The type of shingle is taken into account before construction because the material affects the roof pitch and construction method: Some shingles can be installed on lath where others need solid sheathing (sheeting) on the roof deck .
A 35 °C (95 °F) heat reduction was observed on this modified bitumen roof with a white, reflective roof coating. Roof coatings are seamless and when installed correctly, can solve roof leaks on almost any type of roofing material. There are exceptions: "professionals do not recommend using cool coatings over existing shingles.
