New Roofing – Overlay or Tear Off

Another Leak!!! You have pans within the floor, balanced in your furniture and also the weather man states it will not let up. You are likely to have times of catching the drips and emptying the pans. You cringe while you be careful about your kids drag their dog on the towel to clean up a few of the drips and merely slide beyond the pan around the kitchen floor!

Time for you to Fix this Roof Problem For good!!!

BUT… how can you repair the problem? Have you got the present roofing materials torn off and replaced? Or have you got a new roof overlaid on the top from the old roof?

Overlays can help you save the roofer’s time, cut lower around the labor, and also you will not have shingles to get rid of or spend the money for roofer to get it done for you personally.

But think about this…

Your present roof must only be one layer to be able to lay flat over the entire roof of your property. Your homes roof may sag in certain areas of the rooftop which may mean you most likely must have your roofer place in more support beams. If it’s sagging now, the following layer on the top will undoubtedly increase the weight and make it sag more between your support beams. Which will surely cause more stress on the top and make the shingles to split up one in the other and you know what… another leak. If you haven’t checked, you have to ensure there aren’t other issues using the roofing deck. In case your roof meets many of these needs, then an overlay might be your very best answer.

Whichever method you utilize, overlay or tear off, look for proper ventilation inside your attic room. Consistent keeping soffit and ridge vents provide maximum mix ventilation.


Here is a checklist that will help you determine whether an entire tear from your present roofing system should be thought about.

A Lot Of Layers

Determine the number of existing roofing layers you will find. You need to have only one layer before adding another roofing layer into it. If you have several layers, all layers have to be removed before you apply your brand-new roofing material. This can be a code requirement in many locations and building codes rarely accept greater than two layers. The local department of creating inspectors will gladly supply the needs for that code for the compliance.

Bad Decking

Whenever you walk across your homes roof, spongy or bouncy areas or sag between your rafters or trusses indicate you will probably have failing roof deck or damage. Damage might be from dry rot that is wood rot from kinds of fungi and when not removed, will spread with other wooden areas. Look for de-lamination from the plywood because of glue failure. With bad decking, tearing from the entire roof is essential. It’s more cost-effective to exchange unhealthy decking now than to need to switch the deck and also the roofing material a couple of years from now. If bad decking is stated prior to the roofing work begins, you won’t possess a warranty in your new roof.

Poor Condition of Existing Roof

When the existing roofing tabs show indications of putting on out by curling around the edge or seem to be crooked within their placement, these irregularities will ultimately surface the brand new layer of roofing material. It might look okay when first done but because the brand new shingles settle lower around the old irregular roofing, the brand new material will require on the ridges and sag. To avoid this, an entire tear-off and substitute is suggested.

Life Time

Although it is not documented, professional in roofing agree that the overlaid roof have a shorter lifespan. The shingles of the overlay is going to be possess a shortened lifespan of 10% and perhaps around 20%.

Incompatible Shingles

Heavy architectural shingles may be used to cover a lighter strip shingle for example 3-tabs will give you a great-searching roof. But never make use of a lighter in weight shingle to try and cover huge shingle, It’ll show all of the bumps and ridges in the older roof and can appearance of low quality.

Ice Dams

It’s fun to determine the icicles coming lower in the eaves. All of them form differently and appear like they’d be so cold. But ice dams originating from your homes roof may bring one other issue towards the integrity of the roofing. In which the average winter temperature could be hovering around freezing or below 30° F, there aren’t any ice and water protective membranes, a complete roof tear off is the best guarantee. Twenty years old roofs may show no manifestation of ice and water protection or show indications of any prior problems. But they’re susceptible to getting many dollars price of damage if the unusual cold front blows through. Nowadays we have all seen our weather altering and a lot of our winters giving us more snow and cold than we have seen before.
