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 FAQs, answered by experts

A cool roof is any heat-reflecting roof that rejects solar energy more efficiently than traditional roofing (staying about 50 degrees cooler). Thanks to this ability, a cool roof will make your home cooler on a hot, sunny day. Cool roofs come in a variety of materials, including asphalt, wood, or polymer shingles, clay or concrete tiles, metal, and more.

If your roof has a vapor barrier, you will need approximately one square foot of roof vent for every 300 square feet of ceiling space. If there is no vapor barrier, the roof should have one square foot of roof vent for every 150 square feet of ceiling space. If you are not comfortable making this determination, a local roofing professional can help.

Sometimes chimney caps blow off during storms or fall off after rusting away. While this typically won’t cause structural damage, failing to replace a chimney cap can. A chimney cap prevents moisture, animals, and debris from entering your chimney, all of which can cause serious problems, such as damage to the masonry or blockages in the flue.

Generally, roof flashing is installed under the shingles to create a watertight seal and prevent moisture from seeping in and causing damage. However, the exact placement can depend on the type of flashing. For instance, with step flashing, the shingles and flashing overlap each other, meaning the flashing is technically both over and under the shingles. Flashing also typically goes beneath the house siding and is often not visible from the ground.

Gable vents are more common in older homes built before the 1970s. Homes built after this era use ridge vents or soffits, but you can sometimes find homes with both gable and ridge vents. Gable vents can have a purely aesthetic purpose, while ridge vents hide in the roof shingles so air can flow under the roof while keeping the attic dry.
