There are a number of things that you can do to make sure your fascia and soffits are working properly. As always, we recommend that you get a professional opinion on every part of your roof at least once a year with a professional roofing inspection.
Soffits are a prime space for hornet, wasp, or bee nests. Periodically check for miniature nest formations and use insect killer to take care of the issue. If you’re not comfortable with tackling this on your own, definitely call an exterminator to have the problem taken care of before it grows any larger.
If you find mold or mildew running along your soffits, use a broom or a soft brush doused with bleach and water to mop up the mess. After that, you should schedule a call with a roofing professional to check the underside of your roof for possible water damage and weak points.
We say this a lot, but preventative maintenance is the name of the game when it comes to roofs. Being preemptive about your roofing issues and repairs costs next to nothing when you compare it to a large water-damage repair bill.
