SkyBlue Builders Inc., started in 2001 focusing on Residential New Construction. After gaining all this experience the family business decided to focus on Siding, Windows, Doors, Seismic Retrofits, ADU's, Decks, Painting, Complete Interior Remodeling, & General Construction. We service Residential & Commercial clients.

"SkyBlue Builders Performs Quality Work SkyBlue Builders is a Five Star High Quality Siding Construction Company, and I recommend them. My thirty-year- old home is in a rural environment. with a humid atmosphere. The siding on my home was worn by the salt air and moisture and needed replacement from the eaves all the way to the foundation. I chose SkyBlue for three main reasons: 1. Siding is all they do, and they have specialized in it for 19 years. 2. They are rated A+ by the BBB and have had no complaints regarding their work. 3. I viewed online photos of their previous jobs and was impressed by the quality of their work. My experience with SkyBlue was positive from beginning to end. Every day they showed up at 8 A.M. and worked until 4 P.M. when they began cleanup. Every day they put away their tools and cleaned up the work area. At the end of every day they made sure that my driveway was clear, so I could pull my car out of the garage. The workers were always polite and cooperative and responded positively to homeowner concerns. Here are some examples of their work: 1. SkyBlue provided protection against animals. Our rural community has many wild creatures nearby: Bats, coyotes, skunks. raccoons, opossums, mice, and gophers abound, These animals are always in search of a warm and dry haven such as a basement. Over the years, invading animals chewed the wiring of my HVAC dampers, ruining the home heating and cooling controls. I spent thousands to repair the damage. I reported this history to SkyBlue. They replaced the old substandard and ineffective basement vents with quality new vents. They were also careful not to leave any vent opening exposed during the repair. SkyBlue also replaced my costly, old, substandard roof eave “chicken wire bat control,” installed by three separate “bat experts.” SkyBlue installed new, high tech, high quality solid construction in the space between the fascia and siding. Now there is no space for the bats to occupy. 2. SkyBlue used quality materials and did quality work: SkyBlue installed Kelleher Double Pre-Primed Siding so that both sides of the siding and trim are pre-primed with two coats of prime and thus are well protected. SkyBlue reset every single nail in the new siding and trim, and then caulked all holes. Finally, they sanded the caulking, effectively hiding every nail. Looking at my house, you can’t see any joints where two siding boards come together. You cannot see any nails. What a refreshing improvement from the original construction ! SkyBlue then applied two color coats of High Quality Sherman Williams Paint, for a total of four coats of paint. The result is spectacular. To see their work for yourselves, go online and look at photos of their previous jobs. 3. SkyBlue found and repaired old wood damage and previous poor construction. The repair work is better than the original construction. Their workers are experienced, friendly, and will listen to your concerns. The people who hire SkyBlue are people who want quality construction with attention to detail, and a beautiful result."

Roofing questions, answered by experts

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.

DIY is not recommended due to safety and expertise requirements. Professional installation ensures proper alignment and sealing.

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.

Underlayment exists under your tile roof. It helps protect your home by acting as a secondary water barrier. Often, when roof tiles fall off, underlayment that's in good condition can temporarily keep water from getting into the home. However, immediate replacement of missing tiles is crucial to avoid additional roof damage. 

Depending on the materials and conditions of your house, flashing has a life span of 15 to 50 years. To ensure its longevity, schedule an inspection for your chimney and roof each year. A pro can quickly assess its condition and recommend repairs.
