Answers to the roofing questions we hear most — from doing the work yourself to what your roof needs before we arrive.
Most roofing work should not be done yourself. Manufacturers generally will not give a warranty if you do not have a professional roofer install the product. Professionals are trained to handle the environment on the roof — and the dangers to a homeowner trying to do their own roof work could be a lot more expensive than just hiring a roofing professional to come out and do the work.
Flashings are connections from the roof covering to any protrusion in the roof system or any wall that the roof butts up to. These are critical areas that will allow rain to penetrate if they are not installed and sealed properly.
A roof should have one square foot of net ventilation area for every 150 square feet of attic floor space. Ventilation devices must be fastened or secured to the roof deck to resist wind pressures.
Before roofing contractors arrive each day, move all vehicles from your driveway and the street in front of your house. The roofing contractors bring equipment and work vehicles that need to be close to your home or building.
Installing a new roof over the top of an existing roof is generally acceptable under these guidelines: a building cannot have more than two roofs; no wet insulation can be left in place; the roof structure must be able to handle the additional roof load; and the new roof must be attached to the roof deck to meet wind loads.
Most building codes allow a structure to have two roof membranes in place, but not a third. The codes are also now requiring all roof layers to be removed once the two roof limit has been reached, when looking to install the third roof.
