The number of roof vents necessary for a 2,000-square-foot house depends on several factors. The calculation depends on the net free area within the attic and whether your municipality requires a 1/150 or a 1/300 ratio of venting square feet to attic square feet. If you install vents with a square-foot opening of one, you'll need either 14 or seven exhaust vents and an equal square-foot amount of intake vents.

Shingle roofing can last anywhere from 15 to 50 years, depending on the type and quality of shingle, your local climate, and how well you maintain your roof. If you live in an area that sees extreme weather, like strong winds, hail storms, or hurricanes, the average life span of a shingle roof will often be on the shorter end, especially if you choose a more affordable roof shingle that isn’t designed to persist through extreme weather.

EPDM roofs have a few common problems, most of which can be resolved with regular maintenance. This type of roofing is laid down in sheets with seams, which can be a starting point for leaks. Proper installation and roof sealing can often avoid seam issues. 

The material is also susceptible to tears and punctures from falling branches or other sharp objects. There are black and white versions of EPDM, and the black version is more prone to fade and succumb to UV damage. Regular roof inspections can protect the costs of rubber roof installation and extend the life of your roof.

Maybe you waited a little longer than you should have before dealing with the snow accumulation on your roof, and now you are wondering if there is risk of roof collapse. Here are some signs you should look out for: a sagging roof, cracking and cracking sounds, cracks in walls, and leaks in your attic and ceiling.

If you suspect potential roof collapse, do not delay. Take immediate action. Call a professional roofing company and get an inspection. You may want to move your belongings to a safe place and relocate your family until everything has been taken care of.
