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.
