In extremely hot weather, start as early as possible and get off the roof before temperatures are too high. Measure the roof accurately and purchase all the materials and tools you think you will need in advance. We will take back unopened coating containers within 30 days of purchase. Nothing is more frustrating than climbing off a roof in the middle of a job to buy more material. Thoroughly and carefully clean and degrease the roof surface.
Roofs collect oils from asphalt, chimneys, and cars plus lots of dirt and dust.
Coatings don't stick well to any of these. Use the cleaning solution like you were cleaning the kitchen floor, letting the chemistry do the work. Use a broom to scrub ponding areas and areas of peeling coatings. Work a section at a time and hose off the dirty water. Sweep away puddles to promote drying.
