While spotting a bit of algae on your roof may not bother you at first glance, it is certainly bothering your roof shingles. The presence of algae can cause decay and shorten the lifespan of your roof’s shingles, which can lead to much bigger problems down the road. While this issue may seem cosmetic at first glance, it goes much deeper than that.

The best type of roof vent depends on the size, type, and construction of your roof as well as the environmental conditions in and around your home. In many cases, an active ventilation system that draws in fresh air and exhausts air out through the attic is the most effective. Active ventilation systems include roof ridge vents with baffles, turbine vents, and soffit vents that are used together with another type of vent.

The most obvious and severe sign of a roof leak is the presence of wet spots on your ceilings, specifically on the top floor of your home. You can also identify a roof leak from your attic if you see sagging insulation or if you notice mold growth or water stains on the rafters or the underside of the roof deck. From the street, look for cracked or missing shingles, moss growth, and shingles that are curling upward, all of which can suggest a leak.

The cost to replace a roof typically ranges from $8,700 to $22,000, with a national average of around $9,200. The total cost depends on the size of your roof and whether you need a full replacement or can simply place new shingles over the old ones. A full replacement, which is necessary if the roof is several decades old or has multiple layers, is more expensive. This process involves tearing off the old roofing materials, inspecting and repairing the underlying structure, and then installing the new roof.
