Roof Suitability

Orientation of roof:

While the ideal position to install solar panels is on a south-facing roof, other orientations can produce sufficient electricity to make solar worthwhile. Most residential installations will be roof mounted. Understanding your home’s location respecting the sun and the shading impact of surrounding structures or trees and their shading are important. A site survey performed by the solar installation company selected by Solarize Houston will ultimately determine the suitability of your home for solar, but it is important for you to understand the basics of this concept.

We recommend that you use Google Maps to input your home address and then look at the satellite (or earth) view to your home’s orientation and roof. Normally, the top of the Google Maps page faces north.

Roof Condition:

Another consideration in the financial evaluation of a solar system is any necessary repairs for your roof. After the system is installed, the roof can be replaced, but there will be the added expense of removing and re-installing the solar PV system. You should consider getting a roofer to inspect your roof if your roof is more than 10 years old or you have any questions about its condition. These may be concerns in a composition roof:

1. The roof is over 15 years old
2. Shingles that are worn, discolored, broken, cracked, or curling.
3. Many shingle granules in the gutters
4. Missing shingles or flashing
5. Sagging roof deck
6. Leaks

A structural engineer, may be hired by the solar installation company may inspect the structural integrity of the roof prior to installing a roof mounted solar system. A structural inspection may be requiredof the permitting and inspection process for local jurisdictions.
