Who Do I Call – My Roofer or HVAC Company?

November 16th, 2021

Clanging noises, stuffy attics, water leaks – what do these all have in common? The answer is that they could all seem to be caused by either a roof or HVAC system issue. At Dayco Systems, we often receive calls that are not HVAC-related at all. While HVAC issues may appear to be caused by damage to your HVAC, they may be roof issues. Roofing companies, such as our partners, Georgia Roof Advisors, also receive many calls for issues that are HVAC-related, rather than roofing problems. So, our companies have come together to help break down some common issues that are easily confused as to whether they are roof or HVAC related. Keep reading below to see what the most common issues are and which business to call for help!


What’s that rattling noise? Do you hear a clanging sound? It could be a tree hitting your roof and causing potential damage. Or, more than likely, it is coming from your air conditioning unit. Check your air conditioning system and listen for the sound there. The most common reasons for the rattling are components being knocked around in the blower fan, bent fan blades, or a loose fan belt. Many of these occur in older systems, but before you check your roof for debris, check your air conditioning first! While some of these are simple fixes, others can mean a bigger problem that requires professional help.

Issue:  HVAC

Metal Pieces

One of the most easily confused roofing issues is metal pieces on the roof. Many homeowners notice metal sticking up on their roofs and assume that it is some type of damage. However, these are often exhaust components for an HVAC system. They can deteriorate and rust over time and may become more visible or prominent. This can lead to water buildup and affect your roof down the road, so make sure to call your HVAC contractor to determine if a fix is necessary.

Issue: HVAC


A leak on your ceiling can cause us to believe there is roof damage allowing moisture into our home. However, these leaks are often caused by HVAC units. Frozen coils, ductwork issues, or clogged air filters can lead to issues that then lead directly to leaks. Proper maintenance, including annual inspections and regularly changing air filters, can help to prevent situations that cause leaks and potential water damage. If there was a recent storm in your area, it could be storm damage to your roof from debris, so take that into consideration before calling your contractor.

Issue:  HVAC or Roof


When our home suddenly feels warmer in hotter temperatures, we assume our HVAC is having issues or that our air conditioning system has stopped working. There are several reasons why your roof could be causing this issue, rather than your HVAC system. Asphalt shingles are dark and trap more heat, leading to warmer indoor temperatures. Poor roof ventilation and an improperly installed roof can also cause excess warm air, typically within an attic or top floor, making your home feel warmer than it should.
