Ventilation plays a vital role in maintaining the air flow of your flat roof. You must install it with extra care and attention to make sure that nothing goes wrong. The more you stay alert and conscious, the better the results would be in the end.
Here are a few tips mentioned to help you install ventilation on a flat roof.
First of all, you need to choose and mark the correct place for your ventilation system before you cut the hole for it. You can then drill a screw into your flat roof through the attic.
However, you must make sure that the vent pipe doesn’t go through any such area of your roof where there is a beam present to support your flat roof. The screw you drive into the attic would act as the central area of your vent pipe.
Now that you have located the position where you would install the ventilation system, you need to remove the shingles around that area.
You must be extra careful while removing the shingles to make sure that you don’t end up ruining any of them.
Cut the Hole
Now you can measure the circumference of the vent pipe twice or thrice to avoid any error. The measurements must be precise to get a right sized hole in your flat roof.
It is advised to leave some room for the expansion. You should use a reciprocating saw properly to cut the hole without damaging the nearby shingles.
First, you must install flashing for your vent by using some roofing tar around the hole. It plays a vital role in making sure that the water doesn’t get inside the attic or under the vent.
The size of the flashing around the hole can be 4 inches approximately. Then, you can nail the flashing into the roof with the perfect and strong nails.
Then you can install the ventilation into the hole by following the instructions of the manufacturer.
It is advised to place the shingles back before placing the cap to see how it would look like after getting finished.
You can replace the shingles once your roof vent is properly installed. If your flat roof has tiles, membrane, or rocks, you can replace them as well. However, you might require the help and expertise of any of the renowned professional roofing contractors in Macomb County Michigan to avoid any disaster.
Install Vent Covering
A vent covering is really important to prevent the water from going into the drain system of your roof. You must place the cover on the top of your ventilation and secure it to make sure that it serves its purpose.
You can waterproof your ventilation system with the use of caulk around the attic. It is better to choose a silicone based caulk to leave some space for the pipe to expand as it is exposed to external weather conditions.
