This research and writing assignment is very similar to what a home inspector does during a home inspection--researching and studying inspection images and illustrations, studying and referring to and applying a Standards of Practice, taking inspection images, making observations, describing components, determining the condition of those components, formulating opinions, making recommendations to correct (if needed), proposing the implication of not making corrections to a defect (if observed), writing notes, and communicating observations in written form.
Please continue with the course after submitting your essay. If the essay does not meet the criteria, you'll be notified by email to rewrite the essay.
Ice dams can cause serious damage to roofs in areas where there are extended periods with temperatures below 32 degrees. Older homes with poorly insulated and poorly vented attics are very prone ice dam issues. Ice formed along the unheated edge of the roof builds up to create a dam that then backs up water to where it drips through the roof into living areas and inside walls. Thirty or forty years ago it was very common in cold climates to see metal flashing along the bottom three feet of roofs. Current insulation and ventilation guidelines create roofs that are much less likely to have ice dam issues.
Older roofs with ice dam issues usually benefit by having a new metal roof installed. Metal roofs are less penetrable by backed up water, and snow and ice are more likely to slide off.
