Chimneys are vital to building structures, especially during cold winter months. They prevent the noxious fumes produced by a fireplace from coming into the residence, keeping the inside air clean and safe to breathe. While the chimney is a totally separate structure from the roof, it is important to not neglect its regular examination and maintenance, as it could easily become a source of hazardous carbon monoxide contamination.

Why Evaluate?

There are many reasons to examine the chimney. The top end of the chimney is essentially left open to different outdoor elements and the opposite end is constantly exposed to extraordinary heat, which makes the whole entire framework more susceptible to harm.

The most typical type of damage to happen 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 work loose from thermal expansion of the roofing layers. Even heavy winds can allow the flashing to loosen, rendering it ineffective in the protection it should afford. This could result in leaks around the exterior portion of the structure, enabling water to soak into the underlying roofing layers.

Chimneys are used most frequently throughout the cold winter season; having said that, lots of things can occur in the meantime. A feathered creature could nest inside the chimney flue during the summer months, producing an obstruction. Soot could accumulate over years of use and eventually narrow the passageway, making it ineffective in exhausting hazardous gases. read

When to Examine

Most chimneys are constructed from brick masonry and sometimes cement; a few are made from prefabricated steel. Regardless of what material have been utilized, it is essential to conduct checkups as follows:

Every year

A yearly examination should be done several months prior to the winter season beginning to ensure that any repairs could be made with adequate time remaining prior to when the winter season actually starts. During the periods when the chimney is not in use, dirt could possibly have accumulated. Birds have a habit of nesting in the chimney flue, which may cause a partial or even complete obstruction. Damage may also have developed from prior winter's usage and require repair work. An annual checkup can help mitigate most of these problems.

Seismic Events

Immediately after an earthquake, it is important to investigate the chimney for cracks. Even the steel variety needs to be examined, as it could also be damaged.

Violent Storms

Intense wind and hail can harm masonry and cause openings in the flashing. Be sure to evaluate the exterior of the chimney after every single storm to check for any brand new damage.

Leaking

When proof of a leak turns up on a ceiling, the chimney needs to be evaluated along with the roof because either can be the cause of leaks. A crack might have occurred or the flashing might have loosened, permitting water to seep through into the underlying material.

Essential Safety Tips

When getting up on a roof, there is a real risk of falling. When completing a chimney evaluation, it would be preferable to do so during clear weather when the roof is not so perilous. Donning rubber-soled shoes for extra traction would be prudent as well as having a spotter nearby who could take action promptly in case of a fall. It would also be a great safety precaution to secure a safety line when getting up on top of the structure. If the angle of the roof is really steep or too high, it is much better to leave the task to a professional contractor.

Chimneys are a vital part of a home and should never ever be ignored. ct home inspectors
