The Basics of Roofing Replacement, Tear Off, or Second Layer?
Roof replacement is not a repair that should be delayed. When you think that your roof needs to be repaired. Let’s brush up on these basics before soliciting bids from roofing contractors. Veronica Contracting roofing experts give you all the necessary information regarding the roofing replacement in Toronto.
First, let’s check out with layers of shingles on your roof. It was once common to lay a new shingle roof over the preexisting layer at least once, or in some cases even twice. Even where shingles layering is allowed, applying a new shingles layer over the old shingles layer should be carefully considered in each case on the basis of its pros and cons:
✅ Weight: The basic argument against doing additional layers of asphalt shingles is that the roofing materials can be too heavy for the underlying roof framing. So it can be a structural problem, especially for older houses in downtown Toronto or in Richmond Hill. Roofing contractors often declare that a triple layer of asphalt shingles is equal to a single layer of slate shingles—an exceedingly heavy type of material, and that is true.
✅ Telegraphing: Another big problem with doing a new layer of shingles over existing shingles it’s necessary to essentially repeat some of the surface irregularities that may already be present on the roof. If you’re going to put on a new roof, that may be a big chance that you will get some bubbles, bumps, and waves that should be fixed. Putting a new layer of shingles over existing problems can be a result of a rather not good looking new roof. The best way to fix this problem is to go over the old roof and correct as many problems as you can before you start re-roofing. You need for that just a hammer, some roofing nails, and a handful of shingles to correct bumps, gaps, and protruding nails, of cause if you are going to do that by yourself.
✅ Work and waste reduction: The primary advantage of layering is that it reduces the work involved. Stripping off the existing layer and then laying down a new shingles layer adds more time to the work process. This is not a big deal if roofing professionals are tackling the job—they can strip most roofs in a morning—but if you’re doing the job yourself, it can be a strong argument for roofing right over the old roof.
