Deck Re-Fastening
After the 2004-2005 hurricane seasons the Florida Building Code was changed to help enhance deck fastening and reduce the amount of damage caused by deck failures. It is now required to refasten all wood roof decks when replacing the roof.
*Note: Cut nails and staples carry no weight with the Florida Building Code. In other words, it doesn't matter how many staples or nails are currently holding down your roof decking, the entire roof will need to be completely refastened as if no fasteners are there."
What is 8-6-6?
Let's break down the numbers.
- 8 = The first number describes the type of nail used to fasten the deck. In this case, 8d nails. (Good roofers will use ring-shank nails)
- -6- = The middle number describes the fastening pattern at the roof's perimeter. Roof perimeter is defined as a nine feet zone around the entire perimeter of the roof. This example describes a 6" fastening pattern.
- -6 = The last number describes the fastening pattern in the roof's center, inside the perimeter enhancement zone. In this case the roof's center is being fastened six inches on center, which is code plus. 12" on center would be minimum code.

8-12-12 Minimum Code |

8-6-6 Code Plus |

8-4-4 Code Plus/Highest Wind Protection |
Kelly Roofing Recommendation:
Kelly Roofing's recommendation is to use the 8-6-6 pattern. The difference in uplift resistance between 8-6-6 and 8-4-4 is minimal and insurance companies do not grant any further discounts beyond 8-6-6.

Water Barrier SWB
Avoid a buckled, bumpy - looking roof and reduce blow-off with quality roof deck protection. Superior quality roof deck protection can protect and beautify at the same time!
Kelly Roofing Reccommendation:
Kelly Roofing's recommendation is to use the Fully Adhered, Sealed Fasteners system.
- #30lb Felt Paper, Nailed was outlawed at one time and is now allowed again due to economic reasons. Insurance companies have been known to drop customers who do not have SWB, a Secondary Water Barrier. #30lb. is not considered a SWB.
- Sealed Seams, #30lb. Felt Paper, Nailed was minimum code for two years until economic conditions caused code bodies to revert back to just #30lb, nailed. Although some insurance companies recognize this as a SWB, most do not or give smaller reductions because it is only partial coverage.
- #30lb. felt paper, nailed and a fully adhered underlayment passes code, but does not provide any insurance discounts since the plywood is not "sealed". It’s added expense with little benefit.
- Fully Adhered, Sealed Fasteners provides the maximum insurance discount for providing a SWB. In high wind events it actually helps to hold the entire deck together to prevent water intrusion and deck failure. The most common question is, "If the material is adhered directly to the roof deck, what happens when I need to replace my roof again in the future?" The answer is, "Once a SWB is installed, it never needs to be replaced and will continue to perform for the life of the building." If a leak does develop and decking materials need replacement, each individual plywood sheet is cut out and replaced, just as they are now. See below for a sample savings chart and downloads of material brochures.
Quality Roof Deck Protection
-
Prevents wind-driven rain…
(or water from other sources) from infiltrating under your shingles
and causing damage to your roof structure or the inside of your home.
-
Provides an extra layer of protection…
between your shingles and your roof deck.
-
Lays flatter…
and will not buckle when installed.
-
Helps reduce blow-off…
by allowing your shingles to lay flatter and more uniformly.
-
The Kelly "Code-Plus" Difference…
Kelly Roofing uses a fully self-adhered modified underlayment directly to the entire deck as a "code-plus" designed roof system component, which will qualify for substantial insurance reductions and act as a secondary water barrier in case of main roof system blow-off and/or damage.
Advantages of Peel-and-Stick Underlayments
All underlayments are manufactured with ADESO® technology, incorporating an APP
compound on top and self-adhesive compound on the bottom. The underlayment we use offers
advantageous characteristics including split release backing film for easy positioning of sheets, and allows for
steep roofing to be easier, cleaner, faster, and more reliable than ever.

Wind Resistant Roofs
Metal is synonymous with strength and toughness. But as a roofing material, strength is only one of the advantages of metal roofing. Metal roofing costs are surprisingly affordable due to the fact that a metal roof is a permanent one; the life-cycle costs are substantially lower than conventional roofing materials. For aesthetics, metal roofing comes in a variety of styles and colors to fit your personal preference.
A high-quality metal roof is solid protection for your home, and all the important things in it. After all, a metal roof will withstand hail, high winds and wildfires. A metal roof adds value to your home - while likely saving you money on energy costs and insurance premiums. Plus, a metal roof is built to endure for decades, so it's likely the last roof you'll ever buy. Learn more about the Kelly Roofing Metal Roof System so you can begin taking care of the things you care most about.

- Bright light regulates the suprachiasmatic nucleus clock, which is known by most as our bodies internal clock. This clock keeps our bodies set to the correct time.
- Electric lighting accounts for one-fifth of the total electrical energy used in the U.S.
- Students perform significantly better in environments that are lit with natural, rather than artificial light. The study, one of the largest of its kind, tracked test scores for 22,000 students in California, Colorado and Washington. Researchers report that learning rates were 26 percent higher in reading and 20 percent higher in math in rooms with the most natural light.

- 20% of our population suffer varying degrees of Seasonal Affective Disorder (SAD). Individuals with SAD may experience emotional depression, a drop in physical energy, an increased appetite, and an increased need for sleep. Lack of sufficient daylight is directly linked to SAD.
- As you age, the lenses of your eyes thicken and the pupils shrink in size, causing your eye to adapt much more slowly to changing light conditions. Researchers McFarland and Fisher reported that to accommodate the adaptation of the aging eye, the amount of light required for visual acuity doubled for each 13 years after the age of 20. It is clear that softer, natural light equals better vision.
- American homeowners said if they had a choice of accessories for the ultimate dream bathroom, No. 1 on the list would be a skylight to bathe the bathroom with more natural light.
- That sunlight heals a variety of skin problems. A bit of sun, 15 minutes or less on a regular basis, may help control eczema, acne, psoriasis and even dandruff. UV rays interfere with the proliferation of abnormal skin cells that trigger eczema and psoriasis. Researchers are working to pinpoint more precisely how UV rays affect the skin's immune system.
- That American companies lose as much as $22.8 billion each year to lost productivity resulting from poor ventilation.

- That studies comparing natural day lighting to conventional electric lighting show that students who attended elementary schools where natural day lighting is used have better attendance, better dental records and grew more - 3/4” more over a 2 year period.
- That people need vitamin D for calcium to be absorbed by the body to strengthen teeth and bones and other tissue to maintain a healthy skeleton throughout life. Two sources of vitamin D are diet and sunlight. In healthy human bodies, 80% of vitamin D is developed through exposure to natural light. A vitamin D deficiency could result in the brittle-bone disease osteoporosis, which affects mostly women. Skylights and milk - a winning combination!
- That "Sick House" symptoms develop because the house literally can't breathe. As a result, it gets congested with internal pollutants or Volatile Organic Compounds (VOCs). Common sources of pollutants (VOCs) in the home are adhesives, upholstery, carpets, furnace exhausts, fireplaces, pressed wood cabinets & cupboards. VELUX venting skylights allow your house to breath!
- Often described as that pleasant, "new smell," VOCs can be harmful. Short-term exposure to VOCs can cause headaches, nausea and irritate eyes, throat and nose. New houses are insulated and sealed so well that no fresh air enters in. Moisture builds up but can't escape and that makes a perfect breeding ground for mold.
