It’s time to replace your roof and the decision is focused on removing and replacing the existing asphalt roofing or adding new asphalt roof to the old installation. That’s a dilemma indeed. But you’ll have all the information you need to go the right route if you learn all about the tips and tricks coming from the experts in roofing Haverhill MA.
Determine the number of layers the roofing materials that are installed are in your house. Before, multiple layers of asphalt were allowed. Right now, only two layers are acceptable in most cities. Hire a roof inspector or roofing contractor to know how many asphalt layers there are in your roof. If there were more than two, then high are the chances that you’ll have to do a full tear-off. To confirm the limitations of roof replacement, visit the local department managing buildings and permits to ensure that you’re complying with the codes of your region.
How Long Does Asphalt Roofing Last?
The lifespan of asphalt roofing is between 15 and 25 years. The roofing material will hold better, depending on the shingle type installed and the location of your home. A few other roofing materials maybe more suitable than others for certain areas. Asphalt is well regarded as a robust and durable material, but factors such as aging and inclement weather could affect its lifespan.
The roofing problems to be looked for during roof inspection include the tell-tale signs of wear and tear characterized by asphalt curling and the loss of granules. If your roofing shows signs leaking, then it’s important to determine what’s causing the problem so it can be fixed.
The areas around the flashes, chimneys, roof vents and skylights should be checked. Pay special attention to the areas that may be causing ice dams. Other factors to consider include strong winds and indoor condensation.
Should You Consider Reroofing?
The process that pertains to the construction of new shingles over the existing ones is called re-roofing. Such a project is less expensive and is not labor-intensive. Re-roofing creates less mess, which results in minimal cleanup or removal of materials. It also takes lesser time to complete than a tear-off.
However, there will be no visual inspections to know whether the roof system, including the roof deck, has problems under the existing shingles. Also, the underlayment won’t be inspected or replaced for damage. There is also no chance to replace ice and water shields and skylight, wall, and roof flashings.
Should You Consider a Tear-Off?
Before you install new shingles, a tear-off process is required. It involves the complete removal of existing shingles from the roof to the deck. Unlike re-roofing, the process includes removing all old materials for easy inspection of all the critical components and structure of the roof.
Once all the roofing materials are removed, it’s easier to replace the wood boards if needed. It is also possible to install new underlayment, which is also known as felt paper. Certain elements, such as shields and flashings, are easily replaced to protect the roof against ice dams.
