WHY A METAL ROOF EXPANDS AND CONTRACTS?
Metal roofs heat up when the sun rises and passes through the sky. Standing Seam metal roofs are held down with concealed clips and screws that allow the roof panels to move but not put stress on the screws that hold the panel down.
Old style exposed fastener metal roofs do not do that.The panels slowly push and pull on the screws causing the roof to fail prematurely
CAN A METAL ROOF BE INSTALLED ONTO MY EXISTING ROOF?
Standing Seam Metal and Mobile Home Roof Overs CAN be installed directly over your existing roof. Landfills are not polluted by tons of discarded roof materials. The Building Code allows us to re-roof over an existing roof and this practice is done everyday. The fact that a metal roof lasts so long and that it is completely recyclable at the end of its life, makes re-roofing over your existing roof a good idea. It is also a good way to assure that during the installation of the new roof you are protected from stormy weather during construction.
DOES THE COLOR OF THE ROOF MATTER?
A light colored roof has a direct effect, since it reflects solar radiation and reduces air conditioning usage. The indirect effect from a lighter colored roof is that lower temperatures result in reduced ambient air temperatures, which again reduces the overall “heat Island” effect. Dark colored roofs have a higher solar energy absorptive surface and can be 75 to 100 degrees F hotter than ambient air. On the other hand, white reflective roofs are only 15 to 25 degrees F hotter than ambient air. To quantify this reduction, the effect of reducing air temperatures with a city the size of Los Angeles by as little as 3 degrees F would reduce smog by about 10 percent—the same as switching 1 million conventional automobiles from gas to electric power.
I HAVE A FLAT AREA ON MY ROOF. CAN YOU BUILD IT UP AND CREATE MORE OF A PITCH TO MY ROOF?
Yes. If you have a flat (tar & gravel) roof, we can install “tapered” Expanded Polystyrene Foam Insulation (EPS) which allows your roof to be built up and create a pitch (slope) for better water run off. You don’t have the added weight onto your existing roof as you would if you had wood trusses made and installed. You also receive more of an insulation factor creating a greater R factor…which means more energy savings to you.
WILL I BE ABLE TO SEE THE SCREWS THAT FASTEN DOWN THE ROOF PANELS?
On our “Standing Seam” roof system our fasteners and clips are concealed under the metal panels, however, with the “Small Rib” corrugated roof system all fasteners are exposed on the outside.
DO YOU ORDER THE ROOF PANELS OR DO YOU MAKE THEM ON MY JOB SITE?
For the “Standing Seam” roof we run our own roof panels on your job site. We have three computer roll formers that create all panels needed to any length we require. Thus, no seams are created…no matter how long the panels need to be. The “Small Rib” panels are special ordered directly from the manufacturer. We do not roll form this panel.
WILL INSTALLING A METAL ROOF INCREASE THE VALUE OF MY HOME?
According to an article published by the Metal Roofing Association in 2006 “The Residential Cost Handbook”, a reference used by real estate appraisers, it reports that the appraised value of a home will increase by approximately $1.35 per sq. ft. when it has a metal roof. Not only does it add value to your home, a metal roof actually saves you money – on roofing maintenance costs and on your energy bills. Regular asphalt shingle roofs need re-roofing (plus interim maintenance and shingle replacement) anywhere from 5 to 15 years.
DOES A METAL ROOF ATTRACT LIGHTNING?
No. Due to the fact that metal roof systems are not “grounded”, metal roof systems do not “attract” lightning the way you might think. Lightning needs a direct path to the ground and a metal roof system on top of your home does not provide that path. Lightning strikes to metal roofs are extremely rare and usually end up being the result of an unplanned grounded path.
WILL MY ROOF COLOR FADE?
STREAMLINE will only install *Kynar 500® or Hylar 5000® paint system panels on our standing seam metal roofs. This paint finish is a ceramic based paint in which the color of the roof is baked on in a furnace. The Kynar 500® and Hylar 5000® finishes are simply the best paint system available on the market today.
HOW DO METAL ROOFS PERFORM IN WIND?
It has been proven time after time, storm after storm, that Standing Seam metal roofs perform better than any other roofing product. Metal roofs have a very high wind rating which make them a very good candidate for coastal homes. The wind rating for a metal roof system is based upon your site specific geographical area.
HOW DO I ADDRESS MY HOMEOWNERS ASSOCIATION’S QUESTIONS REGARDING METAL ROOFING?
With metal roofing becoming so popular and with so many choices, many Homeowner’s Association’s have been concerned with the types of roofing they will allow in their neighborhoods. STREAMLINE offers a free Power Point Presentation with your Homeowner’s Association officials. We will show them the quality of the metal roof systems available whether it is Standing Seam, Metal Shingles or Metal Tile systems. STREAMLINE can explain the benefits to those who are concerned the most. We have had a great response from the neighborhoods that were most reluctant to allow metal roofing into their area’s.
