Best chimney inspectors near Jesup, IA

Walking on an asbestos roof can pose a risk. Asbestos roofing materials can become brittle over time, increasing the chances of them breaking or releasing fibers when stepped on. Additionally, walking on an asbestos roof without proper precautions can cause further damage to the material. If possible, avoid touching an asbestos roof in any way and consult with a professional about removing and replacing the roof. 

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.

Common issues discovered during a chimney inspection or cleaning include creosote buildup, cracked liners, structural degeneration or masonry degradation, and obstructions such as blocked flues or animal nests. These issues are potential safety hazards that can lead to combustion problems or poor air quality if not addressed.

While you can technically install new roof sheathing over an old layer, it is generally not recommended for several reasons. Installing new sheathing over old can trap moisture, which may lead to future problems, especially in humid climates. It also adds significant weight to the roof structure and prevents you from inspecting the original sheathing for rot, mold, or other damage.

However, in some cases, if the old sheathing has been thoroughly inspected and is in excellent condition with no signs of rotting, warping, or damage, a roofer may install new sheathing over it to add strength and stability. Despite this, the more common and recommended practice is to remove the old roof sheathing entirely before installing a new layer, as removing it is not a difficult task.
