"I had a great experience working with Guardian Roofing Systems. From start to finish, they were professional, prompt, and thorough. The team showed up on time and completed the job within the timeframe they promised, which I really appreciated. What stood out most was how clearly they explained every step of the process—from the initial inspection to the final cleanup. They took the time to answer my questions and made sure I understood what work was being done and why. Overall, I’m very satisfied with the quality of their work and the level of service I received. I wouldn’t hesitate to recommend them to anyone in need of flat roofing services."

"We have once again reached out to Joe Kim at J & K Home Improvements when we had a new project planned. We were completely satisfied when we replaced our siding and roof with Joe. Now Joe and his professional crew have replaced all our windows . There are never surprises or additions from when the job is quoted. Once again we are totally satisfied and delighted with their work!! It has been a stress free experience each and every time."

Roofing questions, answered by experts

The purchase price of 3-tab shingles is less than that of other material varieties, such as architectural shingles. However, 3-tab shingles generally last far fewer years than even the least expensive architectural ones. Other roofing types, such as metal or clay, also cost more than 3-tab shingles. However, if you plan to stay in your home for many years, the long-term cost of any of these options can compete with 3-tabs because of their longevity.

After you take steps to determine when your roof was last replaced, you may realize you need a new one. Hiring a roofing contractor you can trust involves asking for references and examples of past work. Verify any qualifications the roofer provides. Ask about the expected time to complete the work and about putting guarantees in writing.

Technically speaking, yes, verbal agreements and “handshake deals” can be legally binding contracts that will hold up in court, but the suing party will need to be able to prove that the parties entered into the contract. Even though verbal and handshake deals can be binding, it’s risky to rely on these types of agreements for anything, including roofing projects. Always aim to get your contract in writing, and make sure it includes all terms and that you don’t agree to additional terms that don’t appear in the contract.

The formula for calculating how many squares of roofing you need is pretty easy. Take the total amount of square footage and divide it by 100. With this formula in mind, a 2,000-square-foot roof would require 20 squares of roofing material to adequately cover it.

Skipping the installation of a drip edge or gutter apron can lead to significant water damage. Without this component, water is more likely to seep under roofing materials or leak behind gutters, damaging the fascia, soffits, siding, and even the interior of your home, such as the attic. Over time, this moisture can cause rot, mold, and deterioration. In colder climates, a missing drip edge also increases the risk of ice dams, which can lead to expensive repairs. A drip edge is an essential part of a roof's drainage system, and some local building codes may even require its installation to protect the home from water damage.
