Roof Condition
Hail damaged the shingle roof, the low-slope back porch roof, the roof vents and the gutters on this Westminster ranch home. The roof was replaced through the homeowner's insurance claim. Once the old shingles came off, the tear-off exposed damaged deck boards, with broken sections and open gaps in the original board decking.
- Hail damage to the shingle roof and the low-slope back porch roof
- Hail damage to the roof vents and the gutters
- Damaged deck boards exposed by the tear-off
- Broken sections and open gaps in the original board decking
Evaluation & Approach
Westminster sits in the Front Range hail belt, and this roof had already taken a hit. Replacing it with IKO Nordic, which carries a Class 4 rating under UL 2218, the highest impact rating for shingles, gives the home better protection against the next storm, and many insurers offer a premium discount for it. The porch is too flat for shingles, so it got a self-adhered modified bitumen membrane made for low slopes instead of shingles that would leak. Replacing flashings, vents and gutters at the same time means nothing old is left tied into a new roof. Shingles are only as good as the wood they are nailed to, so broken and gapped boards were replaced instead of covered over.
