Chimneys are vital to building structures, particularly throughout cold winter months. They help keep the noxious gases created by a fireplace from coming into the residence, keeping the inside air clean and safe to breathe. Although the chimney is a completely separate structure from the roof, it is very important to not neglect its regular inspection and maintenance, as it could easily become a source of harmful carbon monoxide poisoning.
Why Evaluate?
There are lots of reasons to inspect the chimney. The top end of the structure is basically left open to various outdoor elements and the opposite end is constantly exposed to extreme heat, which makes the whole framework more susceptible to damage. home inspections prices
The most frequent type of problem to occur is cracks, with numerous assorted causation factors. Thermal fatigue is one of the most common occurrences. The contrast between inside and outside temperatures can cause the chimney to crack, establishing a path for leaks.
The flashing that connects the roof and the chimney can also loosen from thermal expansion of the roofing layers. Even strong winds can cause the flashing to work loose, rendering it ineffective in the protection it needs to afford. This particular situation could lead to leaks around the exterior part of the structure, allowing water to absorb into the underlying roofing layers.
Chimneys are most often used throughout the cold winter season; however, many things can occur in the interim. A feathered creature might nest inside the flue during the summer months, causing a blockage. Soot could add up over many years of use and eventually narrow the flue passageway, making it ineffective in exhausting dangerous gases.
When to Inspect
Most chimneys are made from brick masonry and occasionally cement; a handful are made from prefabricated steel. Irrespective of what material have been used, it is essential to conduct examinations as follows:
Every year
A yearly evaluation really should be done several months before the winter season beginning to ensure any repairs could be made with ample time remaining prior to when the winter season actually begins. During the periods when the chimney is not being used, dirt could have accumulated. Birds have a practice of nesting in the flue, which might cause a partial or even complete clog. Damage may also have taken place from previous winter’s usage and necessitate repairs. An annual examination can help mitigate most of these potential problems.
Seismic Events
Immediately after an earthquake, it is essential to investigate the chimney for cracks. Even the steel type of chimney ought to be examined, as it could also be damaged.
Violent Storms
Intense wind and hail can certainly wreck masonry and cause openings in the flashing. Make sure to examine the outside of the chimney after every single storm to check for any brand new damage.
Leaking
When evidence of a leak appears on a ceiling, the chimney needs to be scrutinized as well as the roof because both can be the source of leaks. A crack might have occurred or the flashing might have come loose, letting water to soak through into the underlying material.
Essential Safety Tips
When climbing onto a roof, there is a real risk of falling. When completing a chimney inspection, it would be better to do so during clear weather when the roof is not so perilous. Wearing rubber-soled shoes for more traction would be a good idea as well as having a spotter nearby who could respond promptly in the event of a fall. It would also be a great safety precaution to use a safety line when getting up on top of the roof. If the pitch of the roof is too steep or too high, it’s better to leave the task to a professional contractor.
Chimneys are a vital part of a home and should never ever be neglected. home inspection checklist
