original roofing there is zero way to properly install the brand new drip-edge or ice cubes & water barrier. On a lay-over kind of roofing mount, the roofing service provider is counting on the existing products around the home's roof in order to still be back up to par and be able to handle the winter season conditions. All too often the outdated products fall brief whether it absolutely was since they have outlived their lifetime, had been sub-par to commence with, or possibly these people were never right now there to begin together with (all to often the latter may be the case with snow & water barrier).

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

One involving the more clear difficulties with a lay-over re-roof is the added weight associated with the extra layer of shingles. On most newer homes this is simply not an issue, nevertheless many older home owners have rafters that are considered small by today's surrounding standards. It is not necessarily unheard of to see 2�6 rafter systems in many of these kinds of houses. Now within most situations some sort of 2�6 rafter will be undersized to get started with and you also surely don't need to be putting the weight of any new roofing layer 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, etc . the weight isn't always because much of an issue.

5. ) Shorter roof life expectancy

Most responsible roofing contractors concur that a lay-over roof will reduce the new roof's lifetime can be 25%. This fact by yourself means that anything you might possess saved by doing a lay-over, as opposed in order to a tear-off and new roof set up, was only a short term cost savings. In addition, you now have two layers of roofing that will have to be removed the following time your roof is done which will also add a lot more cost to the particular job
