We want to empower you to choose the best roofer for your home or business, and that is why we are answering some of the most common questions we get about Plano roofs!
Do I need to remove my old asphalt roof before having a new one installed?
- Yes. Though it is acceptable to lay a new asphalt roof over an old one, there should never be more than two layers of roof present at one time. When you get beyond this safe zone, the weight can become too much for the underlying structure. Additionally, imperfections in the old roof can come through the new one, wearing it down faster.
My roof has black streaks on it. I want to get rid of them. Do they affect the performance of my roof?
- Your roof has minerals in it that sustain certain types of algae, which tend to show up on shady or north-facing roofs. This algae won’t damage your roof, but we understand that it doesn’t look great. It needs to be gently removed. You can do this by using a pump sprayer to apply a mix of one part bleach to two parts water. (Keep in mind that the bleach will harm any plantings it hits. To avoid this, rinse the plants with clean water before and after treating your roof.) Put a soft window brush on a telescoping extension pole and scrub the roof from a ladder. Don’t get up on the roof.
- You can prevent the algae from returning by getting zinc or copper strips installed on the roof ridge. Rain will wash ions from the metal over the shingles and keep algae away.
