How To Recover A Low Pitch Roof

For commercial buildings one of the other popular low pitch roof options is coated metal.

How to recover a low pitch roof.

No roofshould be dead level flat. A roof that is nearly level or slightly pitched is called a low slope roof. Visiting my sister marlene in thunder bay this summer 2012 there was as usual a project like every other time. Roof reinforcement due to the challenges that low pitch roof systems face low pitch roof design should have necessary reinforcement.

For a roof recover that is keeping the low slope structure a roofer may add tapered insulation and then a new roof covering of epdm or other roofing material. Reshingling a low slope roof and a few things not to do this article covers reshingling a low sloped roof and a few things you should avoid when shingling such a roof. The reinforcement adds strength makes the roof system more resistant and increases the dimensional stability of the membranes. It must have at least a slight slope to drain.

But in some climates such as areas of deep snow cover the property owner may prefer to convert to a more steeply sloped roof structure a procedure we describe at low slope roof conversion 3 4 5. Attach drip edge along the edge of the roof with roofing cement. When the beams span perpendicular to the new roof slope a base shoe is still used dependent on the spacing of the beams in relation to the retrofit purlin s span capacity. Although surprisingly there was only one leak in the old roof.

Metal roofs aren t waterproof in and of themselves but they can be treated with a coating that makes them so. Problems inlow slope roofs are common and more difficult to diagnose than pitched roof problemsbecause the path of water leakage through flat roofs is often quite hard to trace. This coating helps reduce the instances of rust increasing the life span of the roof. Since low slope roofs are more susceptible to leaks the key to making your low slope roof to function well is to increase the waterproofing properties of your roofing system.

For structural concrete roofs on existing buildings the post and purlin system uses base shoes and posts that are installed centered over the existing concrete beams.
