Frequently Asked Questions

Q. I have a large mirror in my dining room. Do I need to take it out before you re-roof my home?

A: It is a good idea to remove any large or expensive mirrors and pictures from your walls to avoid them possibly falling and becoming damaged.
Please talk with your Keith Green Construction Project Manager about any special concerns.

Q. Can you re-roof my house if it’s raining?

A: Yes, if you’re having a second layer of composition shingles installed.
However, if we are tearing-off your existing roofing we do need to schedule the work for a dry day.

Q. There are some broken tree branches and leaf piles on my roof; do I need to remove them ?

A: Fallen tree branches can damage shingles and other roofing materials. Leaves can retain moisture and can cause rot. Leaves that fall into gutters can block drainage. Your roof should be kept clear of debris.
Keith Green Construction offers roof inspections to help you identify necessary roof repairs and maintenance.

Q. My roof is missing a couple of shingles. How important is it to replace the shingles ?

A: The key to a roof’s effectiveness is complete protection. When your roof has missing or damaged shingles, the roof structure and home interior are vulnerable to water damage. Missing or damaged shingles should be replaced as soon as possible.
Keith Green Construction has many shingle styles and colors available for prompt repairs.

Q. How do I know if I need a tear-off and re-roof, or can just have another layer of shingles on my house ?

A: The current number of layers on your roof will be the primary deciding factor. If your roof currently has only one layer, you can consider a second layer.
However, if your home already has two or more layers or if structural damage is suspected, you’ll need to have all of the roofing removed before having new roofing installed.
This can be especially beneficial to the life of your roof because any underlying structural repairs, such as dry rot or water damage, can be repaired at that time.
Keith Green Construction can tell you what’s best for your roof.

Q. What is Class A Fire Rating ?

A: Roof assemblies play important roles in buildings’ overall abilities to resist fires. For this reason, building codes generally require buildings’ roof assemblies to meet specific fire resistance characteristics. Roof assemblies typically are required to resist the spread of fires originating from buildings’ exteriors and interiors. The specific degree of fire resistance required primarily is based on a buildings construction, occupancy and location.
Roof assemblies’ abilities to resist fires originating on buildings’ exteriors are determined by subjecting representative small-scale specimens of roof assemblies to laboratory testing using one of several recognized standard test methods: ASTM E108, “Standard Test Methods for Fire Tests of Roof Coverings”; UL 790, “Standard for Tests for Fire Resistance of Roof Covering Materials”; or FM 4470, “Approval for Class I Roof Covers.” These test methods provide the basis for Class A, Class B and Class C for fire ratings.
Class A-rated roof assemblies are effective against severe fire test exposure. A “Class A” fire rating is the most stringent rating available for exterior fire resistance. Class B-rated roof assemblies are effective against moderate fire test exposure. A Class C fire rating is the least stringent rating available for exterior fire resistance. If a roof assembly cannot pass the Class C criteria, it typically is considered to be non-classified.”
