Unventilated attics can help to mitigate energy loss through leaky ducts or ceiling fittings. The energy savings touted by unvented attics can be as high as 20%. However, if moisture is able to enter the unvented attic space, it may lead to roofing panel issues.
The color of the shingles you choose for your build can have a significant impact on the building’s energy efficiency. The color shingles your clients choose can have significant effect on the temperature of the upper levels of the building. Attic temperatures can vary as much as 20 to 40 degrees F which in turn can reduce energy consumption by 20%.
Call-backs for roofing problems don’t come cheap. From mystery noises to leaks, these troublesome tasks can really eat into your already slim profit margins. Here are some regular culprits that can be avoided with just a little more attention to detail during the installation phase.
Ventilating your attic is key to reducing moisture and avoiding mold. Attic ventilation is a critical factor to ensure that moisture and hot summer air issues are addressed correctly. This will help to preserve the structural integrity of your roof system, reduce energy costs in the warm summer months, improve the effectiveness of your insulation in the winter months and prevent the formation of ice dams.
If you have been administering your blower door test at the end of your build, then you may be missing out on an essential opportunity to make your building envelope even tighter. Doing two blower-door tests; one mid-way through your build and one at the end, will give you a unique opportunity to fix cracks and holes before they get covered over by insulation and sheetrock.
When the sun is at a particular angle, you can see the outline of the OSB panels on my roof. This causes a ‘windowpane’ effect. Why is this happening and what can you do to prevent it?
Norbord’s Onsite app helps prevent mistakes and reduces construction time. Onsite enables builders, framers, and DIYers to work effectively with all their OSB products.
Recently we had a call from a builder complaining that their roof sheathing was buckling, causing a telegraphing effect through their roofing shingles. Concerned about the structural efficacy of the roof, they asked us to take a look. The builder and dealer thought it was a number of problems with the roofing panels themselves but, on closer inspection, we discovered that there were a number of installation issues that caused the problem.
The 2015 blizzards have had a calamitous effect on housing over the winter, causing damage and destruction to many roofs. After several feet of snow, buildings across the country began to buckle under the added weight, prompting officials to encourage home owners to clear their roofs of snow. The record-breaking snow, ice and freezing temperatures wreaked havoc on homes with older roofs causing collapses and sagging.
