Spring Showers Ahead, it’s a Good Time to Fix a Leaking Attic

April 25, 2018

Whether you’ve got an emergency attic leak, or just a nagging water leak in the roof area, spring is the ideal time to fix a leaking attic. Over time, attics can suffer from water leaks for a number of reasons - all of them resolvable. The key is to do it right the first time, ensuring long-term results.

Finding the source and scope of an attic leak

In order to properly fix a leaking attic, it’s important to source the cause of the leak, and identify the inherent problem. This can sometimes be difficult, especially if there is insulation obscuring the source of the leak. In many homes, it’s quite common for attic leaking to occur around the chimney, attic vents, plumbing vents, and HVAC ducting. This is because of wear and tear, but can also be a result of poor workmanship during installation. For professionals, finding the source of an attic leak is fundamental to fixing the inherent problem. A professional knows where to look and how to spot the telltale signs. Professionals also know the best approach to fix a leaking attic.

Different reasons for leaks and wet attic cavities

Wet attic cavities or persistent water leaks could be a result of many things:  a roofing failure; ice damming; even condensation build-up inside the attic. Needless to say, rainy spring weather will simply exacerbate the leaking and potentially cause damages. When you have a professional on hand to fix a leaking attic, there are definite advantages. It means that every possible attic issue is addressed – from roofing elements, to vapour barriers, to air barriers, to thermal insulation, to ventilation. And it means that the right type of work is done to ensure the best long-term results.

Finding a reliable contractor to fix a leaking attic

Regardless of the leakage issue, attic and roofing repairs should be done right the first time. This is not a time for patchwork or quick fixes – these types of approaches only serve as a “band aid” solution with short-term outcomes. For the attic professionals at Great Northern Insulation, only a comprehensive approach will do - from thorough inspection, to practical recommendations, to quality installations. The team at GNI specializes in preventing water leakage issues, air leakage issues, and attic insulation. They will also address such problems as ice damming and attic condensation. Combining GNI’s specialties with the consultation of a roof inspector goes a long way in ensuring your attic’s structure stays strong and sturdy.

GNI also offers insulation removal/replacement

In any home, the attic requires proper sealing and quality insulation. This will ensure a dry space from season to season, with no potential for moisture collection or water leakage. Great Northern Insulation specializes in spray foam applications – both for air/vapour sealing as well as thermal insulation. Often combined with blown insulation in the attic, the spray foam provides an effective air barrier, vapour barrier, and insulative barrier all in one application. Best of all, Great Northern Insulation will provide you with a reputable product warranty and an installation guarantee.

GreenON Rebate Program offers rebates for installed attic insulation

The GreenON Rebate Program is now available to homeowners who are intending to make upgrades to attic insulation (as well as other energy efficiency improvements). The rebate is designed to help homeowners decrease the carbon footprint of their homes. This is done by offsetting the upfront cost of upgrades, particularly the purchase and installation of newly installed insulation. If you’re ready to upgrade your attic insulation, this is an ideal opportunity to enjoy big savings. By taking full advantage, you could qualify for up to $1,500 for upgrading or retrofitting your attic insulation. Great Northern Insulation can help you with the entire process from start to finish.
