Getting a roof replacement is not a small job. There are several factors to consider when getting a roof replacement, including the materials and labor costs, where you live, and obtaining permits before hiring a contractor. Adding a new set of shingles over an existing layer can be a quick and inexpensive way to get a new roof without completely tearing off the old roof. But there are some things to keep in mind before making the decision. Adding a second layer of shingles to your roof may seem like a good idea, but it can cause problems. Adding the weight of the second layer of shingles can lead to surface defects and infiltration of ventilation. It can also cause damage to your roof’s insulation, decking, and trusses.
Removing the first layer of shingles can save you time and money. Removing the first layer of shingles also lets you see the condition of your roof. If there are leaks, you may need to replace your roof. You also may not be able to see algae growth or damaged wood. Re roofing is a good option if you need more time or money to replace your roof. If you want to add a second layer of shingles, you must remove the old coating. The original layer of shingles is usually nailed in place. Nail penetration may cause the shingles to come loose and blow off. The shingles should also be kept from an uneven surface. Obtaining permits before hiring a contractor for roof replacement can save you money and trouble down the road. Not only will the project look good on paper, but it will also protect you from potential fines and legal issues. Obtaining a roof replacement permit can also help protect your property and ensure your new roof is built to code. A permit also serves as proof of work, which is essential if you plan to sell your home.
A work record is also vital if you want to file a claim with your insurance company.
Many different regulations go along with obtaining permits. The local building office will have information regarding the requirements for your specific city, and you can also check online. However, many homeowners do not have the time to go through the process. If you work with a contractor, the contractor will have the knowledge and time to ensure the job is done correctly. The process is designed to protect the public and ensure that your home’s structure is built to the proper code. Follow these rules to avoid paying a fine or having your work razed. Depending on the size and complexity of your project, the city may require you to pay for a permit in addition to the construction costs.
