So one desire a new roof and are striving to determine whether or not to try and conserve some hard earned cash by getting the brand-new roof installed over an existing layer of roofing. This technique is actually rather frequent in numerous places as well as lots of roofing service providers don’t see virtually any problem having this technique and receive no complication trying to offer home owners on a lay-over or go-over as this method is named. They are actually wrong.

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

1.) Locations that have or offered leaks won’t be able to always be actually discussed adequately

There is a good prospect that the old roof needed some complication places consisting of feasible puncture areas, whether you noticed them or not. Without tearing off the old roof as well as properly determining these types of difficulty areas as well as figuring out where the hole was actually coming out of as well as traveling to it’s inconceivable to tell what places of the roof may require some special recognition.

2.) Any rotted wood under the existing roofing is going to merely receive more serious

There might be actually areas that have rotted wood hiding under the past roofing. These rotted locations should be recognized as well as restored before a new roof is actually installed. Obviously if your roofing service provider is only carrying out a lay-over roofing installation at that point these rotted locations will certainly continue to be covered up as well as only get more serious as the years go on. Even the nails carrying down the shingles in areas having rotted wood can’t the right way do their job and one have a considerably higher danger of shingles blowing off in those places.

3.) Eaves, rakes and valleys require unique therapy

This is a large one. The eaves, rakes as well as valleys of your home demand special attention when the home’s roof is being installed. This is actually specifically critical in colder climates like Massachusetts, where we are found. In the winter time the eaves of your house are under fit by Mother Traits, whether it’s with ice dams, snow build up, or just the constant freezing and thawing that occurs throughout the winter period. When a brand-new roof is actually appropriately installed the roofing contractor should place new light weight aluminum drip-edge around the whole entire outline of your roof.

Next they want to put on a 3 foot large segment of ice & water barrier around the outline in addition to in any valleys on the roof. Then they may start to install the new roofing. Without tearing off the initial roofing there is no manner to appropriately install the brand-new drip-edge or ice & water obstacle. On a lay-over type of roofing install, the roofing service provider is actually adding up on the existing products on the property’s roof to still be actually up to par as well as be actually ready to handle the winter season conditions. All too regularly the traditional products fail whether it’s because they have actually outlived their life time, were actually sub-par to start having, or it’s possible they were never there to start having (all to often the latter is actually the circumstances having ice & water hurdle).

4.) Additional roofing weight is actually no good for past rafters

One of the more apparent issues by having a lay-over re-roof is the added weight of the additional layer of shingles. On a lot of newer homes this is not an issue, having said that countless earlier residences offer rafters which are thought of undersized by today’s framing requirements. It isn’ts uncommon to view 2 6 rafter processes on numerous of these houses. Currently in a lot of conditions a 2 6 rafter is undersized to begin having as well as one certainly do not desire to be actually including the weight of a brand-new roofing layer on top of an past roofing layer to these presently undersized rafter processes. By having newer roofs utilizing 2 10, 2 12, engineered trusses, etc. the weight isn’t really always as much of an issue.

5.) Lessened roof life span expectancy

Many responsible roofing contractors concur that a lay-over roof will lower the brand-new roof’s life time by about 25 %. This certainty alone means that any money one might have actually conserved by doing a lay-over, as opposed to a tear-off and new roof install, was actually just a short phrase savings. In addition, one now offer 2 layers of roofing that will certainly have to be removed the following time your roof is accomplished as well as that will also add more cost to the project

Tear-Off Then Re-Roof Is Constantly Superior

Well, I merely provided 5 incredibly good causes to tear off the traditional roofing as well as then install your brand-new roof. Yes it is able to be cheaper in the short phrase to carry out a go-over on your old roof, yet, in the long phrase it will cost you more. You never ever advise this approach to the consumers. We continually recommend entirely tearing of the traditional roofing, patching any underlying problems, then installing a fresh, exquisite brand-new roof that is going to outlast every lay-over roof as adequately as more desirable shield the consumers’ homes.
