If several of these apply to your roof, it’s probably time to consider a full roof replacement. But if it’s not that bad, or contained to one area of the roof, sometimes a repair will work.
A repair can be made when only one section of the roof is in need of new shingles. Chimney flashing and valleys are also a common sources of leaks. These repairs can be made without replacing the whole roof, as can a new skylight installation or other smaller modification.
Stains on the roof are caused by algae (Gloeocapsa Magma), which most commonly appears on roofs with overhanging trees and in older, overgrown neighborhoods. While there are cleaning products for this on the market, these algae stains are very difficult to clean, with most products failing to rid the roof of algae quickly. Your best preventive measure is to install a shingle with algae relief (AR) which have copper or zinc imbedded in the shingle. These elements work as an algaecide. Shingles made by Owens Corning, GAF, and Atlas have algae-resistant products.
Re-Roofs vs Full Roof Replacements
A “Re-Roof” is another term for installing a second layer of shingles over your existing roof. This method will save you money for the short term, but the shingles are less likely to perform as well as a single layer. Leaks are more common on roofs with two layers and repairs are more difficult. 15 years ago we used to occasionally agree to a re-roof when these were more commonplace, but now we strongly recommend against them.
Roofs should never have more than 2 layers; three layers is a fire hazard and a building code violation. “Just say no!”
Homeowners can file an insurance claim under the following conditions:
- Your roof is damaged by wind or hail
- A tree falls on your roof (it makes a sound alright)
- Lightening strike
- Animal damage, if extensive
Working With Insurance Companies
At Lang Home Exteriors, we regularly work with insurance companies and can help guide you through the process. The insurance company will send an adjuster to examine your roof. If they approve the claim, they send a ‘deposit check’ to the homeowner, who may then select a reputable company *ahem* to do the work. The insurance company pays the balance upon completion of the job. Cheers!
