Call (909) 530-1045Note 01What is the best replacement for a flat roof?
When repair is no longer honest, a membrane system detailed properly at its edges and drains, chosen for how the roof is used and how many pipes go through it, and meeting Title 24's cool-roof standard for low-slope roofs.
Note 02How to repair a flat roof without replacing it?
Repair what failed: the seam that opened, the edge where the membrane meets a wall, or the drain that ponds. A low-slope roof rarely fails in the middle, so most repairs are at its edges, and most fall within the estimated $750 to $3,500 California range.
Note 03Does a new flat roof have to be a cool roof?
Under Title 24, low-slope roofs have a cool-roof standard; one published guide gives it as an aged solar reflectance of 0.63 with an emittance of 0.75, or an SRI of 75. The product's rating goes on the quote, beside its fire rating.
