Is the grammar in this sentence correct and does it sound alright. Its a piece from my research paper.

To give the roof that authentic Cotswold style, stone shingles, which grew smaller and smaller as they ascended toward the peak, were imported from England.

Imported from England,stone shingles, which became smaller and smaller as they ascended toward the peak, were used to give the roof an authentic Cotswold style.

I think rearranging will make the sentence more succinct.

The grammar in the sentence appears to be correct, and it sounds fine. However, here's how you can confirm it for yourself:

1. Check for subject-verb agreement: Ensure that the subject ("stone shingles") agrees with the verb ("were imported").
2. Verify the use of commas: Check if the commas are correctly placed and separate the relevant sections of the sentence. In this case, the commas are used appropriately.
3. Look for proper adverb placement: Confirm the placement of the adverbial phrase ("as they ascended toward the peak") modifying the verb "grew." In this sentence, it is placed correctly.

By following these steps, you can confirm the grammar and flow of the sentence.
