Как сделать КРЫШУ правильно? ОШИБКИ, о которых молчат строители.

How to build a roof without mistakes? In this video, I detail the most common mistakes even experienced builders make when installing a roof, and explain how to build a roof correctly so it will last for decades without rot, ice, frost, or mold. If you want to understand how to build a reliable roof, how to ventilate it, how the ridge, eaves, and gaps work, and where the air escapes—this video is for you. Roof problems are often caused not by the materials, but by improper ventilation. Half of all builders make the same mistakes: blocking the air flow, using improper waterproofing, installing gutters incorrectly, and disrupting the ridge. As a result, the roof stops "breathing," and after a couple of years, residents are faced with wet walls, dripping condensation, and expensive repairs. In this video, I use real-life diagrams to demonstrate how NOT to build a roof, and most importantly, how to build a roof correctly so that ventilation works both in summer and winter under a layer of snow. You'll learn: The three essential factors for proper ventilation; Where and why ventilation most often fails; How to properly position the gutter so that snow doesn't block airflow in winter; Why you shouldn't connect the sheathing at the ridge; When to install vents and when to install high deflectors; How to create a membrane rupture; How to ventilate an attic and a cold loft. If you want to know how to build a roof that will last for decades, watch the video to the end. This guide, based on 20 years of experience, will help you avoid mistakes and make your roof truly reliable. Link to the video "Roof Ventilation.
