Small jobs welcome

Hello, my name is Josh. Im 20 years old, I have a strong back, and just enough experience to help you accomplish what you might not be able to. Whether its because you are inexperienced/unable, too busy, lack the proper tools/equipment, or simply because you don't want to (trust me, im the last one to judge). I have professional experience in construction, minor landscaping, and instalation. This includes concrete flatwork, grading (gravel, soild, sand, ect), lawn/garden maintenance, minor carpentry, mounting/instalation. I can paint, clean, im not afraid to use a ladder or get on your roof. I have a pickup truck if you need to move furniture or other large objects, and the capability to load it for you. Bottom line is that what ever task you cant acomplish on your own, I can handle, no questions asked, no crazy 2 hour minimums or really any bs in general. If youve ever thought "I need a guy for this" Josh is your man

"When my roof sustained damage from straight line wind in June of 2023, I had no idea who I was going to get to repair it. A person from Quality Roofing Pro stopped and we talked for a while. Without being pushy at all (which I liked) Tony left me some paperwork on the company. I took a few days to make my decision and I have to say, I am so glad I had them do my roof. My shingles were delivered on a Friday. The crew was here on Monday morning at 7am and tore off the old roof and completely got the new roof on by 8pm. They were very particular about cleanup and even used a magnet to pick up any stray nails from the yard. I am extremely happy with their work and would use them again in a heartbeat but sure hope I don’t have to!! I highly recommend them. Thank you Tony and everyone at QRP for making a stressful event so much easier."

Roofing FAQs, answered by experts

In general, you should consider replacing your roof if more than 30% of it is damaged. This includes several missing shingles, large spots of granule loss, extreme curling or cracking, structural damage to the roof's decking, or multiple areas of leaks. All of these issues could indicate compromised structural integrity that requires roof replacement.

Building code allows 24-inch on-center spacing for roof trusses. However, you can install them on 12- or 16-inch centers to handle large loads or other exceptional circumstances. In cases such as covering a wide span or supporting alternative roofing materials, where a structural engineer needs to evaluate or create a design for your trusses, the plans will indicate the spacing. 

The material and frequency of maintenance are the biggest factors for determining the longevity of your shingles, not the color. For instance, luxury asphalt shingles can last 30 years or even longer, while slate tiles have an impressive lifespan ranging from 75 to 100 years. That said, lighter-colored shingles can help reduce your energy costs in the summertime.

The terms “roof shingles” and “roof tiles” are sometimes used interchangeably, but the term “shingles” most often refers to asphalt, rubber, metal, or slate shingles, and the term “tiles” normally means they’re made from clay or concrete. In all cases, shingles are small, rectangular components that a roofer layers in an overlapping pattern to protect the structure underneath from the elements.

Shingle roofing can last anywhere from 15 to 50 years, depending on the type and quality of shingle, your local climate, and how well you maintain your roof. If you live in an area that sees extreme weather, like strong winds, hail storms, or hurricanes, the average life span of a shingle roof will often be on the shorter end, especially if you choose a more affordable roof shingle that isn’t designed to persist through extreme weather.
