3 Roofing Myths Debunked
Your roof offers the home's first level of defense against the elements. Taking care of your roof not only prevents leaks and other inconveniences but also prolongs the life of the entire structure.
You probably know that you need your roof in great shape to help your home stand up to ever-changing weather conditions. But with so much information out there, it can be really hard to know what to believe. This article looks to debunk 3 roofing myths to help you sort things out so you can protect your roof better.
Gutters aren't part of the roofing system
Many homeowners make the mistake of neglecting their gutters and downspouts when scheduling roof maintenance, not realizing that both systems are interconnected. Water from your roof shingles flows down to the gutters and downspouts before being diverted away from your home's foundation.
Poorly sloped gutters can cause water backups that could potentially rot away fascia boards, soffits, and sheathing, while clogging in the gutters can contribute to ice dams. Taking care of the gutter system helps prevent serious problems with the entire roof structure. Therefore, reattaching loose downspouts or sagging gutters and clearing gutter pipes of debris should be part of your regular roof maintenance.
Adding more roof insulation improves roof performance
It is easy to assume that increasing the amount of insulation on your roof will translate to better thermal resistance and lower utility bills. However, adding more than the required amount of insulation can be devastating for your roof.
Too much insulation blocks vents, louvers and ridge venting, interfering with the delicate balance between thermal resistance and airflow in your roof. Without proper ventilation, the roof can start trapping moisture at the soffits and eaves which can then promote mold growth or causes the sheathing from the attic interior to wrap and rot.
The amount of insulation used on your roof is most likely balanced to allow for proper ventilation so as to maintain steady attic temperatures and keep moisture at bay, so it is better not to add another layer of fiberglass insulation without consulting a roofing expert.
Flashing doesn't have to be replaced regularly
It is a common misconception that flashing only needs to be replaced when a new roof is being put in place.
Flashing, which is a metal layer installed over the shingles to divert rainwater away from vents, pipes, and the chimney, can cause serious roof damage if not replaced regularly (by professionals such as those from Homestreet Roofing Inc). Be sure to schedule an inspection to check for dried caulking or cracked flashing to prevent water infiltration to the sheathing.
