Problems with Low Sloped Roofs
Low sloped roofs or flat roofs do not shed water and snow as quickly as steeper roofs, making them more susceptible to leaks or water damage. Because of their design and the fact that many low sloped roofs are older, they are more prone to condensation related problems including leaks and ice dams. These issues are usually caused by heat loss into the attic or ceiling due to poor insulation or vapour barriers. If your roof is older, showing wear and/or damaged these could cause some very expensive home repairs.
More About Ice Dams:
Ice dams form on the edge of your roof, or right on your roof if it is flat, when the underside of your roof in the attic is warming the roof surface and causing the snow to melt. Since water will not drain as well off your low sloped roof, it could freeze and cause an ice build up or “ice dam” and that could cause some serious issues including water leaking into your home as well as damage to your roof’s shingles and eavetroughs.

Proper Roofing System for Low Sloped Roofs
Installing the proper roofing system, including effective membranes, will help reduce or even eliminate the water issues that come with low sloped roofs. Roofing contractors that specialize in low-sloped roofs will ensure the proper ice and water membrane is installed at the eaves edges and beneath the entire roof. This water impermeable and weatherproof membrane should be installed on all roofs that have slopes that are 14 degrees or less.
Then a high quality roofing materials for the protective exterior layer. Exterior layers could be shingles, tar and gravel or a rubber roofing system depending on what will suit your specific roof, home and budget best. A professional roofer will also check and install proper flashing around pipes, chimneys, vents and other openings to ensure maximum protection against leaks and damage.

Preventing Future Roof Damage
Though installing a proper roofing system for your low sloped roof is essential to prevent leaks and damage, you should also consider having an Edmonton insulation contractor inspect your insulation system. If your insulation is older and under performing it will allow heat to escape, causing snow and ice to melt on your low sloped or flat roof. This access of water or potential ice dams could damage your new roof over time. An insulation upgrade will work together with your new roof to maximize energy efficiency and overall protection for your home.
