Some units can be upgraded (for example a lodging unit can be upgraded from accommodating two instead of only one worker). All houses contain at least one unit which is available by purchase via contribution points.

Plus, big enough openings in your roof structure leaves room for critters to get in. Snow shouldn’t be coming in either, as it too can lead to mould and rot. Any signs of mould, rot or bad structure in your roof is a red flag. It means your attic isn’t breathing, which could lead to mould or rot. If you see frost on the sheathing it’s not a good sign. If you have shingles on your roof, as most North American homes do, for every nail that goes through the tar paper there’s a tiny hole - an open invitation for water in your attic.Ĭheck your attic (and garage) after a storm too. This adds a second layer of protection against leaks and moisture, so if water gets in below the shingles the sheathing is watertight.Īnother reason I like ice and water shield is it seals around nails, unlike tar paper, roofing felt or asphalt paper. I also like to see ice and water shield installed over the entire roof, on top of the plywood sheathing (yes, it should be plywood) - not just along the edges near gutters. It can wear it out prematurely and void the warranty on the new shingles. It’s not against code to have two layers of shingles in most regions, but you shouldn’t put more weight and stress on your roof than is necessary. I always recommend removing the first layer of shingles when re-shingling. Add the weight of two layers of shingles and that’s one roof I wouldn’t want over my head. What about the weight of snow itself? If there’s ice too, that can be a heavy load. There needs to be enough space in the roof framing for the right thickness of spray foam to be applied, which provides the necessary R-value. Some municipalities don’t allow them.Ī cathedral roof is one with no attic space, so the underside of the roof should be insulated with spray foam. That’s not healthy for your energy bills or the environment.Ĭathedral ceilings or hot roofs can be prone to heat loss, ice dams, condensation and moisture issues. If your roof is warm enough to melt the snow but it’s cold enough outside for snow to refreeze, your roof is losing heat. A snow-covered roof means your attic is doing its job.Īlso keep an eye out for icicles - another sign of heat loss. It’s normal for some melting around venting and fireplace exhausts, but you shouldn’t see any bare patches on your roof. That means there’s heat loss likely due to poor insulation and/or ventilation in the attic.Īfter a snowfall, every homeowner should take a look at their roof and check for hot spots - areas on the roof where the snow has melted. If your roof gets a decent amount of snow on it, make sure it’s not melting in specific spots. Ice also tends to accumulate on lower-sloped roofs because these roofs are difficult to insulate and ventilate - there often isn’t much room for insulation and air movement in a shallow attic.
