Reasons To Not Have A Brand New Roof Installed Over A Classic Roof

So you'll need a new roof and are attempting to decide if you should try to reduce your cost by getting the brand new roof installed over a current layer of roofing. This method is very common in lots of areas, and lots of roofing companies aren't seeing any difficulty with this particular method and also have not a problem selling homeowners on the layover or go over because this strategy is known as. They're wrong.

Areas Which Have Or Had Leaks Can't Continually Be Addressed Correctly

There's a strong possibility that your old roof had some trouble spots including possible leak spots, regardless of whether you observed them or otherwise. Without tearing from the old roof and correctly determining these kinds of roofing company areas and figuring out in which the leak was originating from and visiting it's impossible to inform what regions of your home's roof may require some kind of special attention.

Any Rotted Wood Underneath The Existing Roofing Is Only Going To Worsen

There might be areas which have rotted wood hiding underneath the old roofing. These rotted areas have to be recognized and changed before a brand new roof is installed. Apparently, in case your roofer is just carrying out a layover roofing installation then these rotted areas will stay hidden and just worsen as time continue. Even the nails holding lower the shingles in areas with rotted wood cannot correctly get the job was done, and you've got a significantly greater chance of shingles coming off in individuals areas.

Eaves, Rakes And Valleys, Need Special Therapy

This can be a big one. The eaves, rakes, and valleys of your property need particular attention whenever your home's roof has been installed. This is particularly essential in cooler environments like Massachusetts, where we're situated. During the cold months time the eaves of your property they are under attack by Nature, whether it's covering efficient through ice dams, snow develop, or simply the continual freezing and thawing that happens through the winter months. Whenever a new roof is correctly installed the roofer must put new aluminum drip edge around the entire perimeter of the ceiling.

Next, they have to use 3 feet wide portion of ice & water barrier around the edge plus any valleys in your roof. They can start to set up the brand new roofing.

Very frequently that old things are unsuccessful whether or not this was because they have outlived their lifetime were sub-component to start with, or possibly these were never there to start with (all too frequently the second may be the situation with ice & water barrier).

Extra Roofing Weight Isn't Any Great For Old Rafters

One of the most apparent issues with a layover re-roof may be the added weight of the extra layer of shingles. Of all more recent homes, this isn't a problem. However, many older homes have rafters which are considered undersized by today's framework standards. It's not uncommon to determine 2×6 beam systems on a number of these houses. Now in many situations, a 2×6 beam is undersized to start with and also you certainly don't wish to be adding the load of the new roofing layer on the top of the old roofing layer to those already undersized rafter systems. With more recent roofs using 2×10, 2×12, designed trusses, etc. the load is not always because of a problem.

Shorter Roof Existence Expectancy

Most responsible roofing companies agree that the layover roof will reduce the new roof's lifetime by about 25%. This fact alone implies that anything you may have saved using a pause, instead of a tear-off and new roof install, was just a short term savings. Additionally, you have 2 layers of roofing that will have to be removed next time your homes roof is completed which will include more cost towards the job.
