Hello my names Christopher i am 23 tired of working for a boss that doesnt understand what goes into things when we install. I have finally turned over a new leaf and wanted to start dping things on my own. I have worked for a few different landscaping companys, i have done some demo work for family and friends, i also worked at thrasher for ahile working my way up to team lead. I just had a baby last year on December and i want to be able to see her grow! Thats why im here to get jobs that i want. I dont wanna work for a boss who has no idea how the stuff i install goes in. I want to be thats hands on boss that is for the customer. Tired of meeting quotas. I want to love what i do for work and believe you me i love getting dirty and getting the job done. I am only 23 but i am very hard wokring. Not affriad to try something new or get dirty! If you have any jobs small or big just let me know.

Roofing questions, answered by experts

The green coloration that develops on copper roofs is called a “patina,” and it’s a result of mild oxidation on the surface. The oxidation process is not harmful to your roof. In fact, the surface corrosion acts as a protective layer and won’t spread to the core of your copper roof materials. The discoloration will progress much more quickly in damp or humid climates than it will in dry climates. If you don’t like the green color, you can seal your roof to preserve the shiny, rose-gold look.

The warranty for algae-resistant shingles varies by manufacturer, but the industry standard is 25 years for overall shingle durability and lifespan and between 10 and 15 years for algae resistance. Some products come with longer warranties for discoloration of up to 30 years. Check warranty coverage for the shingle and algae protection before deciding on a roofing product.

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.

As long as your solar panels are properly installed without damage to your roof, they will not shorten the roof’s life span. Solar panels can act as a cover or barrier to your roof and help block external elements, such as debris, heat, and UV rays. Reduced exposure to the weather can extend your roof’s life.

A roof pitch multiplier is an accurate way to calculate roof square footage, and it’s handy for purchasing the correct amount of materials. To determine your roof pitch multiplier, you'll need to calculate the roof slope, square it, and add it to 144. Next, find the square root of the total and divide it by 12. The answer is your roof pitch multiplier. Once you know the roof pitch multiplier, multiply it by the total square feet of your building to determine the total roof surface area.
