Shingle Layering, The Good, The Bad, The Ugly.

Before roofers can begin hauling materials onto a roof to start the installation process, they first have to tear off the old shingle layer. This part of the job can be strenuous and can take a lot of time. Depending on how many layers of materials are on the roof, some roof tear-offs can take longer than others.

Some roofers will claim that there are more advantages than disadvantages to layer over a previous layer of shingles. Sure, it may save a buck here or there for a property owner, but the long term effect can be devasting. Relayering can be a convenient timesaver for a roofing crew, but the additional layer of shingles can drastically shorten the life of a roof.

Many city codes state that two layers of shingles are the maximum limit. However, roofers today still find roofs with three or even four shingle layers. Shingle layers and various roofing materials being installed on top of one another is a huge concern that roofers find. That’s when the bad can turn ugly for a homeowner.

Improperly installing material is incredibly hard on the lifespan of the structure of a roof. Trapped heat from layers can cause materials to decompose, different materials on top of one another trap water which can cause leaks, and the weight of many layers can eventually cause risk for the roof sagging between rafters. Sagging creates what looks like ripples or the hills on a rollercoaster. Sagging can cause a roof to collapse. This is the reason why most codes only allow two layers of materials.

 

 

So what’s the good you ask? Aspen Contracting NEVER lays shingles over another layer. We believe in doing the job right from the start. We make sure that our roofing crews safely removed all layers of shingles and the proper materials such as ice and water shield or our Aspen underlayment in installed before they start to shingle a property with beautiful roofing materials.
