cool roof in hot climates there are few green building choices smarter than a cool roof in hot climates. the best way to beat the heat is to not absorb it in the first place. use light color metal roof with overhangs to shade the walls on the south and west sides. i can tell you that my experience is that any metal roof is cooler than asphalt shingles.
a corrugated tin roof is not hard to work with. the ripples or corrugations stiffen the tin. if you work with flat tin from a roll, it's nearly impossible to hold strht. it's as unruly as a piece of wet spaghetti. corrugated tin roofing is often the material of choice for beginners as it's easy to attach to a wood-framed roof.
a cool roof is a roof designed to maintain a lower surface temperature in bright sunshine than a traditional roof source: department of energy . the surface of a cool roof reflects more sunlight and releases more heat than a so-called hot or dark roof.
need help cooling a sunroom. swede27410. june 7, 2013. i bet your porch is on the western exposure. late day exposure to the setting sun. that is very important to allow for good air flow and a whirly bird in the roof will suck out hot air too. i don't know what size ceiling fan you have, but for your sized room you would need a large
pvc roofing. the advantage of the pvc/polycarbonate roofing is the translucency of the panels.they allow daylight to enter through them. if cost is a factor, pvc is a cheaper alternative to sheet metal. pvc will block out the heat from the sun much more effectively than sheet metal, which will act like a radiator.
metal roofs, such as this new copper one in loxahatchee, florida, can get very hot on sunny days. to keep them cool and extend their life, scientists have created a new paint made of glass.
some years ago we had a porch roof on the north side of our house we roofed with a nice green metal roof. what a surprise mistake . after it was installed, the ambient reflected light tinged the 2nd floor rooms above the roof in a pale green color. very noticeable, very objectionable. we had to paint it a neutral cream/tan/grey.

our upstairs sleeping porch was once just a porch, so it has no attic space. after tearing down the old dropped ceiling and pulled out the old insulation, all thats left between our heads and the elements are the joists, beadboard roof sheathing, 2 foam insulation, and the roof membrane.
this type of roof panel is corrugated to resemble a metal roof, but is much lighter weight. the foam backing on the panels helps to insulate the building, while the protective coating on the panels deflects uv light. the result is a roof that helps keep your home more even in temperature year round, resisting heat transfer in both directions.
one of the reasons that tin roofs heat up so much is that the heat has nowhere to go. a closed-in roof system is just like an oven. when the sun shines on the metal, the heat is absorbed into it. this heat is then radiated through the wood underneath and into the attic, or directly into the home.
installing translucent plastic corrugated roof panels contract up to three times less than pvc and polycarbonate panels which provides for a more stable product in both hot and cold conditions. panels install much like corrugated metal and provide the added benefit of light transmission.
installing a metal porch roof can possibly save you money on heating and cooling bills. the mra reports a potential 40% savings in energy costs during the summer months dependent upon your specific geographical area by installing reflective metal roofing.

corrugated tin roofing is often the material of choice for beginners as it's easy to attach to a wood-framed roof. it's also not always necessary to solder any of the seams, as you can often achieve a weathertight roof by overlapping the corrugated pieces of metal. installing a tin roof like the one on my older home is not a task for a beginner.
in hot climates cool roof choices almost always make sense when there is no cost penalty, i.e. you choose white metal roofing over gray, green or brown metal roofing, etc. in the vast majority of homes the rafters attach to the top plates and the top plates are insulated from the interrior by a little sheetrock.
lets take a look at why metal roofing is popular in hot climates, as well as special considerations to keep in mind when thinking about a metal roof in a hot climate. durability. the roof is not a pretty place to be. in all climates, it is subject to severe winds and punishing rains. but in hot climates, it also has to endure extreme heat and great amounts of sunlight. heat and sun cause most roofing materials to break down rapidly. they dry out, crack, curl, and disintegrate.
you'd have to seal them to keep out moisture, which might not be possible. a house roof needs to breathe to handle moisture from inside and out. they can get condensation on the underside. attics needs to be vented to keep the heat from getting too hot, they would let in way more heat than a conventional roof.
plastic corrugated panels are made from fiberglass reinforced resins or polycarbonate. fiberglass is not flammable, that's why its used for insulation. but as the panels break down over time, the fiberglass fibers are exposed, released, and can be inhaled. not good polycarbonate panels are solid, uv safe, and do not break down.
renshade is the best way to keep your pergola cool, reflecting the sun away from it's clear plastic roofing while still letting in about 15% of the light.
