Roofing systems take a beating. After all, they are typically the home’s first line of defense against the elements.
Like all of your home’s elements, roofs will eventually show their age through deterioration. During a recent inspection on Whidbey Island, I came across built-up roof coverings that were cracking—a phenomenon in the industry known as “alligatoring.” As you might guess, this means the roof was starting to resemble reptile skin.
In my report, I recommended further evaluation by a qualified contractor to make repairs as deemed necessary. I also recommended that the clients budget for re-seal coating of the roof coverings.If you have questions or comments about roofing or home inspections in general, tweet me (@AIHomeInspect).
If your membrane roofing system is aging, your roof coverings may experience severe cracking—which may resemble the skin of a reptile.
This condition, known in the home inspection industry as “alligatoring,” is a common occurrence. It happens because of sun damage, ice, and temperature variations—and cracks can get worse if left untreated.
I recently came across built-up flat roof coverings that were alligatoring at a house in Bow, and I recommended the homeowner budget for re-seal coating the roofing. This is a three-step process that involves ridding the surfaces of dust and particles, applying a primer and then finally a coating.
Because this issue is common with membrane roofing systems, homeowners with these systems should inspect their roofs at least twice per year. Apply new coatings as needed, and make sure to repair any blisters that could cause leakage.
