"This company was so extremely conscientious in how they did their work. They went into some areas that would be so difficult to clean, and they did the job really well. Additionally, they did something I wasn't expecting...they thoroughly washed the screens that were in my windows, meticulously taking each individual screen out and power washing each screen in addition to making sure the window was spotless, taking care of washing windows that were on the second or third level. I was so impressed with their hard work, punctuality, and efficiency in the work they did. I would recommend at the lux janitorial services to anyone who needs a tremendous job on windows done with kindness and professionalism."

They have done our garage roof, the main roof on our house, they have put in new roof for my town home, and all looks beautiful. The team is very prompt response. The crew is very friendly and professional. I will use them again for future needs."

Roofing FAQs, answered by experts

Many insurance policies will not cover a roof with two layers of shingles. An additional layer of shingles increases the risk of various kinds of damage, and insurers typically won’t pay claims on a roof with an overlay. Adding a layer of shingles may even jeopardize your insurance coverage entirely, so check your policy to ensure you stay within coverage guidelines. 

In some cases, yes, you can put a second roof layer over architectural shingles, but it depends on your home’s structural stability and the local building codes where you live. Architectural shingles are thicker and heavier than standard asphalt shingles, so you may need structural reinforcement or a structural engineer’s inspection before proceeding. Additionally, some building departments don’t allow for two roof layers, regardless of the roof type. You should ask a professional if ripping the old roof off before installing the new one is the best option for you.

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.

A spray foam roof lasts 20 to 30 years if installed and maintained correctly. Spray foam roofs should be recoated every 10 to 15 years to maintain the UV protection and waterproof surface of the foam material. The longevity of spray foam roofing will depend on the thickness and density of the foam, the protective coating, and how well it’s maintained.

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.
