No matter whether you do it your self or simply call in a professional, these are the key objects that should be addressed throughout an attic inspection.



Suitable ventilation is important, and just one of the very first factors looked at in an attic inspection. Cooper says attics will have to be correctly ventilated so the roof and attic can “breathe.”

“Signals of inadequate air flow involve, mold, rusted nails and condensation — usually in the winter — on sheathing,” Cooper states. “In the warmth of the summer months, you want an attic temperature that is cooler than 110 levels F.”

Pro Idea: The most efficient way to increase air flow is with soffit and ridge vents, Cooper states. The soffit/ridge blend normally takes air from the lowest issue of the attic (soffit) and exhausts it by the best stage/peak (ridge) of the attic.


Attic insulation performs a massive portion in regulating the all round temperature of your property. A drafty upstairs, specifically at the entrance to the attic, can indicate a need for extra insulation.

During an inspection, Cooper would also use a thermal imaging digicam to detect a change in temperature. He checks for enough insulation depth and any spots wherever insulation is lacking. Insulation can settle in older households, he states, and so it may be required to increase far more insulation.

Professional Tip: A swift way to decide if you need a lot more insulation is to glance across the span of your attic. If your insulation is just level with or below your flooring joists, you should really insert much more.

A leaking roof is evidenced by h2o stains, rot or mold in the attic, in particular on the sheathing. However, leaks you should not normally come from a hole in the roof or weakened shingles, Cooper suggests.

“Leaks in the attic are most typical close to vents, plumbing stacks, radon techniques and even the chimney,” he says. “Around time, the tar made use of to seal the chimney flashing can deteriorate, causing leaks into the attic.”

It really is doable to maintenance any small leaks on your have, in particular if you have a a person-tale, reduced-slope roof. On the other hand, Cooper notes that most leaks will require anyone to get on the roof. In that case, he advises possessing a specialist repair service any major challenges.


Droppings, nests, leaves, acorns and hurt to insulation are indicative of a pest trouble. “Vermin can simply appear in by means of any gaps in the soffit. An attic inspection will enable detect any entryways for pests,” Cooper states.

Professional Idea: There are rigid procedures in several states pertaining to the removal of sure pests, like bats. They are unable to be removed with poison and are secured during specified periods of the calendar year. Installing exclusion doorways will permit bats previously in the attic to escape, but will not let them back again in. Trapping and removing rodents, and then sealing off any entryways, is the ideal way to remove and stop rodents from returning. More substantial pests like raccoons or big snakes really should be dealt with by specialists.

Exhaust Ducts and Vent Stacks

All exhaust ducts and vent stacks ought to continue via the roof to the outdoors, but that isn’t really constantly the situation. Cooper states he typically sees lavatory supporters vented instantly into the attic.

“Bathroom vent admirers have to vent to the exterior of the household, no matter if it can be via the roof or an exterior wall,” he claims. “Venting dampness into the attic will generate condensation on the roof framing members and insulation. In a poorly vented attic, this can also lead to mould development.”

The fix? Cooper recommends extending vents to terminate outside the house the dwelling or putting in a vent hood on the roof.

When inspecting ducts and pipes that are vented to the exterior of the residence, make sure they’re not cracked, loose or harmed. Cooper also advises versus just about anything leaning on the pipe or ducts.
