Cool Roof


A cool roof is a roof­ing sys­tem that deliv­ers high­er solar reflectance (the abil­i­ty to reflect the vis­i­ble, infrared and ultra­vi­o­let wave­lengths of the sun, reduc­ing heat trans­fer to the build­ing) and high­er ther­mal emit­tance (the abil­i­ty to radi­ate absorbed, or non-reflect­ed solar ener­gy) than stan­dard designed roof­ing prod­ucts.  His­tor­i­cal­ly, cool roofs have been either white or some oth­er lighter shade col­or. How­ev­er, that dynam­ic has changed in recent years with the devel­op­ment of res­i­den­tial cool roof prod­ucts like Land­mark Solaris™ and Pres­i­den­tial Solaris™ from Cer­tain­Teed that can achieve Ener­gyS­tar® qual­i­fied lev­els of solar reflec­tiv­i­ty even in dark, rich hues.

Cool roofs can also enhance roof dura­bil­i­ty and reduce both build­ing cool­ing loads and the urban heat island effect.

Most of the roofs in the world (includ­ing over 90% of the roofs in the Unit­ed States) are dark-col­ored. In the heat of the full sun, the sur­face of a black roof can increase in tem­per­a­ture by more than 100 °F over the ambi­ent tem­per­a­ture, reach­ing tem­per­a­tures up to 190 °F.  This increase in sur­face tem­per­a­ture can con­tribute to:


  • Increased cool­ing ener­gy use and high­er util­i­ty bills;
  • Reduced indoor com­fort;
  • Accel­er­at­ed dete­ri­o­ra­tion of roof­ing mate­ri­als, increased roof main­te­nance costs, and high lev­els of roof­ing waste sent to land­fills.
  • High­er peak elec­tric­i­ty demand (the max­i­mum ener­gy load an elec­tric util­i­ty expe­ri­ences to sup­ply cus­tomers instan­ta­neous­ly, gen­er­al­ly expe­ri­enced in sum­mer late after­noons as busi­ness­es and res­i­dences turn up their air con­di­tion­ers), raised elec­tric­i­ty pro­duc­tion costs, and a poten­tial­ly over­bur­dened pow­er grid;
  • Increased air pol­lu­tion due to the inten­si­fi­ca­tion of the “heat island effect”

Any build­ing with a dark col­ored roof will con­sume more ener­gy for air con­di­tion­ing than a “cool­er” build­ing – a strain on both oper­at­ing costs and the elec­tric pow­er grid. Cool roof prod­ucts such as Land­mark Solaris shin­gles, Pres­i­den­tial Solaris shin­gles, and Cool Star com­mer­cial cool roof­ing prod­ucts from Cer­tain­Teed offer both imme­di­ate and long-term sav­ings in build­ing ener­gy costs. The EPA reports that cool roofs can:


  • Reduce ener­gy use: A cool roof trans­fers less heat to the build­ing below, so the build­ing stays cool­er and uses less ener­gy for air con­di­tion­ing.
  • Reduce air pol­lu­tion and green­house gas emis­sions: By low­er­ing ener­gy use, cool roofs decrease the pro­duc­tion of asso­ci­at­ed air pol­lu­tion and green­house gas emis­sions.
  • Improve human health and com­fort: Cool roofs can reduce air tem­per­a­tures inside build­ings with and with­out air con­di­tion­ing, help­ing to pre­vent heat-relat­ed ill­ness­es and deaths.

CertainTeed’s Land­mark Solaris, Land­mark Solaris Gold, Land­mark Solaris Plat­inum and Pres­i­den­tial Solaris shin­gles are prime exam­ples of res­i­den­tial cool roof­ing prod­ucts that pro­vide an enhanced aes­thet­ic appeal. And for a shin­gle that is both ener­gy effi­cient and impact resis­tant, try Land­mark Solaris IR.



Mis­sion State­ment: Our objec­tive is to pro­vide our cus­tomers with the high­est qual­i­ty roof­ing, sid­ing, win­dows, gut­ters, and entry door work in the North­ern Vir­ginia & Mary­land areas by offer­ing expe­ri­ence, effi­cien­cy, high qual­i­ty prod­ucts, cus­tomized projects, and the best cus­tomer ser­vice. Our goal is 100% cus­tomer sat­is­fac­tion.

Vision State­ment: Our vision is to be the best roof­ing, sid­ing, win­dows, gut­ters, and entry door replace­ment com­pa­ny in the North­ern Vir­ginia and Mary­land area. Our vision is cen­tered on the cus­tomers’ needs and vision of their home.

Core Val­ues: Our moti­va­tion in each project is direct­ed from our core val­ues. Each core val­ue is cen­tered on the cus­tomer and includes: old time val­ues, con­cern for the cus­tomer, offer­ing the cus­tomer the best prod­ucts, and giv­ing the cus­tomer the best price for the high qual­i­ty prod­ucts.
