When you think about cleaning the exterior of your home, chances are good you imagine picking up your yard, raking leaves, removing branches from the grounds and perhaps even cleaning mold from your home’s siding. However, how much attention do you pay to your roof? The roof is the most overlooked part of the home when it comes to cleaning and maintenance, and it really shouldn’t be. Cleaning your roof is vital – here are some of the top reasons why.
Reason #1 – Prevent Algae Buildup
We’ve all seen homes with black stains on the roof. You might think this is caused by water stains, but that’s not really the reason. It’s actually a type of algae. Black algae thrive in the Southeast, particularly in areas like New Orleans, where the warm, moist conditions make it possible for these algae to grow very quickly. Black algae do much more than just create unsightly stains on your roof – it can actually retain moisture and speed up the deterioration of your roof.
Reason #2 – Reduced Potential for Rust
Properly maintained, a metal roof can last a lifetime. However, if you don’t take the time to clean your roof regularly, it can be prone to serious problems. On metal roofs, rust can set in if there is debris present that allows water to collect on your roof, or if damage has occurred that removed the paint/coating on your metal roof panels. Rust eventually leads to serious deterioration, which can compromise not just the roof, but also the interior of your home.
Reason #3 – Reduce Energy Loss
When it comes to homes, the most significant concern for homeowners is the rising cost of electricity. While it might not seem like it, a dirty roof can actually cause energy loss in a variety of ways. For instance, if you have reflective roofing designed to radiate heat and light away from the home (thus keeping the interior cooler and reducing cooling costs), you’ll find that dirt and debris reduces the roof’s ability to its job.
Reason #4 – Moisture Reduction
Finally, moisture is a huge threat to all roofing systems, regardless of construction or material type. Not cleaning your roof regularly can cause debris to build up on top of the roof. Things like limbs, leaves, twigs and other debris act as dams, preventing water from flowing down the roof to the gutters. Over time, this moisture build up can put your entire roofing system and the substructure in danger of rot and mold.
