Do you know the dangers of heat damage to asphalt shingles?
Smoke and heat from fires are never good for an asphalt roof, but how can you tell whether a roof needs to be replaced after exposure to a fire? What if the fire occurred at a neighboring home, or a forest fire or factory fire near your home?
Our partners at GAF, the premium shingle manufacturer used by Feazel in our asphalt roofing projects, recommend a close inspection of asphalt shingles if there has been a fire nearby.
The intense heat from a house fire or a nearby fire can cause heat damage to asphalt shingles that is noticeable in the following ways:
- Melted or runny asphalt
- Distortion in the top coating of the shingle
- Blistering due to heat or burning embers
- Singed shingles
Professional Inspection for Heat Damage
Because the damage to the shingles may be subtle, and because of the danger of climbing onto a roof that may be damaged, it’s a good idea to have a professional inspect the roof.

While it may be tempting to breathe a sigh of relief when a home near you experiences a fire, but it doesn’t spread to your home, the better course of action is to call for an inspection by a professional. If the asphalt
shingles are compromised, there could also be damage to the roof decking and substrate.
According to GAF, most damage that occurs from a fire in close proximity will be visible to the eye. However, it is also recommended to have a follow-up inspection after a few weeks to insure deterioration did not occur later.
Non-fire Heat Damage
Fires are dramatic, and most homeowners would think to check for damage after a nearby fire. But there is another kind of heat damage to roofs that is more insidious: the slow, invisible toll from inadequate ventilation. A poorly ventilated roof can cause slow but serious damage to the average asphalt roof. For more on preventing such damage, read this related article.
